GNZ BGA Package (Bottom View) Bottom View 14 SPRS222 June 2003 Description 1.3 Description The TMS320C64x DSPs (including the TMS320DM641 and TMS320DM640 devices) are the highest-performance fixed-point DSP generation in the TMS320C6000 DSP platform. The TMS320DM641 and TMS320DM640 (DM641 and DM640) devices are based on the second-generation high-performance, advanced VelociTI very-long-instruction-word (VLIW) architecture (VelociTI.2) developed by Texas Instruments (TI), making these DSPs an excellent choice for digital media applications. The C64x is a code-compatible member of the C6000 DSP platform. With performance of up to 4800 million instructions per second (MIPS) at a clock rate of 600 MHz, the DM641 device offers cost-effective solutions to high-performance DSP programming challenges. With performance of up to 3200 million instructions per second (MIPS) at a clock rate of 400 MHz, the DM640 device offers cost-effective solutions to high-performance DSP programming challenges. The DM641/DM640 uses a two-level cache-based architecture and has a powerful and diverse set of peripherals. The Level 1 program cache (L1P) is a 128-Kbit direct mapped cache and the Level 1 data cache (L1D) is a 128-Kbit 2-way set-associative cache. The Level 2 memory/cache (L2) consists of an 1-Mbit memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or combinations of the two. The peripheral set includes: two configurable video ports (DM641); one configurable video port (DM640); a 10/100 Mb/s Ethernet MAC (EMAC); a management data input/output (MDIO) module; a VCXO interpolated control port (VIC); one 4-bit multichannel buffered audio serial port (McASP0); an inter-integrated circuit (I2C) Bus module; two multichannel buffered serial ports (McBSPs); three 32-bit general-purpose timers; a 16-bit host-port interface (HPI16); a 16-pin general-purpose input/output port (GP0) with programmable interrupt/event generation modes; and a 32-bit glueless external memory interface (EMIFA), which is capable of interfacing to synchronous and asynchronous memories and peripherals. The DM641 device has two configurable video port peripherals (VP0 and VP1). The DM640 device has one configurable video port peripheral (VP0). These video port peripherals provide a glueless interface to common video decoder and encoder devices. All Video Port peripherals have the capability to operate as a video-capture port, a video-display port, or a transport stream interface (TSI) capture port. The DM641/DM640 video port peripherals support multiple resolutions and video standards (e. g., CCIR601, ITU-BT.656, BT.1120, SMPTE 125M, 260M, 274M, and 296M). TMS320C6000 and C6000 are trademarks of Texas Instruments. June 2003 SPRS222 15 PRODUCT PREVIEW The DM641/DM640 DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors. The C64x DSP core processor has 64 general-purpose registers of 32-bit word length and eight highly independent functional units--two multipliers for a 32-bit result and six arithmetic logic units (ALUs)-- with VelociTI.2 extensions. The VelociTI.2 extensions in the eight functional units include new instructions to accelerate the performance in video and imaging applications and extend the parallelism of the VelociTI architecture. The DM641 can produce four 32-bit multiply-accumulates (MACs) per cycle for a total of 2400 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 4800 MMACS. The DM641/DM640 DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other C6000 DSP platform devices. Description These video port peripherals are configurable and can support either video capture and/or video display modes. For capture operation, the video port can operate as a single channel of 8-bit BT.656, 8-bit raw video, or 8-bit TSI. For display operation, the video port can operate as a single channel of 8-bit BT.656 display, 8-bit raw video display. For more details on the Video Port peripherals, see the TMS320DM642 Technical Overview (literature number SPRU615) or the TMS320C64x DSP Video Port/VCXO Interpolated Control (VIC) Port Reference Guide (literature number SPRU629). The McASP0 port supports one transmit and one receive clock zone, with four serial data pins which can be individually allocated to any of the two zones. The serial port supports time-division multiplexing on each pin from 2 to 32 time slots. The DM641/DM640 has sufficient bandwidth to support all 4 serial data pins transmitting a 192-kHz stereo signal. Serial data in each zone may be transmitted and received on multiple serial data pins simultaneously and formatted in a multitude of variations on the Philips Inter-IC Sound (I2S) format. In addition, the McASP0 transmitter may be programmed to output multiple S/PDIF, IEC60958, AES-3, CP-430 encoded data channels simultaneously, with a single RAM containing the full implementation of user data and channel status fields. McASP0 also provides extensive error-checking and recovery features, such as the bad clock detection circuit for each high-frequency master clock which verifies that the master clock is within a programmed frequency range. The VCXO interpolated control (VIC) port provides digital-to-analog conversion with resolution from 9-bits to up to 16-bits. The output of the VIC is a single bit interpolated D/A output. For more details on the VIC port, see the TMS320C64x DSP Video Port/VCXO Interpolated Control (VIC) Port Reference Guide (literature number SPRU629). The ethernet media access controller (EMAC) provides an efficient interface between the DM641/DM640 DSP core processor and the network. The DM641/DM640 EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex, with hardware flow control and quality of service (QOS) support. The DM641/DM640 EMAC makes use of a custom interface to the DSP core that allows efficient data transmission and reception. For more details on the EMAC, see the TMS320C6000 DSP Ethernet Media Access Controller (EMAC) / Management Data Input/Output (MDIO) Module Reference Guide (literature number SPRU628). The management data input/output (MDIO) module continuously polls all 32 MDIO addresses in order to enumerate all PHY devices in the system. Once a PHY candidate has been selected by the DSP, the MDIO module transparently monitors its link state by reading the PHY status register. Link change events are stored in the MDIO module and can optionally interrupt the DSP, allowing the DSP to poll the link status of the device without continuously performing costly MDIO accesses. For more details on the MDIO, see the TMS320C6000 DSP Ethernet Media Access Controller (EMAC) / Management Data Input/Output (MDIO) Module Reference Guide (literature number SPRU628). PRODUCT PREVIEW 16 SPRS222 June 2003 Description The I2C0 port on the TMS320DM641/DM640 allows the DSP to easily control peripheral devices and communicate with a host processor. In addition, the standard multichannel buffered serial port (McBSP) may be used to communicate with serial peripheral interface (SPI) mode peripheral devices. The DM641/DM640 has a complete set of development tools which includes: a new C compiler, an assembly optimizer to simplify programming and scheduling, and a Windows debugger interface for visibility into source code execution.

The common peripheral set and pin-compatibility that the DM641 and DM640 devices offer lead to easier system designs and faster time to market. The DM640 device is a sub-set of the DM641 device and does not support an HPI peripheral or a second Video Port (VP1) peripheral. Table 1-3 identifies the peripherals that are available on the DM641 and DM640 devices. Table 1-3.

Functional Block Diagram June 2003 SPRS222 21 PRODUCT PREVIEW CPU (DSP Core) Description 1.7 CPU (DSP Core) Description The CPU fetches VelociTI advanced very-long instruction words (VLIWs) (256 bits wide) to supply up to eight 32-bit instructions to the eight functional units during every clock cycle. The VelociTI VLIW architecture features controls by which all eight units do not have to be supplied with instructions if they are not ready to execute. The first bit of every 32-bit instruction determines if the next instruction belongs to the same execute packet as the previous instruction, or whether it should be executed in the following clock as a part of the next execute packet. Fetch packets are always 256 bits wide; however, the execute packets can vary in size. The variable-length execute packets are a key memory-saving feature, distinguishing the C64x CPUs from other VLIW architectures. The C64x VelociTI.2 extensions add enhancements to the TMS320C62x DSP VelociTI architecture. These enhancements include: * * Register file enhancements Data path extensions Quad 8-bit and dual 16-bit extensions with data flow enhancements Additional functional unit hardware Increased orthogonality of the instruction set Additional instructions that reduce code size and increase register flexibility PRODUCT PREVIEW * * * * The CPU features two sets of functional units. Each set contains four units and a register file. One set contains functional units .L1, .S1, .M1, and .D1; the other set contains units .D2, .M2, .S2, and .L2. The two register files each contain 32 32-bit registers for a total of 64 general-purpose registers. In addition to supporting the packed 16-bit and 32-/40-bit fixed-point data types found in the C62x VelociTI VLIW architecture, the C64x register files also support packed 8-bit data and 64-bit fixed-point data types. The two sets of functional units, along with two register files, compose sides A and B of the CPU [see the functional block and CPU (DSP core) diagram, and Figure 1-4]. The four functional units on each side of the CPU can freely share the 32 registers belonging to that side. Additionally, each side features a "data cross path"--a single data bus connected to all the registers on the other side, by which the two sets of functional units can access data from the register files on the opposite side. The C64x CPU pipelines data-cross-path accesses over multiple clock cycles. This allows the same register to be used as a data-cross-path operand by multiple functional units in the same execute packet. All functional units in the C64x CPU can access operands via the data cross path. Register access by functional units on the same side of the CPU as the register file can service all the units in a single clock cycle. On the C64x CPU, a delay clock is introduced whenever an instruction attempts to read a register via a data cross path if that register was updated in the previous clock cycle. In addition to the C62x DSP fixed-point instructions, the C64x DSP includes a comprehensive collection of quad 8-bit and dual 16-bit instruction set extensions. These VelociTI.2 extensions allow the C64x CPU to operate directly on packed data to streamline data flow and increase instruction set efficiency. This is a key factor for video and imaging applications. TMS320C62x is a trademark of Texas Instruments. 22 SPRS222 June 2003 CPU (DSP Core) Description Another key feature of the C64x CPU is the load/store architecture, where all instructions operate on registers (as opposed to data in memory). Two sets of data-addressing units (.D1 and .D2) are responsible for all data transfers between the register files and the memory. The data address driven by the .D units allows data addresses generated from one register file to be used to load or store data to or from the other register file. The C64x .D units can load and store bytes (8 bits), half-words (16 bits), and words (32 bits) with a single instruction. And with the new data path extensions, the C64x .D unit can load and store doublewords (64 bits) with a single instruction. Furthermore, the non-aligned load and store instructions allow the .D units to access words and doublewords on any byte boundary. The C64x CPU supports a variety of indirect addressing modes using either linear- or circular-addressing with 5- or 15-bit offsets. All instructions are conditional, and most can access any one of the 64 registers. Some registers, however, are singled out to support specific addressing modes or to hold the condition for conditional instructions (if the condition is not automatically "true"). The two .M functional units perform all multiplication operations. Each of the C64x .M units can perform two 16 x 16-bit multiplies or four 8 x 8-bit multiplies per clock cycle. The .M unit can also perform 16 x 32-bit multiply operations, dual 16 x 16-bit multiplies with add/subtract operations, and quad 8 x 8-bit multiplies with add operations. In addition to standard multiplies, the C64x .M units include bit-count, rotate, Galois field multiplies, and bidirectional variable shift hardware. The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results available every clock cycle. The arithmetic and logical functions on the C64x CPU include single 32-bit, dual 16-bit, and quad 8-bit operations. The processing flow begins when a 256-bit-wide instruction fetch packet is fetched from a program memory. The 32-bit instructions destined for the individual functional units are "linked" together by "1" bits in the least significant bit (LSB) position of the instructions. The instructions that are "chained" together for simultaneous execution (up to eight in total) compose an execute packet. A "0" in the LSB of an instruction breaks the chain, effectively placing the instructions that follow it in the next execute packet. A C64x DSP device enhancement now allows execute packets to cross fetch-packet boundaries. In the TMS320C62x/TMS320C67x DSP devices, if an execute packet crosses the fetch-packet boundary (256 bits wide), the assembler places it in the next fetch packet, while the remainder of the current fetch packet is padded with NOP instructions. In the C64x DSP device, the execute boundary restrictions have been removed, thereby, eliminating all of the NOPs added to pad the fetch packet, and thus, decreasing the overall code size. The number of execute packets within a fetch packet can vary from one to eight. Execute packets are dispatched to their respective functional units at the rate of one per clock cycle and the next 256-bit fetch packet is not fetched until all the execute packets from the current fetch packet have been dispatched. After decoding, the instructions simultaneously drive all active functional units for a maximum execution rate of eight instructions every clock cycle. While most results are stored in 32-bit registers, they can be subsequently moved to memory as bytes, half-words, or doublewords. All load and store instructions are byte-, half-word-, word-, or doubleword-addressable.

Table 1-29 lists the source of C64x EDMA synchronization events associated with each of the programmable EDMA channels. For the DM641/DM640 device, the association of an event to a channel is fixed; each of the EDMA channels has one specific event associated with it. These specific events are captured in the EDMA event registers (ERL, ERH) even if the events are disabled by the EDMA event enable registers (EERL, EERH). The priority of each event can be specified independently in the transfer parameters stored in the EDMA parameter RAM. For more detailed information on the EDMA module and how EDMA events are enabled, captured, processed, linked, chained, and cleared, etc., see the EDMA Controller chapter of the TMS320C6000 Peripherals Reference Guide (literature number SPRU190).

The highest-priority interrupt is INT_00 (dedicated to RESET) while the lowest-priority interrupt is INT_15. The first four interrupts (INT_00-INT_03) are non-maskable and fixed. The remaining interrupts (INT_04-INT_15) are maskable and default to the interrupt source specified in Table 1-30. The interrupt source for interrupts 4-15 can be programmed by modifying the selector value (binary value) in the corresponding fields of the Interrupt Selector Control registers: MUXH (address 0x019C0000) and MUXL (address 0x019C0004).

However, for proper DM641/DM640 device operation; the following external pins must be configured correctly: * * * For proper DM641 device operation, the HD5 pin [Y1] at device reset must be pulled down via a 10-k resistor. For proper DM641/DM60 device operation, the reserved (RSV) [E2] pin at device reset must be pulled down via a 10-k resistor. EMAC and MDIO peripherals The MAC_EN pin is latched at reset.

These registers are part of the Device Configuration module and are mapped to a 4K block memory starting at 0x01B3F000. The CPU accesses these registers via the CFGBUS. The peripheral configuration register (PERCFG), allows the user to control the peripheral selection of the Video Ports (VP0 and VP1 [DM641 only]) McBSP0, McBSP1, McASP0, and I2C0 peripherals.

In order to use these peripherals on the DM641/DM640 device, the peripheral must first be enabled in the Peripheral Configuration register (PERCFG). Software muxed pins should not be programmed to switch functionalities during run-time. Care should also be taken to ensure that no accesses are being performed before disabling the peripherals. To help minimize power consumption in the DM641/DM640 device, unused peripherals may be disabled. Figure 2-2 shows the flow needed to enable (or disable) a given peripheral on the DM641/DM640 devices.

Peripheral Enable/Disable Flow Diagram A 32-bit key (value = 0x10C0010C) must be written to the Peripheral Configuration Lock register (PCFGLOCK) in order to unlock access to the PERCFG register. Reading the PCFGLOCK register determines whether the PERCFG register is currently locked (LOCKSTAT bit = 1) or unlocked (LOCKSTAT bit = 0), see Figure 2-3.

PCFGLOCK Register Selection Bit Descriptions - Write Accesses BIT 31:0 NAME LOCK DESCRIPTION Lock bits. 0x10C0010C = Unlocks PERCFG register accesses. Any write to the PERCFG register will automatically relock the register. In order to avoid the unnecessary overhead of multiple unlock/enable sequences, all peripherals should be enabled with a single write to the PERCFG register with the necessary enable bits set. Prior to waiting 128 CPU cycles, the PERCFG register should be read. There is no direct correlation between the CPU issuing a write to the PERCFG register and the write actually occurring. Reading the PERCFG register after the write is issued forces the CPU to wait for the write to the PERCFG register to occur. Once a peripheral is enabled, the DSP (or other peripherals such as the McBSP) must wait a minimum of 128 CPU cycles before accessing the enabled peripheral. The user must ensure that no accesses are performed to a peripheral while it is disabled.

This bit is read as a "1" for DM641/DM640. 2.4 Multiplexed Pins Multiplexed pins are pins that are shared by more than one peripheral and are internally multiplexed. Some of these pins are configured by software, and the others are configured by external pullup/pulldown resistors only at reset. Those muxed pins that are configured by software should not be programmed to switch functionalities during run-time. Those muxed pins that are configured by external pullup/pulldown resistors are mutually exclusive; only one peripheral has primary control of the function of these pins after reset. Table 2-8 identifies the multiplexed pins on the DM641/DM640 device; shows the default (primary) function and the default settings after reset; and describes the pins, registers, etc. necessary to configure specific multiplexed functions. June 2003 SPRS222 61 PRODUCT PREVIEW Configuration Examples 2.5 Debugging Considerations It is recommended that external connections be provided to device configuration pins, including AEA[22:19] and TOUT0/MAC_EN. Although internal pullup/pulldown resistors exist on these pins, providing external connectivity adds convenience to the user in debugging and flexibility in switching operating modes. Internal pullup/pulldown resistors also exist on the non-configuration pins on the AEA bus (AEA[18:0]). Do not oppose the internal pullup/pulldown resistors on these non-configuration pins with external pullup/pulldown resistors. If an external controller provides signals to these non-configuration pins, these signals must be driven to the default state of the pins at reset, or not be driven at all. For the internal pullup/pulldown resistors for all device pins, see the terminal functions table. Table 2-8. DM641/DM640 Device Multiplexed Pins MULTIPLEXED PINS NAME NO.

June 2003 SPRS222 89 PRODUCT PREVIEW Device and Development-Support Tool Nomenclature 2.9 Device and Development-Support Tool Nomenclature To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all TMS320 DSP devices and support tools. Each TMS320 DSP commercial family member has one of three prefixes: TMX, TMP, or TMS. Texas Instruments recommends two of three possible prefix designators for 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 TMP TMS Experimental device that is not necessarily representative of the final device's electrical specifications Final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification Fully qualified production device Support tool development evolutionary flow: PRODUCT PREVIEW 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 with appropriate disclaimers describing their limitations and intended uses. Experimental devices (TMX) may not be representative of a final product and Texas Instruments reserves the right to change or discontinue these products without notice. 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. TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, GDK), the temperature range (for example, blank is the default commercial temperature range), and the device speed range in megahertz (for example, -600 is 600 MHz). Figure 2-10 provides a legend for reading the complete device name for any TMS320C6000 DSP platform member.

PRODUCT PREVIEW 92 SPRS222 June 2003 Clock PLL 2.11 Clock PLL Most of the internal C64x DSP clocks are generated from a single source through the CLKIN pin. This source clock either drives the PLL, which multiplies the source clock frequency to generate the internal CPU clock, or bypasses the PLL to become the internal CPU clock. To use the PLL to generate the CPU clock, the external PLL filter circuit must be properly designed. Figure 2-11 shows the external PLL circuitry for either x1 (PLL bypass) or other PLL multiply modes. To minimize the clock jitter, a single clean power supply should power both the C64x DSP device and the external clock oscillator circuit. The minimum CLKIN rise and fall times should also be observed. For the input clock timing requirements, see the input and output clocks electricals section. Rise/fall times, duty cycles (high/low pulse durations), and the load capacitance of the external clock source must meet the DSP requirements in this data sheet (see the electrical characteristics over recommended ranges of supply voltage and operating case temperature table and the input and output clocks electricals section).

Use external pullup resistors on the CLKMODE pins (CLKMODE1 and CLKMODE0) to set the DM641/DM640 device to one of the valid PLL multiply clock modes (x6 or x12). With internal pulldown resistors on the CLKMODE pins (CLKMODE1, CLKMODE0), the default clock mode is x1 (bypass). Under some operating conditions, the maximum PLL lock time may vary by as much as 150% from the specified typical value. For example, if the typical lock time is specified as 100 s, the maximum value may be as long as 250 s. June 2003 SPRS222 95 PRODUCT PREVIEW Multichannel Audio Serial Port (McASP0) Peripheral 2.12 Multichannel Audio Serial Port (McASP0) Peripheral The TMS320DM641/DM640 device includes one multichannel audio serial port (McASP) interface peripheral (McASP0). The McASP is a serial port optimized for the needs of multi-channel audio applications. The McASP consists of a transmit and receive section. These sections can operate completely independently with different data formats, separate master clocks, bit clocks, and frame syncs or alternatively, the transmit and receive sections may be synchronized. The McASP module also includes a pool of 16 shift registers that may be configured to operate as either transmit data, receive data, or general-purpose I/O (GPIO). 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 supports the TDM synchronous serial format. The McASP 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 DSPs). The McASP peripheral has additional capability for flexible clock generation, and error detection/handling, as well as error management. For more detailed information on and the functionality of the McASP peripheral, see the TMS320C6000 DSP Multichannel Audio Serial Port (McASP) Reference Guide (literature number SPRU041).

The video port peripheral can operate as a video capture port, video display port, or as a transport stream interface (TSI) capture port. The port consists of a single channel A. A 2460-byte capture/display buffer is utilized on this channel. The port is always configured for either video capture or display only. Separate data pipelines control the parsing and formatting of video capture or display data for each of the BT.656, raw video, and TSI modes. For video capture operation, the video port may operate as a single channel of 8-bit BT.656, 8-bit raw video, or 8-bit TSI. For video display operation, the video port may operate as 8-bit BT.656 or 8-bit raw video. June 2003 SPRS222 99 PRODUCT PREVIEW VIC 2.15 VIC The VCXO interpolated control (VIC) port provides digital-to-analog conversation with resolution from 9-bits to up to 16-bits. The output of the VIC is a single bit interpolated D/A output (VDAC pin). Typical D/A converters provide a discrete output level for every value of the digital word that is being converted. This is a problem for digital words that are long. This is avoided in a Sigma Delta type D/A converter by choosing a few widely spaced output levels and interpolating values between them. The interpolating mechanism causes the output to oscillate rapidly between the levels in such a manner that the average output represents the value of input code. In the VIC, two output levels are chosen (0 and 1), and Sigma Delta interpolation scheme is implemented to interpolate between these levels with a rapidly changing signal. The frequency of interpolation is dependent on the resolution needed. When the video port is used in transport stream interface (TSI) mode, the VIC port is used to control the system clock, VCXO, for MPEG transport stream. PRODUCT PREVIEW The VIC supports the following features: * * * Single interpolation for D/A conversion Programmable precision from 9-to-16 bits Interface for register accesses 100 SPRS222 June 2003 EMAC 2.16 EMAC The ethernet media access controller (EMAC) provides an efficient interface between the DM641/DM640 DSP core processor and the network. The DM641/DM640 EMAC support both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex, with hardware flow control and quality of service (QOS) support. The DM641/DM640 EMAC makes use of a custom interface to the DSP core that allows efficient data transmission and reception. The EMAC controls the flow of packet data from the DSP to the PHY. The MDIO module controls PHY configuration and status monitoring. Both the EMAC and the MDIO modules interface to the DSP through a custom interface that allows efficient data transmission and reception. This custom interface is referred to as the EMAC control module, and is considered integral to the EMAC/MDIO peripheral. The control module is also used to control device reset, interrupts, and system priority. June 2003 SPRS222 101 PRODUCT PREVIEW MDIO 2.17 MDIO The management data input/output (MDIO) module continuously polls all 32 MDIO addresses in order to enumerate all PHY devices in the system. The management data input/output (MDIO) module implements the 802.3 serial management interface to interrogate and control Ethernet PHY(s) using a shared two-wire bus. Host software uses the MDIO module to configure the auto-negotiation parameters of each PHY attached to the EMAC, retrieve the negotiation results, and configure required parameters in the EMAC module for correct operation. The module is designed to allow almost transparent operation of the MDIO interface, with very little maintenance from the core processor. PRODUCT PREVIEW 102 SPRS222 June 2003 Power-Supply Sequencing 2.18 Power-Supply Sequencing TI DSPs do not require specific power sequencing between the core supply and the I/O supply. However, systems should be designed to ensure that neither supply is powered up for extended periods of time (>1 second) if the other supply is below the proper operating voltage. 2.18.1 Power-Supply Design Considerations A dual-power supply with simultaneous sequencing can be used to eliminate the delay between core and I/O power up. A Schottky diode can also be used to tie the core rail to the I/O rail (see Figure 2-14). I/O Supply DVDD Schottky Diode CVDD VSS GND Figure 2-14. Schottky Diode Diagram Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize inductance and resistance in the power delivery path. Additionally, when designing for high-performance applications utilizing the C6000 platform of DSPs, the PC board should include separate power planes for core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors. TI DSPs do not require specific power sequencing between the core supply and the I/O supply. However, systems should be designed to ensure that neither supply is powered up for extended periods of time if the other supply is below the proper operating voltage. 2.19 Power-Supply Decoupling In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as possible close to the DSP. Assuming 0603 caps, the user should be able to fit a total of 60 caps, 30 for the core supply and 30 for the I/O supply. These caps need to be close to the DSP, no more than 1.25 cm maximum distance to be effective. Physically smaller caps are better, such as 0402, but need to be evaluated from a yield/manufacturing point-of-view. Parasitic inductance limits the effectiveness of the decoupling capacitors, therefore physically smaller capacitors should be used while maintaining the largest available capacitance value. As with the selection of any component, verification of capacitor availability over the product's production lifetime should be considered. June 2003 SPRS222 103 PRODUCT PREVIEW Core Supply C6000 DSP Power-Down Operation 2.20 Power-Down Operation The DM641/DM640 device can be powered down in three ways: * * * Power-down due to pin configuration Power-down due to software configuration - relates to the default state of the peripheral configuration bits in the PERCFG register. Power-down during run-time via software configuration On the DM641/DM640 device, the EMAC and MDIO peripherals are controlled (selected) at the pin level during chip reset (e.g., using the MAC_EN pin). The McASP0, McBSP0, McBSP1, VP0, VP1 [DM641 only], and I2C0 peripheral functions are selected via the peripheral configuration (PERCFG) register bits. For more detailed information on the peripheral configuration pins and the PERCFG register bits, see the Device Configurations section of this document. 2.21 IEEE 1149.1 JTAG Compatibility Statement PRODUCT PREVIEW The TMS320DM641/DM640 DSP requires that both TRST and RESET be asserted upon power up to be properly initialized. While RESET initializes the DSP core, TRST initializes the DSP's emulation logic. Both resets are required for proper operation. While both TRST and RESET need to be asserted upon power up, only RESET needs to be released for the DSP to boot properly. TRST may be asserted indefinitely for normal operation, keeping the JTAG port interface and DSP's emulation logic in the reset state. TRST only needs to be released when it is necessary to use a JTAG controller to debug the DSP or exercise the DSP's boundary scan functionality. For maximum reliability, the TMS320DM641/DM640 DSP includes an internal pulldown (IPD) on the TRST pin to ensure that TRST will always be asserted upon power up and the DSP's internal emulation logic will always be 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 intialize the DSP after powerup and externally drive TRST high before attempting any emulation or boundary scan operations. Following the release of RESET, the low-to-high transition of TRST must be "seen" to latch the state of EMU1 and EMU0. The EMU[1:0] pins configure the device for either Boundary Scan mode or Emulation mode. For more detailed information, see the terminal functions section of this data sheet. 104 SPRS222 June 2003 EMIF Device Speed 2.22 EMIF Device Speed The rated EMIF speed of these devices only applies to the SDRAM interface when in a system that meets the following requirements: * * * * * 1 bank (maximum of 2 chips) of SDRAM connected to EMIF up to 1 bank of buffers connected to EMIF EMIF trace lengths between 1 and 3 inches 183-MHz SDRAM for 133-MHz operation 143-MHz SDRAM for 100-MHz operation Other configurations may be possible, but timing analysis must be done to verify all AC timings are met. Verification of AC timings is mandatory when using configurations other than those specified above. TI recommends utilizing I/O buffer information specification (IBIS) to analyze all AC timings. 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). June 2003 SPRS222 105 PRODUCT PREVIEW To maintain signal integrity, serial termination resistors should be inserted into all EMIF output signal lines (see the Terminal Functions table for the EMIF output signals). Bootmode 2.23 Bootmode The DM641/DM640 device resets using the active-low signal RESET. While RESET is low, the device is held in reset and is initialized to the prescribed reset state. Refer to reset timing for reset timing characteristics and states of device pins during reset. The release of RESET starts the processor running with the prescribed device configuration and boot mode. The DM641 has three types of boot modes while the DM641 has only two types of boot modes: * Host boot [DM641 only] If host boot is selected, upon release of RESET, the CPU is internally "stalled" while the remainder of the device is released. During this period, an external host can initialize the CPU's memory space as necessary through the host interface, including internal configuration registers, such as those that control the EMIF or other peripherals. For the DM641 device, the HPI peripheral is used for host boot. Once the host is finished with all necessary initialization, it must set the DSPINT bit in the HPIC register to complete the boot process. This transition causes the boot configuration logic to bring the CPU out of the "stalled" state. The CPU then begins execution from address 0. The DSPINT condition is not latched by the CPU, because it occurs while the CPU is still internally "stalled". Also, DSPINT brings the CPU out of the "stalled" state only if the host boot process is selected. All memory may be written to and read by the host. This allows for the host to verify what it sends to the DSP if required. After the CPU is out of the "stalled" state, the CPU needs to clear the DSPINT, otherwise, no more DSPINTs can be received. PRODUCT PREVIEW * EMIF boot (using default ROM timings) Upon the release of RESET, the 1K-Byte ROM code located in the beginning of CE1 is copied to address 0 by the EDMA using the default ROM timings, while the CPU is internally "stalled". The data should be stored in the endian format that the system is using. In this case, the EMIF automatically assembles consecutive 8-bit bytes to form the 32-bit instruction words to be copied. The transfer is automatically done by the EDMA as a single-frame block transfer from the ROM to address 0. After completion of the block transfer, the CPU is released from the "stalled" state and starts running from address 0. * No boot With no boot, the CPU begins direct execution from the memory located at address 0. If SDRAM is used in the system, the CPU is internally "stalled" until the SDRAM initialization is complete. Note: operation is undefined if invalid code is located at address 0. 106 SPRS222 June 2003 Electrical Specifications 3 3.1 Electrical Specifications Absolute Maximum Ratings Over Operating Case Temperature Range (Unless Otherwise Noted) CVDD (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . - 0.3 V to 1.8 V DVDD (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.3 V to 4 V Input voltage ranges: VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.3 V to 4 V Output voltage ranges: VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.3 V to 4 V Operating case temperature ranges, TC: (default) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0_C to 90_C Storage temperature range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -65_C to 150_C Supply voltage ranges: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device.

Examples of such supplies include the PT4660, PT5500, PT5520, PT6440, and PT6930 series from Power Trends, a subsidiary of Texas Instruments.

Electrical Specifications 3.5 Timing Parameters and Board Routing Analysis The timing parameter values specified in this data sheet do not include delays by board routings. As a good board design practice, such delays must always be taken into account. Timing values may be adjusted by increasing/decreasing such delays. TI recommends utilizing the available I/O buffer information specification (IBIS) models to analyze the timing characteristics correctly. If needed, external logic hardware such as buffers may be used to compensate any timing differences. For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device and from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time margin, but also tends to improve the input hold time margins (see Table 3-1 and Figure 3-4). Figure 3-4 represents a general transfer between the DSP and an external device. The figure also represents board route delays and how they are perceived by the DSP and the external device.

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.

For example, when running parts at 600 MHz, use P = 1.67 ns. The maximum bit rate for McBSP-to-McBSP communications is 75 MHz for -600 devices and 66 MHz for -500, -400 devices; therefore, the minimum CLKR/X clock cycle is either four times the CPU cycle time (4P), or 13.3 ns (75 MHz) for -600 devices [or 15 ns (66 MHz) for -500, -400 devices], whichever value is larger. For example, when running parts at 600 MHz (P = 1.67 ns), use 13.3 ns as the minimum CLKR/X clock cycle (by setting the appropriate CLKGDV ratio or external clock source). When running parts at 500 MHz (P = 2 ns), use 15 ns as the minimum CLKR/X clock cycle. The maximum bit rate for McBSP-to-McBSP communications applies to the following hardware configuration: the serial port is a Master of the clock and frame syncs (with CLKR connected to CLKX, FSR connected to FSX, CLKXM = FSXM = 1, and CLKRM = FSRM = 0) in data delay 1 or 2 mode (R/XDATDLY = 01b or 10b) and the other device the McBSP communicates to is a Slave.
