Skype endpoints • Video Surveillance DVRs • IP Netcam • Digital Signage • Media Players and Adapters • Mobile Medical Imaging • Network Projectors • Home Audio and Video Equipment The device enables Original-Equipment Manufacturers (OEMs) and Original-Design Manufacturers (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 also combines programmable video and audio processing with a highly integrated peripheral set. The TMS320DM814x DaVinci video processors also present OEMs and ODMs with new levels of processor scalability and software reuse. An OEM or ODM that used the AM387x processors in a design and can make a similar product with added features could scale up to the pin-compatible and softwarecompatible TMS320DM814x processors from TI. The TMS320DM814x DaVinci video processors add a powerful C674x DSP core along with a video encoder and decoder to the hardware on the AM38x. Additionally, OEMs or ODMs that have used the AM387x or DM814x processors and find a need for a faster ARM and DSP core performance could scale up to the software-compatible AM389x or TMS320DM816x devices with higher core speeds. Programmability is provided by an ARM Cortex-A8 RISC CPU with Neon extension, TI C674x VLIW floating-point DSP core, and high-definition video and imaging coprocessors. The ARM lets developers keep control functions separate from A/V algorithms programmed on the DSP and coprocessors, thus reducing the complexity of the system software. The ARM Cortex-A8 32-Bit RISC Core with Neon floatingpoint extension includes: 32KB of Instruction cache; 32KB of Data cache; 512KB of L2 Cache; 48KB of Boot ROM; and 64KB of RAM. 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 • Dual Port Gigabit Ethernet MACs (10/100/1000 Mbps) [Ethernet Switch] with MII/RMII/GMII/RGMII and MDIO interface supporting IEEE 1588 Time-Stamping and Industrial Ethernet Protocols • Two USB ports with integrated 2.0 PHY • PCIe x1 GEN2 Compliant interface • Two 10-serializer McASP audio serial ports (with DIT mode) • Four quad-serilaizer McASP audio serial ports (with DIT mode) • One McBSP multichannel buffered serial port • Six UARTs with IrDA and CIR support • Four SPI serial interfaces • Three MMC/SD/SDIO serial interfaces • Four I2C master and slave interfaces • Parallel Camera Interface (CAM) • Up to 128 General-Purpose I/Os (GPIOs) 4 High-Performance System-on-Chip (SoC) Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com • • • • • • • • SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 Eight 32-bit general-purpose timers System watchdog timer Dual DDR2, and DDR3 SDRAM interfaces Flexible 8- or 16-bit asynchronous memory interface Two Controller Area Network (DCAN) modules Spin Lock Mailbox Serial Hard Disk Drive Interface (SATA 300) The TMS320DM814x DaVinci video processors also include a high-definition video and imaging coprocessor 2 (HDVICP2), and an SGX530 3D graphics engine to off-load many video and imaging processing tasks from the DSP core, making more DSP MIPS available for common video and imaging algorithms. Additionally, it has a complete set of development tools for both the ARM and DSP, which include C compilers, a DSP assembly optimizer to simplify programming and scheduling, and a Microsoft® Windows® debugger interface for visibility into source code execution. The C674x DSP core is the high-performance floating-point DSP generation in the TMS320C6000 DSP platform and is code-compatible with previous generation C64x Fixed-Point and C67x Floating-Point DSP generation. The C674x Floating-Point DSP processor uses 32KB of L1 program memory with EDC and 32KB of L1 data memory. Up to 32KB of L1P can be configured as program cache. The remaining memory is noncacheable no-wait-state program memory. Up to 32KB of L1D can be configured as data cache. The remaining memory is noncacheable no-wait-state data memory. The DSP has 256KB of L2 RAM with ECC, which can be defined as SRAM, L2 cache, or a combination of both. All C674x L3 and offchip memory accesses are routed through an MMU.

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 14 Device Overview Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com • • • • • • • • • • • 2.4.2 SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 Thumb-2 Instruction Set Jazelle RCT Acceleration CP14 Debug Coprocessor CP15 System Control Coprocessor NEON™ 64-/128-bit Hybrid SIMD Engine for Multimedia Enhanced VFPv3 Floating-Point Coprocessor Enhanced Memory Management Unit (MMU) Separate Level-1 Instruction and Data Caches Integrated Level-2 Cache 128-bit Interconnector-to-System Memories and Peripherals Embedded Trace Module (ETM). 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 which provides real-time trace capability for the ARM Cortex-A8. • Triggering facilities that provide trigger resources, which include address and data comparators, counter, and sequencers. The ARM Cortex-A8 trace port is not pinned out and is, instead, only 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 ETM, see Section 8.5.2, Trace. 2.4.3 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 7.5.1, ARM Cortex-A8 Interrupts. Note: For General-Purpose devices, the AINTC does not support the generation of FIQs to the ARM processor. 2.4.4 ARM Cortex-A8 PLL (PLL_ARM) The ARM Cortex-A8 subsystem contains an embedded PLL Controller (PLL_ARM) for generating the subsystem’s clocks from the DEV Clock input. For more details on the PLL_ARM, see Section 7.4, Clocking. 2.4.5 ARM MPU Interconnect The ARM Cortex-A8 processor is 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.

The two general-purpose register files (A and B) each contain 32 32-bit registers for a total of 64 registers. The general-purpose registers can be used for data or can be data address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bit data, 40bit data, and 64-bit data. Values larger than 32 bits, such as 40-bit-long or 64-bit-long values are stored in register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or 32 MSBs in the next upper register (which is always an odd-numbered register). The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one instruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L units perform a general set of arithmetic, logical, and branch functions. The .D units primarily load data from memory to the register file and store results from the register file into memory. The C674x CPU combines the performance of the C64x+ core with the floating-point capabilities of the C67x+ core. Each C674x .M unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, one 16 x 32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies with add/subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four 16 x 16 multiplies with add/subtract capabilities (including a complex multiply). There is also support for Galois field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and modems require complex multiplication. The complex multiply (CMPY) instruction takes four 16-bit inputs and produces a 32-bit real and a 32-bit imaginary output. There are also complex multiplies with rounding capability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. The 32 x 32 bit multiply instructions provide the extended precision necessary for high-precision algorithms on a variety of signed and unsigned 32-bit data types. The .L or (Arithmetic Logic Unit) now incorporates the ability to do parallel add/subtract operations on a pair of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data performing dual 16-bit add and subtracts in parallel. There are also saturated forms of these instructions. The C674x core enhances the .S unit in several ways. On the previous cores, dual 16-bit MIN2 and MAX2 comparisons were only available on the .L units. On the C674x core they are also available on the .S unit which increases the performance of algorithms that do searching and sorting. Finally, to increase data packing and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit/16-bit and dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations. Pack instructions return parallel results to output precision including saturation support. Other new features include: • SPLOOP - A small instruction buffer in the CPU that aids in creation of software pipelining loops where multiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code size associated with software pipelining. Furthermore, loops in the SPLOOP buffer are fully interruptible. • Compact Instructions - The native instruction size for the C6000 devices is 32 bits. Many common instructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C674x compiler can restrict the code to use certain registers in the register file. This compression is performed by the code generation tools. • Instruction Set Enhancement - As noted above, there are new instructions such as 32-bit multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field multiplication. • Exceptions Handling - Intended to aid the programmer in isolating bugs. The C674x CPU is able to detect and respond to exceptions, both from internally detected sources (such as illegal op-codes) and from system events (such as a watchdog time expiration). • Privilege - Defines user and supervisor modes of operation, allowing the operating system to give a basic level of protection to sensitive resources. Local memory is divided into multiple pages, each with read, write, and execute permissions.

This protects the ARM Cortex-A8 memory regions from accidental corruption by C674x code and allows for direct allocation of buffers in user space without the need for translation between ARM and DSP applications. In addition, accesses by the EDMA TC0 and TC1 may optionally be routed through the system MMU. This allows EDMA Channels 0 and 1 to be used by the DSP to perform transfers using only the known virtual addresses of the associated buffers. The MMU_CFG register in the Control Module is used to enable/disable use of the system MMU by the EDMA TCs.

The MUXED column in the tables also identifies all peripheral pin functions multiplexed on a pin, the pin control register (PINCNTLx) that controls which peripheral pin function is selected for that particular pin, and indicates the state driven on the peripheral input (logic 0, logic 1, or PIN level) when the peripheral pin function is not selected (that is, the de-selected input state [DSIS]), and the Multi-Muxed [MM] option for that peripheral pin function).

The sampled values are latched into the CONTROL_STATUS register, which is part of the Control Module. The BTMODE[15:11] values determine the following system boot settings: • RSTOUT_WD_OUT Control • GPMC CS0 Default Data Bus Width, Wait Enable, and Address/Data Multiplexing For additional details on BTMODE[15:11] pin functions, see Table 3-1, Boot Configuration Terminal Functions. The BTMODE[4:0] values determine the boot mode order according to Table 4-1, Boot Mode Order. The 1st boot mode listed for each BTMODE[4:0] configuration is executed as the primary boot mode. If the primary boot mode fails, the 2nd, 3rd, and 4th boot modes are executed in that order until a successful boot is completed. The BTMODE[7:5] pins are RESERVED and should be pulled down as indicated inTable 3-1, Boot Configuration Terminal Functions. When the EMAC bootmode is selected (see Table 4-1), the sampled value from BTMODE[9:8] pins are used to determine the Ethernet PHY Mode selection (see Table 4-7). When the XIP (MUX0), XIP (MUX1), XIP w/ WAiT (MUX0) or XIP w/ WAiT (MUX1) bootmode is selected (see Table 4-1), the sampled value from BTMODE[10] pin is used to select between GPMC pin muxing options shown in Table 4-2, XIP (on GPMC) Boot Options [Muxed or Non-Muxed].

TYPE UART0_RXD AH5 I UART0_TXD AG5 O Pin Multiplexing Control Device level pin multiplexing is controlled on a pin-by-pin basis by the MUXMODE bits of the PINCNTL1 – PINCNTL270 registers in the Control Module. Pin multiplexing selects which one of several peripheral pin functions controls the pin's I/O buffer output data values. Table 4-11 shows the peripheral pin functions associated with each MUXMODE setting for all multiplexed pins. The default pin multiplexing control for almost every pin is to select MUXMODE = 0x0, in which case the pin's I/O buffer is 3-stated. In most cases, the input from each pin is routed to all of the peripherals that share the pin, regardless of the MUXMODE setting. However, in some cases a constant "0" or "1" value is routed to the associated peripheral when its peripheral function is not selected to control any output pin. For more details on the De-Selected Input State (DSIS), see the "MUXED" columns of each Terminal Functions table (Section 3.2, Terminal Functions).

For unused input pins, the internal pull resistor should be enabled, or an external pull resistor should be used, to prevent floating inputs. Unless otherwise noted, all supply pins must always be connected to the correct voltage, even when their associated signal pins are unused. 4.5 4.5.1 DeBugging Considerations Pullup/Pulldown Resistors Proper board design should ensure that input pins to the TMS320DM814x DaVinci™ Digital Media Processsors 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. An external pullup/pulldown resistor needs to be used in the following situations: • Boot 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 boot configuration pins (listed in Table 3-1, Boot Configuration 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 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. 170 Device Configurations Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 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.

The PRCM interfaces with all the components on the device for power, clock, and reset management through power-control signals. The PRCM module inTiming Requirements for AUD_CLKINxtegrates enhanced features to allow the device to adapt energy consumption dynamically, according to changing application and performance requirements. The innovative hardware architecture allows a substantial reduction in leakage current. The PRCM module is composed of two main entities: • Power reset manager (PRM): Handles the power, reset, wake-up management, and system clock source control (oscillator) • Clock manager (CM): Handles the clock generation, distribution, and management. For more details on the PRCM, see the Power, Reset, and Clock Management (PRCM) Module chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 7.2 Power 7.2.1 Voltage and Power Domains Every Module within the device belongs to a Core Logic Voltage Domain, Memory Voltage Domain, and a Power Domain (see Table 7-1).

These domains define groups of Modules that share the same supply voltage for their core logic. Each Core Logic Voltage Domain is powered by a dedicated supply voltage rail. Table 7-2 shows the mapping between the Core Logic Voltage Domains and their associated supply pins.

Core Logic Voltage Domains and Supply Pin Associations CORE LOGIC VOLTAGE DOMAIN SUPPLY PIN NAME ARM_L CVDD_ARM CORE_L CVDD DSP_L CVDD_DSP HDVICP_L CVDD_HDVICP Note: A regulated supply voltage must be supplied to each Core Logic Voltage Domain at all times, regardless of the Core Logic Power Domain states. 7.2.1.2 Memory Voltage Domains The SRAM within each Device Module is assigned to one of four Memory Voltage Domains. The voltage of each Memory Voltage Domain is independently controlled by internal LDO regulators, which are supplied by the VDDA_1P8 pins. The voltage level output by each of these LDO regulators is controlled through software by programming the RAMLDO_CTRLx registers in the Control Module. The Memory Voltage Domain voltage must be programmed based on the Core Logic Voltage Domain voltage for that domain (that is, the corresponding Core Logic Voltage Domain for the ARM_M Voltage Domain is ARM_C, and so on). Table 7-3 shows the Memory Voltage Domain voltage requirements. Table 7-3. Memory Voltage Domain LDO Requirements 7.2.1.3 CORE LOGIC VOLTAGE DOMAIN VOLTAGE (V) MEMORY VOLTAGE DOMAIN VOLTAGE (V) 0.83 – 1.20 1.20 Power Domains The device contains six Power Domains which supply power to both the Core Logic and SRAM within their associated modules. Each Power Domain, except for the ALWAYS ON domain, has an internal power switch that can completely remove power from that domain. All power switches are turned "OFF" by default after reset, and software can individually turn them "ON/OFF" via Control Module registers. Note: All Modules within a Power Domain are unavailable when the domain is powered "OFF". For instructions on powering "ON/OFF" the Power domains, see the Power, Reset, and Clock Management (PRCM) Module chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 7.2.2 SmartReflex [Not Supported] The device contains SmartReflex modules that help to minimize power consumption on the Core Logic Voltage Domains by 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, I2C, SPI, or other methods. The following sections briefly describe the two major techniques employed by SmartReflex: Dynamic Voltage Frequency Scaling (DVFS) and Adaptive Voltage Scaling (AVS). 182 Power, Reset, Clocking, and Interrupts Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com 7.2.2.1 SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 Dynamic Voltage Frequency Scaling (DVFS) Each device Core Logic Voltage Domain can be run independently at one of several Operating Performance Points (OPPs). An OPP for a specific Core Logic Voltage Domain is defined by: (1) maximum frequencies of operation for Modules within the Domain and (2) an associated supply voltage range. Trading off power versus performance, OPPs with lower maximum frequencies also have lower voltage ranges for power savings. The OPP for a domain can be changed in real-time without requiring a reset. This feature is called Dynamic Voltage Frequency Scaling (DVFS). Table 7-4 contains a list of voltage ranges and maximum module frequencies for the OPPs of each Core Logic Voltage Domain. Table 7-4.

Only DM814x SR3.0 devices support a DSP Frequency of 750-MHz. For more details on device silicon revisions, see Figure 9-1, Device Nomenclature. Although the OPP for each Core Logic Voltage Domain is independently selectable, not all combinations of OPPs are supported. Table 7-5 marks the supported ARM, DSP, and HDVICP2 OPPs for a given CORE OPP. Table 7-5. Supported OPP Combinations (1) (2) ARM CORE OPP166 OPP166 X OPP120 X OPP100 (1) (2) OPP120 DSP OPP100 OPP166 OPP120 HDVICP2 OPP100 X X X X X OPP166 OPP120 OPP100 X X X X X X X X "X" denotes supported combinations. The maximum voltage differences between CVDD and any other CVDD_x voltage domain must be < 150 mV. 7.2.2.2 Adaptive Voltage Scaling [Not Supported] As mentioned in Section 7.2.2.1, Dynamic Voltage Frequency Scaling (DVFS) above, every OPP has an associated voltage range. Based on the silicon process, temperature, and chosen OPP, the SmartReflex modules guide software in adjusting the Core Logic Voltage Domain supply voltages within these ranges. 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. 7.2.3 Memory Power Management To reduce SRAM leakage, many SRAM blocks can be switched from ACTIVE mode to SHUTDOWN mode. When SRAM is put in SHUTDOWN mode, the voltage supplied to it is automatically removed and all data in that SRAM is lost. Power, Reset, Clocking, and Interrupts Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 Copyright © 2011–2013, Texas Instruments Incorporated 183 TMS320DM8148, TMS320DM8147 SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 www.ti.com All SRAM located in a switchable power domain (all domains except ALWAYS_ON) automatically enters SHUTDOWN mode whenever its associated power domain goes into the "OFF" state. The SRAM returns to the ACTIVE state when the corresponding Power Domain returns to the "ON" state. In addition, the following SRAM within the ALWAYS_ON Power Domain can also be independently put into SHUTDOWN by programming the x_MEM_PWRDN registers in the Control Module: • Media Controller SRAM • OCMC SRAM For detailed instructions on powering up/down the various device SRAM, see the Control Module chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 7.2.4 SERDES_CLKP and SERDES_CLKN LDO The SERDES_CLKP and SERDES_CLKN input buffers are powered by an internal LDO which is programmed through the REFCLK_LJCBLDO_CTRL register in the Control Module. For more information on programming the SERDES_CLKP and SERDES_CLKN LDO, see PCI Express (PCIe) Module and Serial ATA (SATA) Controller chapters of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 7.2.5 Dual Voltage I/Os The device supports dual voltages on some of its I/Os. These I/Os are partitioned into the following groups, and each group has its own dedicated supply pins: DVDD, DVDD_GPMC, DVDD_C, and DVDD_SD. The supply voltage for each group can be independently powered with either 1.8 V or 3.3 V. For the mapping between pins and power groups, see Section 3.2, Terminal Functions of the datasheet. In addition, the I/O voltage on each DDR interface is independently selectable between either 1.5 V or 1.8 V to support various DDR device types. The I/O supplies for each DDR interface are separate and isolated to allow populating different memory types on each interface. 7.2.6 I/O Power-Down Modes On the device, there are power-down modes available for the following PHYs: • Video DAC • DDR • USB • HDMI • PCIE • SATA When a PHY controller is in a power domain that is to be turned "OFF", software must configure the corresponding PHY into power-down mode, prior to putting the power domain in the "OFF" state. 184 Power, Reset, Clocking, and Interrupts Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com 7.2.7 SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 Standby Mode The device supports Low-Power Standby Mode as described below. Standby Mode is defined as a state in which: • All switchable power domains are in "OFF" state • The ARM Cortex-A8 is executing an IDLE loop at its lowest frequency of operation • All functional blocks not needed for a given application are clock gated For detailed instructions on entering and exiting from Standby Mode see the Power, Reset, and Clock Management (PRCM) Module chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 7.2.8 Supply Sequencing The device power supplies are organized into four Supply Sequencing Groups: 1. All CVDD supplies (CVDD, CVDD_x) 2. All 1.5-/1.8-V DVDD_DDR[x] Supplies (1.5 V for DDR3, 1.8 V for DDR2) 3. All 1.8-V Supplies (DVDD_x, DVDD_M, VDDA_x_1P8, VDDA_1P8) 4. All 3.3-V Supplies (DVDD, DVDD_x, DVDD_C, VDDA_x_3P3) To ensure proper device operation, a specific power-up and power-down sequence must be followed. Some TI power-supply devices include features that facilitate these power sequencing requirements — for example, TI’s TPS659113 integrated PMIC.

For more detailed information on the actual power supply names and their descriptions, see Table 3-49, Supply Voltages Terminal Functions. 7.2.8.1 Power-Up Sequence For proper device operation, the following power-up sequence in Table 7-6 and must be followed.

The minimum recommendation is a ferrite bead along with at least one capacitor on the device side of the bead. An additional recommendation is to add one capacitor just before the bead to form a Pi filter. The filter needs to be as close as possible to the device pin, with the device side capacitor being the most important component to be close to the device pin. PLL pins close together can be combined on the same supply, but analog pins should all have their own filters. PLL pins farther away from each other may need their own filtered supply. 7.2.9.2 Digital Recommended capacitors for power supply decoupling are all 0.1uF in the smallest body size that can be used. Capacitors are more effective in the smallest physical size to limit lead inductance. For example, 0201 sized capacitors are better than 0402 sized capacitors, and so on. TI recommends using capacitors no larger than 0402. Place at least one capacitor for every two power pins. For those power pins that have only one pin, a capacitor is still required. Place one bulk (10 uF or larger) capacitor for every 10 or so power pins as closely as possible to the chip. These larger caps do not need to be under the chip footprint.

Table 7-8 lists these reset types, along with the reset initiator, and the effects of each reset on the device. Table 7-8.

While POR and/or RESET is asserted, the RSTOUT_WD_OUT pin is 3-stated and the internal pull resistor is disabled; therefore, an external pullup/pulldown can be used to set the state of this pin (high/low) while POR and/or RESET is asserted. For more detailed information on external PUs/PDs, see Section 4.5.1, Pullup/Pulldown Resistors. EMAC Switch is NOT reset when the ISO_CONTROL bit in the RESET_ISO Control Module register is set to "1". 7.3.2 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, and the EMAC Switch. POR is also referred to as a cold reset since it is required to be asserted when the device 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 DEV_CLKIN, AUX_CLKIN, and 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 sources are stable, the POR pin must remain asserted (low) [see Section 7.3.18, Reset Electrical Data/Timing]. Within the low period of the POR pin, the following happens: (a) All pins except Emulation pins enter a Hi-Z mode and the associated pulls, if applicable, will be enabled. (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 de-asserted (driven high). When the POR pin is de-asserted (high): (a) The BTMODE[15:0] pins are latched. (b) Reset to the ARM Cortex-A8 and Modules without a local processor is de-asserted. (c) RSTOUT_WD_OUT is briefly asserted if BTMODE[11] was latched as "0". (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 Boot ROM.

This resets everything in the device, except for the Test and Emulation logic, and the EMAC Switch (optional). 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)[see Section 7.3.18, Reset Electrical Data/Timing]. Within the low period of the RESET pin, the following happens: (a) All pins, except Test and Emulation pins, enter a Hi-Z mode and the associated pulls, if applicable, will be enabled. (b) The PRCM asserts reset to all modules within the device, except for the Test and Emulation logic, EMAC Switch (optional), PLL, and Clock configuration. 3. The RESET pin may now be de-asserted (driven high). When the RESET pin is de-asserted (high): (a) The BTMODE[15:0] pins are latched. (b) Reset to the ARM Cortex-A8 and modules without a local processor is de-asserted, with the exception of Test and Emulation logic, EMAC Switch (optional), PLL, and Clock configuration. (c) RSTOUT_WD_OUT is asserted [see Section 7.3.18, Reset Electrical Data/Timing], if BTMODE[11] was latched as "0". (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 Boot ROM. 7.3.4 Emulation Warm Reset An Emulation Warm Reset is activated by the on-chip Emulation Module and has the same effect and requirements as an External Warm Reset (RESET), with the following exceptions: • BTMODE[15:0] pins are not re-latched • RSTOUT_WD_OUT is not 3-stated and is actively driven based on the value previously latched on the BTMODE[11] pin. 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: Target -> Reset -> System Reset. 7.3.5 Watchdog Reset A Watchdog Reset is initiated when the Watchdog Timer counter reaches zero and has the same effect and requirements as an External Warm Reset (RESET pin), with the following exceptions: • BTMODE[15:0] pins are not re-latched • RSTOUT_WD_OUT is not 3-stated and is actively driven based on the value previously latched on the BTMODE[11] pin. In addition, a Watchdog Reset always results in RSTOUT_WD_OUT being asserted, regardless of whether the BTMODE[11] pin was latched as "0" or "1". 7.3.6 Software Global Cold Reset A Software Global Cold Reset is initiated under software control and has the same effect and requirements as a POR Reset, with the following exceptions: • BTMODE[15:0] pins are not re-latched and EMAC Switch (optional) is not reset • RSTOUT_WD_OUT is not 3-stated and is actively driven based on the value previously latched on the BTMODE[11] pin. 190 Power, Reset, Clocking, and Interrupts Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 Software initiates a Software Global Cold Reset by writing a "1" to the RST_GLOBAL_COLD_SW bit in the PRM_RSTCTRL register in the PRCM.

The only effect a Test Reset has is to reset the Test and Emulation Logic. 7.3.9 Local Reset The Local Reset for various Modules within the device is controlled by programming the PRCM and/or the Peripheral Module’s internal registers. Only the associated Module is reset when a Local Reset is asserted, leaving the rest of the device unaffected. For more details on Peripheral Local Resets, see the Reset Management section of the Power, Reset, and Clock Management (PRCM) Module chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 7.3.10 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 pin) 4. Emulation Warm Resets 5. Watchdog Reset 6. Software Global Cold/Warm Resets 7.3.11 Reset Status Register The Reset Status Register (PRM_RSTST) contains information about the last reset that occurred in the system.

This means that the PCI Express Subsystem can be reset without resetting the rest of the device. When the devcie 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. 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 will generate 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, will also reset the PCIE Subsystem. Therefore, the PCIE peripheral should issue a Hot Reset to all downstream devices and reenumerate the bus upon coming out of reset. For more detailed information on reset isolation procedures, see the PCIe Reset Isolation section of the Power, Reset, and Clock Management (PRCM) Module chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 7.3.13 EMAC Switch Reset Isolation The device supports reset isolation for the Ethernet Switch (EMAC Switch). This allows the device to undergo all resets listed in Section 7.3.1, System-Level Reset Sources, with the exception of POR Reset, without disrupting the Ethernet Switch or the traffic being routed through the switch during the reset condition. The following reset types can optionally provide an EMAC Switch reset isolation by setting the ISO_CONTROL bit in the RESET_ISO Control Module register to a "1": • External Warm Reset • Emulation Warm Reset • Watchdog Reset • Software Global Cold Reset • Software Global Warm Reset When one of above resets occurs and the Ethernet Switch (EMAC Switch) is programmed to be isolated: • The switch function of the EMAC Switch and the PLL embedded in the SATA SERDES Module (which provides the reference clocks to the EMAC Switch) will not be reset. • Several Control Module registers are not reset. For more details, see the description of the RESET_ISO register in the Control Module chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). • The pin multiplexing of some of the EMAC Switch pins is unaffected. For more details, see the description of the RESET_ISO register in the Control Module chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). The EMAC Switch is always reset when: • One of the above resets occurs and the Ethernet Switch is programmed to be “not isolated” • A POR Reset occurs 192 Power, Reset, Clocking, and Interrupts Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 7.3.14 RSTOUT_WD_OUT Pin The RSTOUT_WD_OUT pin reflects device reset status and is de-asserted (high) when the device is out reset. This output will always be asserted when a Watchdog Timer reset (Watchdog Reset) occurs. In addition, this output is always 3-stated and the internal pull resistor is disabled on this pin while POR and/or RESET is asserted; therefore, an external pullup/pulldown can be used to set the state of this pin (high/low) while POR and/or RESET is asserted. For more detailed information on external PUs/PDs, see Section 4.5.1, Pullup/Pulldown Resistors. If the BTMODE[11] pin is latched as a "0" at the rising edge of POR or RESET, then RSTOUT_WD_OUT is also asserted when any of the below resets occur: • Power-On Reset (asserted after the BTMODE[11] pin is latched) • External Warm Reset (asserted after the BTMODE[11] pin is latched) • Emulation Warm Reset • Software Global Cold/Warm Reset The RSTOUT_WD_OUT pin remains asserted until the PRCM releases the host ARM Cortex-A8 processor for reset. 7.3.15 Effect of Reset on Emulation and Trace The device Emulation and Trace Logic will only be reset by the following sources: • Power-On Reset • Software Global Cold Reset • Test Reset Other than these three reset types, none of the other resets will affect the Emulation and Trace Logic. However, the multiplexing of the EMU[4:2] pins is reset by all system reset types except Test Reset. 7.3.16 Reset During Power Domain Switching Each Power Domain has a dedicated Warm Reset and Cold Reset. Warm Reset for a Power Domain is asserted under either of the following two conditions: 1. An External Warm Reset, Emulation Warm Reset, or Software Global Warm Reset occurs 2. When that Power Domain switches from the "ON" state to the "OFF" state Cold Reset for a Power Domain is asserted under either of the following two conditions: 1. Power-On Reset or Software Global Cold Reset occurs 2. When that Power Domain switches from the "OFF" state to the "ON" state 7.3.17 Pin Behaviors at Reset When any reset, other than Test Reset, (all described in Section 7.3.1, System-Level Reset Sources) is asserted, all device I/O pins are reset into a Hi-Z state except for: • Emulation Pins. These pins are only put into a Hi-Z state when Test Reset (TRST) is asserted. • EMAC Switch Pins. These pins are always put into a Hi-Z state during Power-On Reset. However, some EMAC Switch pins will not be put into a Hi-Z state during the other reset modes when the ISO_CONTROL bit in the RESET_ISO register of the Control Module is programmed as a "1". For more details, see the description of the RESET_ISO register in the Control Module chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). • RSTOUT_WD_OUT Pin during any reset types except for POR and RESET.

These pins are 3-stated during reset. However, these pins are then driven to the same value as their internal pull resistor reset value when reset is released (For the direction of the internal pull during reset, see the DDR[0]/[1] Terminal Functions tables in the Section 3.2.4, DDR2/DDR3 Memory Controller of this document). In addition, the PINCNTL registers, which control pin multiplexing, enabling the IPUs/IPDs, and enabling the receiver, are reset to their default state. Again, enabling the EMAC Switch reset isolation prevents some PINCNTL registers from being reset. For details on EMAC Switch reset isolation, see the descriptions of the RESET_ISO register and the PINCNTL registers in the Control Module chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). Internal pull-up/down (IPU/IPD) resistors are enabled during and immediately after reset as described in Section 3.2, Terminal Functions of this document. NOTE Upon coming out of reset, the ARM Cortex-A8 starts executing code from the internal Boot ROM. The Boot ROM code modifies the PINCNTLx registers to configure the associated pins for the chosen primary and backup Bootmodes. For more details on the Boot ROM effects on pin multiplexing, see the ROM Code Memory and Peripheral Booting and Control Module chapters of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 7.3.18 Reset Electrical Data/Timing Table 7-9.

The Device (DEV) clock is used to generate the majority of the internal reference clocks, while the Auxiliary (AUX) clock can optionally be used as a source for the Audio and/or Video PLLs. The DEV and AUX clocks can be sourced in two ways: 1. Using an external crystal in conjunction with the internal oscillator or 2. Using an external 1.8-V LVCMOS-compatible clock input Note: The external crystals used with the internal oscillators must operate in fundamental parallel resonant mode only. There is no overtone support. The DEV Clock should in most cases be 20 MHz. However, it can optionally range anywhere from 20 - 30 MHz if the following are true: • The DEV Clock is not used to source the SATA reference clock • A precise 32768-Hz clock is not needed for Real-Time Clock functionality • If the boot mode is FAST XIP The AUX Clock is optional and can range from 20-30 MHz. AUX Clock can be used to source the Audio and/or Video PLLs when a very precise audio or video frequency is required. 7.4.1.1 Using the Internal Oscillators When the internal oscillators are used to generate the DEV and AUX clocks, external crystals are required to be connected across the DEVOSC or AUXOSC oscillator MXI and MXO pins, along with two load capacitors (see Figure 7-7 and Figure 7-8). The external crystal load capacitors should also be connected to the associated oscillator ground pin (VSSA_DEVOSC or VSSA_AUXOSC). The capacitors should not be connected to board ground (VSS).

The clock is required to be AC coupled to the SERDES_CLKP and SERDES_CLKN device pins according to the specifications in Table 7-13. Both the clock source and the coupling capacitors should be placed physically as close to the processor as possible.

The PLLs must be configured not to exceed any of the constraints placed on these values shown in Table 7-23 through Table 7-25. Care must be taken to stay within these limits when selecting external clock input frequencies, internal divider values, and PLL multiply ratios. In addition, limits shown in these tables may be further restricted by the clock frequency limitations of the device modules using these clocks.

The ARM Cortex-A8, C674x DSP, and Media Controller are capable of servicing these interrupts. However, the C674x DSP require additional system-level interrupt multiplexors to receive their interrupts. The following sections list the device interrupt mapping and multiplexing schemes. 7.5.1 ARM Cortex-A8 Interrupts The ARM Cortex-A8 Interrupt Controller (AINTC) is responsible for prioritizing all service requests from the System peripherals and generating either IRQs or FIQs to the Cortex-A8. The AINTC has the capability to handle up to 128 requests, and the priority of the interrupt inputs are programmable. Table 7-28 lists the interrupt sources for the AINTC. Note: For General-Purpose devices, the AINTC does not support the generation of FIQs to the ARM processor.

For output timing analysis, the tester pin electronics and its transmission line effects must be taken into account. A transmission line with a delay of 2 ns can be used to produce the desired transmission line effect. The transmission line is intended as a load only. It is not necessary to add or subtract the transmission line delay (2 ns) from the data sheet timings. Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the device pin. Figure 8-1. Test Load Circuit for AC Timing Measurements The load capacitance value stated is only for characterization and measurement of AC timing signals. This load capacitance value does not indicate the maximum load the device is capable of driving. 8.1.1 1.8-V and 3.3-V Signal Transition Levels All input and output timing parameters are referenced to Vref for both "0" and "1" logic levels. For 3.3-V I/O, Vref = 1.5 V. For 1.8-V I/O, Vref = 0.9 V. Vref Figure 8-2. Input and Output Voltage Reference Levels for AC Timing Measurements All rise and fall transition timing parameters are referenced to VIL MAX and VIH MIN for input clocks, VOL MAX and VOH MIN for output clocks.

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. 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. 222 Peripheral Information and Timings Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com 8.3 SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 Controller Area Network Interface (DCAN) The device provides two DCAN interfaces for supporting distributed realtime control with a high level of security.

These data transfers include cache servicing, non-cacheable memory accesses, userprogrammed data transfers, and host accesses. 8.4.1 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 defaul EDMA synchronization event as shown in Table 8-3. 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, see the Enhanced Direct Memory Access Controller chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8).

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. 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) 8.5.2 Trace The device supports Trace at the Cortex™-A8, C674x, 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). 8.5.3 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 boundary scan functionality of the device. 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 internal emulation logic of the device 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) 232 Peripheral Information and Timings Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com 8.5.3.1 SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 JTAG ID (JTAGID) Register Description Table 8-7.

The EMAC SW contains a 3-port gigabit switch, where one port is internally connected and the other two ports are brought out externally. Each of the external EMAC ports supports 10Base-T (10 Mbits/second [Mbps]), and 100BaseTX (100 Mbps), in either half- or full-duplex mode, and 1000BaseT (1000 Mbps) in full-duplex mode. The EMAC SW controls the flow of packet data from the device to the external PHYs. The EMAC0/1 ports on the device support four interface modes: Media Independent Interface (MII), Gigabit Media Independent Interface (GMII), Reduced Media Independent Interface (RMII) and Reduced Gigabit Media Independent Interface (RGMII). In addition, 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 SW 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 SW 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 SW will intentionally generate an incorrect checksum by inverting the frame CRC, so that the transmitted frame will be detected as an error by the network. In addition, the EMAC SW 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. In networking systems, packet transmission and reception are critical tasks. The communications port programming interface (CPPI) protocol maximizes the efficiency of interaction between the host software and communications modules. The CPPI block contains 2048 words of 32-bit buffer descriptor memory that holds up to 512 buffer descriptors.

The MDIO module implements the 802.3 serial management interface to interrogate and control Ethernet PHYs using a shared two-wire bus. Host software uses the MDIO module to configure the autonegotiation parameters of each PHY attached to the EMAC SW, retrieve the negotiation results, and configure required parameters in the EMAC SW 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 3PSW Ethernet Subsystem chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 8.6.3.1 MDIO Peripheral Register Descriptions Table 8-27.

In addition, the GPIO peripheral can produce CPU interrupts in different interrupt modes. The GPIO peripheral provides generic connections to external devices. or outputs. output pin. an internal generation The device contains four GPIO modules and each GPIO module is made up of 32 identical channels. The device GPIO peripheral supports the following: • Up to 128 1.8-V/3.3-V GPIO pins, GP0[0:31], GP1[0:31], GP2[0:31], and GP3[0:31] (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 transitions and/or signal levels). • Synchronous interrupt requests from each channel are processed by four identical interrupt generation sub-modules to be used independently by the ARM, DSP, or Media Controller. Interrupts can be triggered by rising and/or falling edge, specified for each interrupt-capable GPIO signal. • Shared registers can be accessed through "Set and Clear" protocol. Software writes 1 to corresponding bit position or positions to set or to clear the GPIO signal. 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. • 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.

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 8-37, HDMI Interface High-Level Schematic. The TMDS channels are high-speed differential pairs and, therefore, require the most care in layout. Specifications for TMDS layout are below. Figure 8-37 shows the HDMI interface schematic. The specific pin numbers can be obtained from Table 315, HDMI Terminal Functions.

HDMI Interface High-Level Schematic 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 8-40 shows the routing specifications for the TMDS signals. Table 8-40.

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 3.3V supply. 8.9.1.4 HDMI ESD Protection Device (Required) Interfaces that connect to a cable such as HDMI generally require more ESD protection than can be built into the outputs of the processor. 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.

In Normal mode, the device’s internal video amplifier is used. In TVOUT Bypass mode, the internal video amplifier is bypassed and an external amplifier is required. Figure 8-41 shows a typical circuit that permits connecting the analog video output from the device to standard 75-Ω impedance video systems in Normal mode. Figure 8-42 shows a typical circuit that permits connecting the analog video output from the device to standard 75-Ω impedance video systems in TVOUT Bypass mode.

Note: An amplifier with an integrated reconstruction filter can alternatively be used instead of a discrete reconstruction filter. AC coupling capacitor (optional) Figure 8-42. TV Output (TVOUT Bypass Mode) During board design, the onboard traces and parasitics must be matched for the channel. The video DAC output pins (TV_OUTx/TV_VFBx) are very high-frequency analog signals and must be routed with extreme care. As a result, the paths of these signals must be as short as possible, and as isolated as possible from other interfering signals. In TVOUT Bypass mode, the load resistor and amplifier/buffer should be placed as close as possible to the TV_VFBx pins. Other layout guidelines include: • Take special care to bypass the VDDA_VDAC_1P8 power supply pin with a capacitor. For more information, see Section 7.2.9, Power-Supply Decoupling. • In TVOUT Bypass mode, place the RLOAD resistor as close as possible to the Reconstruction Filter and Amplifier. In addition, place the 75-Ω resistor as close as possible (< 0.5 ") to the Amplifier/buffer output pin. To maintain a high-quality video signal, the onboard traces after the 75-Ω resistor should have a characteristic impedance of 75 Ω (± 20%). • In Normal mode, TV_VFBx is the most sensitive pin in the TV out system. The ROUT resistor should be placed as close as possible to the device pins. To maintain a high-quality video signal, the onboard traces leading to the TV_OUTx pin should have a characteristic impedance of 75 Ω (± 20%) starting from the closest possible place to the device pin output. • 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 (that is, Y and C for S-Video output should match each other). 278 Peripheral Information and Timings Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 For additional Video DAC Design guidelines, see the High Definition Video Processing Subsystem chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8).

A Fast-mode I2C-bus™ device can be used in a Standard-mode I2C-bus system, but the requirement tsu(SDA-SCLH)≥ 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr max + tsu(SDA-SCLH)= 1000 + 250 = 1250 ns (according to the Standard-mode I2C-Bus Specification) before the SCL line is released. A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the undefined region of the falling edge of SCL. The maximum th(SDA-SCLL) has only to be met if the device does not stretch the low period [tw(SCLL)] of the SCL signal. Cb = total capacitance of one bus line in pF.

DDR2/DDR3 Memory Controller Clock Timing 8.13.4.1 DDR2 Routing Specifications 8.13.4.1.1 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 the Understanding TI’s PCB Routing Rule-Based DDR Timing Specification Application Report (Literature Number: SPRAAV0). 8.13.4.1.1.1 DDR2 Interface Schematic Figure 8-47 shows the DDR2 interface schematic for a x32 DDR2 memory system. In Figure 8-48 the x16 DDR2 system schematic is identical except that the high-word DDR2 device is deleted. When not using all or part of a DDR2 interface, the proper method of handling the unused pins is to tie off the DDR[x]_DQS[n] pins to the corresponding DVDD_DDR[x] supply via a 1k-Ω resistor and pulling the DDR[x]_DQS[n] pins 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. The DVDD_DDR[x] and VREFSSTL_DDR[x] power supply pins need to be connected to their respective power supplies even if DDR[x] is not being used. All other DDR interface pins can be left unconnected. Note that the supported modes for use of the DDR EMIF are 32-bits wide, 16-bits wide, or not used.

The dimensions for this figure are defined in Table 8-57. The placement does not restrict the side of the PCB on which the devices are mounted.

The DDR2 keepout region is defined for this purpose and is shown in Figure 8-50. The size of this region varies with the placement and DDR routing. Additional clearances required for the keepout region are shown in Table 8-57. A1 DDR2 Device A1 A1 DDR2 Controller A1 Figure 8-50. 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 1.8-V 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. 8.13.4.1.1.6 Bulk Bypass Capacitors Bulk bypass capacitors are required for moderate speed bypassing of the DDR2 and other circuitry. Table 8-58 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.

Serial terminators may be used on data lines to reduce EMI risk; however, serial terminations are the only type permitted. ODTs are integrated on the data byte net classes.

VREF is intended to be half the DDR2 power supply voltage and should be created using a resistive divider as shown in Figure 8-48. Other methods of creating VREF are not recommended.

VREF Nominal Max Trace width is 20 mils VREF Bypass Capacitor A1 + DDR2 Device A1 + DDR2 Controller Neck down to minimum in BGA escape regions is acceptable.

A 16-bit DDR memory system has two sets of data net classes; one for data byte 0, and one for data byte 1, each with an associated DQS (2 DQSs) per DDR EMIF used. A 32-bit DDR memory system has four sets of data net classes; one each for data bytes 0 through 3, and each associated with a DQS (4 DQSs) per DDR EMIF used. There is no need, and it is not recommended, to skew match across data bytes; that is, from DQS0 and data byte 0 to DQS1 and data byte 1. DQs from other DQS domains are considered other DDR2 trace. DQs from other data bytes are considered other DDR2 trace. DQLM is the longest Manhattan distance of each of the DQS and DQ net classes. 8.13.4.2 DDR3 Routing Specifications 8.13.4.2.1 DDR3 versus DDR2 This specification only covers PCB designs that utilize DDR3 memory. PCB designs using other types of DDR memory should follow the specification appropriate for that type of memory. It is currently not possible to design a single PCB that supports multiple types of DDR memory. 8.13.4.2.2 DDR3 EMIFs A processor may contain more than one EMIF. This specification covers only one EMIF and needs to be implemented for each additional EMIF. Requirements are identical between the EMIFs, however, the PCB layouts will most likely be different. 8.13.4.2.3 DDR3 Device Combinations Since there are several possible combinations of device counts and single- or dual-side mounting, Table 8-65 summarizes the supported device configurations.

General connectivity is straightforward and very similar. 16-bit DDR devices look like two 8-bit devices. Figure 8-54 and Figure 8-55 show the schematic connections for 32-bit interfaces using x16 and x8 devices. Note that a 16-bit wide interface schematic is practically identical to the 32-bit interface; only the high-word DDR memories are removed. When not using all or part of a DDR3 interface, the proper method of handling the unused pins is to tie off the DDR[x]_DQS[n] pins to the corresponding DVDD_DDR[x] supply via a 1-kΩ resistor and pulling the DDR[x]_DQS[n] pins to ground via a 1k-Ω resistor. This needs to be done for each byte not used. Although these signals have internal pullups and pulldowns, external pullups and pulldowns provide additional protection against external electrical noise causing activity on the signals.Also, include the 50-Ω pulldown for DDR[x]_VTP. The DVDD_DDR[x] and VREFSSTL_DDR[x] power supply pins need to be connected to their respective power supplies even if DDR[x] is not being used. All other DDR interface pins can be left unconnected. Note that the supported modes for use of the DDR EMIF are 32 bits wide, 16 bits wide, or not used.

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.

It is very difficult to add bypass capacitors once the board has been routed and significant rework may be required to meet the high-speed bypass capacitor requirements in Section 8.13.4.2.4.6, High-Speed Bypass Capacitors if the proper planning is not done. A particular challenge to placing bypass capacitors in congested areas is fitting the required vias. It is suggested that each pair of vias support two bypass capacitors by mounting one capacitor on the top of the board and other on the bottom. Do not share vias between capacitors mounted on the same side of the PCB. Another suggestion is to line up the vias for the bypass capacitors for the processor in rows forming channels to allow the signals to escape.

Non-DDR3 signals allowed within DDR3 keepout region provided they are separated from DDR3 routing layers by a ground plane. If a device has more than one DDR controller, the signals from the other controller(s) are considered non-DDR3 and should be separated by this specification. 8.13.4.2.4.4 DDR3 Keepout Region The region of the PCB used for DDR3 circuitry must be isolated from other signals. The DDR3 keepout region is defined for this purpose and is shown in Figure 8-57. The size of this region varies with the placement and DDR routing. Additional clearances required for the keepout region are shown in Table 870. 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 if there is more than one DDR controller, the signals from each controller need to be separated from each other by the specification in Table 8-70, item 5. Each DDR controller should have its own DDR keepout region.

It is particularly important to minimize the parasitic series inductance of the HS bypass capacitors, processor/DDR power, and processor/DDR ground connections. Table 8-72 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.

Care should be taken to minimize the layer transitions during routing. If a layer transition is necessary, it is better to transition to a layer using the same reference plane. If this cannot be accommodated, ensure there is a nearby path to allow the return currents to transition between reference planes. Transitions from power reference planes to ground reference planes must go through a bypass capacitor. Transition between different ground references or DVDD_DDR planes can go through a connecting via. As many of these return current bypass capacitors or vias should be used as possible. The goal is to minimize the size of the return current loops. Generally, this type of situation happens where signals must transition from horizontal to vertical routing and vice-versa. 8.13.4.2.4.7 Net Classes Table 8-73 lists the clock net classes for the DDR3 interface. Table 8-74 lists the signal net classes, and associated clock net classes, for signals in the DDR3 interface. These net classes are used for the termination and routing rules that follow. Table 8-73.

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. 8.13.4.2.4.9 VREFSSTL_DDR Routing VREFSSTL_DDR (VREF) is used as a reference by the input buffers of the DDR3 memories as well as the processor. VREF is intended to be half the DDR3 power supply voltage and is typically generated with the DDR3 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. 310 Peripheral Information and Timings Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 8.13.4.2.4.10 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. 8.13.4.2.4.11 CK and ADDR_CTRL Topologies and Routing Definition The CK and ADDR_CTRL net classes are routed similarly and are length matched to minimize skew between them. CK is a bit more complicated because it runs at a higher transition rate and is differential. The following subsections show the topology and routing for various DDR3 configurations for CK and ADDR_CTRL. Only the components shown in the topologies are allowed. Items such as test points and additional terminations are specifically disallowed. The figures in the following subsections define the terms for the routing specification detailed in Table 8-75. Care should be taken to minimize layer transitions during routing. If a layer transition is necessary, it is better to transition to a layer using the same reference plane. If this cannot be accommodated, ensure there are nearby ground vias to allow the return currents to transition between reference planes if both reference planes are ground or DVDD_DDR. Ensure there are nearby bypass capacitors to allow the return currents to transition between reference planes if one of the reference planes is ground. The goal is to minimize the size of the return current loops. 8.13.4.2.4.11.1 Four DDR3 Devices Four DDR3 devices are supported on the DDR EMIF consisting of four x8 DDR3 devices arranged as one bank (CS).

The only way to practically match lengths on a PCB is to lengthen the shorter traces up to the length of the longest net in the net class and its associated clock. A metric to establish this maximum length is Manhattan distance. The Manhattan distance between two points on a PCB is the length between the points when connecting them only with horizontal or vertical segments. A reasonable trace route length is to within a percentage of its Manhattan distance. CACLM is defined as Clock Address Control Longest Manhattan distance. Given the clock and address pin locations on the processor and the DDR3 memories, the maximum possible Manhattan distance can be determined given the placement. Figure 8-78 and Figure 8-79 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 8-75. 320 Peripheral Information and Timings Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 (A) A1 A8 CACLMY CACLMX A8 (A) A8 (A) A8 (A) A8 (A) Rtt A3 = A.

CK spacing set to ensure proper differential impedance. The most important thing to do is control the impedance so inadvertent impedance mismatches are not created. Generally speaking, center-to-center spacing should be either 2w or slightly larger than 2w to achieve a differential impedance equal to twice the singleended impedance, Zo. Source termination (series resistor at driver) is specifically not allowed. Termination values should be uniform across the net class. 8.13.4.2.4.13.2 DQS and DQ Routing Specification Skew within the DQS and DQ/DM net classes directly reduces setup and hold margin and thus this skew must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter traces up to the length of the longest net in the net class and its associated clock. As with CK and ADDR_CTRL, a reasonable trace route length is to within a percentage of its Manhattan distance. DQLMn is defined as DQ Longest Manhattan distance n, where n is the byte number. For a 32-bit interface, there are four DQLMs, DQLM0–DQLM3. Likewise, for a 16-bit interface, there are two DQLMs, DQLM0–DQLM1. NOTE It is not required, nor is it recommended, to match the lengths across all bytes. Length matching is only required within each byte. 322 Peripheral Information and Timings Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 Given the DQS and DQ/DM pin locations on the processor and the DDR3 memories, the maximum possible Manhattan distance can be determined given the placement. Figure 8-80 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 8-76.

There are four DQLMs, one for each byte (32-bit interface). Each DQLM is the longest Manhattan distance of the byte; therefore: DQLM0 = DQLMX0 + DQLMY0 DQLM1 = DQLMX1 + DQLMY1 DQLM2 = DQLMX2 + DQLMY2 DQLM3 = DQLMX3 + DQLMY3 Figure 8-80.

Data termination should use built-in ODT functionality. DQLMn is the longest Manhattan distance of a byte. For definition, see Section 8.13.4.2.4.13.2 and Figure 8-80. 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 classes 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 (w) 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. The most important thing to do is control the impedance so inadvertent impedance mismatches are not created. Generally speaking, center-to-center spacing should be either 2w or slightly larger than 2w to achieve a differential impedance equal to twice the singleended impedance, Zo.

The McASP is useful for time-division multiplexed (TDM) stream, Inter-Integrated Sound (I2S) protocols, and inter-component digital audio interface transmission (DIT). 8.14.1 McASP Device-Specific Information The device includes six multichannel audio serial port (McASP) interface peripherals (McASP0, McASP1, McASP2, McASP3, McASP4, and McASP5). The McASP module consists of a transmit and receive section. On McASP0/1, 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. On McASP2, McASP3, McASP4, and McASP5, the transmit and receive sections must always 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. 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 and McASP1 modules have up to 10 serial data pins, while McASP2, McASP3, McASP4, and McASP5 are limited to up to four 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 Multichannel Audio Serial Port (McASP) chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 8.14.2 McASP0, McASP1, McASP2, McASP3, McASP4, and McASP5 Peripheral Registers Descriptions Table 8-77.

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 Multichannel Buffered Serial Port (McBSP) chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 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. 8.15.1 McBSP Peripheral Register Descriptions Table 8-80.

For more information on the AC timing specifications, see Sections 4.3.3.5 and 4.3.4.4 of the PCI Express Base 2.0 Specification. 8.17.3 PCIe Design and Layout Guidelines 8.17.3.1 Clock Source A standard 100-MHz PCIe differential clock source must be used for PCIe operation (for more details, see Section 7.4.2, SERDES CLKN/P Input Clock). 8.17.3.2 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 8.17.3.2.1, Coupling Capacitors. The use of PCIe-compatible bridges and switches is allowed for interfacing with more than one other processor or PCIe device. 344 Peripheral Information and Timings Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 8.17.3.2.1 Coupling Capacitors AC coupling capacitors are required on the transmit data pair.

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. 8.17.3.3 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. 8.17.3.3.1 PCB Stackup Specifications Table 8-97 shows the stackup and feature sizes required for these types of PCIe connections.

Per IPC-7351A BGA pad size guideline. 8.17.3.3.2 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.

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 8-98 shows the routing specifications for the PCIe data signals. Table 8-98.

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 Multichannel Serial Port Interface (McSPI) chapter of the TMS320DM814x DaVinci Digital Media Processors Technical Reference Manual (Literature Number: SPRUGZ8). 8.19.1 SPI Peripheral Register Descriptions Table 8-104.

The support documentation for the tools is electronically available within the Code Composer Studio™ Integrated Development Environment (IDE). The following products support development of TMS320DM814x processor 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 DaVinci Digital Media Processor application. Hardware Development Tools: Extended Development System (XDS™) Emulator For a complete listing of development-support tools for the DM814x DaVinci™ Digital Media Processor 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 and Development-Support Tool Nomenclature To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP + ARM devices and support tools. Each DSP + ARM commercial family member has one of three prefixes: TMX, TMP, or TMS (for example, TMX320DM8148BCYE0). 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 (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS). Device development evolutionary flow: TMX Experimental device that is not necessarily representative of the final device's electrical specifications. TMP Final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification. TMS Fully-qualified production device. 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. TMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer: "Developmental product is intended for internal evaluation purposes." TMS 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 (TMX or TMP) 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. 370 Device and Documentation Support Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320DM8148 TMS320DM8147 TMS320DM8148, TMS320DM8147 www.ti.com SPRS647E – MARCH 2011 – REVISED DECEMBER 2013 TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, CYE), the temperature range (for example, "Blank" is the commercial temperature range), and the device speed range in megahertz (for example, "Blank" is the default [600MHz ARM, 500-MHz DSP]). Figure 9-1 provides a legend for reading the complete device name for any TMS320DM814x platform member. For device part numbers and further ordering information of TMS320DM814x devices in the CYE package type, see the TI website (www.ti.com) or contact your TI sales representative.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection. Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s noncompliance with the terms and provisions of this Notice.
