SPRS681A – OCTOBER 2010 – REVISED MARCH 2011
Description
The AM389x Sitara™ ARM® MPUs are a highly-integrated, programmable platform that leverages TI's
Sitara™ technology to meet the processing needs of the following applications: Single-Board Computing,
Network and Communications Processing, Industrial Automation, Human Machine Interface, and
Interactive Point-of-Service Kiosks.
The device enables OEMs and ODMs to quickly bring to market devices featuring robust operating
systems support, rich user interfaces, and high processing performance through the maximum flexibility of
a fully integrated mixed processor solution. The device combines high-performance ARM® processing with
a highly-integrated peripheral set.
The rich peripheral set provides the ability to control external peripheral devices and communicate with
external processors. For details on each of the peripherals, see the related sections in this document and
the associated peripheral reference guides. The peripheral set includes: HD Video Processing Subsystem
(HDVPSS), which provides output of simultaneous HD and SD analog video and dual HD video inputs; up
to two Gigabit Ethernet MACs (10/100/1000 Mbps) with GMII and MDIO interface; two USB ports with
integrated 2.0 PHY; PCIe® port x2 lanes GEN2 compliant interface, which allows the device to act as a
PCIe® root complex or device endpoint; one 6-channel McASP audio serial port (with DIT mode); two
dual-channel McASP audio serial ports (with DIT mode); one McBSP multichannel buffered serial port;
three UARTs with IrDA and CIR support; SPI serial interface; SD/SDIO serial interface; two I2C
master/slave interfaces; up to 64 General-Purpose I/O (GPIO); seven 32-bit timers; system watchdog
timer; dual DDR2/3 SDRAM interface; flexible 8/16-bit asynchronous memory interface; and up to two
SATA interfaces for external storage on two disk drives, or more with the use of a port multiplier.
The device also includes an SGX530 3D graphics engine (available only on the AM3894 device) to
off-load many video and imaging processing tasks from the core. Additionally, it has a complete set of
development tools for the ARM which include C compilers and a Microsoft ® Windows® debugger interface
for visibility into source code execution.
The device package has been specially engineered with Via Channel™ technology. This technology
allows 0.8-mm pitch PCB feature sizes to be used in this 0.65-mm pitch package, and substantially
reduces PCB costs. It also allows PCB routing in only two signal layers due to the increased layer
efficiency of the Via Channel™ BGA technology.

ARM Cortex-A8 RISC Processor
The ARM Cortex-A8 subsystem integrates the ARM Cortex-A8 processor. The ARM Cortex-A8 processor
is a member of ARM Cortex family of general-purpose microprocessors. This processor is targeted at
multi-tasking applications where full memory management, high performance, low die size, and low power
are all important. The ARM Cortex-A8 processor supports the ARM debug architecture and includes logic
to assist in both hardware and software debug. The ARM Cortex-A8 processor has a Harvard architecture
and provides a complete high-performance subsystem, including:
• ARM Cortex-A8 integer core
• Superscalar ARMv7 instruction set
• Thumb-2 instruction set
• Jazelle RCT acceleration
• CP14 debug coprocessor
• CP15 system control coprocessor
• NEON 64-/128-bit hybrid SIMD engine for multimedia
• Enhanced memory management unit (MMU)
• Separate level-1 instruction and data caches
• Integrated level-2 cache
• 128-bit interconnect to system memories and peripherals
• Embedded trace module (ETM).
2.3.2
Embedded Trace Module (ETM)
To support real-time trace, the ARM Cortex-A8 processor provides an interface to enable connection of an
embedded trace module (ETM). The ETM consists of two parts:
• The Trace port provides real-time trace capability for the ARM Cortex-A8.
• Triggering facilities provide trigger resources, which include address and data comparators, counter,
and sequencers.
The ARM Cortex-A8 trace port is connected to the system-level embedded trace buffer (ETB). The ETB
has a 32KB buffer memory. ETB enabled debug tools are required to read/interpret the captured trace
data.
For more details on the ETB, see Section 8.4.2.
2.3.3
ARM Cortex-A8 Interrupt Controller (AINTC)
The ARM Cortex-A8 subsystem contains an interrupt controller (AINTC) that prioritizes all service requests
from the system peripherals and generates either IRQ or FIQ to the ARM Cortex-A8 processor. For more
details on the AINTC, see Section 7.4.
2.3.4
System Interconnect
The ARM Cortex-A8 processor in connected through the arbiter to both an L3 interconnect port and a
DMM port. The DMM port is 128-bits wide and provides the ARM Cortex-A8 direct access to the DDR
memories, while the L3 interconnect port is 64-bits wide and provides access to the remaining device
modules.

Media Controller
The Media Controller has the responsibility of managing the HDVPSS module.

Inter-Processor Communication
This device is a multi-core device that requires software to efficiently manage and communicate between
the cores. The following are the main features that need to be implemented by such software:
1. Device management of the slave processors from the host processor.
2. Inter-processor communication between the cores for transfer and exchange of information between
them.
For implementing efficient inter-processor communication between the multiple cores on the device, the
following hardware features are provided:
• Mailbox interrupts
• Hardware spinlocks
Mailboxes provide a mechanism for one processor to write a value to a register and send an interrupt to
another processor. Spinlocks facilitate access to shared resources in the system.
2.5.1
Mailbox Module
PRODUCT PREVIEW
The device Mailbox module facilitates communication between the ARM Cortex-A8 and the Media
Controller. It consists of twelve mailboxes, each supporting communication between two of the above
processors. The sender sends information to the receiver by writing a message to the mailbox registers.
Interrupt signaling is used to notify the receiver that a message has been queued or to notify the sender
about an overflow situation.
The Mailbox module supports the following features (see Figure 2-2):
• 12 mailboxes
• Four-message FIFO depth for each message queue
• 32-bit message width
• Message reception and queue-not-full notification using interrupts
• Three interrupts (one to ARM Cortex-A8, two to Media Controller).

Spinlock Module
The Spinlock module provides hardware assistance for synchronizing the processes running on multiple
processors in the device:
• ARM Cortex-A8 processor
• Media Controller processors.
The Spinlock module implements 64 spinlocks (or hardware semaphores) that provide an efficient way to
perform a lock operation of a device resource using a single read-access, avoiding the need for a
read-modify-write bus transfer of which the programmable cores are not capable.

SGX530 (AM3894 only)
The SGX530 is a vector/3D graphics accelerator for vector and 3-dimensional (3D) graphics applications.
The SGX530 graphics accelerator efficiently processes a number of various multimedia data types
concurrently:
• Pixel data
• Vertex data
• Video data.
This is achieved using a multi-threaded architecture using two levels of scheduling and data partitioning
enabling zero overhead task switching.
PRODUCT PREVIEW
The SGX530 has the following major features:
• Vector graphics and 3D graphics.
• Tile-based architecture.
• Universal Scalable Shader Engine ( USSE™) - multi-threaded engine incorporating pixel and vertex
shader functionality.
• Advanced shader feature set - in excess of Microsoft® VS3.0, PS3.0, and OpenGL 2.0.
• Industry standard API support - OpenGL ES 1.1 and 2.0, OpenVG v1.1.
• Fine-grained task switching, load balancing, and power management.
• Advanced geometry direct memory access (DMA) driven operation for minimum CPU interaction.
• Programmable high-quality image anti-aliasing.
• POWERVR™ SGX core MMU for address translation from the core virtual address to the external
physical address (up to 4GB address range).
• Fully-virtualized memory addressing for OS operation in a unified memory architecture.
• Advanced and standard 2D operations [e.g., vector graphics, block level transfers (BLTs), raster
operations (ROPs)].

SPRS681A – OCTOBER 2010 – REVISED MARCH 2011
Memory Map Summary
The device has multiple on-chip memories associated with its processors and various subsystems. To
help simplify software development a unified memory map is used where possible to maintain a consistent
view of device resources across all bus masters.
The device system memory mapping is broken into four 1-GB quadrants for target address spaces
allocation. The four quadrants are labeled Q0, Q1, Q2 and Q3 for a total of 4-GB 32-bit address space.
(HDVPSS includes a thirty-third address bit for an additional 4GB of address range; this is for virtual
addressing and not physical memory addressing.) Inside each quadrant, system targets are mapped on
4-MB boundary (except EDMA targets which are decreased to 1-MB regions).
2.8.1
L3 Memory Map
Table 2-19 shows the general device level-3 (L3) memory map. The table represents the physical
addresses used by the L3 infrastructure. Some processors within the device (such as Cortex™-A8 ARM)
may re-map these targets to different virtual addresses through an internal or external MMU. Processors
without MMUs and other bus masters use these physical addresses to access L3 regions. Note that not all
masters have access to all L3 regions, but only those with defined connectivity, as shown in Table 5-1.
For a list of the specific peripherals attached to each of the Level-4 (L4) peripheral ports see Section 5.2.
The L3 interconnect returns an address-hole error if any initiator attempts to access a target to which it
has no connection.

PRODUCT PREVIEW
The L3 high-performance interconnect is based on a Network-on-Chip (NoC) interconnect infrastructure.
The NoC uses an internal packet-based protocol for forward (read command, write command with data
payload) and backward (read response with data payload, write response) transactions. All exposed
interfaces of this NoC interconnect, both for targets and initiators, comply with the OCPIP2.2 reference
standard.

TILER Extended Addressing Map
The Tiling and Isometric Lightweight Engines for Rotation (TILER) ports are mainly used for optimized 2-D
block accesses. The TILER also supports rotation of the image buffer at 0º, 90º, 180º, and 270º, with
vertical and horizontal mirroring.
The TILER includes an additional 4-GB addressing range to access the frame buffer in these rotated and
mirrored views. This range requires a thirty-third bit of address and is only accessible to peripherals that
require access to the multiple views. On the device, this is limited to the HD Video Processing Subsystem
(HDVPSS). (Other peripherals, based on ConnID, may access any one single view through the 512-MB
TILER window region located in the base 4-GB range.)
The HDVPSS may use the virtual address space of 4GB (0x1:0000:0000 – 0x1:FFFF:FFFF) since various
VPDMA clients of the HDVPSS may need to simultaneously access multiple 2-D images with different
orientations of the image buffers.
The top 4-GB address space is divided into eight sections of 512MB each. These eight sections
correspond to the eight different orientations as shown in Table 2-22.

Cortex™-A8 Memory Map
The Cortex™-A8 includes an memory management unit (MMU) to translate virtual addresses to physical
addresses which are then decoded within the Host ARM Subsystem. The subsystem includes its own
ROM and RAM, as well as configuration registers for its interrupt controller and secure state machine.
These addresses are hard-coded within the subsystem. In addition, the upper 2GB of address space is
routed to a special port (Master 0) intended for low-latency access to DDR memory. All other physical
addresses are routed to the L3 port (Master 1) where they are decoded by the device infrastructure. The
Cortex™-A8 memory map is shown in Table 2-23.

These accesses occur through the DDR DMM TILER ports. The DDR DMM splits address ranges internally to address DDR EMIF and
DDR DMM control registers based on DDR DMM tie-offs.
These addresses are routed to the Master 0 port for direct connection to the DDR DMM ELLA port.
DDR EMIF0 and DDR EMIF1 addresses may be contiguous or bank interleaved, depending on configuration of the DDR DMM.

Extensive use of pin multiplexing is used to accommodate the largest number of peripheral functions in
the smallest possible package. Pin multiplexing is controlled using a combination of hardware
configuration at device reset and software programmable register settings. For more information on pin
muxing, see Section 4.4, Pin Multiplexing Control.

Terminal Functions
The terminal functions tables identify the external signal names, the associated pin (ball) numbers along
with the mechanical package designator, the pin type, whether the pin has any internal pullup or pulldown
resistors, and a functional pin description. Bolded pin names denote the muxed pin function being
described in each table. For more detailed information on device configurations, peripheral selection,
multiplexed/shared pin, and see Section 4, Device Configurations.

4 Device Configurations
4.1
Control Module
The device control module includes status and control logic not addressed within the peripherals or the
remainder of the device infrastructure. This module is the primary point of control for the following areas of
the device:
• Functional I/O multiplexing
• Device status
• Static device configuration
• OCP interface for standard and customer programmable e-Fuse bit shift registers.
The control module primarily implements a bank of registers accessible (read/write) by the software along
with some read-only registers carrying status information. Most register bits are exported as control
signals for other logic blocks on the device. Certain control module registers have default values based
upon the device type as decoded from e-Fuse.
PRODUCT PREVIEW
The read/write registers can be divided into the following classes:
• Static device configuration registers
• Status and configuration registers
• Boot registers
Table 4-1 shows the general register groupings and Table 4-2 through Table 4-4 provide register
summaries for each group.

SPRS681A – OCTOBER 2010 – REVISED MARCH 2011
Debugging Considerations
Pullup/Pulldown Resistors
Proper board design should ensure that input pins to the device always be at a valid logic level and not
floating. This may be achieved via pullup/pulldown resistors. The device features internal pullup (IPU) and
internal pulldown (IPD) resistors on most pins to eliminate the need, unless otherwise noted, for external
pullup/pulldown resistors.
For the boot and configuration pins (listed in Table 3-1, Boot Terminal Functions), if they are both routed
out and 3-stated (not driven), it is strongly recommended that an external pullup/pulldown resistor be
implemented. Although, internal pullup/pulldown resistors exist on these pins and they may match the
desired configuration value, providing external connectivity can help ensure that valid logic levels are
latched on these device boot and configuration pins. In addition, applying external pullup/pulldown
resistors on the boot and configuration pins adds convenience to the user in debugging and flexibility in
switching operating modes.
Tips for choosing an external pullup/pulldown resistor:
• Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure
to include the leakage currents of all the devices connected to the net, as well as any internal pullup or
pulldown resistors.
• Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of
all inputs connected to the net. For a pullup resistor, this should be above the highest VIH level of all
inputs on the net. A reasonable choice would be to target the VOL or VOH levels for the logic family of
the limiting device; which, by definition, have margin to the VIL and VIH levels.
• Select a pullup/pulldown resistor with the largest possible value; but, which can still ensure that the net
will reach the target pulled value when maximum current from all devices on the net is flowing through
the resistor. The current to be considered includes leakage current plus, any other internal and
external pullup/pulldown resistors on the net.
• For bidirectional nets, there is an additional consideration which sets a lower limit on the resistance
value of the external resistor. Verify that the resistance is small enough that the weakest output buffer
can drive the net to the opposite logic level (including margin).
• Remember to include tolerances when selecting the resistor value.
• For pullup resistors, also remember to include tolerances on the DVDD rail.
For most systems, a 1-kΩ resistor can be used to oppose the IPU/IPD while meeting the above criteria.
Users should confirm this resistor value is correct for their specific application.
For most systems, a 20-kΩ resistor can be used to compliment the IPU/IPD on the boot and configuration
pins while meeting the above criteria. Users should confirm this resistor value is correct for their specific
application.
For most systems, a 20-kΩ resistor can also be used as an external PU/PD on the pins that have
IPUs/IPDs disabled and require an external PU/PD resistor while still meeting the above criteria. Users
should confirm this resistor value is correct for their specific application.
For more detailed information on input current (II), and the low-/high-level input voltages (VIL and VIH), see
Section 6.3, Electrical Characteristics Over Recommended Ranges of Supply Voltage and Operating
Temperature.

PRODUCT PREVIEW
An external pullup/pulldown resistor needs to be used in the following situations:
• Boot and Configuration Pins: If the pin is both routed out and 3-stated (not driven), an external
pullup/pulldown resistor is strongly recommended, even if the IPU/IPD matches the desired
value/state.
• Other Input Pins: If the IPU/IPD does not match the desired value/state, use an external
pullup/pulldown resistor to pull the signal to the opposite rail.

For the internal pullup/pulldown resistors for all device pins, see the peripheral/system-specific terminal
functions tables in Section 3.2.
4.3
Boot Sequence
The boot sequence is a process by which the device's memory is loaded with program and data sections,
and by which some of the device's internal registers are programmed with predetermined values. The boot
sequence is started automatically after each device-level global reset. For more details on device-level
global resets, see Section 7.2. There are several methods by which the memory and register initialization
can take place. Each of these methods is referred to as a boot mode. The boot mode to be used is
selected at reset. The device is booted through multiple means—primary bootloaders within internal ROM
or EMIF4, and secondary user bootloaders from peripherals or external memories. The maximum size of
the boot image is 255KB (ROM uses 1KB internally). Boot modes, pin configurations, and register
configurations required for booting the device, are described in the following subsections.
PRODUCT PREVIEW
The following boot modes are supported:
• NOR Flash boot (muxed and non-muxed, 8-bit or 16-bit)
• NAND Flash boot (SLC and MLC with BCH ECC, 8-bit or 16-bit)
• SPI boot (EEPROM or Flash, SPI mode 3, 24-bit)
• SD boot (SD cards)
• EMAC boot (TFTP client)
• UART boot (X-modem client)
• PCIe boot (client mode, PCIe 32 and PCIe 64).
The state of the device after boot is determined by sampling the input states of the BTMODE[4:0] pins
when device reset (POR or RESET) is deasserted. The sampled values are latched into the
CONTROL_STATUS register, which is part of the system configuration (SYSCFG) module.
The BTMODE [4:0] values determine the boot mode order according to Table 4-5. The first boot mode
listed for each BTMODE[4:0] configuration is executed as the primary boot mode. If the primary boot
mode fails, the second, third, and fourth boot modes are executed, in that order, until a successful boot is
completed.
Additional boot configuration pins determine the following system boot settings as shown in Table 3-1:
• GPMC CS0 Default Bus Width
• GPMC Wait Enable
• GPMC Address/Data Multiplexing.
The GPMC CS0 default operation is determined by the CS0BW, CS0WAIT, and CS0MUX[1:0] inputs.
For more detailed information on booting the device, see the AM38x Sitara ARM Microprocessors (MPUs)
Technical Reference Manual (literature number SPRUGX7).

Pin Multiplexing Control
Device-level pin multiplexing is controlled on a pin-by-pin basis by the MUXMODE bits of the PINCTRL1 PINCTRL321 registers in the SYSCFG module. The default state for each multiplexed pin is MUXMODE =
0x000.
Pin multiplexing selects which of several peripheral pin functions control the pin's IO buffer output data
values.
The input from each pin is routed to all of the peripherals that share the pin, regardless of the MUXMODE
setting. For details, see the table below and the MUXED column in the each of the Terminal Functions
tables in Section 3.2.

How to Handle Unused Pins
When device signal pins are unused in the system, they can be left unconnected unless otherwise
instructed in the Terminal Functions tables. For unused input pins, the internal pull resistor should be
enabled, or an external pull resistor should be used, to prevent floating inputs. All supply pins must always
be connected to the correct voltage, even when their associated signal pins are unused, as instructed in
the Terminal Functions tables in Section 3.2.

5 System Interconnect
The L3 interconnect allows the sharing of resources, such as peripherals and external or on-chip
memories, between all the initiators of the platform. The L4 interconnects control access to the
peripherals.
Transfers between initiators and targets across the platform are physically conditioned by the chip
interconnect.
5.1
L3 Interconnect
The L3 topology is driven by performance requirements, bus types, and clocking structure. Figure 5-1
shows the interconnect of the device and the main modules and subsystems in the platform. Arrows
indicate the master/slave relationship, not data flow. Master/slave connectivity is shown in Table 5-1.

L4 Interconnect
The L4 interconnect is a non-blocking peripheral interconnect that provides low-latency access to a large
number of low-bandwidth, physically-dispersed target cores. The L4 can handle incoming traffic from up to
four initiators and can distribute those communication requests to and collect related responses from up to
63 targets.
The device provides three interfaces with L3 interconnect for high-speed peripheral and standard
peripheral. Figure 5-2 and Table 5-2 show the L4 bus architecture and memory-mapped peripherals.

Data in this table is based on device operation at 1.0 GHz for the ARM Cortex-A8.
This device supports, and requires the use of, SmartReflex technology with Adaptive Voltage Scaling based on die temperature and
performance. The SmartReflex codes output from the device correspond to up to 32 linear voltage steps within the specified voltage
range, with the option to use fewer steps if desired, with a minimum of eight steps. TI requires that users design-in a supply that can
handle multiple voltage steps within this range with ± 5% tolerances. Not incorporating a flexible supply may limit the system's ability to
use the power saving capabilities of the SmartReflex technology.
For supply voltage pins, DVDD_DDRx:
• 1.5 V is used for DDR3 SDRAM.
• 1.8 V is used for DDR2 SDRAM.
Oscillator ground (DEVOSC_VSS) must be kept separate from other grounds and connected directly to the crystal load capacitor
ground.
DDR_VREF is expected to equal 0.5DVDD_DDRx of the transmitting device and to track variations in the DVDD_DDRx.
P = the period of the applied signal. Maintaining transition times as fast as possible is recommended to improve noise immunity on input
signals.

7 Power, Reset, Clocking, and Interrupts
7.1
Power Supplies
7.1.1
Voltage and Power Domains
The device has the following voltage domains:
• 1-V adaptive voltage scaling (AVS) domain - Main voltage domain for all modules
• 1-V constant domain - Memories, PLLs, DACs, DDR IOs, HDMI, and USB PHYs
• 1.8-V constant domain - PLLs, DACs, HDMI, and USB PHYs
• 3.3-V constant domain - IOs and USB PHY
• 1.5-V constant domain - DDR IOs, PCIe, and SATA SERDES
• 0.9-V constant domain - USB PHY
These domains define groups of modules that share the same supply voltage for their core logic. Each
voltage domain is powered by dedicated supply voltage rails. For the mapping between voltage domains
and the supply pins associated with each, see Table 3-30.
7.1.2
Power Domains
The device's 1-V AVS and 1-V constant voltage domains have seven power domains that supply power to
both the core logic and SRAM within their associated modules. All other voltage domains have only
always-on power domain.
Within the 1-V AVS and 1-V constant voltage domains, each power domain, except for the always-on
domain, has an internal power switch that can completely remove power from that domain. At power-up,
all domains, except always-on, come-up as power gated. Since there is an always-on domain in each
voltage domain, all power supplies are expected to be ON all the time (as long as the device is in use).
For details on powering up/down the device power domains, see the AM38x Sitara ARM Microprocessors
(MPUs) Technical Reference Manual (literature number SPRUGX7).
Note: All modules within a power domain are unavailable when the domain is powered OFF. For
instructions on powering ON/OFF the domains, see the AM38x Sitara ARM Microprocessors (MPUs)
Technical Reference Manual (literature number SPRUGX7).

•
Graphics Domain
This domain contains the SGX530 (available only on the AM8394 device).
Active Domain
The active domain has all modules that are only needed when the system is in "active" state. In any of
the standby states, these modules are not needed. This domain contains the HDVPSS peripheral.
Default Domain
The default domain contains modules that might be required even in standby mode. Having them in a
separate power domain allows customers to power gate these modules when in standby mode. This
domain has the DDR, SATA, PCIe, Media Controller and USB peripherals.
Always-On Domain
The always-on domain contains all modules that are required even when the system goes to standby
mode. This includes the host ARM and modules that generate wake-up interrupts (e.g., UART, RTC,
GPIO, EMAC) as well as other low-power I/Os.

SmartReflex™
The device contains SmartReflex modules that are required to minimize power consumption on the
voltage domains using external variable-voltage power supplies. Based on the device process,
temperature, and desired performance, the SmartReflex modules advise the host processor to raise or
lower the supply voltage to each domain for minimal power consumption. The communication link between
the host processor and the external regulators is a system-level decision and can be accomplished using
GPIOs or I2C.
The major technique employed by SmartReflex in the device is adaptive voltage scaling (AVS). Based on
the silicon process and temperature, the SmartReflex modules guide software in adjusting the core 1-V
supply voltage within the desired range. This technique is called adaptive voltage scaling (AVS). AVS
occurs continuously and in real time, helping to minimize power consumption in response to changing
operating conditions.
NOTE
Implementation of SmartReflex AVS is required for proper device operation.
7.1.5
Memory Power Management
PRODUCT PREVIEW
The device memories offer three different modes to save power when memories are not being used;
Table 7-1 provides the details.

The device provides a feature that allows the software to put the chip-level memories (OCMC RAMs) in
any of the three (LS, DS, and SD) modes. There are control registers in the control module to control the
power-down state of OCMC RAM0 and OCMC RAM1. There are also status registers that can be used
during power-up to check if memories are powered-up. For detailed instructions on entering and exiting
from light sleep and deep sleep modes, see the AM38x Sitara ARM Microprocessors (MPUs) Technical
Reference Manual (literature number SPRUGX7).
Memories inside switchable domains go to the shut down (SD) state whenever the power domain goes to
the OFF state. Memories come back to functional state along with the domain power-up.
In order to reduce SRAM leakage, many SRAM blocks can be switched from active mode to shut-down
mode. When SRAM is put in shut-down mode, the voltage supplied to it is automatically removed and all
data in that SRAM is lost.
All SRAM located in a switchable power domain (all domains except always-on) automatically enters
shut-down mode whenever its assigned associated power domain goes to the OFF state. The SRAM
returns to the active state when the corresponding power domain returns to the ON state.
For detailed instructions on powering up/down the various device SRAM, see the AM38x Sitara ARM
Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).
7.1.6
I/O Power-Down Modes
The DDR3 I/Os are put into power-down mode automatically when the default power domain is turned
OFF.
The HDMI PHY controller is in the always-on power domain, so software must configure the PHY into
power-down mode.

7.2.2
Power-On Reset (POR pin)
Power-on reset (POR) is initiated by the POR pin and is used to reset the entire chip, including the test
and emulation logic. POR is also referred to as a cold reset since it is required to be asserted when the
devices goes through a power-up cycle. However, a device power-up cycle is not required to initiate a
power-on reset.
The following sequence must be followed during a power-on reset:
1. Wait for the power supplies to reach normal operating conditions while keeping the POR pin asserted.
2. Wait for the input clock sources SERDES_CLKN/P to be stable (if used by the system) while keeping
the POR pin asserted (low).
3. Once the power supplies and the input clock source are stable, the POR pin must remain asserted
(low) for a minimum of 32 DEV_MXI cycles. Within the low period of the POR pin, the following
happens:
(a) All pins enter a Hi-Z mode.
(b) The PRCM asserts reset to all modules within the device.
(c) The PRCM begins propagating these clocks to the chip with the PLLs in bypass mode.
4. The POR pin may now be deasserted (driven high). When the POR pin is deasserted (high):
(a) The BOOT pins are latched.
(b) Reset to the ARM Cortex-A8 is de-asserted, provided the MPU clock is running.
(c) All other domain resets are released, provided the domain clocks are running.
(d) The clock, reset, and power-down state of each peripheral is determined by the default settings of
the PRCM.
(e) The ARM Cortex-A8 begins executing from the default address (either Boot ROM or GPMC).
7.2.3
External Warm Reset (RESET pin)
An external warm reset is activated by driving the RESET pin active-low. This resets everything in the
device, except the ARM Cortex-A8 interrupt controller, test, and emulation. An emulator session stays
alive during warm reset.
The following sequence must be followed during a warm reset:
1. Power supplies and input clock sources should already be stable.

2. The RESET pin must be asserted (low) for a minimum of 32 DEV_MXI cycles. Within the low period of
the RESET pin, the following happens:
(a) All pins, except test and emulation pins, enter a Hi-Z mode.
(b) The PRCM asserts reset to all modules within the device, except for the ARM Cortex-A8 interrupt
controller, test, and emulation.
(c) RSTOUT is asserted.
3. The RESET pin may now be de-asserted (driven high). When the RESET pin is de-asserted (high):
(a) The BOOT pins are latched.
(b) Reset to the ARM Cortex-A8 and modules without a local processor is de-asserted, with the
exception of the ARM Cortex-A8 interrupt controller, test, and emulation.
(c) RSTOUT is de-asserted.
(d) The clock, reset, and power-down state of each peripheral is determined by the default settings of
the PRCM.
(e) The ARM Cortex-A8 begins executing from the default address (Boot ROM).
(f) Since the ARM Cortex-A8 interrupt controller is not impacted by warm reset, application software
needs to explicitly clear all pending interrupts in the ARM Cortex-A8 interrupt controller.
Emulation Warm Reset
An emulation warm reset is activated by the on-chip emulation module. It has the same effect and
requirements as an external warm reset (RESET), with the exception that it does not re-latch the BOOT
pins.
The emulator initiates an emulation warm reset via the ICEPick module. To invoke the emulation warm
reset via the ICEPick module, the user can perform the following from the Code Composer Studio™ IDE
menu:
Debug → Advanced Resets → System Reset.
7.2.5
Watchdog Reset
A watchdog reset is initiated when the watchdog timer counter reaches zero. It has the same effect and
requirements as an external warm reset (RESET), with the exception that it does not re-latch the BOOT
pins. In addition, a watchdog reset always results in RSTOUT being asserted.
7.2.6
Software Global Cold Reset
A software global cold reset is initiated under software control. It has the same effect and requirements as
a power-on reset (POR), with the exception that it does not re-latch the BOOT pins.
Software initiates a software global cold reset by writing to RST_GLOBAL_COLD_SW in the
PRM_RST_CTRL register.
7.2.7
Software Global Warm Reset
A software global warm reset is initiated under software control. It has the same effect and requirements
as a external warm reset (RESET), with the exception that it does not re-latch the BOOT pins.
Software initiates a software global warm reset by writing to RST_GLOBAL_WARM_SW in the
PRM_RST_CTRL register.
7.2.8
Test Reset (TRST pin)
A test reset is activated by the emulator asserting the TRST pin. The only effect of a test reset is to reset
the emulation logic.

Local Reset
The local reset for various modules within the device is controlled by programming the PRCM and/or the
module's internal registers. Only the associated module is reset when a local reset is asserted, leaving the
rest of the device unaffected.
For details on local reset, see the PRCM chapter of the AM38x Sitara ARM Microprocessors (MPUs)
Technical Reference Manual (literature number SPRUGX7) and individual subsystem and peripheral
user's guides.
7.2.10 Reset Priority
If any of the above reset sources occur simultaneously, the device only processes the highest-priority
reset request. The reset request priorities, from high to low, are as follows:
1. Power-on reset (POR)
2. Test reset (TRST)
3. External warm reset (RESET)
4. Emulation warm resets
5. Watchdog reset
6. Software global cold/warm resets.
PRODUCT PREVIEW
7.2.11 Reset Status Register
The Reset Status Register (PRM_RSTST) contains information about the last reset that occurred in the
system. For more information on this register, see the PRCM chapter of the AM38x Sitara ARM
Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).
7.2.12 PCIe Reset Isolation
The device supports reset isolation for the PCI Express (PCIe) module. This means that the PCI Express
subsystem can be reset without resetting the rest of the device.
When the device is a PCI Express Root Complex (RC), the PCIe subsystem can be reset by software
through the PRCM. Software should ensure that there are no ongoing PCIe transactions before asserting
this reset by first taking the PCIe subsystem into the IDLE state by programming the register
CM_DEFAULT_PCI_CLKCTRL inside the PRCM. After bringing the PCIe subsystem out of reset, bus
enumeration should be performed again and should treat all endpoints (EP) as if they had just been
connected.
When the device is a PCI Express Endpoint (EP), the PCIe subsystem generates an interrupt when an
in-band reset is received. Software should process this interrupt by putting the PCIe subsystem in the
IDLE state and then asserting the PCIe local reset through the PRCM.
All device-level resets mentioned in the previous sections, except Test Reset, also reset the PCIe
subsystem. Therefore, the device should issue a Hot Reset to all downstream devices and re-enumerate
the bus upon coming out of reset.
7.2.13 RSTOUT
The RSTOUT pin on the device reflects device reset status. This output is always asserted when any of
the following resets occur:
• Power-on reset (POR)
• External warm reset
• Emulation warm reset (RESET)
• Software global cold/warm reset
• Watchdog timer reset.

The RSTOUT pin remains asserted until PRCM releases the host ARM Cortex-A8 processor for reset.
7.2.14 Effect of Reset on Emulation and Trace
The device emulation and trace is only reset by the following sources:
• Power-on reset (POR)
• Software global cold reset
• Test reset (TRST).
Other than these three, none of the other resets affect emulation and trace functionality.
7.2.15 Reset During Power Domain Switching
Cold reset for a power domain is asserted under either of the following two conditions:
1. A power-on reset or software global cold reset occurs.
2. When that power domain switches from the OFF state to the ON state.
7.2.16 Pin Behaviors at Reset
When any reset (other than test reset) described in Section 7.2.1 is asserted, all device pins are put into a
Hi-Z state except for:
• Emulation pins. These pins are only put into a Hi-Z state when POR or global software cold reset is
asserted.
• RSTOUT pin.
In addition, the PINCNTL registers, which control pin multiplexing, slew control, enabling the
pullup/pulldown, and enabling the receiver, are reset to their default state. For a description of the
RESET_ISO register, see the AM38x Sitara ARM Microprocessors (MPUs) Technical Reference Manual
(literature number SPRUGX7).
Internal pullup/pulldown (IPU/IPD) resistors are enabled during and immediately after reset as described in
the OTHER column in the tables in Section 3.2, Terminal Functions.
7.2.17 Reset Electrical Data/Timing
NOTE
If a configuration pin must be routed out from the device, the internal pullup/pulldown
(IPU/IPD) resistor should not be relied upon; TI recommends the use of an external
pullup/pulldown resistor.

Device Clock Inputs
The device has four on-chip PLLs and two reference clocks which are generated by on-chip oscillators. In
addition to the 27-MHz reference clock, a 100-MHz differential clock input is required for SATA and PCIe.
A third clock input is an optional 32.768-kHz clock input (no on-chip oscillator) for the RTC.
The device clock input (DEV_MXI/DEV_CLKIN) is used to generate the majority of the internal reference
clocks. An external square-wave clock can be supplied to DEV_CLKIN instead of using a crystal input.
The device clock should be 27 MHz.
Section 7.3.1.1 provides details on using the on-chip oscillators with external crystals for the 27-MHz
system oscillator.
7.3.1.1
Using the Internal Oscillators
When the internal oscillators are used to generate the device clock, external crystals are required to be
connected across the MXI and MXO pins, along with two load capacitors, as shown in Figure 7-5. The
external crystal load capacitors should also be connected to the associated oscillator ground pin
(DEVOSC_VSS). The capacitors should not be connected to board ground (VSS).

SERDES_CLKN/P Input Clock
A high-quality, low-jitter differential clock source is required for the PCIe and SATA PHYs. The clock is
required to be AC coupled to the device's SERDES_CLKP and SERDES_CLKN pins according to the
specifications in Table 7-10. Both the clock source and the coupling capacitors should be placed
physically as close as possible to the processor.
When the PCIe interface is used, the SERDES_CLKN/P clock is required to meet the REFCLK AC
specifications outlined in the PCI Express Card Electromechanical Specification (Gen.1 and Gen.2). When
the SATA interface is used, the SERDES_CLKN/P clock is required to meet the specifications in
Table 7-7. When both the PCIe and SATA interfaces are used, both sets of specifications must be met
simultaneously.

PLLs
The device contains four embedded PLLs (Main, Audio, Video and DDR) that provide clocks to different
parts of the system. For a high-level view of the device clock architecture, including the PLL reference
clock sources and connections, see Figure 7-4.
The reference clock for most of the PLLs comes from the DEV_CLKIN input clock. Also, each PLL
supports a bypass mode in which the reference clock can be directly passed to the PLL CLKOUT. All
device PLLs (except the DDR PLL) come-up in bypass mode after reset.
Flying-adder PLLs are used for all the on-chip PLLs. Figure 7-8 shows the basic structure of the
flying-adder PLL.

Figure 7-8. Flying-Adder PLL
The flying-adder PLL has two main components: a multi-phase PLL and the flying-adder synthesizer. The
multi-phase PLL takes an input reference clock (fr), multiplies it with factor, N, and provides a K-phase
output to the flying-adder synthesizer. The flying-adder synthesizer takes this multi-phase clock input and
produces a variable frequency clock (fs). There can be a post divider on this clock which takes in clock fs
and drives out clock fo. The frequency of the clock driven out is given by:
é
(Ν * Κ ) ù * fr
fo = ê
(
FREQ
* P * M )úû
ë
There can be multiple flying-adder synthesizers attached to one multi-phase PLL to generate different
frequencies. In this case, FREQ (4 bits of integer and 24 bits of fractional value) and M (1 to 255) values
can be adjusted for each clock separately, based on the frequency needed. A multi-phase PLL used in
this device has a value of K = 8.
For details on programming the device PLLs, see the PLL chapter of the AM38x Sitara ARM
Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).

PLL Locking Sequence
All of the flying-adder PLLs (except the DDR PLL) come-up in bypass mode at reset. All of the registers
(P, N, FREQ, and M) need to be programmed appropriately and then wait approximately 8 µs for
PLL_Audio and 5 µs for the other PLLS to be locked. Verification that the PLL is locked can be checked
by accessing the lock status bit in the PLL control register for each PLL (bit = 1 when the PLL is locked).
Once the PLL is locked, then the FA-PLL can be taken out of bypass mode. Control for bypass mode is
through chip-level registers. For more details on the PLL registers and bypass logic, see the PLL chapter
of the AM38x Sitara ARM Microprocessors (MPUs) Technical Reference Manual (literature number

In some cases, the system clock inputs and PLL outputs are sent to the PRCM module for division and
multiplexing before being routed to the various device modules. These clock outputs from the PRCM
module are called SYSCLKs. Table 7-14 lists the main device SYSCLKs along with their maximum
supported clock frequencies. In addition, limits shown in the table may be further restricted by the clock

CLKOUT
Figure 7-9. CLKOUT Source Selection Logic
As shown in the figure, there are four possible sources for CLKOUT, one clock from each of the four
PLLs. The selected clock can be further divided by any ratio from 1 to 1/8 before going out on the
CLKOUT pin. The default selection is to select main PLL clock5, divider set to 1/1, and clock disabled.

Cortex™-A8 Interrupts
The Cortex™-A8 Interrupt Controller (AINTC) takes ARM device interrupts and maps them to either the
interrupt request (IRQ) or fast interrupt request (FIQ) of the ARM with an individual priority level. The
AINTC interrupts must be active low-level interrupts.
The AINTC is responsible for prioritizing all service requests from the system peripherals directed to the
Cortex™-A8 SS and generating either nIRQ or nFIQ to the host. The type of the interrupt (nIRQ or nFIQ)
and the priority of the interrupt inputs are programmable. It has the capability to handle up to 128 requests
which can be steered/prioritized as nFIQ or nIRQ interrupt requests.
The general features of the AINTC are:
• Up to 128 level-sensitive interrupts inputs
• Individual priority for each interrupt input
• Each interrupt can be steered to nFIQ or nIRQ
• Independent priority sorting for nFIQ and nIRQ
• Secure mask flag.

Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data manual do not include delays by board routings. 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 utilizing 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.
For the DDR2/3, PCIe, SATA, USB, and HDMI interfaces, IBIS models are not used for timing
specification. TI provides, in this document, a PCB routing rule solution for each interface that describes
the routing rules used to ensure the interface timings are met. Video DAC guidelines (Section 8.10.3) are
also included to discuss important layout considerations.
8.2
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.

DDR2 Interface
This section provides the timing specification for the DDR2 interface as a PCB design and manufacturing
specification. The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk,
and signal timing. These rules, when followed, result in a reliable DDR2 memory system without the need
for a complex timing closure process. For more information regarding the guidelines for using this DDR2
specification, see Understanding TI’s PCB Routing Rule-Based DDR2 Timing Specification Application
Report (SPRAAV0).

8.3.1.2.5 DDR2 Keepout Region
The region of the PCB used for the DDR2 circuitry must be isolated from other signals. The DDR2
keepout region is defined for this purpose and is shown in Figure 8-8. The size of this region varies with
the placement and DDR routing. Additional clearances required for the keepout region are shown in
Table 8-5.

Figure 8-8. DDR2 Keepout Region
NOTE
The region shown in 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 t hey 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 1.8V 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.
8.3.1.2.6 Bulk Bypass Capacitors
Bulk bypass capacitors are required for moderate speed bypassing of the DDR2 and other circuitry.
Table 8-6 contains the minimum numbers and capacitance required for the bulk bypass capacitors. Note
that this table only covers the bypass needs of the DDR2 interfaces and DDR2 device. Additional bulk
bypass capacitance may be needed for other circuitry.

VREFSSTL_DDR is used as a reference by the input buffers of the DDR2 memories as well as the MPU.
VREF is intended to be half the DDR2 power supply voltage and should be created using a resistive

8.3.2.1.1 DDR3 versus DDR2
This specification only covers AM389x MPU PCB designs that utilize DDR3 memory. Designs using DDR2
memory should use the PCB design specifications for DDR2 memory in Section 8.3.1. While similar, the
two memory systems have different requirements. It is currently not possible to design one PCB that
covers both DDR2 and DDR3.

This table is per EMIF.
Two DDR3 devices are mirrored when one device is placed on the top of the board and the second device is placed on the bottom of
the board.
This is two mirrored pairs of DDR3 devices.
8.3.2.2.1 DDR3 EMIFs
The MPU contains two separate DDR3 EMIFs. This specification covers one of these EMIFs (DDR[0])
and, thus, needs to be implemented twice, once for each EMIF. The PCB layout generally turns out to be
a semi-mirror with DDR[1] being a flipped version of DDR[0]; the only exception being the DDR3 devices
themselves are not flipped unless mounted on opposite sides of the PCB. Requirements are identical
between the two EMIFs.

DDR3 Interface Schematic
8.3.2.3.1 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 8-13 and Figure 8-14 show the schematic connections for 32-bit
interfaces using x16 devices.
8.3.2.3.2 16-Bit DDR3 Interface
Note that the 16-bit wide interface schematic is practically identical to the 32-bit interface (see Figure 8-13
and Figure 8-14); only the high-word DDR memories are removed and the unused DQS inputs are tied off.
The MPU DDR[x]_DQS[2] and DDR[x]_DQS[3] pins should be pulled to the DDR supply via 1-kΩ
resistors. Similarly, the DDR[x]_DQS[2] and DDR[x]_DQS[3] pins should be pulled to ground via 1-kΩ
resistors.
When not using a DDR interface, the proper method of handling the unused pins is to tie off the DQS pins
by pulling the non-inverting DQS pin to the DDR_1V5 supply via a 1k-Ω resistor and pulling the inverting
DQSn pin to ground via a 1k-Ω resistor. This needs to be done for each byte not used. Also, include the
50-Ω pulldown for DDR[x]_VTP. 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.

The minimum stackup for routing the DDR3 interface is a four-layer stack up as shown in Table 8-16.
Additional layers may be added to the PCB stackup to accommodate other circuitry, enhance SI/EMI
performance, or to reduce the size of the PCB footprint. A six-layer stackup is shown in Table 8-17.
Complete stackup specifications are provided in Table 8-18.

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.
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.
Reference planes are to be directly adjacent to the signal plane to minimize the size of the return current loop.
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.
For the DDR3 device BGA pad size, see the DDR3 device manufacturer documentation.
Z is the nominal singled-ended impedance selected for the PCB specified by item 13.

Placement
Figure 8-15 shows the required placement for the MPU as well as the DDR3 devices. The dimensions for
this figure are defined in Table 8-19. 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 device(s) are
omitted from the placement.

Non-DDR3 signals allowed within DDR3 keepout region provided they are separated from DDR3 routing layers by a ground plane.
Note that DDR3 signals from one DDR3 controller are considered non-DDR3 to the other controller. In other words, keep the two DDR3
interfaces separated by this specification.
8.3.2.7
DDR3 Keepout Region
The region of the PCB used for DDR3 circutry must be isolated from other signals. The DDR3 keepout
region is defined for this purpose and is shown in Figure 8-16. The size of this region varies with the
placement and DDR routing. Additional clearances required for the keepout region are shown in
Table 8-19. 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 DDR3 controller's signals should be separated from each other by the specification in
Table 8-19, item 5.

Bulk Bypass Capacitors
Bulk bypass capacitors are required for moderate speed bypassing of the DDR3 and other circuitry.
Table 8-20 contains the minimum numbers and capacitance required for the bulk bypass capacitors. Note
that this table only covers the bypass needs of the DDR3 controllers and DDR3 device(s). Additional bulk
bypass capacitance may be needed for other circuitry. Also note that Table 8-20 is per DDR3 controller;
thus, systems using both controllers have to meet the needs of Table 8-20 twice, once for each controller.

These devices should be placed near the devices they are bypassing, but preference should be given to the placement of the
high-speed (HS) bypass capacitors and DDR3 signal routing.
8.3.2.9
High-Speed Bypass Capacitors
PRODUCT PREVIEW
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, MPU/DDR power, and
MPU/DDR ground connections. Table 8-21 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 8-21.

(7) Per DDR3 device.
(8) An additional HS bypass capacitor can share the connection vias only if it is mounted on the opposite side of the board. No sharing of
vias is permitted on the same side of the board.
(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.
8.3.2.9.1 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. Since these are returns for signal current, the signal via size may be used for these capacitors.

8.3.2.11 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.
8.3.2.12 VREFSSTL_DDR Routing
VREFSSTL_DDR (VREF) is used as a reference by the input buffers of the DDR3 memories as well as
the MPU. VREF is intended to be half the DDR3 power supply voltage and is typically generated with the
DDR3 1.5-V 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.
8.3.2.13 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.
8.3.2.14 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 differiential.
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 8-24.

Two DDR3 devices are supported on the DDR EMIF consisting of two x8 DDR3 devices arranged as one
bank (CS), 16 bits wide, or two x16 DDR3 devices arranged as one bank (CS), 32 bits wide. These two
devices may be mounted on a single side of the PCB, or may be mirrored in a pair to save board space at
a cost of increased routing complexity and parts on the backside of the PCB.

8.3.2.16 Routing Specification
8.3.2.16.1 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.
(A)
A1
A8
PRODUCT PREVIEW
Given the clock and address pin locations on the MPU and the DDR3 memories, the maximum possible
Manhattan distance can be determined given the placement. Figure 8-37 and Figure 8-38 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; i.e., 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 8-24.

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 caculation. 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.

Center-to-center spacing is allowed to fall to minimum (w) for up to 1250 mils of routed length.
The ADDR_CTRL net class of the other DDR EMIF is considered other DDR3 trace spacing.
CK spacing set to ensure proper differential impedance.
Source termination (series resistor at driver) is specifically not allowed.
Termination values should be uniform across the net class.
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 MPU and the DDR3 memories, the maximum possible
Manhattan distance can be determined given the placement. Figure 8-39 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 8-25.

DQLM1 = DQLMX1 + DQLMY1
DQLM2 = DQLMX2 + DQLMY2
DQLM3 = DQLMX3 + DQLMY3

DQLMn is the longest Manhattan distance of a byte. For definition, see Section 8.3.2.16.2 and Figure 8-39.
DQLM0 is the longest Manhattan length for the net classes of Byte 0.
DQLM1 is the longest Manhattan length for the net classes of Byte 1.
DQLM2 is the longest Manhattan length for the net classes of Byte 2.
DQLM3 is the longest Manhattan length for the net slasses of Byte 3.
Length matching is only done within a byte. Length matching across bytes is neither required nor recommended.
Each DQS pair is length matched to its associated byte.
Center-to-center spacing is allowed to fall to minimum for up to 1250 mils of routed length.
Other DDR3 trace spacing means other DDR3 net classes not within the byte.
This applies to spacing within the net classes of a byte.
DQS pair spacing is set to ensure proper differential impedance.

Emulation Features and Capability
Advanced Event Triggering (AET)
The device supports Advanced Event Triggering (AET). This capability can be used to debug complex
problems as well as understand performance characteristics of user applications. AET provides the
following capabilities:
• Hardware Program Breakpoints: specify addresses or address ranges that can generate events such
as halting the processor or triggering the trace capture.
• Data Watchpoints: specify data variable addresses, address ranges, or data values that can generate
events such as halting the processor or triggering the trace capture.
• Counters: count the occurrence of an event or cycles for performance monitoring.
• State Sequencing: allows combinations of hardware program breakpoints and data watchpoints to
precisely generate events for complex sequences.
PRODUCT PREVIEW
For more information on AET, see the following documents:
• Using Advanced Event Triggering to Find and Fix Intermittent Real-Time Bugs application report
(literature number SPRA753)
• Using Advanced Event Triggering to Debug Real-Time Problems in High Speed Embedded
Microprocessor Systems application report (literature number SPRA387)
8.4.2
Trace
The device supports Trace at the Cortex™-A8 and System levels. Trace is a debug technology that
provides a detailed, historical account of application code execution, timing, and data accesses. Trace
collects, compresses, and exports debug information for analysis. The debug information can be exported
to the Embedded Trace Buffer (ETB), or to the 5-pin Trace Interface (system trace only). Trace works in
real-time and does not impact the execution of the system.
For more information on board design guidelines for Trace Advanced Emulation, see the Emulation and
Trace Headers Technical Reference Manual (literature number SPRU655).
8.4.3
IEEE 1149.1 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 TRST 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 TRST pin to
ensure that TRST is always asserted upon power up and the device's internal emulation logic is always
properly initialized. JTAG controllers from Texas Instruments actively drive TRST high. However, some
third-party JTAG controllers may not drive TRST high but expect the use of a pullup resistor on TRST.
When using this type of JTAG controller, assert TRST to initialize the device after powerup and externally
drive TRST high before attempting any emulation or boundary-scan operations.
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)

IEEE 1149.7 cJTAG
Besides the standard (legacy) JTAG mode of operation, the target debug interface can also be switched to
a compressed JTAG (cJTAG) mode of operation, commonly referred to as IEEE1149.7 standard. An
IEEE1149.7 adapter module runs a 2-pin communication protocol on top of an IEEE1149.1 JTAG TAP.
The debug-IP logic serializes the IEEE1149.1 transactions, using a variety of compression formats, to
reduce the number of pins needed to implement a JTAG debug port. This device implements only a
subset of the IEEE1149.7 protocol; it supports Class 0/1 operation. On this device the cJTAG ID[7:0] is
tied to 0x00.
NOTE
The default setting of the scan port is IEEE 1149.1. A cJTAG emulator connected only to
TCLK and TMS can re-configure the port to cJTAG by scanning in a special command
sequence. For the scan sequence required to switch modes, see the IEEE1149.7
specification.

Enhanced Direct Memory Access (EDMA) Controller
The EDMA controller handles all data transfers between memories and the device slave peripherals on
the device. These data transfers include cache servicing, non-cacheable memory accesses,
user-programmed data transfers, and host accesses.
8.5.1
EDMA Channel Synchronization Events
The EDMA channel controller supports up to 64 channels that service peripherals and memory. Each
EDMA channel is mapped to a default EDMA synchronization event as shown in Table 8-34. By default,
each event uses the parameter entry that matches its event number. However, because the device
includes a channel mapping feature, each event may be mapped to any of 512 parameter table entries.
For more detailed information on the EDMA module and how EDMA events are enabled, captured,
processed, linked, chained, and cleared, etc., see the EDMA chapter in the AM38x Sitara ARM
Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).

Ethernet Media Access Controller (EMAC)
The device includes two Ethernet Media Access Controller (EMAC) modules which provide an efficient
interface between the device and the networked community. The EMAC supports 10Base-T (10
Mbits/second [Mbps]) and 100Base-TX (100 Mbps) in either half- or full-duplex mode, and 1000Base-T
(1000 Mbps) in full-duplex mode, with hardware flow control and quality-of-service (QOS) support. The
EMAC controls the flow of packet data from the device to an external PHY. A single MDIO interface is
pinned out to control the PHY configuration and status monitoring. Multiple external PHYs can be
controlled by the MDIO interface.
The EMAC module conforms to the IEEE 802.3-2002 standard, describing the Carrier Sense Multiple
Access with Collision Detection (CSMA/CD) Access Method and Physical Layer specifications. The IEEE
802.3 standard has also been adopted by ISO/IEC and re-designated as ISO/IEC 8802-3:2000(E).
Deviating from this standard, the EMAC module does not use the transmit coding error signal, MTXER.
Instead of driving the error pin when an underflow condition occurs on a transmitted frame, the EMAC
intentionally generates an incorrect checksum by inverting the frame CRC so that the transmitted frame is
detected as an error by the network. In addition, the EMAC I/Os operate at 3.3 V and are not compatible
with 2.5-V I/O signaling; therefore, only Ethernet PHYs with 3.3-V I/O interface should be used. The
EMAC module incorporates 8K bytes of internal RAM to hold EMAC buffer descriptors and contains the
necessary components to enable the EMAC to make efficient use of device memory and control device
interrupts.
PRODUCT PREVIEW
The EMAC module on the device supports two interface modes: Media Independent Interface (MII) and
Gigabit Media Independent Interface (GMII). The MII and GMII interface modes are defined in the IEEE
802.3-2002 standard. The EMAC uses the same pins for the MII and GMII modes of operation. Only one
mode can be used at a time.
The MII and GMII modes-of-operation pins are as follows:
• MII: EMAC[1:0]_TXCLK, EMAC[1:0]_RXCLK, EMAC[1:0]_TXD[3:0], EMAC[1:0]_RXD[3:0],
EMAC[1:0]_TXEN, EMAC[1:0]_RXDV, EMAC[1:0]_RXER, EMAC[1:0]_COL, EMAC[1:0]_CRS,
MDIO_MCLK, and MDIO_MDIO.
• GMII: EMAC[1:0]_GMTCLK, EMAC[1:0]_TXCLK, EMAC[1:0]_RXCLK, EMAC[1:0]_TXD[7:0],
EMAC[1:0]_RXD[7:0], EMAC[1:0]_TXEN, EMAC[1:0]_RXDV, EMAC[1:0]_RXER, EMAC[1:0]_COL,
EMAC[1:0]_CRS, MDIO_MCLK, and MDIO_MDIO.
For more detailed information on the EMAC module, see the EMAC/MDIO chapter in the AM38x Sitara
ARM Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).

Management Data Input/Output (MDIO)
The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to
enumerate all PHY devices in the system.
The MDIO module implements the 802.3 serial management interface to interrogate and control Ethernet
PHY(s) using a shared two-wire bus. Host software uses the MDIO module to configure the
auto-negotiation parameters of each PHY attached to the EMAC, retrieve the negotiation results, and
configure required parameters in the EMAC module for correct operation. The module is designed to allow
almost transparent operation of the MDIO interface, with very little maintenance from the core processor.
A single MDIO interface is pinned out to control the PHY configuration and status monitoring. Multiple
external PHYs can be controlled by the MDIO interface.
For more detailed information on the MDIO peripheral, see the EMAC/MDIO chapter in the AM38x Sitara
ARM Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).

The GPIO peripheral provides general-purpose pins that can be configured as either inputs

or outputs.
output pin.
an internal
generation
The device GPIO peripheral supports the following:
• Up to 64 3.3-V GPIO pins, GP0[31:0] and GP1[31:0] (the exact number available varies as a function
of the device configuration). Each channel can be configured to be used in the following applications:
– Data input/output
– Keyboard interface with a de-bouncing cell
– Synchronous interrupt generation (in active mode) upon the detection of external events (signal
transition(s) and/or signal level(s)).
• Synchronous interrupt requests from each channel are processed by two identical interrupt generation
sub-modules to be used independently by the ARM. Interrupts can be triggered by rising and/or falling
edge, specified for each interrupt-capable GPIO signal.
• Shared registers can be accessed through "Set & Clear" protocol. Software writes 1 to corresponding
bit position(s) to set or to clear GPIO signal(s). This allows multiple software processes to toggle GPIO
output signals without critical section protection (disable interrupts, program GPIO, re-enable interrupts,
to prevent context switching to another process during GPIO programming).
• Separate input/output registers.
• Output register in addition to set/clear so that, if preferred by software, some GPIO output signals can
be toggled by direct write to the output register(s).
• Output register, when read, reflects output drive status. This, in addition to the input register reflecting
pin status and open-drain I/O cell, allows wired logic to be implemented.
For more detailed information on GPIOs, see the GPIO chapter in the AM38x Sitara ARM
Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).

General-Purpose Memory Controller (GPMC) and Error Locator Module (ELM)
The GPMC is a device memory controller used to provide a glueless interface to external memory devices
such as NOR Flash, NAND Flash (with BCH and Hamming Error Code Detection for 8-bit or 16-bit NAND
Flash), SRAM, and Pseudo-SRAM. It includes flexible asynchronous protocol control for interface to
SRAM-like memories and custom logic (FPGA, CPLD, ASICs, etc.).
Other supported features include:
• 8-/16-bit wide multiplexed address/data bus
• Up to 6 chip selects with up to 256M-byte address space per chip select pin
• Non-multiplexed address/data mode
• Pre-fetch and write posting engine associated with system DMA to get full performance from NAND
device with minimum impact on NOR/SRAM concurrent access.
PRODUCT PREVIEW
The device also contains an Error Locator Module (ELM) which is used to extract error addresses from
syndrome polynomials generated using a BCH algorithm. Each of these polynomials gives a status of the
read operations for a 512 bytes block from a NAND flash and its associated BCH parity bits, plus
optionally spare area information. The ELM has the following features:
• 4-bit, 8-bit, and 16-bit per 512-byte block error location based on BCH algorithms
• Eight simultaneous processing contexts
• Page-based and continuous modes
• Interrupt generation on error location process completion
– When the full page has been processed in page mode
– For each syndrome polynomial in continuous mode.
For more detailed information on the GPMC, see the GPMC chapter in the AM38x Sitara ARM
Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).

Parameter M expression is given as one example of GPMC programming. The IO DIR signal goes from IN to OUT after both
RdCycleTime and BusTurnAround completion. Behavior of the IO direction signal depends on the kind of successive read/write
accesses performed to the memory and multiplexed or non-multiplexed memory addressing scheme, whether the bus keeping feature is
enabled or not. The IO DIR behavior is automatically handled by the GPMC controller.

M = ((RdCycleTime - CSOnTime) * (TimeParaGranularity + 1) - 0.5 * CSExtraDelay) * GPMC_FCLK.
Parameter M expression is given as one example of GPMC programming. The IO DIR signal goes from IN to OUT after both
RdCycleTime and BusTurnAround completion. Behavior of the IO direction signal depends on the kind of successive read/write
accesses performed to the memory and multiplexed or non-multiplexed memory addressing scheme, whether the bus keeping feature is
enabled or not. The IO DIR behavior is automatically handled by the GPMC controller.

8.9.1
HDMI Interface Design Guidelines
This section provides PCB design and layout guidelines for the HDMI interface. The design rules constrain
PCB trace length, PCB trace skew, signal integrity, cross-talk, and signal timing. Simulation and system
design work has been done to ensure the HDMI interface requirements are met.
8.9.1.1
HDMI Interface Schematic
The HDMI bus is separated into three main sections:
1. Transition Minimized Differential Signaling (TMDS) high-speed digital video interface
2. Display Data Channel (I2C bus for configuration and status exchange between two devices)
3. Consumer Electronics Control (optional) for remote control of connected devices.
The DDC and CEC are low-speed interfaces, so nothing special is required for PCB layout of these
signals. Their connection is shown in Figure 8-67.
The TMDS channels are high-speed differential pairs and, therefore, require the most care in layout.
Specifications for TMDS layout are below.
Figure 8-67 shows the HDMI interface schematic. The specific pin numbers can be obtained from
Table 3-7, HDMI Terminal Functions.

8.9.1.2
TMDS Routing
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 are extremely difficult to closely couple 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.
Loosely coupled PCB differential signals make impedance control much easier. Wider traces and spacing
make obstacle avoidance easier, and trace width variations do not affect impedance as much; therefore, it
is easier to maintain an accurate impedance over the length of the signal. The wider traces also show
reduced skin effect and, therefore, often result in better signal integrity.
Table 8-62 shows the routing specifications for the TMDS signals.

8.9.1.3
DDC Signals
As shown in Figure 8-67, the DDC connects just like a standard I2C bus. As such, resistor pullups must
be used to pull up the open drain buffer signals unless they are integrated into the ESD protection chip
used. If used, these pullup resistors should be connected to a 3.3-V supply.
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 protection and to translate I2C voltage levels from the 3.3 V supplied by the device
to the 5 volts required by the HDMI specification.
When selecting an ESD protection chip, choose the lowest capacitance ESD protection available to
minimize signal degradation. In no case should the ESD protection circuit capacitance be more than 5 pF.
TI manufactures devices that provide ESD protection for HDMI signals such as the TPD12S521. For more
information see the www.ti.com website.

8.10.3 Video DAC Guidelines and Electrical Data/Timing
The device's analog video DAC outputs are designed to drive a 37.5-Ω load. Figure 8-71 describes a
typical circuit that permits connecting the analog video output from the device to standard 75-Ω impedance
video systems. The device requires the use of a buffer to drive the actual video outputs, so one solution is
to use a video amplifier with integrated buffer and internal filter, such as the Texas Instruments THS7360,
which provides a complete solution for the typical output circuit shown in Figure 8-71.

Figure 8-71. Typical Output Circuits for Analog Video from DACs
PRODUCT PREVIEW
During board design, the onboard traces and parasitics must be matched for the channel. The video DAC
output pin (IOUTx) is a very high-frequency analog signal and must be routed with extreme care. As a
result, the path of this signal must be as short as possible, and as isolated as possible from other
interfering signals. The load resistor and amplifier/buffer should be placed close together and as close as
possible to the device pins. Other layout guidelines include:
• Take special care to bypass the DAC power supply pin with a capacitor.
• Place the 75-Ω resistor as close as possible (<0.5") to the amplifier/buffer (THS7360) output pin.
• To maintain a high quality video signal, 75-Ω (±10%) characteristic impedance traces should be used
after the 75-Ω series resistor.
• Minimize input trace lengths to the device to reduce parasitic capacitance.
• Include solid ground return paths.
• Match trace lengths as close as possible within a video format group (i.e., Y, Pb, and Pr for component
output, and Y and C for s-video output should match each other).
For additional video DAC design guidelines, see the HDVPSS chapter in the AM38x Sitara ARM
Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).

8.12 Multichannel Audio Serial Port (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 intercomponent digital audio interface transmission
(DIT).
8.12.1 McASP Device-Specific Information
The device includes three multichannel audio serial port (McASP) interface peripherals (McASP0,
McASP1, and McASP2). The McASP module consists of a transmit and receive section. These sections
can operate completely independently with different data formats, separate master clocks, bit clocks, and
frame syncs or, alternatively, the transmit and receive sections may be synchronized. The McASP module
also includes shift registers that may be configured to operate as either transmit data or receive data. The
transmit section of the McASP can transmit data in either a time-division-multiplexed (TDM) synchronous
serial format or in a digital audio interface (DIT) format where the bit stream is encoded for S/PDIF,
AES-3, IEC-60958, CP-430 transmission. The receive section of the McASP peripheral supports the TDM
synchronous serial format.
PRODUCT PREVIEW
The McASP module can support one transmit data format (either a TDM format or DIT format) and one
receive format at a time. All transmit shift registers use the same format and all receive shift registers use
the same format; however, the transmit and receive formats need not be the same. Both the transmit and
receive sections of the McASP also support burst mode, which is useful for non-audio data (for example,
passing control information between two devices).
The McASP peripheral has additional capability for flexible clock generation and error detection/handling,
as well as error management.
The device McASP0 module has six serial data pins, while McASP1 and McASP2 are limited to two serial
data pins each.
The McASP FIFO size is 256 bytes and two DMA and two interrupt requests are supported. Buffers are
used transparently to better manage DMA, which can be leveraged to manage data flow more efficiently.
For more detailed information on and the functionality of the McASP peripheral, see the McASP chapter in
the AM38x Sitara ARM Microprocessors (MPUs) Technical Reference Manual (literature number
SPRUGX7).

8.13 Multichannel Buffered Serial Port (McBSP)
The McBSP provides these functions:
• Full-duplex communication
• Double-buffered data registers, which allow a continuous data stream
• Independent framing and clocking for receive and transmit
• Direct interface to industry-standard codecs, analog interface chips (AICs), and other serially
connected analog-to-digital (A/D) and digital-to-analog (D/A) devices
• Supports TDM, I2S, and similar formats
• External shift clock or an internal, programmable frequency shift clock for data transfer
• 5KB Tx and Rx buffer
• Supports three interrupt and two DMA requests.
PRODUCT PREVIEW
The McBSP module may support two types of data transfer at the system level:
• The full-cycle mode, for which one clock period is used to transfer the data, generated on one edge
and captured on the same edge (one clock period later).
• The half-cycle mode, for which one half clock period is used to transfer the data, generated on one
edge and captured on the opposite edge (one half clock period later). Note that a new data is
generated only every clock period, which secures the required hold time. The interface clock
(CLKX/CLKR) activation edge (data/frame sync capture and generation) has to be configured
accordingly with the external peripheral (activation edge capability) and the type of data transfer
required at the system level.
For more detailed information on the McBSP peripheral, see the McBSP chapter in the AM38x Sitara ARM
Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).
The following sections describe the timing characteristics for applications in normal mode (that is, the
McBSP connected to one peripheral) and TDM applications in multipoint mode.

For more detailed information on the PCIe port peripheral module, see the PCIe chapter in the AM38x
Sitara ARM Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).
The PCIe peripheral on the device conforms to the PCI Express Base 2.0 Specification.
8.14.1 PCIe Design and Layout Guidelines
8.14.1.1 Clock Source
A standard 100-MHz PCIe differential clock source must be used for PCIe operation (for details, see
Section 7.3.2).
8.14.1.2 PCIe Connections and Interface Compliance
The PCIe interface on the device is compliant with the PCI Express Base 2.0 Specification. Refer to the
PCIe specifications for all connections that are described in it. For coupling capacitor selection, see
Section 8.14.1.2.1.
The use of PCIe-compatible bridges and switches is allowed for interfacing with more than one other
processor or PCIe device.
8.14.1.2.1 Coupling Capacitors
AC coupling capacitors are required on the transmit data pair. Table 8-85 shows the requirements for
these capacitors.

8.14.1.2.2 Polarity Inversion
The PCIe specification requires polarity inversion support. This means, for layout purposes, polarity is
unimportant since each signal can change its polarity on-die inside the chip. This means polarity within a
lane is unimportant for layout.
8.14.1.2.3 Lane Reversal
The device supports lane reversal. Since there are two lanes, this means the lanes can be switched in
layout for better PCB routing.
8.14.1.3 Non-Standard PCIe Connections
The following sections contain suggestions for any PCIe connection that is not described in the official
PCIe specification, such as an on-board device-to-device connection, or device-to-other PCIe-compliant
processor connection.

8.14.1.3.2 Routing Specifications
The PCIe data signal traces must be routed to achieve 100 Ω (±20%) differential impedance and 60 Ω
(±15%) 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.
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.
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.
Loosely coupled PCB differential signals make impedance control much easier. Wider traces and spacing
make obstacle avoidance easier, and trace width variations do not affect impedance as much; therefore, it
is easier to maintain an accurate impedance over the length of the signal. The wider traces also show
reduced skin effect and, therefore, often result in better signal integrity.

8.15 Real-Time Clock (RTC)
The real-time clock is a precise timer that can generate interrupts on intervals specified by the user.
Interrupts can occur every second, minute, hour, or day. The clock, itself, can track the passage of real
time for durations of several years, provided it has a sufficient power source the whole time.
The basic purpose for the RTC is to keep time of day. The other equally important purpose of the RTC is
for Digital Rights management. Some degree of tamper-proofing is needed to ensure that simply stopping,
resetting, or corrupting the RTC does not go unnoticed; so, if this occurs, the application can re-acquire
the time of day from a trusted source. The final purpose of RTC is to wake up the rest of the device from a
power-down state. The RTC features include:
• Time information (hours/minutes/seconds) directly in binary coded decimal (BCD), for easy decoding.
• Calendar information (day/month/year/day of week) directly in BCD code up to year 2099.
• Shadow time and calendar access; ease of reading time.
• Interrupt generation, periodically (1d/1h/1m/1s) or at a precise time of day and/or date.
• 30-second time correction (crystal frequency compensation).
• OCP slave port for register access.
• Supports power idle protocol with SWakeUp capable on alarm or timer events.
PRODUCT PREVIEW
The RTC is driven by SYSCLK18 (32.768 kHz) or an optional 32.768-kHz clock can be input on the
CLKIN32 clock input pin for RTC reference.
Figure 8-78 shows the major components of the RTC.

8.17.1.4 Routing Specifications
PRODUCT PREVIEW
The SATA data signal traces must be routed to achieve 100 Ω (±20%) differential impedance and 60 Ω
(±15%) 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.
60 Ω is chosen for the single-ended impedance to minimize problems caused by too low an impedance.
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 100 Ω differential impedance and 60 Ω single-ended impedance traces as possible. For best
accuracy, work with your PCB fabricator to ensure this impedance is met.

SPRS681A – OCTOBER 2010 – REVISED MARCH 2011
8.18 Serial Peripheral Interface (SPI)
The SPI is a high-speed synchronous serial input/output port that allows a serial bit stream of programmed
length (4 to 32 bits) to be shifted into and out of the device at a programmed bit-transfer rate. The SPI is
normally used for communication between the device and external peripherals. Typical applications
include an interface-to-external I/O or peripheral expansion via devices such as shift registers, display
drivers, SPI EEPROMs, and analog-to-digital converters (ADCs).
The SPI supports the following features:
• Master/slave operation
• Four chip selects for interfacing/control to up to four SPI slave devices and connection to a single
external master
• 32-bit shift register
• Buffered receive/transmit data register per channel (1 word deep), FIFO size is 64 bytes
• Programmable SPI configuration per channel (clock definition, enable polarity and word width)
• Supports one interrupt request and two DMA requests per channel.
For more detailed information on the SPI, see the SPI chapter in the AM38x Sitara ARM Microprocessors
(MPUs) Technical Reference Manual (literature number SPRUGX7).

This timing applies to all configurations regardless of SPI_CLK polarity and which clock edges are used to drive output data and capture
input data.
Related to the SPI_CLK maximum frequency.
Maximum frequency = 48 MHz
P = SPICLK period.
SPI_CLK phase is programmable with the PHA bit of the SPI_CH(i)CONF register.
B = (TCS + 0.5) * TSPICLKREF * Fratio, where TCS is a bit field of the SPI_CH(i)CONF register and Fratio = Even ≥2.
When P = 20.8 ns, A = (TCS + 1) * TSPICLKREF, where TCS is a bit field of the SPI_CH(i)CONF register. When P > 20.8 ns, A = (TCS

8.19 Timers
The device has seven 32-bit general-purpose (GP) timers that have the following features:
• Timers 1-3 are for software use and do not have an external connection
• 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
• Timer[7:1] functional clock is sourced from either the 27-MHz system clock, 32.768-kHz RTC clock or
the TCLKIN external timer input clock, as selected within the PRCM
• On-the-fly read/write register (while counting)
• Generates interrupts to the ARM CPUs.
PRODUCT PREVIEW
The device has one system watchdog timer that has 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
• Two possible clock sources:
– Internal 32.768-kHz clock derived from 27-MHz system clock.
– External clock input on the CLKIN32 input pin.
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.
For more detailed information, see the Timers chapter in the AM38x Sitara ARM Microprocessors (MPUs)
Technical Reference Manual (literature number SPRUGX7).

SPRS681A – OCTOBER 2010 – REVISED MARCH 2011
8.20 Universal Asynchronous Receiver/Transmitter (UART)
The UART performs serial-to-parallel conversions on data received from a peripheral device and
parallel-to-serial conversion on data received from the CPU. The device provides up to three UART
peripheral interfaces, depending on the selected pin multiplexing.
UART functions include:
• Baud-rate up to 3.6 Mbit/s
• Programmable serial interfaces characteristics
– 5, 6, 7, or 8-bit characters
– Even, odd, or no parity-bit generation and detection
– 1, 1.5, or 2 stop-bit generation
– Flow control: hardware (RTS/CTS) or software (XON/XOFF)
• Additional modem control functions (UART0_DTR, UART0_DSR, UART0_DCD, and UART0_RIN) for
UART0 only; UART1 and UART2 do not support full-flow control signaling.
IR-IrDA functions include:
• Support of IrDA 1.4 slow infrared (SIR, baud-rate up to 115.2 Kbits/s), medium infrared (MIR,
baud-rate up to 1.152 Mbits/s) and fast infrared (FIR baud-rate up to 4.0 Mbits/s) communications
• Supports framing error, cyclic redundancy check (CRC) error, illegal symbol (FIR), and abort pattern
(SIR, MIR) detection
• 8-entry status FIFO (with selectable trigger levels) available to monitor frame length and frame errors.
IR-CIR functions include:
• Consumer infrared (CIR) remote control mode with programmable data encoding
• Free data format (supports any remote control private standards)
• Selectable bit rate and configurable carrier frequency.
For more detailed information on the UART peripheral, see the UART chapter in the AM38x Sitara ARM
Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7).

The transmission control register (TCR) and the trigger level register (TLR) are accessible only when EFR[4]=1 and MCR[6]=1.
MCR[7:5] and FCR[5:4] can only be written when EFR[4]=1.
In UART modes, IER[7:4] can only be written when EFR[4]=1. In IrDA/CIR modes, EFR[4] has no impact on the access to IER[7:4].

8.21 Universal Serial Bus (USB2.0)
The USB2.0 modules do not support the following features:
• On-chip charge pump (VBUS power must be generated external to the device)
• RNDIS mode acceleration for USB sizes that are not multiples of 64 bytes
• Endpoint max USB packet sizes that do not conform to the USB2.0 spec (for FS/LS: 8, 16, 32, 64, and
1023 are defined; for HS: 64, 128, 512, and 1024 are defined).
For more detailed information on the USB2.0 peripheral, see the USB2.0 chapter in the AM38x Sitara
ARM Microprocessors (MPUs) Technical Reference Manual (literature number SPRUGX7). For detailed
information on USB board design and layout guidelines, see the USB 2.0 Board Design and Layout
Guidelines application report (literature number SPRAAR7)

PRODUCT PREVIEW
The device includes two USB2.0 modules which support the Universal Serial Bus Specification Revision
2.0. The following are some of the major USB features that are supported:
• USB 2.0 peripheral at high speed (HS: 480 Mbps) and full speed (FS: 12 Mbps)
• USB 2.0 host at HS, FS, and low speed (LS: 1.5 Mbps)
• Each endpoint (other than endpoint 0, control only) can support all transfer modes (control, bulk,
interrupt, and isochronous)
• Supports high-bandwidth ISO mode
• Supports 16 Transmit (TX) and 16 Receive (RX) endpoints including endpoint 0
• FIFO RAM - 32K endpoint - Programmable size
• Includes two integrated PHYs; requires a low-jitter 24-MHz source clock for its PLL
• RNDIS-like mode for terminating RNDIS-type protocols without using short-packet termination for
support of MSC applications.

Device Support
Development Support
TI offers an extensive line of development tools, including tools to evaluate the performance of the
processors, generate code, develop algorithm implementations, and fully integrate and debug software
and hardware modules. The tool's support documentation is electronically available within the Code
Composer Studio™ Integrated Development Environment (IDE).
The following products support development of AM389x MPU applications:
Software Development Tools: Code Composer Studio™ Integrated Development Environment (IDE):
including Editor C/C++/Assembly Code Generation, and Debug plus additional development tools
Scalable, Real-Time Foundation Software ( DSP/BIOS™), which provides the basic run-time target
software needed to support any Sitara ARM MPU application.
Hardware Development Tools: Extended Development System ( XDS™) Emulator
PRODUCT PREVIEW
For a complete listing of development-support tools for the AM389x Sitara™ ARM MPU platform, visit the
Texas Instruments website at www.ti.com. For information on pricing and availability, contact the nearest
TI field sales office or authorized distributor.
9.1.2
Device Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
MPUs and support tools. Each device has one of three prefixes: X, P, or null (no prefix) (e.g.,
XAM3894CYG). 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/tools (TMDS).
Device development evolutionary flow:
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.

TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, CYG), the temperature range (for example, blank is the default commercial
operating case temperature range), and the device speed range (for example, blank is the default
[1.0-GHz ARM]). Figure 9-1 provides a legend for reading the complete device name for any AM389x
device.
For device part numbers and further ordering information of AM389x devices in the CYG package type,
see 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 AM389x Sitara ARM
