Description
DRA77xP and DRA76xP (Jacinto 6 Plus) automotive applications processors are built to meet the intense
processing needs of the modern digital cockpit automobile experiences.
The device enables Original-Equipment Manufacturers (OEMs) and Original-Design Manufacturers
(ODMs) to quickly implement innovative connectivity technologies, speech recognition, audio streaming,
and more. Jacinto 6 Plus devices bring high processing performance through the maximum flexibility of a
fully integrated mixed processor solution. The devices also combine programmable video processing with
a highly integrated peripheral set.
ADVANCE INFORMATION
Programmability is provided by dual-core ARM Cortex-A15 RISC CPUs with Neon™ extension, TI C66x
VLIW floating-point DSP core, and Vision AccelerationPac (with one or more EVEs). The ARM allows
developers to keep control functions separate from other algorithms programmed on the DSP and
coprocessors, thus reducing the complexity of the system software.
Additionally, TI provides a complete set of development tools for the ARM, DSP, and EVE coprocessor,
including C compilers and a debugging interface for visibility into source code.
Cryptographic acceleration is available in all devices. All other supported security features, including
support for secure boot, debug security and support for trusted execution environment are available on
High-Security (HS) devices. For more information about HS devices, contact your TI representative.
The DRA77xP and DRA76xP Jacinto 6 Plus processor family is qualified according to the AEC-Q100
standard.

(1) DSS clock jitter can be improved by providing an external clock source (via inputs vin1a_clk, vin1b_clk) or from internal SATA or PCIe PLLs.
(2) Device supports ISS as an optional feature if the part number is designated with the “I” option
(3) USB4 will not be supported on some pin-compatible roadmap devices. USB3 will be mapped to these balls instead. Pin compatibility can be maintained in the future by either not using
USB4, or via software change to use USB4 on this device, but USB3 on these balls in the future.
(4) In the Unified L3 memory map, there is maximum of 2GB of SDRAM space which is available to all L3 initiators including MPU (MPU, GPU, DSP, IVA, DMA, etc). Typically this space is
interleaved across both EMIFs to optimize memory performance. If a system populates > 2GB of physical memory, that additional addressable space can be accessed only by the MPU

Table 4-1 describes the terminal characteristics and the signals multiplexed on each ball. The following list
describes the table column headers:
1. BALL NUMBER: Ball number(s) on the bottom side associated with each signal on the bottom.
2. BALL NAME: Mechanical name from package device (name is taken from muxmode 0).
3. SIGNAL NAME: Names of signals multiplexed on each ball (also notice that the name of the ball is the
signal name in muxmode 0).
NOTE
Table 4-1 does not take into account the subsystem multiplexing signals. Subsystem
multiplexing signals are described in Section 4.3, Signal Descriptions.
NOTE
In the Driver off mode, the buffer is configured in high-impedance.
4. 76xP: This column shows if the functionality is applicable for DRA76xP devices. Note that the Pin
Attributes table presents the functionality of DRA77xP device. An empty box means "Yes".
5. MUXMODE: Multiplexing mode number:
a. MUXMODE 0 is the primary mode; this means that when MUXMODE=0 is set, the function
mapped on the pin corresponds to the name of the pin. The primary muxmode is not necessarily
the default muxmode.
NOTE
The default mode is the mode at the release of the reset; also see the RESET REL.

ADVANCE INFORMATION
b. MUXMODE 1 through 15 are possible muxmodes for alternate functions. On each pin, some
muxmodes are effectively used for alternate functions, while some muxmodes are not used. Only
MUXMODE values which correspond to defined functions should be used.
c. An empty box means Not Applicable
6. TYPE: Signal type and direction:
– I = Input
– O = Output
– IO = Input or Output
– D = Open drain
– DS = Differential Signaling
– A = Analog
– PWR = Power
– GND = Ground
– CAP = LDO Capacitor
7. BALL RESET STATE: The state of the terminal at power-on reset:
– drive 0 (OFF): The buffer drives VOL (pulldown or pullup resistor not activated)
– drive 1 (OFF): The buffer drives VOH (pulldown or pullup resistor not activated)
– OFF: High-impedance
– PD: High-impedance with an active pulldown resistor
– PU: High-impedance with an active pullup resistor
– An empty box means Not Applicable
8. BALL RESET REL. STATE: The state of the terminal at the deactivation of the rstoutn signal (also
mapped to the PRCM SYS_WARM_OUT_RST signal)
– drive 0 (OFF): The buffer drives VOL (pulldown or pullup resistor not activated)
– drive clk (OFF): The buffer drives a toggling clock (pulldown or pullup resistor not activated)
– drive 1 (OFF): The buffer drives VOH (pulldown or pullup resistor not activated)
– OFF: High-impedance
– PD: High-impedance with an active pulldown resistor
– PU: High-impedance with an active pullup resistor
– An empty box means Not Applicable
NOTE
For more information on the CORE_PWRON_RET_RST reset signal and its reset sources,
see the Power Reset and Clock Management / PRCM Reset Management Functional
Description section of the Device TRM.
9. BALL RESET REL. MUXMODE: This muxmode is automatically configured at the release of the
rstoutn signal (also mapped to the PRCM SYS_WARM_OUT_RST signal).
An empty box means Not Applicable.
10. IO VOLTAGE VALUE: This column describes the IO voltage value (the corresponding power supply).
An empty box means Not Applicable.
11. POWER: The voltage supply that powers the terminal IO buffers.
An empty box means Not Applicable.
12. HYS: Indicates if the input buffer is with hysteresis:
– Yes: With hysteresis
– No: Without hysteresis
– An empty box: Not Applicable
NOTE
For more information, see the hysteresis values in Section 5.7, Electrical Characteristics.

13. BUFFER TYPE: Drive strength of the associated output buffer.
An empty box means Not Applicable.
NOTE
14. PULLUP / PULLDOWN TYPE: Denotes the presence of an internal pullup or pulldown resistor.
Pullup and pulldown resistors can be enabled or disabled via software.
– PU: Internal pullup
– PD: Internal pulldown
– PU/PD: Internal pullup and pulldown
– PUx/PDy: Programmable internal pullup and pulldown
– PDy: Programmable internal pulldown
– An empty box means No pull
15. DSIS: The deselected input state (DSIS) indicates the state driven on the peripheral input (logic "0" or
logic "1") when the peripheral pin function is not selected by any of the PINCNTLx registers.
– 0: Logic 0 driven on the peripheral's input signal port.
– 1: Logic 1 driven on the peripheral's input signal port.
– blank: Pin state driven on the peripheral's input signal port.
NOTE
Configuring two pins to the same input signal is not supported as it can yield unexpected
results. This can be easily prevented with the proper software configuration (Hi-Z mode is not
an input signal).
NOTE
When a pad is set into a multiplexing mode which is not defined by pin multiplexing, that
pad’s behavior is undefined. This should be avoided.
CAUTION
Peripherals exposed in Pin Attributes Table and Pin Multiplexing Table
represent functionality of a DRA77xP device. Not all exposed peripherals are
supported on DRA7xx devices. For peripherals supported on DRA7xx family of
products please refer to Table 3-1, Device Comparison.
NOTE
Some of the DDR1 and DDR2 signals have an additional state change at the release of porz.
The state that the signals change to at the release of porz is as follows:
drive 0 (OFF) for: ddr1_csn0, ddr1_ck, ddr1_nck, ddr1_nck, ddr1_casn, ddr1_rasn,
ddr1_wen, ddr1_ba[2:0], ddr1_a[15:0], ddr2_csn0, ddr2_ck, ddr2_nck, ddr2_casn, ddr2_rasn,
ddr2_wen, ddr2_ba[2:0], ddr2_a[15:0].
OFF for: ddr1_ecc_d[7:0], ddr1_dqm[3:0], ddr1_dqm_ecc, ddr1_dqs[3:0], ddr1_dqsn[3:0],
ddr1_dqs_ecc, ddr1_dqsn_ecc, ddr1_d[31:0], ddr2_dqm[3:0], ddr2_dqs[3:0], ddr2_dqsn[3:0],
ddr2_d[31:0].

(4) The output impedance settings of this IO cell are programmable; by default, the value is DS[1:0] = 10, this means 40 Ω. For more information on DS[1:0] register configuration, see the
Device TRM.
(5) IO drive strength for usb1_dp, usb1_dm, usb2_dp and usb2_dm: minimum 18.3 mA, maximum 89 mA (for a power supply vdda33v_usb1 and vdda33v_usb2 = 3.46 V).
(6) Minimum PU = 900 Ω, maximum PU = 3.090 kΩ and minimum PD = 14.25 kΩ, maximum PD = 24.8 kΩ.
For more information, see chapter 7 of the USB2.0 specification, in particular section Signaling / Device Speed Identification.
(7) This function will not be supported on some pin-compatibleroadmap devices. Pin compatibility can be maintained in the future by not using these GPIO signals.
(8) In PUx / PDy, x and y = 60 to 200 μA.
The output impedance settings (or drive strengths) of this IO are programmable (34 Ω, 40 Ω, 48 Ω, 60 Ω, 80 Ω) depending on the values of the I[2:0] registers.
(9) This signal is valid only for High-Security devices. For more details, see Section 5.8 VPP Specification for One-Time Programmable (OTP) eFUSEs. For General Purpose devices do not
connect any signal, test point, or board trace to this signal.

(1) This clock signal is implemented as 'pad loopback' inside the device - the output signal is looped back through the input buffer to serve
as the internal reference signal. Series termination is recommended (as close to device pin as possible) to improve signal integrity of the
clock input. Any nonmonotonicity in voltage that occurs at the pad loopback clock pin between VIH and VIL must be less than VHYS.
(2) The gpio6_16.clkout1 signal can be used as an “always-on” alternative to gpmc_clk provided that the external device can support the
associated timing. See Table 5-52, GPMC/NOR Flash Interface Switching Characteristics - Synchronous Mode - Default Mode and
Table 5-54, GPMC/NOR Flash Interface Switching Characteristics - Synchronous Mode - Alternate Mode for timing information.
(3) The internal pull resistors for balls H6, G6, J4, F5, J3, H4, H3, H5 are permanently disabled when sysboot15 is set to 1 as described in
the section Sysboot Configuration of the Device TRM. If internal pull-up/down resistors are desired on these balls then sysboot15 should
be set to 0. If gpmc boot mode is used with SYSBOOT15=1 (not recommended) then external pull-downs should be implemented to
keep the address bus at logic-0 value during boot since the gpmc ms-address bits are Hi-Z during boot.

RMII_MHZ_50_C RMII Reference Clock (50 MHz). This pin is an input when external reference is
LK(1)
used or output when internal reference is used.
(1) This clock signal is implemented as 'pad loopback' inside the device - the output signal is looped back through the input buffer to serve
as the internal reference signal. Series termination is recommended (as close to device pin as possible) to improve signal integrity of the
clock input. Any non-monotonicity in voltage that occurs at the pad loopback clock pin between VIH and VIL must be less than VHYS.
(2) Note that rstoutn is only valid after vddshv3 is valid. If the rstoutn signal will be used as a reset into other devices attached to the SOC, it
must be AND'ed with porz. This will prevent glitches occurring during supply ramping being propagated.

Pin Multiplexing
Table 4-33 describes the device pin multiplexing (no characteristics are provided in this table).
NOTE
Table 4-33, Pin Multiplexing doesn't take into account subsystem multiplexing signals. Subsystem multiplexing signals are described in
Section 4.3, Signal Descriptions.
NOTE
ADVANCE INFORMATION
For more information, see the Control Module / Control Module Functional Description / PAD Functional Multiplexing and Configuration
section of the Device TRM.
NOTE
Configuring two pins to the same input signal is not supported as it can yield unexpected results. This can be easily prevented with the
proper software configuration. (Hi-Z mode is not an input signal.)
NOTE
In some cases Table 4-33 may present more than one signal name per muxmode for the same ball. First signal in the list is the dominant
function as selected via CTRL_CORE_PAD_* register. All other signals are virtual functions that present alternate multiplexing options.
This virtual functions are controlled via CTRL_CORE_ALT_SELECT_MUX or CTRL_CORE_VIP_MUX_SELECT register. For more
information on how to use this options, please refer to the Device TRM, Chapter Control Module, Section Pad Configuration Registers.
NOTE
When a pad is set into a pin multiplexing mode which is not defined, that pad’s behavior is undefined. This should be avoided.
CAUTION
The I/O timings provided in Section 5.10, Timing Requirements and Switching Characteristics are valid only if signals
within a single IOSET are used. The IOSETs are defined in the corresponding tables.

(2) The voltage at the device ball should never be below the MIN voltage or above the MAX voltage for any amount of time. This
requirement includes dynamic voltage events such as AC ripple, voltage transients, voltage dips, etc.
ADVANCE INFORMATION
(3) The DC voltage at the device ball should never be above the MAX DC voltage to avoid impact on device reliability and lifetime POH
(Power-On-Hours). The MAX DC voltage is defined as the highest allowed DC regulated voltage, without transients, seen at the ball.
(4) If DDR2 type of memories are used, the EMIF power supply (vdds_ddrx) and the corresponding bias power supply (vdds18v_ddrx) must
be sourced from single power source.
(5) Logic functions and parameter values are not assured out of the range specified in the recommended operating conditions.

(1) In a typical implementation, the power supply should target the NOM voltage.
(2) The voltage at the device ball should never be below the MIN voltage or above the MAX voltage for any amount of time. This
requirement includes dynamic voltage events such as AC ripple, voltage transients, voltage dips, etc.
(3) The DC voltage at the device ball should never be above the MAX DC voltage to avoid impact on device reliability and lifetime POH
(Power-On-Hours). The MAX DC voltage is defined as the highest allowed DC regulated voltage, without transients, seen at the ball.
(4) For all OPPs, AVS must be enabled to avoid impact on device reliability, lifetime POH (Power-On-Hours), and device power.
(5) The AVS Voltages are device-dependent, voltage domain-dependent, and OPP-dependent. They must be read from the
STD_FUSE_OPP. For information about STD_FUSE_OPP Registers address, please refer to Control Module Section of the Device
TRM. The power supply should be adjustable over the following ranges for each required OPP:
– OPP_NOM for MPU: 0.85V – 1.15V
– OPP_NOM for CORE and Others: 0.85V - 1.15V
– OPP_OD: 0.885V - 1.15V
– OPP_HIGH: 0.95V - 1.25V
– OPP_PLUS: 0.95V - 1.25V
The AVS Voltages will be within the above specified ranges.
(6) The power supply must be programmed with the AVS voltages for the MPU and the CORE voltage domain, either just after the ROM
boot or at the earliest possible time in the secondary boot loader before there is significant activity seen on these domains.

Maximum Supported Frequency
Device modules either receive their clock directly from an external clock input, directly from a PLL, or from
a PRCM. Table 5-5 lists the clock source options for each module on this device, along with the maximum
frequency that module can accept. To ensure proper module functionality, the device PLLs and dividers
must be programmed not to exceed the maximum frequencies listed in this table.

(1) VITH is the voltage at which the receiver is required to detect a high state in the input signal.
(2) VITL is the voltage at which the receiver is required to detect a low state in the input signal. VITL is larger than the maximum single-ended
line high voltage during HS transmission. Therefore, both low-power (LP) receivers will detect low during HS signaling.
(3) To reduce noise sensitivity on the received signal, the LP receiver is required to incorporate a hysteresis, VHYST. VHYST is the difference
between the VITH threshold and the VITL threshold.
(4) VITL is the voltage at which the receiver is required to detect a low state in the input signal. Specification is relaxed for detecting 0 during
ultralow power (ULP) state. The LP receiver is not required to detect HS single-ended voltage as 0 in this state.
(5) Excluding possible additional RF interference of 200 mVPP beyond 450 MHz.
(6) This value includes a ground difference of 50 mV between the transmitter and the receiver, the static common-mode level tolerance and
variations below 450 MHz.
(7) This number corresponds to the VODMAX transmitter.
(8) Common mode is defined as the average voltage level of X and Y: VCMRX = (VX + VY) / 2.

(9) Common mode ripple may be due to tR or tF and transmission line impairments in the PCB.

5.10.1.1.3 Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data manual do not include delays by board routes. As a
good board design practice, such delays must always be taken into account. Timing values may be
adjusted by increasing/decreasing such delays. TI recommends using the available I/O buffer information
specification (IBIS) models to analyze the timing characteristics correctly. To properly use IBIS models to
attain accurate timing analysis for a given system, see the Using IBIS Models for timing Analysis
application report (literature number SPRA839). If needed, external logic hardware such as buffers may be
used to compensate any timing differences.
5.10.2 Interface Clock Specifications
5.10.2.1 Interface Clock Terminology
The interface clock is used at the system level to sequence the data and/or to control transfers accordingly
with the interface protocol.
The two interface clock characteristics are:
• The maximum clock frequency
• The maximum operating frequency
The interface clock frequency documented in this document is the maximum clock frequency, which
corresponds to the maximum frequency programmable on this output clock. This frequency defines the
maximum limit supported by the Device IC and does not take into account any system consideration
(PCB, peripherals).
The system designer will have to consider these system considerations and the Device IC timing
characteristics as well to define properly the maximum operating frequency that corresponds to the
maximum frequency supported to transfer the data on this interface.
5.10.3 Power Supply Sequences
This section describes the power-up and power-down sequence required to ensure proper device
operation. The power supply names described in this section comprise a superset of a family of
compatible devices. Some members of this family will not include a subset of these power supplies and
their associated device modules. Refer to the Section 4.2, Pin Attributes of the Section 4, Terminal
Configuration and Functions to determine which power supplies are applicable.

Manager Functional Description section of the Device TRM.
NOTE
The device operation requires the following clocks:
• The 32 kHz frequency is used for low frequency operation. It supplies the wake-up domain for
operation in lowest power mode. This is an optional clock and will be supplied by on chip divider + mux
(FUNC_32K_CLK) incase it is not available on external pin.
• The system clocks, SYS_CLKIN1(Mandatory) and SYS_CLKIN2(Optional) are the main clock sources
of the device. They supply the reference clock to the DPLLs as well as functional clock to several
modules.
The Device also embeds an internal free-running 32-kHz oscillator that is always active as long as the the
wake-up (WKUP) domain is supplied.

(1) To switch from bypass mode to crystal or from crystal mode to bypass mode, there is a waiting time about 100 μs; however, if the chip
comes from bypass mode to crystal mode the crystal will start-up after time mentioned in Table 5-22, tsX parameter.
(2) Before the processor boots up and the oscillator is set to bypass mode, there is a waiting time when the internal oscillator is in
application mode and receives a wave. The switching time in this case is about 100 μs.

5.10.4.4 DPLLs, DLLs
NOTE
For more information, see:
• Power, Reset and Clock Management / Clock Management Functional / Internal Clock
Sources / Generators / Generic DPLL Overview Section
and
• Display Subsystem / Display Subsystem Overview section of the Device TRM.
To generate high-frequency clocks, the device supports multiple on-chip DPLLs controlled directly by the
PRCM module. They are of two types: type A and type B DPLLs.
They have their own independent power domain (each one embeds its own switch and can be
controlled as an independent functional power domain)
• They are fed with ALWAYS ON system clock, with independent control per DPLL.
The different DPLLs managed by the PRCM are listed below:
• DPLL_MPU: It supplies the MPU subsystem clocking internally.
• DPLL_IVA: It feeds the IVA subsystem clocking.
• DPLL_CORE: It supplies all interface clocks and also few module functional clocks.
• DPLL_PER: It supplies several clock sources: a 192-MHz clock for the display functional clock, a
96-MHz functional clock to subsystems and peripherals.
• DPLL_ABE: It provides clocks to various modules within the device.
• DPLL_USB: It provides 960M clock for USB modules (USB1/2/3/4).
• DPLL_GMAC: It supplies several clocks for the Gigabit Ethernet Switch (GMAC_SW).
• DPLL_EVE: It provides the Embedded Vision Engine Subsystem (EVE1 and EVE2) clocking.
• DPLL_DSP: It feeds the DSP Subsystem clocking.
• DPLL_GPU: It supplies clock for the GPU Subsystem.
• DPLL_DDR: It generates clocks for the two External Memory Interface (EMIF) controllers and their
associated EMIF PHYs.
• DPLL_PCIE_REF: It provides reference clock for the APLL_PCIE in PCIE Subsystem.
• APLL_PCIE: It feeds clocks for the device Peripheral Component Interconnect Express (PCIe)
controllers.
NOTE
The following DPLLs are controlled by the clock manager located in the always-on Core
power domain (CM_CORE_AON):
• DPLL_MPU, DPLL_IVA, DPLL_CORE, DPLL_ABE, DPLL_DDR, DPLL_GMAC,
DPLL_PCIE_REF, DPLL_PER, DPLL_USB, DPLL_EVE, DPLL_DSP, DPLL_GPU,
APLL_PCIE_REF.
For more information on CM_CORE_AON and CM_CORE or PRCM DPLLs, see the Power, Reset, and
Clock Management (PRCM) chapter of the Device TRM.

5.10.4.4.1 DPLL Characteristics
The DPLL has three relevant input clocks. One of them is the reference clock (CLKINP) used to generated
the synthesized clock but can also be used as the bypass clock whenever the DPLL enters a bypass
mode. It is therefore mandatory. The second one is a fast bypass clock (CLKINPULOW) used when
selected as the bypass clock and is optional. The third clock (CLKINPHIF) is explained in the next
paragraph.
The DPLL has three output clocks (namely CLKOUT, CLKOUTX2, and CLKOUTHIF). CLKOUT and
CLKOUTX2 run at the bypass frequency whenever the DPLL enters a bypass mode. Both of them are
generated from the lock frequency divided by a post-divider (namely M2 post-divider). The third clock,
CLKOUTHIF, has no automatic bypass capability. It is an output of a post-divider (M3 post-divider) with
the input clock selectable between the internal lock clock (Fdpll) and CLKINPHIF input of the PLL through
an asynchronous multplexing.

5.10.5 Recommended Clock and Control Signal Transition Behavior
All clocks and control signals must transition between VIH and VIL (or between VIL and VIH) in a monotonic
manner. Monotonic transitions are more easily guaranteed with faster switching signals. Slower input
transitions are more susceptible to glitches due to noise and special care should be taken for slow input

(1) The CFG_MMC3_CLK_IN register should remain at its Default value, which is programmed automatically by hardware during the recalibration process.
Manual IO Timings Modes must be used to guarantee some IO timings for VIP2. See Table 5-29 Modes Summary for a list of IO timings requiring
the use of Manual IO Timings Modes. See Table 5-36 Manual Functions Mapping for VIP2 for a definition of the Manual modes.
Table 5-36 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.

SPRS993C – MARCH 2017 – REVISED DECEMBER 2017
5.10.6.4 DSS
Three Display Parallel Interfaces (DPI) channels are available in DSS named DPI Video Output 1, DPI
Video Output 2 and DPI Video Output 3.
NOTE
The DPI Video Output i (i = 1 to 3) interface is also referred to as VOUTi.
Every VOUT interface consists of:
• 24-bit data bus (data[23:0])
• Horizontal synchronization signal (HSYNC)
• Vertical synchronization signal (VSYNC)
• Data enable (DE)
• Field ID (FID)
• Pixel clock (CLK)
ADVANCE INFORMATION
NOTE
For more information, see the Display Subsystem chapter of the Device TRM.
CAUTION
The IO timings provided in this section are only valid if signals within a single
IOSET are used. The IOSETs are defined in the Table 5-45 and Table 5-46.
CAUTION
The IO Timings provided in this section are only valid for some DSS usage
modes when the corresponding Virtual IO Timings or Manual IO Timings are
configured as described in the tables found in this section.
CAUTION
All pads/balls configured as vouti_* signals are recommended to use slow slew
rate by setting the corresponding CTRL_CORE_PAD_*[SLEWCONTROL]
register field to SLOW (0b1). FAST slew setting is allowed, but results in faster
edge rates on the VOUTn bus, higher power/ground noise, and higher EMI
emissions compared to SLOW slew rate.
Table 5-41, Table 5-42 and Figure 5-18 assume testing over the recommended operating conditions and
electrical characteristic conditions.

5.10.6.8 Timers
The device has 16 general-purpose (GP) timers (TIMER1 - TIMER16), two watchdog timers, and a 32-kHz
synchronized timer (COUNTER_32K) that have the following features:
• Dedicated input trigger for capture mode and dedicated output trigger/pulse width modulation (PWM)
signal
• Interrupts generated on overflow, compare, and capture
• Free-running 32-bit upward counter
• Supported modes:
– Compare and capture modes
– Auto-reload mode
– Start-stop mode
• On-the-fly read/write register (while counting)
ADVANCE INFORMATION
The device has two system watchdog timer (WD_TIMER1 and WD_TIMER2) that have the following
features:
• Free-running 32-bit upward counter
• On-the-fly read/write register (while counting)
• Reset upon occurrence of a timer overflow condition
The device includes one instance of the 32-bit watchdog timer: WD_TIMER2, also called the MPU
watchdog timer.
The watchdog timer is used to provide a recovery mechanism for the device in the event of a fault
condition, such as a non-exiting code loop.
NOTE
For additional information on the Timer Module, see the Device TRM.
5.10.6.9 I2C
The device includes 5 inter-integrated circuit (I2C) modules which provide an interface to other devices
compliant with Philips Semiconductors Inter-IC bus (I2C-bus™) specification version 2.1. External
components attached to this 2-wire serial bus can transmit/receive 8-bit data to/from the device through
the I2C module.
NOTE
Note that, on I2C1 and I2C2, due to characteristics of the open drain IO cells, HS mode is
not supported
NOTE
Inter-integrated circuit i ( i=1 to 5) module is also referred to as I2Ci
NOTE
For more information, see the Multimaster High-Speed I2C Controller section of the Device
TRM.

pF
(1) The I2C pins SDA and SCL do not feature fail-safe I/O buffers. These pins could potentially draw current when the device is powered
down.
(2) A Fast-mode I2C-bus™ device can be used in a Standard-mode I2C-bus system, but the requirement tsu(SDA-SCLH)? 250 ns must then be
met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch
the LOW period of the SCL signal, it must output the next data bit to the SDA line tr max + tsu(SDA-SCLH)= 1000 + 250 = 1250 ns
(according to the Standard-mode I2C-Bus Specification) before the SCL line is released.
(3) A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the
undefined region of the falling edge of SCL.
(4) The maximum th(SDA-SCLL) has only to be met if the device does not stretch the low period [tw(SCLL)] of the SCL signal.
(5) Cb = total capacitance of one bus line in pF. If mixed with HS-mode devices, faster fall-times are allowed.

(1) I2C HS-Mode is only supported on I2C3/4/5. I2C HS-Mode is not supported on I2C1/2.
(2) For bus line loads Cb between 100 and 400 pF the timing parameters must be linearly interpolated.
(3) A device must internally provide a Data hold time to bridge the undefined part between VIH and VIL of the falling edge of the SCLH
signal. An input circuit with a threshold as low as possible for the falling edge of the SCLH signal minimizes this hold time.

(1) Cb = total capacitance of one bus line in pF. If mixed with HS-mode devices, faster fall-times are allowed.
(2) Software must properly configure the I2C module registers to achieve the timings shown in this table. See the Device TRM for details.
(3) These timings apply only to I2C1 and I2C2. I2C3, I2C4, and I2C5 use standard LVCMOS buffers to emulate open-drain buffers and their
rise/fall times should be referenced in the device IBIS model.
NOTE
ADVANCE INFORMATION
I2C emulation is achieved by configuring the LVCMOS buffers to output Hi-Z instead of
driving high when transmitting logic-1.

5.10.6.11 UART
The UART performs serial-to-parallel conversions on data received from a peripheral device and parallelto-serial conversion on data received from the CPU. There are 10 UART modules in the device. Only one
UART supports IrDA features. Each UART can be used for configuration and data exchange with a
number of external peripheral devices or interprocessor communication between devices
The UARTi (where i = 1 to 10) include the following features:
• 16C750 compatibility
• 64-byte FIFO buffer for receiver and 64-byte FIFO for transmitter
• Baud generation based on programmable divisors N (where N = 1…16 384) operating from a fixed
functional clock of 48 MHz or 192 MHz

5.10.6.12 McSPI
The McSPI is a master/slave synchronous serial bus. There are four separate McSPI modules (SPI1,
SPI2, SPI3, and SPI4) in the device. All these four modules support up to four external devices (four chip
selects) and are able to work as both master and slave.
ADVANCE INFORMATION
The McSPI modules include the following main features:
• Serial clock with programmable frequency, polarity, and phase for each channel
• Wide selection of SPI word lengths, ranging from 4 to 32 bits
• Up to four master channels, or single channel in slave mode
• Master multichannel mode:
– Full duplex/half duplex
– Transmit-only/receive-only/transmit-and-receive modes
– Flexible input/output (I/O) port controls per channel
– Programmable clock granularity
– SPI configuration per channel. This means, clock definition, polarity enabling and word width
• Power management through wake-up capabilities
• Programmable timing control between chip select and external clock generation
• Built-in FIFO available for a single channel.
• Each SPI module supports multiple chip select pins spim_cs[i], where i = 1 to 4.
NOTE
For more information, see the Serial Communication Interface section of the device TRM.
NOTE
The McSPIm module (m = 1 to 4) is also referred to as SPIm.
CAUTION
The IO timings provided in this section are applicable for all combinations of
signals for SPI1 and SPI2. However, the timings are only valid for SPI3 and
SPI4 if signals within a single IOSET are used. The IOSETS are defined in the
Table 5-71.

The Quad SPI (QSPI) module is a type of SPI module that allows single, dual or quad read access to
external SPI devices. This module has a memory mapped register interface, which provides a direct
interface for accessing data from external SPI devices and thus simplifying software requirements. It
works as a master only. There is one QSPI module in the device and it is primary intended for fast
booting from quad-SPI flash memories.
General SPI features:
• Programmable clock divider
• Six pin interface (DCLK, CS_N, DOUT, DIN, QDIN1, QDIN2)
• 4 external chip select signals
• Support for 3-, 4- or 6-pin SPI interface
• Programmable CS_N to DOUT delay from 0 to 3 DCLKs
• Programmable signal polarities
• Programmable active clock edge
• Software controllable interface allowing for any type of SPI transfer
NOTE
For more information, see the Quad Serial Peripheral Interface section of the Device TRM.
CAUTION
The IO Timings provided in this section are only valid for some QSPI usage
modes when the corresponding Virtual IO Timings or Manual IO Timings are
configured as described in the tables found in this section.
CAUTION
The IO Timings provided in this section are only valid when all QSPI Chip
Selects used in a system are configured to use the same Clock Mode (either
Clock Mode 0 or Clock Mode3).
Table 5-72 and Table 5-73 present Timing and Switching Characteristics for Quad SPI Interface.

(1) The Y parameter is defined as follows:
If DCLK_DIV is 0 or ODD then, Y equals 0.5.
If DCLK_DIV is EVEN then, Y equals (DCLK_DIV/2) / (DCLK_DIV+1).
For best performance, it is recommended to use a DCLK_DIV of 0 or ODD to minimize the duty cycle distortion. The HSDIVIDER on
CLKOUTX2_H13 output of DPLL_PER can be used to achieve the desired clock divider ratio. All required details about clock division
factor DCLK_DIV can be found in the device TRM.
(2) P = SCLK period.
(3) M = QSPI_SPI_DC_REG.DDx + 1 when Clock Mode 0.
M = QSPI_SPI_DC_REG.DDx when Clock Mode 3.
N = 2 when Clock Mode 0.
N = 3 when Clock Mode 3.

5.10.6.14 McASP
The multichannel audio serial port (McASP) functions as a general-purpose audio serial port optimized for the needs of multichannel audio
applications. The McASP is useful for time-division multiplexed (TDM) stream, Inter-Integrated Sound (I2S) protocols, and inter-component digital
audio interface transmission (DIT).
The device have integrated 8 McASP modules (McASP1-McASP8) with:
• McASP1 and McASP2 modules supporting 16 channels with independent TX/RX clock/sync domain
• McASP3 through McASP8 modules supporting 4 channels with independent TX/RX clock/sync domain
NOTE
For more information, see the Multichannel Audio Serial Port section of the Device TRM.
CAUTION
The IO Timings provided in this section are only valid for some McASP usage modes when the corresponding Virtual IO
Timings or Manual IO Timings are configured as described in the tables found in this section.

TXC is delayed internally before being driven to the rgmiin_txc pin. This internal delay is always enabled.
Data and control information is transmitted using both edges of the clocks. rgmiin_txd[3:0] carries data bits 3-0 on the
rising edge of rgmiin_txc and data bits 7-4 on the falling edge of rgmiin_txc. Similarly, rgmiin_txctl carries TXEN on
rising edge of rgmiin_txc and TXERR of falling edge of rgmiin_txc.

NOTE
To configure the desired Manual IO Timing Mode the user must follow the steps described in
section Manual IO Timing Modes of the Device TRM.
The associated registers to configure are listed in the CFG REGISTER column. For more
information see the Control Module chapter in the Device TRM.
Manual IO Timings Modes must be used to guarantee some IO timings for MMC2. See Table 5-29 Modes
Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 5-150 Manual
Functions Mapping for MMC2 with Internal Loopback Clock and for HS200 for a definition of the Manual
modes.
Table 5-150 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in
the CFG_x registers.

5.10.6.22 GPIO
The general-purpose interface combines eight general-purpose input/output (GPIO) banks. Each GPIO
module provides 32 dedicated general-purpose pins with input and output capabilities; thus, the generalpurpose interface supports up to 245 pins.
These pins can be configured for the following applications:
• Data input (capture)/output (drive)
• Keyboard interface with a debounce cell
• Interrupt generation in active mode upon the detection of external events. Detected events are
processed by two parallel independent interrupt-generation submodules to support biprocessor
operations
• Wake-up request generation in idle mode upon the detection of external events

Trace Port Interface Unit (TPIU)
Advanced Event Triggering Interface (AET)
5.10.7.1 JTAG
The JTAG (IEEE Standard 1149.1-1990 Standard-Test-Access Port and Boundary Scan Architecture)
interface is used for BSDL testing and emulation of the device. The trstn pin only needs to be released
when it is necessary to use a JTAG controller to debug the device or exercise the device's boundary scan
functionality. For maximum reliability, the device includes an internal Pulldown (IPD) on the trstn pin to
ensure that trstn is always asserted upon power up and the device's internal emulation logic is always
properly initialized. JTAG controllers from Texas Instruments actively drive trstn high. However, some
third-party JTAG controllers may not drive trstn high but expect the use of a Pullup resistor on trstn. When
using this type of JTAG controller, assert trstn to initialize the device after powerup and externally drive
trstn high before attempting any emulation or boundary-scan operations.
ADVANCE INFORMATION
The main JTAG features include:
• 32KB embedded trace buffer (ETB)
• 5-pin system trace interface for debug
• Supports Advanced Event Triggering (AET)
• All processors can be emulated via JTAG ports
• All functions on EMU pins of the device:
– EMU[1:0] - cross-triggering, boot mode (WIR), STM trace
– EMU[4:2] - STM trace only (single direction)

The TMS320C66x DSP core enhances the TMS320C674x™ core, which merges the C674x™ floating
point and the C64x+™ fixed-point instruction set architectures. The C66x DSP is object-code compatible
with the C64x+/C674x DSPs.
For more information on the TMS320C66x core CPU, see the TMS320C66x DSP CPU and Instruction Set
Reference Guide, (SPRUGH7).
The DSP subsystem integrated in the device includes the following components:
• A TMS320C66x™ CorePac DSP core that encompasses:
– L1 program-dedicated (L1P) cacheable memory
– L1 data-dedicated (L1D) cacheable memory
– L2 (program and data) cacheable memory
– Extended Memory Controller (XMC)

– DSP CorePac located interrupt controller (INTC)
– DSP CorePac located power-down controller (PDC)
• Dedicated enhanced data memory access engine - EDMA, to transfer data from/to memories and
peripherals external to the DSP subsystems and to local DSP memory (most commonly L2 SRAM).
The external DMA requests are passed through DSP system level (SYS) wakeup logic, and collected
from the DSP1 / DSP2 dedicated outputs of the device DMA Events Crossbar for each of the two
subsystems.
• A level 2 (L2) interconnect network (DSP NoC) to allow connectivity between different modules of the
subsystem or the remainder of the device via the device L3_MAIN interconnect.
• Two memory management units (on EDMA L2 interconnect and DSP MDMA paths) for accessing the
device L3_MAIN interconnect address space
• Dedicated system control logic (DSP_SYSTEM) responsible for power management, clock generation,
and connection to the device power, reset, and clock management (PRCM) module
The TMS320C66x Instruction Set Architecture (ISA) is the latest for the C6000 family. As with its
predecessors (C64x, C64x+ and C674x), the C66x is an advanced VLIW architecture with 8 functional
units (two multiplier units and six arithmetic logic units) that operate in parallel. The C66x CPU has a total
of 64 general-purpose 32-bit registers.
Some features of the DSP C6000 family devices are:
• Advanced VLIW CPU with eight functional units (two multipliers and six ALUs) which:
– Executes up to eight instructions per cycle for up to ten times the performance of typical DSPs

• Exceptions support for error detection and program redirection to provide robust code execution
• Hardware support for modulo loop operation to reduce code size and allow interrupts during fullypipelined code
• Each multiplier can perform 32 × 32 bit multiplies
• Additional instructions to support complex multiplies allowing up to eight 16-bit multiply/add/subtracts
per clock cycle
The TMS320C66x has the following key improvements to the ISA:
• 4x Multiply Accumulate improvement for both fixed and floating point
• Improvement of the floating point arithmetic
• Enhancement of the vector processing capability for fixed and floating point
• Addition of domain-specific instructions for complex arithmetic and matrix operations
On the C66x ISA, the vector processing capability is improved by extending the width of the SIMD
instructions. The C674x DSP supports 2-way SIMD operations for 16-bit data and 4-way SIMD
operations for 8-bit data. C66x enhances this capabilities with the addition of SIMD instructions for 32-bit
data allowing operation on 128-bit vectors. For example the QMPY32 instruction is able to perform the
element to element multiplication between two vectors of four 32-bit data each.
C66x ISA includes a set of specific instructions to handle complex arithmetic and matrix operations.

C66x DSP subsystem (DSPSS) safety aspects:
– Above mentioned memory ECC/ED mechanisms
– MMUs enable mapping of only the necessary application space to the processor
– Memory Protection Units internal to the DSPSS (in L1P, L1D and L2 memory controllers) and
external to DSPSS (firewalls) to help define legal accesses and raise exceptions on illegal
accesses
– Exceptions: Memory errors, various DSP errors, MMU errors and some system errors are detected
and cause exceptions. The exceptions could be handled by the DSP or by a designated safety
processor at the chip level. Note that it may not be possible for the safety processor to completely
handle some exceptions
Unsupported features on the C66x DSP core for the device are:
• The Extended Memory Controller MPAX (memory protection and address extension) 36-bit addressing
is NOT supported
Known DSP subsystem powermode restrictions for the device are:
• "Full logic / RAM retention" mode featuring wake-up on both interrupt or DMA event (logic in “always
on” domain). Only OFF mode is supported by DSP subsystem, requiring full boot.

6.11 ATL Overview
The audio tracking logic (ATL) is used by HD Radio™ applications to synchronize the digital audio output
to the baseband clock. This same IP can also be used generically to track errors between two reference
signals (such as frame syncs) and generate a modulated clock output (using software-controlled cycle
stealing) which averages to some desired frequency. This process can be used as a hardware assist for
asynchronous sample rate conversion algorithms. The tracking range is limited, so direct conversion
between the two standard sample rate groups frequencies from 44.1 to 48 kHz is not possible.
The ATL includes the following main features:
• One ATL module, containing four ATL instances, for HD Radio support and asynchronous sample rate
conversion assistance
• Each instance tracks the time error between two syncs (local audio word select [AWS] and baseband
word select [BWS])
• Each instance selects between 16 mux choices for each of AWS and BWS.
• Each instance generates modulated ATCLK_OUT clock signal with software-initiated pulse stealing.

• Software Generated Interrupts (SGIs): SGIs are generated by writing to the Cortex-A15 Software
Generated Interrupt Register (GICD_SGIR). A maximum of 16 SGIs (ID0–ID15) can be generated for
each CPU interface. An SGI has edge-triggered properties. The software triggering of the interrupt is
equivalent to the edge transition of the interrupt signal on a peripheral input.
• Private Peripheral Interrupts (PPIs): A PPI is an interrupt generated by a peripheral that is specific to a
single processor. Although interrupts ID16–ID31 are dedicated to PPIs in general, only seven PPIs are
actually used for each CPU interface (ID25–ID31). Interrupts ID16–ID24 are reserved (not used).
• Shared Peripheral Interrupts (SPIs): SPIs are triggered by events generated on associated interrupt
input lines. In this device, the GIC is configured to support 160 SPIs corresponding to its external
IRQS[159:0] signals.
For detailed information about this module and description of SGIs and PPIs, see the ARM Cortex-A15
MP Core Technical Reference Manual (available at infocenter.arm.com/help/index.jsp).
C66x DSP Subsystem Interrupt Controller (DSPx_INTC, where x = 1, 2)
There are two Digital Signal Processing (DSP) subsystems in the device - DSP1, and DSP2. Each DSP
subsystem integrates an interrupt controller - DSPx_INTC, which interfaces the system events to the C66x
core interrupt and exceptions inputs. It combines up to 128 interrupts into 12 prioritized interrupts
presented to the C66x CPU.
For detailed information about this module, see chapter DSP Subsystems of the Device TRM.
Dual Cortex-M4 IPU Subsystem Interrupt Controller (IPUx_Cx_INTC, where x = 1, 2)
There are two Image Processing Unit (IPU) subsystems in the device - IPU1, and IPU2. Each IPU
subsystem integrates two ARM Cortex-M4 cores.
A Nested Vectored Interrupt Controller (NVIC) is integrated within each Cortex-M4. The interrupt mapping
is the same (per IPU) for the two cores to facilitate parallel processing. The NVIC supports:
• 64 external interrupts (in addition to 16 Cortex-M4 internal interrupts), which are dynamically prioritized
with 16 levels of priority defined for each core
• Low-latency exception and interrupt handling
• Prioritization and handling of exceptions
• Control of the local power management
• Debug accesses to the processor core

6.15 EDMA
The primary purpose of the Enhanced Direct Memory Access (EDMA) controller is to service userprogrammed data transfers between two memory-mapped slave endpoints on the device.
The EDMA controller consists of two major principle blocks:
• EDMA Channel Controller
• EDMA Transfer Controller(s)
The EDMA Channel Controller (EDMACC) serves as the user interface for the EDMA controller. The
EDMACC includes parameter RAM (PaRAM), channel control registers, and interrupt control registers.
The EDMACC serves to prioritize incoming software requests or events from peripherals and submits
transfer requests (TR) to the EDMA transfer controller.
The EDMA Transfer Controller (EDMATC) is responsible for data movement. The transfer request packets
(TRP) submitted by the EDMACC contain the transfer context, based on which the transfer controller
issues read/write commands to the source and destination addresses programmed for a given transfer.
There are two EDMA controllers present on this device:
• EDMA_0, integrating:
– 1 Channel Controller, referenced as: EDMACC_0
– 2 Transfer Controllers, referenced as: EDMACC_0_TC_0 (or EDMATC_0) and EDMACC_0_TC_1
(or EDMATC_1)
• EDMA_1, integrating:
– 1 Channel Controller, referenced as: EDMACC_1
– 2 Transfer Controllers, referenced as: EDMACC_1_TC_0 (or EDMATC_2) and EDMACC_1_TC_1
(or EDMATC_3)
The two EDMA channel controllers (EDMACC_0 and EDMACC_1) are functionally identical. For
simplification, the unified name EDMACC shall be regularly used throughout this chapter when referring to
EDMA Channel Controllers functionality and features.
The four EDMA transfer controllers (EDMACC_0_TC_0, EDMACC_0_TC_1, EDMACC_1_TC_0 and
EDMACC_1_TC_1) are functionally identical. For simplification, the unified name EDMATC shall be
regularly used throughout this chapter when referring to EDMA Transfer Controllers functionality and
features.
Each EDMACC has the following features:
• Fully orthogonal transfer description
– 3 transfer dimensions:
• Array (multiple bytes)
• Frame (multiple arrays)
• Block (multiple frames)
– Single event can trigger transfer of array, frame, or entire block
– Independent indexes on source and destination

SPRS993C – MARCH 2017 – REVISED DECEMBER 2017
www.ti.com
The PCI Express standard predecessor - PCI, is a parallel bus architecture that is increasingly difficult to
scale-up in bandwidth, which is usually performed by increasing the number of data signal lines. The PCIe
architecture was developed to help minimize I/O bus bottlenecks within systems and to provide the
necessary bandwidth for high-speed, chip-to-chip, and board-to-board communications within a system. It
is designed to replace the PCI-based shared, parallel bus signaling technology that is approaching its
practical performance limits while simplifying the interface design.
The device instantiates two PCIe subsystems (PCIe_SS1 and PCIe_SS2). The PCIe controller is capable
to operate either in Root Complex (RC) or in End Point (EP) PCIe mode. The device PCIe_SS1 controller
supports up to two 16-bit data lanes on its PIPE port. The device PCIe_SS2 controller supports only one
16-bit data lane on its PIPE port.
ADVANCE INFORMATION
When the PCIe_SS1 controller PIPE port is configured to operate in a single-lane mode, it operates on a
single pair of PCIe PHY serializer and deserializer - PCIe1_PHY_TX/PCIe1_PHY_RX. When PCIe_SS1
PIPE is configured to operate in dual-lane mode, it operates on two pairs of PCIe PHY serializer and
deserializer - PCIe1_PHY_TX/PCIe1_PHY_RX and PCIe2_PHY_TX/PCIe2_PHY_RX, respectively. The
single-lane PCIe_SS2 controller PIPE port (if enabled) can operate only on the
PCIe2_PHY_TX/PCIe2_PHY_RX pair. Hereby, if PCIe_SS2 controller is used, the PCIe_SS1 can operate
only in a single-lane mode on the PCIe1_PHY_TX/PCIe1_PHY_RX. In addition, PCIe PHY subsystem
encompasses a PCIe PCS (physical coding sublayer), a PCIe power management logic, APLL, a DPLL
reference clock generator and an APLL clock low-jitter buffer.
• The PCIe Controller implements the transport and link layers of the PCIe interface protocol.
• PCIe PCS (a physical coding sublayer component) converts a 8-bit portion of parallel data over a PCIe
lane to a 10-bit parallel data to adapt the process of serialization and deserialization in the TX/RX
PHYs to various requirements. At the same time it transforms the transmission rate to maintain the

ADVANCE INFORMATION
An effective PWM peripheral must be able to generate complex pulse width waveforms with minimal CPU
overhead or intervention. It needs to be highly programmable and very flexible while being easy to
understand and use. The ePWM unit described here addresses these requirements by allocating all
needed timing and control resources on a per PWM channel basis. Cross coupling or sharing of resources
has been avoided; instead, the ePWM is built up from smaller single channel modules with separate
resources and that can operate together as required to form a system. This modular approach results in
an orthogonal architecture and provides a more transparent view of the peripheral structure, helping users
to understand its operation quickly.

For more information, see section Enhanced Capture (eCAP) Module in chapter Pulse-Width Modulation
Subsystem of the device TRM.
6.16.21 eQEP
A single track of slots patterns the periphery of an incremental encoder disk. These slots create an
alternating pattern of dark and light lines. The disk count is defined as the number of dark/light line pairs
that occur per revolution (lines per revolution). As a rule, a second track is added to generate a signal that
occurs once per revolution (index signal: QEPI), which can be used to indicate an absolute position.
Encoder manufacturers identify the index pulse using different terms such as index, marker, home
position, and zero reference.
ADVANCE INFORMATION
To derive direction information, the lines on the disk are read out by two different photo-elements that
"look" at the disk pattern with a mechanical shift of 1/4 the pitch of a line pair between them. This shift is
realized with a reticle or mask that restricts the view of the photo-element to the desired part of the disk
lines. As the disk rotates, the two photo-elements generate signals that are shifted 90 degrees out of
phase from each other. These are commonly called the quadrature QEPA and QEPB signals. The
clockwise direction for most encoders is defined as the QEPA channel going positive before the QEPB
channel.
The encoder wheel typically makes one revolution for every revolution of the motor or the wheel may be at
a geared rotation ratio with respect to the motor. Therefore, the frequency of the digital signal coming from
the QEPA and QEPB outputs varies proportionally with the velocity of the motor. For example, a 2000-line
encoder directly coupled to a motor running at 5000 revolutions per minute (rpm) results in a frequency of
166.6 KHz, so by measuring the frequency of either the QEPA or QEPB output, the processor can
determine the velocity of the motor.
For more information, see section Enhanced Quadrature Encoder Pulse (eQEP) Module in chapter PulseWidth Modulation Subsystem of the device TRM.
6.17 On-Chip Debug
Debugging a system that contains an embedded processor involves an environment that connects highlevel debugging software running on a host computer to a low-level debug interface supported by the
target device. Between these levels, a debug and trace controller (DTC) facilitates communication
between the host debugger and the debug support logic on the target chip.
The DTC is a combination of hardware and software that connects the host debugger to the target system.
The DTC uses one or more hardware interfaces and/or protocols to convert actions dictated by the
debugger user to JTAG® commands and scans that execute the core hardware.
The debug software and hardware components let the user control multiple central processing unit (CPU)
cores embedded in the device in a global or local manner. This environment provides:
• Synchronized global starting and stopping of multiple processors
• Starting and stopping of an individual processor
• Each processor can generate triggers that can be used to alter the execution flow of other processors
System topics include but are not limited to:
• System clocking and power-down issues
• Interconnection of multiple devices
• Trigger channels

7 Applications, Implementation, and Layout
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test design implementation to confirm system functionality.
7.1
Introduction
This chapter is intended to communicate, guide and illustrate a PCB design strategy resulting in a PCB
that can support TI’s latest Application Processor. This Processor is a high-performance processor
designed for automotive Infotainment and Advanced Driver Assistance Systems based on enhanced
OMAP™ architecture integrated on a 28-nm CMOS process technology.
ADVANCE INFORMATION
These guidelines first focus on designing a robust Power Delivery Network (PDN) which is essential to
achieve the desirable high performance processing available on Device. The general principles and stepby-step approach for implementing good power integrity (PI) with specific requirements will be described
for the key Device power domains.
TI strongly believes that simulating a PCB’s proposed PDN is required for first pass PCB design success.
Key Device processor high-current power domains need to be evaluated for Power Rail IR Drop,
Decoupling Capacitor Loop-Inductance and Power Rail Target Impedance. Only then can a PCB’s PDN
performance be truly accessed by comparing these model PI parameters vs. TI’s recommended values.
Ultimately for any high-volume product, TI recommends conducting a “Processor PDN Validation” test on
prototype PCBs across processor “split lots” to verify PDN robustness meets desired performance goals
for each customer’s worst-case scenario. Please contact your TI representative to receive guidance on
PDN PI modeling and validation testing.
Likewise, the methodology and requirements needed to route Device high-speed, differential interfaces
(i.e. USB2.0, USB3.0, HDMI, PCI, SATA), single-ended interfaces (i.e. DDR2/DDR3, QSPI) and general
purpose interfaces using LVCMOS drivers that meet timing requirements while minimizing signal integrity
(SI) distortions on the PCB’s signaling traces. Signal trace lengths and flight times are aligned with FR-4
standard specification for PCBs.
Several different PCB layout stack-up examples have been presented to illustrate a typical number of
layers, signal assignments and controlled impedance requirements. Different Device interface signals
demand more or less complexity for routing and controlled impedance stack-ups. Optimizing the PCB’s
PDN stack-up needs with all of these different types of signal interfaces will ultimately determine the final
layer count and layer assignments in each customer’s PCB design.
This guideline must be used as a supplement in complement to TI’s Application Processor, Power
Management IC (PMIC) and Audio Companion components along with other TI component technical
documentation (i.e. Technical Reference Manual, Data Manual, Data Sheets, Silicon Errata, Pin-Out
Spreadsheet, Application Notes, etc.).

NOTE
These PCB guidelines are in a draft maturity and consequently, are subject to change
depending on design verification testing conducted during IC development and validation.
Note also that any references to Application Processor’s ballout or pin muxing are subject to
change following the processor’s ballout maturity.
7.1.1
Initial Requirements and Guidelines
Unless otherwise specified, the characteristic impedance for single-ended interfaces is recommended to
be between 35 Ω and 65 Ω to minimize the overshoot or undershoot on far-end loads.
Characteristic impedance for differential interfaces must be routed as differential traces on the same layer.
The trace width and spacing must be chosen to yield the recommended differential impedance. For more
information see Section 7.5.1.
An external interface using a connector must be protected following the IEC61000-4-2 level 4 system
ESD.

Power Optimizations
This section describes the necessary steps for designing a robust Power Distribution Network (PDN):
• Section 7.2.1, Step 1: PCB Stack-up
• Section 7.2.2, Step 2: Physical Placement
• Section 7.2.3, Step 3: Static Analysis
• Section 7.2.4, Step 4: Frequency Analysis
7.2.1
Step 1: PCB Stack-up
The PCB stack-up (layer assignment) is an important factor in determining the optimal performance of the
power distribution system. An optimized PCB stack-up for higher power integrity performance can be
achieved by following these recommendations:
• Power and ground plane pairs must be closely coupled together. The capacitance formed between the
planes can decouple the power supply at high frequencies. Whenever possible, the power and ground
planes must be solid to provide continuous return path for return current.
• Use a thin dielectric between the power and ground plane pair. Capacitance is inversely proportional to
the separation of the plane pair. Minimizing the separation distance (the dielectric thickness)
maximizes the capacitance.
• Optimize the power and ground plane pair carrying high current supplies to key component power
domains as close as possible to the same surface where these components are placed (see Figure 71). This will help to minimize “loop inductance” encountered between supply decoupling capacitors and
component supply inputs and between power and ground plane pairs.
NOTE
1-2oz Cu weight for power / ground plane is preferred to enable better PCB heat spreading,
helping to reduce Processor junction temperatures. In addition, it is preferable to have the
power / ground planes be adjacent to the PCB surface on which the Processor is mounted.

Figure 7-1. Minimize Loop Inductance With Proper Layer Assignment
ADVANCE INFORMATION
The placement of power and ground planes in the PCB stackup (determined by layer assignment) has a
significant impact on the parasitic inductances of power current path as shown in Figure 7-1. For this
reason, it is recommended to consider layer order in the early stages of the PCB PDN design cycle,
putting high-priority supplies in the top half of the stackup (assuming high load and priority components
are mounted on the top-side of PCB) and low-priority supplies in the bottom half of the stackup as shown
in the examples below (vias have parasitic inductances which impact the bottom layers more, so it is
advised to put the sensitive and high-priority power supplies on the top/same layers).
Two PCB stack-ups with layer assignments and via types that can enable an optimize PDN are shown in

Step 2: Physical Placement
A critical step in designing an optimized PDN is that proper care must be taken to making sure that the
initial floor planning of the PCB layout is done with good power integrity design guidelines in mind. The
following points are important for optimizing a PCB’s PDN:
• Minimizing the physical distance between power sources and key high load components is the first
step toward optimization. Placing source and load components on the same side of the PCB is
desirable. This will minimize via inductance impact for high current loads and steps
• External trace routing between components must be as wide as possible. The wider the traces, the
lower the DC resistance and consequently the lower the static IR drop.
• Whenever possible for the internal layers (routing and plane), wide traces and copper area fills are
preferred for PDN layout. The routing of power nets in plane provide for more interplane capacitance
and improved high frequency performance of the PDN.
• Whenever possible, use a via to component pin/pad ratio of 1:1 or better (i.e. especially decoupling
capacitors, power inductors and current sensing resistors). Do not share vias among multiple
capacitors for connecting power supply and ground planes.
• Placement of vias must be as close as possible or even within a component’s solder pad if the PCB
technology you are using provides this capability.
Figure 7-4 shows an example of acceptable width for power net routing but with poor via placement.

Step 3: Static Analysis
ADVANCE INFORMATION
Delivering reliable power to circuits is always of critical importance because voltage drops (also known as
IR drops) can happen at every level within an electronic system, on-chip, within a package, and across the
board. Robust system performance can only be ensured by understanding how the system elements will
perform under typical stressful Use Cases. Therefore, it is a good practice to perform a Static or DC
Analysis.
Static or DC analysis and design methodology results in a PDN design that minimizes voltage or IR drops
across power and ground planes, traces and vias. This ensures the application processor’s internal
transistors will be operating within their specified voltage ranges for proper functionality. The amount of IR
drop that will be encounter is based upon amount power drawn for a desired Use Case and PCB trace
(widths, geometry and number of parallel traces) and via (size, type and number) characteristics.
Components that are distant from their power source are particularly susceptible to IR drop. Designs that
rely on battery power must minimize voltage drops to avoid unacceptable power loss that can negatively
impact system performance. Early assessments a PDN’s static (DC) performance helps to determine
basic power distribution parameters such as best system input power point, optimal PCB layer stackup,
and copper area needed for load currents.

Figure 7-9. Depiction of Sheet Resistivity and Resistance
Ohm’s Law (V = I × R) relates conduction current to voltage drop. At DC, the relation coefficient is a
constant and represents the resistance of the conductor. Even current carrying conductors will dissipate
power at high currents even though their resistance may be very small. Both voltage drop and power
dissipation are proportional to the resistance of the conductor.
Figure 7-10 shows a PCB-level static IR drop budget defined between the power management device
(PMIC) pins and the application processor’s balls when the PMIC is supplying power.
• It is highly recommended to physically place the PMIC as close as possible to the processor and on
the same side. The orientation of the PMIC vs. processor should be aligned to minimize distance for
the highest current rail.

The system-level IR drop budget is made up of three portions: on-chip, package, and PCB board. Static IR
or DC analysis/design methodology consists of designing the PDN such that the voltage drop (under DC
operating conditions) across power and ground pads of the transistors of the application processor device
is within a specified value of the nominal voltage for proper functionality of the device.
A PCB system-level voltage drop budget for proper device functionality is typically 1.5% of nominal
voltage. For a 1.35-V supply, this would be ≤20 mV.
To accurately analyze PCB static IR drop, the actual geometry of the PDN must be modeled properly and
simulated to accurately characterize long distribution paths, copper weight impacts, electro-migration
violations of current-carrying vias, and “Swiss-cheese” effects via placement has on power rails. It is
recommended to perform the following analyses:
• Lumped resistance/IR drop analysis
• Distributed resistance/IR drop analysis
NOTE
The PMIC companion device supporting Processor has been designed with voltage sensing
feedback loop capabilities that enable a remote sense of the SMPS output voltage at the
point of use.
The NOTE above means the SMPS feedback signals and returns must be routed across PCB and
connected to the Device input power ball for which a particular SMPS is supplying power. This feedback
loop provides compensation for some of the voltage drop encountered across the PDN within limits. As
such, the effective resistance of the PDN within this loop should be determined in order to optimize
voltage compensation loop performance. The resistance of two PDN segments are of interest: one from
the power inductor/bulk power filtering capacitor node to the Processor’s input power and second is the
entire PDN route from SMPS output pin/ball to the Processor input power.
In the following sections each methodology is described in detail and an example has been provided of
analysis flow that can be used by the PCB designer to validate compliance to the requirements on their
PCB PDN design.
7.2.3.1
PDN Resistance and IR Drop
Lumped methodology consists of grouping all of the power pins on both the PMIC (voltage source) and
processor (current sink) devices. Then the PMIC source is set to an expected Use Case voltage level and
the processor load has its Use Case current sink value set as well. Now the lumped/effective resistance
for the power rail trace/plane routes can be determine based upon the actual layout’s power rail etch wide,
shape, length, via count and placement Figure 7-11 illustrates the pin-grouping/lumped concept.

The lumped methodology consists of importing the PCB layout database (from Cadence Allegro tool or
any other layout design tool) into the static IR drop modeling and simulation tool of preference for the PCB
designer. This is followed by applying the correct PCB stack-up information (thickness, material
properties) of the PCB dielectric and metallization layers. The material properties of dielectric consist of
permittivity (Dk) and loss tangent (Df).
For the conductor layers, the correct conductivity needs to be programmed into the simulation tool. This is
followed by pin-grouping of the power and ground nets, and applying appropriate voltage/current sources.
The current and voltage information can be obtained from the power and voltage specifications of the
device under different operating conditions / Use Cases.

Step 4: Frequency Analysis
Delivering low noise voltage sources are very important to allowing a system to operate at the lowest
possible Operational Performance Point (OPP) for any one Use Case. An OPP is a combination of the
supply voltage level and clocking rate for key internal processor domains. A SCH and PCB designed to
provide low noise voltage supplies will then enable the processor to enter optimal OPPs for each Use
Case that in turn will minimize power dissipation and junction temperatures on-die. Therefore, it is a good
engineering practice to perform a Frequency Analysis over the key power domains.
Frequency analysis and design methodology results in a PDN design that minimizes transient noise
voltages at the processor’s input power balls. This allows the processor’s internal transistors to operate
near the minimum specified operating supply voltage levels. To accomplish this one must evaluate how a
voltage supply will change due to impedance variations over frequency. This analysis will focus on the
decoupling capacitor network (VDD_xxx and VSS/Gnd rails) at the load. Sufficient capacitance with a
distribution of self-resonant points will provide for an overall lower impedance vs frequency response for
each power domain.
Decoupling components that are distant from their load’s input power are susceptible to encountering
spreading loop inductance from the PCB design. Early analysis of each key power domain’s frequency
response helps to determine basic decoupling capacitor placement, optimal footprint, layer assignment,
and types needed for minimizing supply voltage noise/fluctuations due to switching and load current
transients.
NOTE
Evaluation of loop inductance values for decoupling capacitors placed ~300mils closer to the
load’s input power balls has shown an 18% reduction in loop inductance due to reduced
distance.
•

Decoupling capacitors must be carefully placed in order to minimize loop inductance impact on supply
voltage transients. A real capacitor has characteristics not only of capacitance but also inductance and
resistance.
Figure 7-12 shows the parasitic model of a real capacitor. A real capacitor must be treated as an RLC
circuit with effective series resistance (ESR) and effective series inductance (ESL).

Because a capacitor has series inductance and resistance that impacts its effectiveness, it is important
that the following recommendations are adopted in placing capacitors on the PDN.
Wherever possible, mount the capacitor with the geometry that minimizes the mounting inductance and
resistance. This was shown earlier in Figure 7-1. The capacitor mounting inductance and resistance
values include the inductance and resistance of the pads, trace, and vias. Whenever possible, use
footprints that have the lowest inductance configuration as shown in Figure 7-15

The length of a trace used to connect a capacitor has a big impact on parasitic inductance and resistance
of the mounting. This trace must be as short and as wide as possible. wherever possible, minimize
distance to supply and Gnd vias by locating vias nearby or within the capacitor’s solder pad landing.
Further improvements can be made to the mounting by placing vias to the side of capacitor lands or
doubling the number of vias as shown in Figure 7-15. If the PCB manufacturing processes allow it and if
cost-effective, via-in-pad (VIP) geometries are strongly recommended.
In addition to mounting inductance and resistance associated with placing a capacitor on the PCB, the
effectiveness of a decoupling capacitor also depends on the spreading inductance and resistance that the
capacitor sees with respect to the load. The spreading inductance and resistance is strongly dependent on
the layer assignment in the PCB stack-up. Therefore, try to minimize X, Y and Z dimensions where the Z
is due to PCB thickness (as shown in Figure 7-2).

layout area in order to minimize Dcap loop inductance to power pin as much as possible (see Figure 715).
2. Place Dcaps on “same-side” as component within their power plane outline to minimize “decoupling

layout characteristics (plane's layer assignment and solid nature). Use PI modeling CAD tool to verify

feasible or if distance to power pin is greater than ~500mils for top-side location. Use PI modeling CAD
tool to verify minimum inductance for top vs bottom-side placement.
4. Use minimum 10mil trace width for all voltage and gnd planes connections (i.e. Dcap pads, component
power pins, etc.).
5. Place all voltage and gnd plane vias “as close as possible” to point of use (i.e. Dcap pads, component
power pins, etc.).
6. Use a “Power/Gnd pad/pin to via” ratio of 1:1 whenever possible. Do not exceed 2:1 ratio for small
number of vias within restricted PCB areas (i.e. underneath BGA components).

PDN Reff meets the maximum recommended PDN resistance of 10mΩ.
System ESD Generic Guidelines
7.2.5.1
System ESD Generic PCB Guideline
Protection devices must be placed close to the ESD source which means close to the connector. This
allows the device to subtract the energy associated with an ESD strike before it reaches the internal
circuitry of the application board.
To help minimize the residual voltage pulse that will be built-up at the protection device due to its nonzero
turn-on impedance, it is mandatory to route the ESD device with minimum stub length so that the lowresistive, low-inductive path from the signal to the ground is granted and not increasing the impedance
between signal and ground.
For ESD protection array being railed to a power supply when no decoupling capacitor is available in close
vicinity, consider using a decoupling capacitor (≥ 0.1 µF) tight to the VCC pin of the ESD protection. A
positive strike will be partially diverted to this capacitance resulting in a lower residual voltage pulse.
Ensure that there is sufficient metallization for the supply of signals at the interconnect side (VCC and
GND in Figure 7-16) from connector to external protection because the interconnect may see between 15A to 30-A current in a short period of time during the ESD event.

the ESD protection to the board ground rather than any local ground (example isolated shield
or audio ground).

Miscellaneous EMC Guidelines to Mitigate ESD Immunity
Avoid running critical signal traces (clocks, resets, interrupts, control signals, and so forth) near PCB
edges.
Add high frequency filtering: Decoupling capacitors close to the receivers rather than close to the
drivers to minimize ESD coupling.
Put a ground (guard) ring around the entire periphery of the PCB to act as a lightning rod.
Connect the guard ring to the PCB ground plane to provide a low impedance path for ESD-coupled
current on the ring.
Fill unused portions of the PCB with ground plane.
Minimize circuit loops between power and ground by using multilayer PCB with dedicated power and
ground planes.
Shield long line length (strip lines) to minimize radiated ESD.
Avoid running traces over split ground planes. It is better to use a bridge connecting the two planes in
one area.

Figure 7-17. Trace Examples
Always route signal traces and their associated ground returns as close to one another as possible to
minimize the loop area enclosed by current flow:
– At high frequencies current follows the path of least inductance.
– At low frequencies current flows through the path of least resistance.
EMI / EMC Issues Prevention
All high-speed digital integrated circuits can be sources of unwanted radiation, which can affect nearby
sensitive circuitry and cause the final product to have radiated emissions levels above the limits allowed
by the EMC regulations if some preventative steps are not taken.
Likewise, analog and digital circuits can be susceptible to interference from the outside world and picked
up by the circuitry interconnections.
To minimize the potential for EMI/EMC issues, the following guidelines are recommended to be followed.
7.2.6.1
Signal Bandwidth
To evaluate the frequency of a digital signal, an estimated rule of thumb is to consider its bandwidth fBW
with respect to its rise time, tR:
fBW ≈ 0.35 / tR
This frequency actually corresponds to the break point in the signal spectrum, where the harmonics start
to decay at 40 dB per decade instead of 20 dB per decade.
7.2.6.2
Signal Routing
7.2.6.2.1 Signal Routing—Sensitive Signals and Shielding
Keep radio frequency (RF) sensitive circuitry (like GPS receivers, GSM/WCDMA, Bluetooth/WLAN
transceivers, frequency modulation (FM) radio) away from high-speed ICs (the device, power and audio
manager, chargers, memories, and so forth) and ideally on the opposite side of the PCB. For improved
protection it is recommended to place these emission sources in a shield can. If the shield can have a
removable lid (two-piece shield), ensure there is low contact impedance between the fence and the lid.
Leave some space between the lid and the components under it to limit the high-frequency currents
induced in the lid. Limit the shield size to put any potential shield resonances above the frequencies of
interest; see Figure 7-14, Typical Impedance Profile of a Capacitor.
7.2.6.2.2 Signal Routing—Outer Layer Routing
In case there is a need to use the outer layers for routing outside of shielded areas, it is recommended to
route only static signals and ensure that these static signals do not carry any high-frequency components
(due to parasitic coupling with other signals). In case of long traces, make provision for a bypass capacitor
near the signal source.

SPRS993C – MARCH 2017 – REVISED DECEMBER 2017
www.ti.com
Routing of high-frequency clock signals on outer layers, even for a short distance, is discouraged,
because their emissions energy is concentrated at the discrete harmonics and can become significant
even with poor radiators.
Coplanar shielding of traces on outer layers (placing ground near the sides of a track along its length) is
effective only if the distance between the trace sides and the ground is smaller that the trace height above
the ground reference plane. For modern multilayer PCBs this is often not possible, so coplanar shielding
will not be effective. Do not route high-frequency traces near the periphery of the PCB, as the lack of a
ground reference near the trace edges can increase EMI: see Section 7.2.6.3, Ground Guidelines.
7.2.6.3
Ground Guidelines
7.2.6.3.1 PCB Outer Layers
Ideally the areas on the top and bottom layers of the PCB that are not enclosed by a shield should be
filled with ground after the routing is completed and connected with an adequate number of vias to the
ground on the inner ground planes.
7.2.6.3.2 Metallic Frames
ADVANCE INFORMATION
Ensure that all metallic parts are well connected to the PCB ground (like LCD screens metallic frames,
antennas reference planes, connector cages, flex cables grounds, and so forth). If using flex PCB ribbon
cables to bring high-frequency signals off the PCB, ensure they are adequately shielded (coaxial cables or
flex ribbons with a solid reference ground).
7.2.6.3.3 Connectors
For high-frequency signals going to connectors choose a fully shielded connector, if possible (for example,
SD card connectors). For signals going to external connectors or which are routed over long distances, it
is recommended to reduce their bandwidth by using low-pass filters (resistor, capacitor (RC) combinations
or lossy ferrite inductors). These filters will help to prevent emissions from the board and can also improve
the immunity from external disturbances.
7.2.6.3.4 Guard Ring on PCB Edges
The major advantage of a multilayer PCB with ground-plane is the ground return path below each and
every signal or power trace.
As shown in Figure 7-18 the field lines of the signal return to PCB ground as long as an infinite ground is
available.
Traces near the PCB-edges do not have this infinite ground and therefore may radiate more than the
others. Thus, signals (clocks) or power traces (core power) identified to be critical must not be routed in
the vicinity of PCB edges, or, if not avoidable, must be accompanied by a guard ring on the PCB edge.

Figure 7-19. Guard Ring Routing
The intention of the guard ring is that HF-energy, that otherwise would have been emitted from the PCB
edge, is reflected back into the board where it partially will be absorbed. For this purpose ground traces on
the borders of all layers (including power layer) must be applied as shown in Figure 7-19.
As these traces must have the same (HF–) potential as the ground plane they must be connected to the
ground plane at least every 10 mm.
For the optimum solution, the AGND and the DGND planes must be connected together at the power
supply source in a same point. This ensures that both planes are at the same potential, while the transfer
of noise from the digital to the analog domain is minimized.

Core Power Domains
This section provides boundary conditions and theoretical background to be applied as a guide for
optimizing a PCB design. The decoupling capacitor and PDN characteristics tables shown below give
recommended capacitors and PCB parameters to be followed for schematic and PCB designs. Board
designs that meet the static and dynamic PDN characteristics shown in tables below will be aligned to the
expected PDN performance needed to optimize SoC performance.

General Constraints and Theory

Max PCB static/DC voltage drop (IRd) budget can be relaxed to 7.5% of supply voltage when using
PMICs with remote sensing at the load as measured from PMIC’s power inductor and filter capacitor
node to Device’s supply input including any ground return losses. TI highly recommends remote
sensing.
Max PCB static/DC voltage drop (IRd) budget of 1.5% of supply voltage when using PMICs without
remote sensing as measured from PMIC’s power inductor and filter capacitor node to Processor input
including any ground return losses.
PMIC component DM and guidelines should be referenced for the following:
– Routing remote feedback sensing to optimize per each SMPS’s implementation
– Selecting power filtering capacitor values and PCB placement.
Max Effective Resistance (Reff) budget can range from 4 – 100mΩ for key Device power rails not
including ground returns depending upon maximum load currents and maximum DC voltage drop
budget (as discussed above).
Max Device supply input voltage difference budget of 5mV under max current loading shall be
maintained across all balls connected to a common power rail. This represents any voltage difference
that may exist between a remote sense point to any power input.
Max PCB Loop Inductance (LL) budget between Device’s power inputs and local bulk and high
frequency decoupling capacitors including ground returns should range from 0.4 – 2.5nH depending
upon maximum transient load currents.

Max PCB dynamic/AC peak-to-peak transient noise voltage budgets between PMIC and Device
including ground returns are as follows:
– +/-3% of nominal supply voltage for frequencies below the PMIC bandwidth (typ Fpmic ~
200kHz)
– +/-5% of nominal supply voltage for frequencies between Fpmic to Fpcb (typ 20 – 100MHz)
Max PCB Impedance (Z) vs Frequency (F) budget between Device’s power inputs and PMIC’s output
power filter node including ground return is determined by applying the Frequency Domain Target
Impedance Method to determine the PCB’s maximum frequency of interest (Fpcb). Ideally a properly
designed and decoupled PDN will exhibit smoothly increasing Z vs. F curve. There are 2 general
regions of interest as can be seen in Figure 7-20.
– 1st area is from DC (0Hz) up to Fpmic (typ a few 100 kHz) where a PMIC’s transient response
characteristic (i.e. Switching Freq, Compensation Loop BW) dominate. A PDN’s Z is typically very
low due to power filtering & bulk capacitor values when PDN has very low trace resistance (i.e.
good Reff performance). The goal is to maintain a smoothly increasing Z that is less than Zt1 over
this low frequency range. This will ensure that a max transient current event will not cause a
voltage drop more than the PMIC’s current step response can support (typ 3%).
– 2nd area is from Fpmic up to Fpcb (typ 20-100MHz) where a PCB’s inherent characteristics (i.e.
parasitic capacitance, planar spreading inductances) dominate. A PDN’s Z will naturally increase
with frequency. At frequencies between Fpmic up to Fpcb, the goal is to maintain a smoothly
increasing Z to be less than Zt2. This will ensue that the high frequency content of a max transient
current event will not cause a voltage drop to be more than 5% of the min supply voltage.

(2) Among the different capacitors, 470 nF is recommended (not required) to filter at 5-MHz to 10-MHz frequency range.
(3) In comparison with the EIA Class 1 dielectrics, Class 2 dielectric capacitors tend to have severe temperature drift, high dependence of
capacitance on applied voltage, high voltage coefficient of dissipation factor, high frequency coefficient of dissipation, and problems with
aging due to gradual change of crystal structure. Aging causes gradual exponential loss of capacitance and decrease of dissipation
factor.

Static PDN Analysis
One power net parameter derived from a PCB’s PDN static analysis is the Effective Resistance (Reff).
This is the total PCB power net routing resistance that is the sum of all the individual power net segments
used to deliver a supply voltage to the point of load and includes any series resistive elements (i.e. current
sensing resistor) that may be installed between the PMIC outputs and Processor inputs.
7.3.4
Dynamic PDN Analysis
Three power net parameters derived from a PCB’s PDN dynamic analysis are the Loop Inductance (LL),
Impedance (Z) and PCB Frequency of Interest (Fpcb).
• LL values shown are the recommended max PCB trace inductance between a decoupling capacitor’s
power supply and ground reference terminals when viewed from the decoupling capacitor with a
“theoretical shorted” applied across the Processor’s supply inputs to ground reference.
• Z values shown are the recommended max PCB trace impedances allowed between Fpmic up to Fpcb
frequency range that limits transient noise drops to no more than 5% of min supply voltage during max
transient current events.

reasonable number of decoupling capacitors no longer significantly reduces the power rail impedance
below the desired impedance target (Zt2). This is due to the dominance of the PCB’s parasitic planar

– Place PMIC for MPU domain as close as possible to the SoC
– Use capacitors with low inductance such as X7R & X7S Dielectric Dcap Components that are Auto qualified AEC-Q200, -55 to

– Place Power Segments on Signal Layers to Reduce Power Rail Loop Inductance. Consider additional PCB layers if needed.
– Use Through-Hole Via-In-Pad (thVIP) for Dcap power & Gnd pads outside SoC.

Power Supply Mapping
TPS65917 or TPS659039 are the Power Management ICs (PMICs) that should be used for the Device
designs. TI requires use of these PMICs for the following reasons:
• TI has validated their use with the Device
• Board level margins including transient response and output accuracy are analyzed and optimized for
the entire system
• Support for power sequencing requirements (refer to Section 5.10.3 Power Supply Sequences)
• Support for Adaptive Voltage Scaling (AVS) Class 0 requirements, including TI provided software
Whenever we allow for combining of rails mapped on any of the SMPSes, the PDN guidelines that are the
most stringent of the rails combined should be implemented for the particular supply rail.
ADVANCE INFORMATION
It is possible that some voltage domains on the device are unused in some systems. In such cases, to
ensure device reliability, it is still required that the supply pins for the specific voltage domains are
connected to some core power supply output.
These unused supplies though can be combined with any of the core supplies that are used (active) in the
system. e.g. if IVA and GPU domains are not used, they can be combined with the CORE domain,
thereby having a single power supply driving the combined CORE, IVA and GPU domains.
For the combined rail, the following relaxations do apply:
• The AVS voltage of active rail in the combined rail needs to be used to set the power supply
• The decoupling capacitance should be set according to the active rail in the combined rail

(1) Power consumption is highly application-specific. Separate analysis must be performed to ensure output current ratings (average and
peak) is within the limits of the PMIC for all rails of the device
(2) Dual phase (SMPS1/2) can be used as long as the peak power consumption is maintained below the SMPS1/2 capacity
a. For the latest rated output current specifications for the TPS659039 device, please refer to the PMIC data manual.
b. MPU power consumption is highly system dependent. A detailed power consumption estimate must be performed to confirm
compatibility. Example: Single vs Dual MPU, OPP_NOM vs OPP_OD vs OPP_HIGH, TPS659039 configured with VI≥3V vs VI<3V,
etc. Contact your TI representative for details.
(3) Combination 3 must only be used in systems where the MPU frequency is 1 GHz or lower. If greater than 1 GHz MPU is required, then
the vdd_mpu domain must be powered independently.

DPLL Voltage Requirement
The voltage input to the DPLLs has a low noise requirement. Board designs should supply these voltage
inputs with a low noise LDO to ensure they are isolated from any potential digital switching noise. The
TPS65917 and TPS659039 PMIC LDOLN outputs are specifically designed to meet this low noise
requirement.
NOTE
For more information about Input Voltage Sources, see Section 5.10.4.4 DPLLs, DLLs

Comparing loop inductances for capacitors at different distances from the processor’s input
power balls shows an 18% reduction for caps placed closer. This was derived by averaging
the inductances for the 3 caps with distances over 800mils (Avg LL = 1.33nH) vs the 3 caps
with distances less than 600mils (Avg LL = 1.096nH).

Line spacing:
– For a line width equal to W, the spacing between two lines must be 2W, at least. This minimizes the
crosstalk between switching signals between the different lines. On the PCB, this is not achievable
everywhere (for example, when breaking signals out from the device package), but it is
recommended to follow this rule as much as possible. When violating this guideline, minimize the
length of the traces running parallel to each other (see Figure 7-28).

Length matching (unless otherwise specified):
– For bus or traces at frequencies less than 10 MHz, the trace length matching (maximum length
difference between the longest and the shortest lines) must be less than 25 mm.
– For bus or traces at frequencies greater than 10 MHz, the trace length matching (maximum length
difference between the longest and the shortest lines) must be less than 2.5 mm.
Characteristic impedance
– Unless otherwise specified, the characteristic impedance for single-ended interfaces is
recommended to be between 35-Ω and 65-Ω.
Multiple peripheral support
– For interfaces where multiple peripherals have to be supported in the star topology, the length of
each branch has to be balanced. Before closing the PCB design, it is highly recommended to verify
signal integrity based on simulations including actual PCB extraction.
QSPI Board Design and Layout Guidelines
The following section details the routing guidelines that must be observed when routing the QSPI
interfaces.
• The qspi1_sclk output signal must be looped back into the qspi1_rtclk input.
• The signal propagation delay from the qspi1_sclk ball to the QSPI device CLK input pin (A to C) must
be approximately equal to the signal propagation delay from the QSPI device CLK pin to the
qspi1_rtclk ball (C to D).
• The signal propagation delay from the QSPI device CLK pin to the qspi1_rtclk ball (C to D) must be
approximately equal to the signal propagation delay of the control and data signals between the QSPI
device and the SoC device (E to F, or F to E).
• The signal propagation delay from the qspi1_sclk signal to the series terminators (R2 = 10 Ω) near the
QSPI device must be < 450pS (~7cm as stripline or ~8cm as microstrip)
• 50 Ω PCB routing is recommended along with series terminations, as shown in Figure 7-29.

Differential Interfaces
General Routing Guidelines
To maximize signal integrity, proper routing techniques for differential signals are important for high-speed
designs. The following general routing guidelines describe the routing guidelines for differential lanes and
differential signals.
• As much as possible, no other high-frequency signals must be routed in close proximity to the
differential pair.
• Must be routed as differential traces on the same layer. The trace width and spacing must be chosen
to yield the differential impedance value recommended.
• Minimize external components on differential lanes (like external ESD, probe points).
• Through-hole pins are not recommended.
• Differential lanes mustn’t cross image planes (ground planes).
• No sharp bend on differential lanes.

7.5.2
www.ti.com
Number of vias on the differential pairs must be minimized, and identical on each line of the differential
pair. In case of multiple differential lanes in the same interface, all lines should have the same number
of vias.
Shielded routing is to be promoted as much as possible (for instance, signals must be routed on
internal layers that are inside power and/or ground planes).
USB 2.0 Board Design and Layout Guidelines
This section discusses schematic guidelines when designing a universal serial bus (USB) system.
7.5.2.1
Background
Clock frequencies generate the main source of energy in a USB design. The USB differential DP/DM pairs
operate in high-speed mode at 480 Mbps. System clocks can operate at 12 MHz, 48 MHz, and 60 MHz.
The USB cable can behave as a monopole antenna; take care to prevent RF currents from coupling onto
the cable.
ADVANCE INFORMATION
When designing a USB board, the signals of most interest are:
• Device interface signals: Clocks and other signal/data lines that run between devices on the PCB.
• Power going into and out of the cable: The USB connector socket pin 1 (VBUS ) may be heavily
filtered and need only pass low frequency signals of less than ~100 KHz. The USB socket pin 4
(analog ground) must be able to return the current during data transmission, and must be filtered
sparingly.
• Differential twisted pair signals going out on cable, DP and DM: Depending upon the data transfer rate,
these device terminals can have signals with fundamental frequencies of 240 MHz (high speed), 6
MHz (full speed), and 750 kHz (low speed).
• External crystal circuit (device terminals XI and X0): 12 MHz, 19.2 MHz, 24 MHz, and 48 MHz
fundamental. When using an external crystal as a reference clock, a 24 MHz and higher crystal is

USB PHY Layout Guide
The following sections describe in detail the specific guidelines for USB PHY Layout.
7.5.2.2.1 General Routing and Placement
Use the following routing and placement guidelines when laying out a new design for the USB physical
layer (PHY). These guidelines help minimize signal quality and electromagnetic interference (EMI)
problems on a four-or-more layer evaluation module (EVM).
• Place the USB PHY and major components on the un-routed board first. For more details, see
Section 7.5.2.2.2.3.
• Route the high-speed clock and high-speed USB differential signals with minimum trace lengths.
• Route the high-speed USB signals on the plane closest to the ground plane, whenever possible.
• Route the high-speed USB signals using a minimum of vias and corners. This reduces signal
reflections and impedance changes.
• When it becomes necessary to turn 90°, use two 45° turns or an arc instead of making a single 90°
turn. This reduces reflections on the signal traces by minimizing impedance discontinuities.
• Do not route USB traces under or near crystals, oscillators, clock signal generators, switching
regulators, mounting holes, magnetic devices or IC’s that use or duplicate clock signals.
• Avoid stubs on the high-speed USB signals because they cause signal reflections. If a stub is
unavoidable, then the stub should be less than 200 mils.
• Route all high-speed USB signal traces over continuous planes (VCC or GND), with no interruptions.
Avoid crossing over anti-etch, commonly found with plane splits.

7.5.2.2.2 Specific Guidelines for USB PHY Layout
The following sections describe in detail the specific guidelines for USB PHY Layout.
7.5.2.2.2.1 Analog, PLL, and Digital Power Supply Filtering
To minimize EMI emissions, add decoupling capacitors with a ferrite bead at power supply terminals for
the analog, phase-locked loop (PLL), and digital portions of the chip. Place this array as close to the chip
as possible to minimize the inductance of the line and noise contributions to the system. An analog and
digital supply example is shown in Figure 7-30. In case of multiple power supply pins with the same
function, tie them up to a single low-impedance point in the board and then add the decoupling capacitors,
in addition to the ferrite bead. This array of caps and ferrite bead improve EMI and jitter performance.
Take both EMI and jitter into account before altering the configuration.

Consider the recommendations listed below to achieve proper ESD/EMI performance:
• Use a 0.01 μF cap on each cable power VBUS line to chassis GND close to the USB connector pin.
• Use a 0.01 μF cap on each cable ground line to chassis GND next to the USB connector pin.
• If voltage regulators are used, place a 0.01 μF cap on both input and output. This is to increase the
immunity to ESD and reduce EMI. For other requirements, see the device-specific datasheet.
7.5.2.2.2.2 Analog, Digital, and PLL Partitioning
If separate power planes are used, they must be tied together at one point through a low-impedance
bridge or preferably through a ferrite bead. Care must be taken to capacitively decouple each power rail
close to the device. The analog ground, digital ground, and PLL ground must be tied together to the lowimpedance circuit board ground plane.
7.5.2.2.2.3 Board Stackup
Because of the high frequencies associated with the USB, a printed circuit board with at least four layers
is recommended; two signal layers separated by a ground and power layer as shown in Figure 7-31.
ADVANCE INFORMATION
Signal 1
GND Plane
Power Plane
Signal 2
Figure 7-31. Four-Layer Board Stack-Up
The majority of signal traces should run on a single layer, preferably SIGNAL1. Immediately next to this
layer should be the GND plane, which is solid with no cuts. Avoid running signal traces across a split in
the ground or power plane. When running across split planes is unavoidable, sufficient decoupling must
be used. Minimizing the number of signal vias reduces EMI by reducing inductance at high frequencies.
7.5.2.2.2.4 Cable Connector Socket
Short the cable connector sockets directly to a small chassis ground plane (GND strap) that exists
immediately underneath the connector sockets. This shorts EMI (and ESD) directly to the chassis ground
before it gets onto the USB cable. This etch plane should be as large as possible, but all the conductors
coming off connector pins 1 through 6 must have the board signal GND plane run under. If needed, scoop
out the chassis GND strap etch to allow for the signal ground to extend under the connector pins. Note
that the etches coming from pins 1 and 4 (VBUS power and GND) should be wide and via-ed to their
respective planes as soon as possible, respecting the filtering that may be in place between the connector
pin and the plane. See Figure 7-32 for a schematic example.
Place a ferrite in series with the cable shield pins near the USB connector socket to keep EMI from getting
onto the cable shield. The ferrite bead between the cable shield and ground may be valued between 10 Ω
and 50 Ω at 100 MHz; it should be resistive to approximately 1 GHz. To keep EMI from getting onto the
cable bus power wire (a very large antenna) a ferrite may be placed in series with cable bus power,
VBUS, near the USB connector pin 1. The ferrite bead between connector pin 1 and bus power may be
valued between 47 Ω and approximately 1000 Ω at 100 MHz. It should continue being resistive out to
approximately 1 GHz, as shown in Figure 7-32.

7.5.2.2.2.5 Clock Routings
To address the system clock emissions between devices, place a ~10 to 130 Ω resistor in series with the
clock signal. Use a trial and error method of looking at the shape of the clock waveform on a high-speed
oscilloscope and of tuning the value of the resistance to minimize waveform distortion. The value on this
resistor should be as small as possible to get the desired effect. Place the resistor close to the device
generating the clock signal. If an external crystal is used, follow the guidelines detailed in the Selection
and Specification of Crystals for Texas Instruments USB 2.0 Devices (SLLA122).
When routing the clock traces from one device to another, try to use the 3W spacing rule. The distance
from the center of the clock trace to the center of any adjacent signal trace should be at least three times
the width of the clock trace. Many clocks, including slow frequency clocks, can have fast rise and fall
times. Using the 3W rule cuts down on crosstalk between traces. In general, leave space between each of
the traces running parallel between the devices. Avoid using right angles when routing traces to minimize
the routing distance and impedance discontinuities. For further protection from crosstalk, run guard traces
beside the clock signals (GND pin to GND pin), if possible. This lessens clock signal coupling, as shown in
Figure 7-33.

7.5.2.2.2.6 Crystals/Oscillator
Keep the crystal and its load capacitors close to the USB PHY pins, XI and XO (see Figure 7-34). Note
that frequencies from power sources or large capacitors can cause modulations within the clock and
should not be placed near the crystal. In these instances, errors such as dropped packets occur. A
placeholder for a resistor, in parallel with the crystal, can be incorporated in the design to assist oscillator
startup.
Power is proportional to the current squared. The current is I = C*dv/dt, because dv/dt is a function of the
PHY, current is proportional to the capacitive load. Cutting the load to 1/2 decreases the current by 1/2
and the power to 1/4 of the original value. For more details on crystal selection, see the Selection and
Specification of Crystals for Texas Instruments USB 2.0 Devices (SLLA122).

7.5.2.2.2.7 DP/DM Trace
Place the USB PHY as close as possible to the USB 2.0 connector. The signal swing during high-speed
operation on the DP/DM lines is relatively small (400 mV ± 10%), so any differential noise picked up on
the twisted pair can affect the received signal. When the DP/DM traces do not have any shielding, the
traces tend to behave like an antenna and picks up noise generated by the surrounding components in
the environment. To minimize the effect of this behavior:
• DP/DM traces should always be matched lengths and must be no more than 4 inches in length;
otherwise, the eye opening may be degraded (see Figure 7-35).
• Route DP/DM traces close together for noise rejection on differential signals, parallel to each other and
within two mils in length of each other. The measurement for trace length must be started from
device's balls.
• A high-speed USB connection is made through a shielded, twisted pair cable with a differential
characteristic impedance of 90 Ω ±15%. In layout, the impedance of DP and DM should each be 45 Ω
± 10%.
• DP/DM traces should not have any extra components to maintain signal integrity. For example, traces
cannot be routed to two USB connectors.

7.5.2.2.2.8 DP/DM Vias
When a via must be used, increase the clearance size around it to minimize its capacitance. Each via
introduces discontinuities in the signal’s transmission line and increases the chance of picking up
interference from the other layers of the board. Be careful when designing test points on twisted pair lines;
through-hole pins are not recommended.
7.5.2.2.2.9 Image Planes
An image plane is a layer of copper (voltage plane or ground plane), physically adjacent to a signal routing
plane. Use of image planes provides a low impedance, shortest possible return path for RF currents. For a
USB board, the best image plane is the ground plane because it can be used for both analog and digital
circuits.
• Do not route traces so they cross from one plane to the other. This can cause a broken RF return path
resulting in an EMI radiating loop as shown in Figure 7-36. This is important for higher frequency or
repetitive signals. Therefore, on a multi-layer board, it is best to run all clock signals on the signal
plane above a solid ground plane.
• Avoid crossing the image power or ground plane boundaries with high-speed clock signal traces
immediately above or below the separated planes. This also holds true for the twisted pair signals (DP,
DM). Any unused area of the top and bottom signal layers of the PCB can be filled with copper that is
connected to the ground plane through vias.

7.5.2.2.2.10 JTAG Interface
For test and debug of the USB PHY only, an IEEE Standard 1149.1-1990, IEEE Standard Test Access
Port and Boundary-Scan Architecture (JTAG) and Serial Test and Configuration Interface (STCI) may be
available on the System-on-Chip (SoC). If available, keep the USB PHY JTAG interface less than six
inches; keeping this distance short reduces noise coupling from other devices and signal loss due to
resistance.
7.5.2.2.2.11 Power Regulators
Switching power regulators are a source of noise and can cause noise coupling if placed close to sensitive
areas on a circuit board. Therefore, the switching power regulator should be kept away from the DP/DM
signals, the external clock crystal (or clock oscillator), and the USB PHY.
7.5.2.3
Electrostatic Discharge (ESD)
International Electronic Commission (IEC) 61000-4-xx is a set of about 25 testing specifications from the
IEC. IEC ESD Stressing is done both un-powered and with power applied, and with the device functioning.
There must be no physical damage, and the device must keep working normally after the conclusion of
the stressing. Typically, equipment has to pass IEC stressing at 8 kV contact and 15 kV air discharge, or
higher. To market products/systems in the European community, all products/systems must be CE
compliant and have the CE Mark. To obtain the CE Mark, all products/systems need to go through and
pass IEC standard requirements; for ESD, it is 61000-4-2. 61000-4-2 requires that the products/systems
pass contact discharge at 8 kV and air discharge at 15 kV. When performing an IEC ESD Stressing, only
pins accessible to the outside world need to pass the test. The system into which the integrated circuit (IC)
is placed makes a difference in how well the IC does. For example:
• Cable between the zap point and the IC attenuate the high frequencies in the waveform.
• Series inductance on the PCB board attenuates the high frequencies.
• Unless the capacitor’s ground connection is inductive, capacitance to ground shunts away high
frequencies.
7.5.2.3.1 IEC ESD Stressing Test
The following sections describe in detail the IEC ESD Stressing Test modes and test types.
7.5.2.3.1.1 Test Mode
The IEC ESD Stressing test is done through two modes: contact discharge mode and air discharge mode.

For the contact discharge test mode, the preferred way is direct contact applied to the conductive surfaces
of the equipment under test (EUT). In the case of the USB system, the conductive surface is the outer
casing of the USB connector. The electrode of the ESD generator is held in contact with the EUT or a
coupling plane prior to discharge. The arc formation is created under controlled conditions, inside a relay,
resulting in repeatable waveforms; however, this arc does not accurately recreate the characteristic unique
to the arc of an actual ESD event.
7.5.2.3.1.2 Air Discharge Mode
The air discharge usually applies to a non-conductive surface of the EUT. Instead of a direct contact with
the EUT, the charged electrode of the ESD generator is brought close to the EUT, and a spark in the air to
the EUT actuates the discharge. Compared to the contact discharge mode, the air discharge is more
realistic to the actual ESD occurrence. However, due to the variations of the arc length, it may not be able
to produce repeatable waveform.
7.5.2.3.1.3 Test Type
ADVANCE INFORMATION
The IEC ESD Stressing test has two test types: direct discharge and indirect discharge. Direct discharge
is applies directly to the surface or the structure of the EUT. It includes both contact discharge and air
discharge modes. Indirect discharge applies to a coupling plane in the vicinity of the EUT. The indirect
discharge is used to simulate personal discharge to objects which are adjacent to the EUT. It includes
contact discharge mode only.
7.5.2.3.2 TI Component Level IEC ESD Test
TI Component Level IEC ESD Test tests only the IC terminals that are exposed in system level
applications. It can be used to determine the robustness of on-chip protection and the latch-up immunity.
The IC can only pass the TI Component Level IEC ESD test when there is no latch-up and IC is fully
functional after the test.
7.5.2.3.3 Construction of a Custom USB Connector
A standard USB connector, either type A or type B, provides good ESD protection. However, if a custom
USB connector is desired, the following guidelines should be observed to ensure good ESD protection.
• There should be an easily accessible shield plate next to the connector for air-discharge mode
purpose.
• Tie the outer shield of the connector to GND. When a cable is inserted into the connector, the shield of
the cable should first make contact with the outer shield.
• If the connector includes power and GND, the lead of power and GND need to be longer than the
leads of signal.
• The connector needs to have a key to ensure proper insertion of the cable.
• See the standard USB connector for reference.

are additional considerations for ESD protection in a system.
• Metallic shielding for both ESD and EMI
• Chassis GND isolation from the board GND
• Air gap designed on board to absorb ESD energy
• Clamping diodes to absorb ESD energy
• Capacitors to divert ESD energy
• The use of external ESD components on the DP/DM lines may affect signal quality and are not

This section provides the timing specification for the USB3.0 (USB1 in the device) interface as a PCB

signal integrity, cross-talk, and signal timing. TI has performed the simulation and system design work to
ensure the USB3.0 interface requirements are met. The design rules stated within this document are
targeted at DEVICE mode electrical compliance. HOST mode and/or systems that do not include the 3m
USB cable and far-end 11-inch PCB trace required by DEVICE mode compliance testing may not need
the complete list of optimizations shown in this document; however, applying these optimizations to HOST
mode systems will lead to optimal DEVICE mode performance.

• Minimize the via usage and layer transition
• Keep large spacing between TX and RX pairs.
• Intra-lane delay mismatch between DP and DM less than 1ps. Same for RXp and RXn.
• Distance between common mode filter (CMF) and ESD protection device should be as short as
possible
• Distance between ESD protection device and USB connector should be as short as possible.
• Distance between AC capacitors (TX only) and CMF should be as short as possible.
• USB 3.0 signals should always be routed over an adjacent ground plane.

The TMDS signals are high speed differential pairs. Care must be taken in the PCB layout of these signals
to ensure good signal integrity.
The TMDS differential signal traces must be routed to achieve 100 Ω (+/- 10%) differential impedance and
60 Ω (+/-10%) single ended impedance. Single ended impedance control is required because differential
signals can’t be closely coupled on PCBs and therefore single ended impedance becomes important.
These impedances are impacted by trace width, trace spacing, distance to reference planes, and dielectric
material. Verify with a PCB design tool that the trace geometry for both data signal pairs results in as
close to 60 Ω impedance traces as possible. For best accuracy, work with your PCB fabricator to ensure
this impedance is met.
In general, closely coupled differential signal traces are not an advantage on PCBs. When differential
signals are closely coupled, tight spacing and width control is necessary. Very small width and spacing
variations affect impedance dramatically, so tight impedance control can be more problematic to maintain
in production.
ADVANCE INFORMATION
Loosely coupled PCB differential signals make impedance control much easier. Wider traces and spacing
make obstacle avoidance easier, and trace width variations don’t affect impedance as much, therefore it’s
easier to maintain accurate impedance over the length of the signal. The wider traces also show reduced
skin effect and therefore often result in better signal integrity.
Some general routing guidelines regarding TMDS:
• Avoid crossing splits reference plane(s).
• Shorter trace length is preferred.
• Distance between common mode filter (CMF) and ESD protection device should be as short as
possible
• Distance between ESD protection device and HDMI connector should be as short as possible.

TPD5S115
The TPD5S115 is an integrated HDMI companion chip solution. The device provides a regulated 5 V
output (5VOUT) for sourcing the HDMI power line. The TPD5S115 exceeds the IEC61000-4-2 (Level 4)
ESD protection level.
7.5.4.4
HDMI ESD Protection Device (Required)
Interfaces that connect to a cable such as HDMI generally require more ESD protection than can be built
into the processor’s outputs. Therefore this HDMI interface requires the use of an ESD protection chip to
provide adequate ESD.
When selecting an ESD protection chip, choose the lowest capacitance ESD protection available to
minimize signal degradation. In no case should be ESD protection circuit capacitance be more than 5pF.
TI manufactures these devices that provide ESD protection for HDMI signals such as the TPDxE05U06.

7.5.6.2.2 Routing Specifications
7.5.6.2.2.1 Impedance
The PCIe data signal traces must be routed to achieve 100-Ω (±10%) differential impedance and 60-Ω
(±10%) single-ended impedance. The single-ended impedance is required because differential signals are
extremely difficult to closely couple on PCBs and, therefore, single-ended impedance becomes important.
These requirements are the same as those recommended in the PCIe Motherboard Checklist 1.0
document, available from PCI-SIG (www.pcisig.com).
These impedances are impacted by trace width, trace spacing, distance between signals and referencing
planes, and dielectric material. Verify with a PCB design tool that the trace geometry for both data signal
pairs result in as close to 100-Ω differential impedance and 60-Ω single-ended impedance as possible. For
best accuracy, work with your PCB fabricator to ensure this impedance is met. See Table 7-26 below.
In general, closely coupled differential signal traces are not an advantage on PCBs. When differential
signals are closely coupled, tight spacing and width control is necessary. Very small width and spacing
variations affect impedance dramatically, so tight impedance control can be more problematic to maintain
in production. For PCBs with very tight space limitations (which are usually small) this can work, but for
most PCBs, the loosely coupled option is probably best.
Loosely coupled PCB differential signals make impedance control much easier. Wider traces and spacing
make obstacle avoidance easier (because each trace is not so fixed in position relative to the other), and
trace width variations don’t affect impedance as much, therefore it’s easier to maintain an accurate
impedance over the length of the signal. For longer routes, the wider traces also show reduced skin effect
and therefore often result in better signal integrity with a larger eye diagram opening.

LJCB_REFN/P Connections
A Common Refclk Rx Architecture is required to be used for the device PCIe interface. Specifically, two
modes of Common Refclk Rx Architecture are supported:
• External REFCLK Mode: An common external 100MHz clock source is distributed to both the Device
and the link partner
• Output REFCLK Mode: A 100MHz HCSL clock source is output by the device and used by the link
partner
ADVANCE INFORMATION
In External REFCLK Mode, a high-quality, low-jitter, differential HCSL 100MHz clock source compliant to
the PCIe REFCLK AC Specifications should be provided on the Device’s ljcb_clkn / ljcb_clkp inputs.
Alternatively, an LVDS clock source can be used with the following additional requirements:
• External AC coupling capacitors described in Table 7-28 should be populated at the ljcb_clkn /
ljcb_clkp inputs.
• All termination requirements (ex. parallel 100 Ω termination) from the clock source manufacturer should
be followed.
In Output REFCLK Mode, the 100MHz clock from the Device’s DPLL_PCIE_REF should be output on
the Device’s ljcb_clkn / ljcb_clkp pins and used as the HCSL REFCLK by the link partner. External nearside termination to ground described in Table 7-29 is required on both of the ljcb_clkn / ljcb_clkp outputs
in this mode.

CSI2_0 and CSI2_1 MIPI CSI-2 (1.5 Gbps)
The general guidelines for the PCB differential lines are:
• Differential trace impedance Z0 = 100 Ω (minimum = 85 Ω, maximum = 115 Ω)
• Total conductor length from the Device package pins to the peripheral device package pins is 25 to 30
cm with common FR4 PCB and flex materials.
NOTE
Longer interconnect length can be supported at the expense of detailed simulations of the
complete link including driver and receiver models.
The general rule of thumb for the space S = 2 × W is not designated (see Figure 7-28, Guard Illustration).
It is because although the S = 2 × W rule is a good rule of thumb, it is not always the best solution. The
electrical performance will be checked with the frequency-domain specification. Even though the designer
does not follow the S = 2 × W rule, the differential lines are ok if the lines satisfy the frequency-domain
specification.
Because the MIPI signals are used for low-power, single-ended signaling in addition to their high-speed
differential implementation, the pairs must be loosely coupled.

Maxwell Equation Solver such as the high-frequency structure simulator (HFSS) or equivalent, and
compared to the frequency-domain specification as defined in the section 7 of the MIPI Alliance
Specification for D-PHY Version v1-01-00_r0-03.
If the PCB lines satisfy the frequency-domain specification, the design is finished. Otherwise, the design
needs to be improved.

When not using all or part of a DDR2 interface, the proper method of handling the unused pins is to tie off
the ddrx_dqsi pins to ground via a 1k-Ω resistor and to tie off the ddrx_dqsni pins to the corresponding
vdds_ddrx supply via a 1k-Ω resistor. This needs to be done for each byte not used. The vdds_ddrx and
ddrx_vref0 power supply pins need to be connected to their respective power supplies even if DDRx is not
being used. All other DDR interface pins can be left unconnected. Note that the supported modes for use
of the DDR EMIF are 32-bits wide, 16-bits wide, or not used.

(1) Ground reference layers are preferred over power reference layers. Be sure to include bypass caps to accommodate reference layer
return current as the trace routes switch routing layers. A full ground reference layer should be placed adjacent to each DDR routing
layer in PCB stack up.
(2) No traces should cross reference plane cuts within the DDR routing region. High-speed signal traces crossing reference plane cuts
create large return current paths which can lead to excessive crosstalk and EMI radiation.
(3) Reference planes are to be directly adjacent to the signal plane to minimize the size of the return current loop.
(4) An 18-mil pad assumes Via Channel is the most economical BGA escape. A 20-mil pad may be used if additional layers are available
for power routing. An 18-mil pad is required for minimum layer count escape.

The region shown in Table 7-36 should encompass all the DDR2 circuitry and varies depending on
placement. Non-DDR2 signals should not be routed on the DDR signal layers within the DDR2 keepout
region. Non-DDR2 signals may be routed in the region, provided they are routed on layers separated from
DDR2 signal layers by a ground layer. No breaks should be allowed in the reference ground layers in this
region. In addition, the vdds_ddrx power plane should cover the entire keepout region. Routes for the two
DDR interfaces must be separated by at least 4x; the more separation, the better.

High-speed (HS) bypass capacitors are critical for proper DDR2 interface operation. It is particularly
important to minimize the parasitic series inductance of the HS bypass capacitors, processor/DDR power,
and processor/DDR ground connections. Table 7-38 contains the specification for the HS bypass
capacitors as well as for the power connections on the PCB. Generally speaking, it is good to:
1. Fit as many HS bypass capacitors as possible.
2. HS bypass capacitor value is < 1µF
3. Minimize the distance from the bypass cap to the pins/balls being bypassed.
4. Use the smallest physical sized capacitors possible with the highest capacitance readily available.
5. Connect the bypass capacitor pads to their vias using the widest traces possible and using the largest
hole size via possible.
6. Minimize via sharing. Note the limites on via sharing shown in Table 7-38.

DDR3 Interface Schematic
7.6.3.4.1 32-Bit DDR3 Interface
The DDR3 interface schematic varies, depending upon the width of the DDR3 devices used and the width
of the bus used (16 or 32 bits). General connectivity is straightforward and very similar. 16-bit DDR
devices look like two 8-bit devices. Figure 7-55 and Figure 7-56 show the schematic connections for 32-bit
interfaces using x16 devices.
7.6.3.4.2 16-Bit DDR3 Interface
When not using all or part of a DDR interface, the proper method of handling the unused pins is to tie off
the ddrx_dqsi pins to ground via a 1k-Ω resistor and to tie off the ddrx_dqsni pins to the corresponding
vdds_ddrx supply via a 1k-Ω resistor. This needs to be done for each byte not used. Although these
signals have internal pullups and pulldowns, external pullups and pulldowns provide additional protection
against external electrical noise causing activity on the signals.
The vdds_ddrx and ddrx_vref0 power supply pins need to be connected to their respective power supplies
even if ddrx is not being used. All other DDR interface pins can be left unconnected. Note that the
supported modes for use of the DDR EMIF are 32-bits wide, 16-bits wide, or not used.

(1) Ground reference layers are preferred over power reference layers. Be sure to include bypass caps to accommodate reference layer
return current as the trace routes switch routing layers.
(2) No traces should cross reference plane cuts within the DDR routing region. High-speed signal traces crossing reference plane cuts
create large return current paths which can lead to excessive crosstalk and EMI radiation.
(4) An 18-mil pad assumes Via Channel is the most economical BGA escape. A 20-mil pad may be used if additional layers are available
for power routing. An 18-mil pad is required for minimum layer count escape.
(5) Z is the nominal singled-ended impedance selected for the PCB specified by PS9.

Placement
Figure 7-57 shows the required placement for the processor as well as the DDR3 devices. The
dimensions for this figure are defined in Table 7-49. The placement does not restrict the side of the PCB
on which the devices are mounted. The ultimate purpose of the placement is to limit the maximum trace
lengths and allow for proper routing space. For a 16-bit DDR memory system, the high-word DDR3
devices are omitted from the placement.

DDR3 Keepout Region
ADVANCE INFORMATION
The region of the PCB used for DDR3 circuitry must be isolated from other signals. The DDR3 keepout
region is defined for this purpose and is shown in Figure 7-58. The size of this region varies with the
placement and DDR routing. Additional clearances required for the keepout region are shown in Table 749. Non-DDR3 signals should not be routed on the DDR signal layers within the DDR3 keepout region.
Non-DDR3 signals may be routed in the region, provided they are routed on layers separated from the
DDR signal layers by a ground layer. No breaks should be allowed in the reference ground layers in this
region. In addition, the 1.5-V DDR3 power plane should cover the entire keepout region. Also note that the
two signals from the DDR3 controller should be separated from each other by the specification in Table 749 (see KOD37).

Bulk Bypass Capacitors
Bulk bypass capacitors are required for moderate speed bypassing of the DDR3 and other circuitry.
Table 7-50 contains the minimum numbers and capacitance required for the bulk bypass capacitors. Note

(1) These devices should be placed near the devices they are bypassing, but preference should be given to the placement of the highspeed (HS) bypass capacitors and DDR3 signal routing.
High-speed (HS) bypass capacitors are critcal for proper DDR3 interface operation. It is particularly
important to minimize the parasitic series inductance of the HS bypass capacitors, processor/DDR power,
and processor/DDR ground connections. Table 7-51 contains the specification for the HS bypass
capacitors as well as for the power connections on the PCB. Generally speaking, it is good to:
1. Fit as many HS bypass capacitors as possible.
2. Minimize the distance from the bypass cap to the pins/balls being bypassed.
3. Use the smallest physical sized capacitors possible with the highest capacitance readily available.
4. Connect the bypass capacitor pads to their vias using the widest traces possible and using the largest
hole size via possible.
5. Minimize via sharing. Note the limites on via sharing shown in Table 7-51.

(9) An HS bypass capacitor may share a via with a DDR device mounted on the same side of the PCB. A wide trace should be used for the
connection and the length from the capacitor pad to the DDR device pad should be less than 150 mils.
(10) Up to a total of two pairs of DDR power/ground balls may share a via.
(11) The capacitor recommendations in this data manual reflect only the needs of this processor. Please see the memory vendor’s
guidelines for determining the appropriate decoupling capacitor arrangement for the memory device itself.
(12) For more information, see Section 7.3, Core Power Domains.
7.6.3.10.1 Return Current Bypass Capacitors
Use additional bypass capacitors if the return current reference plane changes due to DDR3 signals
hopping from one signal layer to another. The bypass capacitor here provides a path for the return current
to hop planes along with the signal. As many of these return current bypass capacitors should be used as
possible. Because these are returns for signal current, the signal via size may be used for these
capacitors.
7.6.3.11 Net Classes
Table 7-52 lists the clock net classes for the DDR3 interface. Table 7-53 lists the signal net classes, and

7.6.3.12 DDR3 Signal Termination
Signal terminators are required for the CK and ADDR_CTRL net classes. The data lines are terminated by
ODT and, thus, the PCB traces should be unterminated. Detailed termination specifications are covered in
the routing rules in the following sections.
7.6.3.13 VREF_DDR Routing
ddrx_vref0 (VREF) is used as a reference by the input buffers of the DDR3 memories as well as the
processor. VREF is intended to be half the DDR3 power supply voltage and is typically generated with the
DDR3 VDDS and VTT power supply. It should be routed as a nominal 20-mil wide trace with 0.1 µF
bypass capacitors near each device connection. Narrowing of VREF is allowed to accommodate routing
congestion.

7.6.3.14 VTT
Like VREF, the nominal value of the VTT supply is half the DDR3 supply voltage. Unlike VREF, VTT is
expected to source and sink current, specifically the termination current for the ADDR_CTRL net class
Thevinen terminators. VTT is needed at the end of the address bus and it should be routed as a power
sub-plane. VTT should be bypassed near the terminator resistors.
7.6.3.15 CK and ADDR_CTRL Topologies and Routing Definition
The CK and ADDR_CTRL net classes are routed similarly and are length matched to minimize skew
between them. CK is a bit more complicated because it runs at a higher transition rate and is differential.
The following subsections show the topology and routing for various DDR3 configurations for CK and
ADDR_CTRL. The figures in the following subsections define the terms for the routing specification
detailed in Table 7-54.

7.6.3.16 Data Topologies and Routing Definition
No matter the number of DDR3 devices used, the data line topology is always point to point, so its
definition is simple.
Care should be taken to minimize layer transitions during routing. If a layer transition is necessary, it is
better to transition to a layer using the same reference plane. If this cannot be accommodated, ensure
there are nearby ground vias to allow the return currents to transition between reference planes if both
reference planes are ground or vdds_ddr. Ensure there are nearby bypass capacitors to allow the return
currents to transition between reference planes if one of the reference planes is ground. The goal is to
minimize the size of the return current loops.
7.6.3.16.1 DQS and DQ/DM Topologies, Any Number of Allowed DDR3 Devices

7.6.3.17 Routing Specification
7.6.3.17.1 CK and ADDR_CTRL Routing Specification
Skew within the CK and ADDR_CTRL net classes directly reduces setup and hold margin and, thus, this
skew must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter
traces up to the length of the longest net in the net class and its associated clock. A metric to establish
this maximum length is Manhattan distance. The Manhattan distance between two points on a PCB is the
length between the points when connecting them only with horizontal or vertical segments. A reasonable
trace route length is to within a percentage of its Manhattan distance. CACLM is defined as Clock Address
Control Longest Manhattan distance.

Given the clock and address pin locations on the processor and the DDR3 memories, the maximum
possible Manhattan distance can be determined given the placement. Figure 7-79 and Figure 7-80 show
this distance for four loads and two loads, respectively. It is from this distance that the specifications on
the lengths of the transmission lines for the address bus are determined. CACLM is determined similarly
for other address bus configurations; that is, it is based on the longest net of the CK/ADDR_CTRL net
class. For CK and ADDR_CTRL routing, these specifications are contained in Table 7-54.

It is very likely that the longest CK/ADDR_CTRL Manhattan distance will be for Address Input 8 (A8) on the DDR3
memories. CACLM is based on the longest Manhattan distance due to the device placement. Verify the net class that
satisfies this criteria and use as the baseline for CK/ADDR_CTRL skew matching and length control.
The length of shorter CK/ADDR_CTRL stubs as well as the length of the terminator stub are not included in this
length calculation. Non-included lengths are grayed out in the figure.
Assuming A8 is the longest, CALM = CACLMY + CACLMX + 300 mils.
The extra 300 mils allows for routing down lower than the DDR3 memories and returning up to reach A8.

(1) Max value is based upon conservative signal integrity approach. This value could be extended only if detailed signal integrity analysis of
rise time and fall time confirms desired operation.
(2) The use of vias should be minimized.
(3) Additional bypass capacitors are required when using the DDR_1V5 plane as the reference plane to allow the return current to jump
between the DDR_1V5 plane and the ground plane when the net class switches layers at a via.
(4) Non-mirrored configuration (all DDR3 memories on same side of PCB).
(5) Mirrored configuration (one DDR3 device on top of the board and one DDR3 device on the bottom).
(6) While this length can be increased for convenience, its length should be minimized.
(7) ADDR_CTRL net class only (not CK net class). Minimizing this skew is recommended, but not required.
(8) CK net class only.
(10) The ADDR_CTRL net class of the other DDR EMIF is considered other DDR3 trace spacing.
(11) CK spacing set to ensure proper differential impedance.
(12) The most important thing to do is control the impedance so inadvertent impedance mismatches are not created. Generally speaking,
center-to-center spacing should be either 2w or slightly larger than 2w to achieve a differential impedance equal to twice the singleended
impedance, Zo.
(13) Source termination (series resistor at driver) is specifically not allowed.
(14) Termination values should be uniform across the net class.
(15) Via count difference may increase by 1 only if accurate 3-D modeling of the signal flight times – including accurately modeled signal
propagation through vias – has been applied to ensure all segment skew maximums are not exceeded.
7.6.3.17.2 DQS and DQ Routing Specification
Skew within the DQS and DQ/DM net classes directly reduces setup and hold margin and thus this skew
must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter traces
up to the length of the longest net in the net class and its associated clock. As with CK and ADDR_CTRL,
a reasonable trace route length is to within a percentage of its Manhattan distance. DQLMn is defined as
DQ Longest Manhattan distance n, where n is the byte number. For a 32-bit interface, there are four
DQLMs, DQLM0-DQLM3. Likewise, for a 16-bit interface, there are two DQLMs, DQLM0-DQLM1.
NOTE
It is not required, nor is it recommended, to match the lengths across all bytes. Length
matching is only required within each byte.
Given the DQS and DQ/DM pin locations on the processor and the DDR3 memories, the maximum
possible Manhattan distance can be determined given the placement. Figure 7-81 shows this distance for
four loads. It is from this distance that the specifications on the lengths of the transmission lines for the
data bus are determined. For DQS and DQ/DM routing, these specifications are contained in Table 7-55.

8 Device and Documentation Support
TI offers an extensive line of development tools, including methods to evaluate the performance of the
processors, generate code, develop algorithm implementations, and fully integrate and debug software
and hardware modules as listed below.
8.1
Device Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
microprocessors (MPUs) and support tools. Each device has one of three prefixes: X, P, or null (no prefix)
(for example, DRA77xP). Texas Instruments recommends two of three possible prefix designators for its
support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development
from engineering prototypes (TMDX) through fully qualified production devices and tools (TMDS).
X
Experimental device that is not necessarily representative of the final device's electrical
specifications and may not use production assembly flow.
P
Prototype device that is not necessarily the final silicon die and may not necessarily meet
final electrical specifications.
null
Production version of the silicon die that is fully qualified.
Support tool development evolutionary flow:
TMDX
Development-support product that has not yet completed Texas Instruments internal
qualification testing.
TMDS
Fully-qualified development-support product.
X and P devices and TMDX development-support tools are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
Production devices and TMDS development-support tools have been characterized fully, and the quality
and reliability of the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (X or P) have a greater failure rate than the standard production
devices. Texas Instruments recommends that these devices not be used in any production system
because their expected end-use failure rate still is undefined. Only qualified production devices are to be
used.
For orderable part numbers of DRA77xP devices in the ACD package type, see the Package Option
Addendum of this document, the TI website (www.ti.com), or contact your TI sales representative.
For additional description of the device nomenclature markings on the die, see the Silicon Errata (literature
number SPRZ398).

Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

IMPORTANT NOTICE
Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its
semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers
should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated
circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and
services.
Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or
endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards
and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must
ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in
life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.
Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life
support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all
medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.
TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).
Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications
and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory
requirements in connection with such selection.
Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s noncompliance with the terms and provisions of this Notice.
