The C62x DSP devices are based on the high-performance, advanced VelociTI very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these DSPs an excellent choice for multichannel and multifunction applications. The TMS320C62x DSP offers cost-effective solutions to high-performance DSP-programming challenges. The TMS320C6203B has a performance capability of up to 2400 MIPS at a clock rate of 300 MHz. The C6203B DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors. This processor has 32 general-purpose registers of 32-bit word length and eight highly independent functional units. The eight functional units provide six arithmetic logic units (ALUs) for a high degree of parallelism and two 16-bit multipliers for a 32-bit result. The C6203B can produce two multiply-accumulates (MACs) per cycle for a total of 600 million MACs per second (MMACS). The C6203B DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals. The C6203B device program memory consists of two blocks, with a 256K-byte block configured as memory-mapped program space, and the other 128K-byte block user-configurable as cache or memory-mapped program space. Data memory for the C6203B consists of two 256K-byte blocks of RAM. The C6203B device has a powerful and diverse set of peripherals. The peripheral set includes three multichannel buffered serial ports (McBSPs), two general-purpose timers, a 32-bit expansion bus (XBus) that offers ease of interface to synchronous or asynchronous industry-standard host bus protocols, and a glueless 32-bit external memory interface (EMIF) capable of interfacing to SDRAM or SBSRAM and asynchronous peripherals. The C62x devices have 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. device characteristics Table 1 provides an overview of the TMS320C6203B, TMS320C6202, TMS320C6202B, and TMS320C6204 DSPs. The table shows significant features of each device, including the capacity of on-chip RAM, the peripherals, the execution time, and the package type with pin count, etc. This data sheet primarily focuses on the functionality of the TMS320C6203B device although it also identifies to the user the pin-compatibility of the C6203B and C6202 GLS, and the C6204 GLW BGA packages.

POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 7 TMS320C6203B FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS086M − JANUARY 1999 − REVISED MARCH 2004 CPU (DSP core) description The CPU fetches VelociTI advanced very-long instruction words (VLIW) (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 C62x CPU from other VLIW architectures. 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 16 32-bit registers for a total of 32 general-purpose registers. The two sets of functional units, along with two register files, compose sides A and B of the CPU [see the functional and CPU (DSP core) block diagram and Figure 1]. The four functional units on each side of the CPU can freely share the 16 registers belonging to that side. Additionally, each side features 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. While 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, register access using the register file across the CPU supports one read and one write per cycle. Another key feature of the C62x 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 C62x CPU supports a variety of indirect addressing modes using either linear- or circular-addressing modes with 5- or 15-bit offsets. All instructions are conditional, and most can access any one of the 32 registers. Some registers, however, are singled out to support specific addressing or to hold the condition for conditional instructions (if the condition is not automatically “true”). The two .M functional units are dedicated for multiplies. The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results available every clock cycle. 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. If an execute packet crosses the 256-bit-wide fetch-packet boundary, the assembler places it in the next fetch packet, while the remainder of the current fetch packet is padded with NOP instructions. 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 or half-words as well. All load and store instructions are byte-, half-word, or word-addressable. 8 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 TMS320C6203B FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS086M − JANUARY 1999 − REVISED MARCH 2004 CPU (DSP core) description (continued) ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ Á ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ Á Á ÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ Á Á ÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁ Á ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ Á Á src1 .L1 src2 dst long dst long src ST1 Data Path A long src long dst dst .S1 src1 8 .M1 dst src1 LD1 DA1 DA2 .D2 dst src1 src2 1X src2 src1 dst Á Á Á Á src2 src1 dst src2 Data Path B src1 dst long dst long src .S2 ST2 long src long dst dst .L2 src2 src1 Register File A (A0−A15) 2X LD2 .M2 32 Á Á Á Á src2 .D1 8 8 src2 ÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁ ÁÁ Register File B (B0−B15) 8 32 8 Á Á Á Á 8 Control Register File Figure 1.

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 14. 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).

POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 31 TMS320C6203B FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS086M − JANUARY 1999 − REVISED MARCH 2004 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 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. TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, GLS), the temperature range (for example, blank is the default commercial temperature range), and the device speed range in megahertz (for example, -300 is 300 MHz). Table 15 lists the device orderable part numbers (P/Ns) and Figure 4 provides a legend for reading the complete device name for any member of the TMS320C6000 DSP platform. For more information on the C6203B device orderable P/Ns, visit the Texas Instruments web site on the Worldwide web at http://www.ti.com URL, or contact the nearest TI field sales office or authorized distributor. 32 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 TMS320C6203B FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS086M − JANUARY 1999 − REVISED MARCH 2004 device and development-support tool nomenclature (continued) Table 15.

This source clock either drives the PLL, which multiplies the source clock in 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 5, and Table 16 through Table 18 show the external PLL circuitry for either x1 (PLL bypass) or x4 PLL multiply modes. Figure 6 shows the external PLL circuitry for a system with ONLY x1 (PLL bypass) mode. To minimize the clock jitter, a single clean power supply should power both the C6203B device and the external clock oscillator circuit. Noise coupling into PLLF directly impacts PLL clock jitter. The minimum CLKIN rise and fall times should also be observed.

NOTES: A. Keep the lead length and the number of vias between pin PLLF, pin PLLG, R1, C1, and C2 to a minimum. In addition, place all PLL components (R1, C1, C2, C3, C4, and EMI Filter) as close to the C6000 DSP device as possible. Best performance is achieved with the PLL components on a single side of the board without jumpers, switches, or components other than the ones shown. B. For reduced PLL jitter, maximize the spacing between switching signals and the PLL external components (R1, C1, C2, C3, C4, and the EMI Filter). C. The 3.3-V supply for the EMI filter must be from the same 3.3-V power plane supplying the I/O voltage, DVDD. D. EMI filter manufacturer: TDK part number ACF451832-333, 223, 153, 103.

Logic 0 should be used when writing to the reserved bit (bit 15) of the PWRD field. The CSR is discussed in detail in the TMS320C6000 CPU and Instruction Set Reference Guide (literature number SPRU189). 31 16 15 14 13 12 11 10 Reserved Enable or non-enabled interrupt wake Enabled interrupt wake PD3 PD2 PD1 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 7 9 8 0 Legend: R/W−x = Read/write reset value NOTE: The shadowed bits are not part of the power-down logic discussion and therefore are not covered here. For information on these other bit fields in the CSR register, see the TMS320C6000 CPU and Instruction Set Reference Guide (literature number SPRU189). Figure 8. PWRD Field of the CSR Register Power-down mode PD1 takes effect eight to nine clock cycles after the instruction that sets the PWRD bits in the CSR. If PD1 mode is terminated by a non-enabled interrupt, the program execution returns to the instruction where PD1 took effect . If PD1 mode is terminated by an enabled interrupt, the interrupt service routine will be executed first, then the program execution returns to the instruction where PD1 took effect. The GIE bit in CSR and the NMIE bit in the interrupt enable register (IER) must also be set in order for the interrupt service routine to execute; otherwise, execution returns to the instruction where PD1 took effect upon PD1 mode termination by an enabled interrupt. PD2 and PD3 modes can only be aborted by device reset. Table 19 summarizes all the power-down modes. 38 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 TMS320C6203B FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS086M − JANUARY 1999 − REVISED MARCH 2004 triggering, wake-up, and effects (continued) Table 19.

All functional I/O “freeze” in the last state when the PLL clock is turned off.† Following reset, the PLL needs time to re-lock, just as it does following power-up. Wake-up from PD3 takes longer than wake-up from PD2 because the PLL needs to be re-locked. Reserved — other CPU halted (except for the interrupt logic) Power down mode blocks the internal clock inputs at the Power-down boundary of the CPU, preventing most of its logic from switching. During PD1, DMA transactions can proceed between peripherals and internal memory. † On the C6203B, both the PD2 and PD3 signals assert the PD pin for external recognition of these two power-down modes. ‡ When entering PD2 and PD3, all functional I/O will remain in the previous state. However, for peripherals which are asynchronous in nature (HPI) or peripherals with an external clock source (McBSP, XBUS, timers), output signals may transition in response to stimulus on the inputs. Peripheral operation may not perform as intended under these conditions. peripheral power-down mode for TMS320C6203B The C6203B has the ability to turn off clocks to individual peripherals on the device. This feature allows the user to selectively turn off peripherals which are not being used for a specific application and not pay the extra price in power consumption for unused peripherals.

The user must be careful to not disable a portion of the device which is being used, since the peripheral becomes non-operational once disabled. A clock-off mode can be entered and exited depending on the needs of the application. For example, if an application does not need the serial ports, the ports can be disabled and then re-enabled when needed. While a peripheral is in power-down mode, no writes to the peripheral’s registers will occur; and reads from the peripheral will produce invalid data. When re-enabling any of the peripheral power-down bits, the CPU should wait at least 5 additional clock cycles before attempting to access that peripheral. 40 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 TMS320C6203B FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS086M − JANUARY 1999 − REVISED MARCH 2004 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. system-level design considerations System-level design considerations, such as bus contention, may require supply sequencing to be implemented. In this case, the core supply should be powered up at the same time as, or prior to (and powered down after), the I/O buffers. This is to ensure that the I/O buffers receive valid inputs from the core before the output buffers are powered up, therefore, preventing bus contention with other chips on the board. 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 10). I/O Supply DVDD Schottky Diode C6000 DSP Core Supply CVDD VSS GND Figure 10. 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. On systems using C62x and C67x DSPs, the core may consume in excess of 2 A per DSP until the I/O supply powers on. This extra current results from uninitialized logic within the DSP(s). A normal current state returns once the I/O power supply turns on and the CPU sees a clock pulse. Decreasing the amount of time between the core supply power-up and the I/O supply power-up reduces the effects of the current draw. If the external supply to the DSP core cannot supply the excess current, the minimum core voltage may not be achieved until after normal current returns. This voltage starvation of the core supply during power up does not affect run-time operation. Voltage starvation can affect power supply systems that gate the I/O supply via the core supply, causing the I/O supply to never turn on. During the transition from excess to normal current, a voltage spike may be seen on the core supply. Care must be taken when designing overvoltage protection circuitry on the core supply to not restart the power sequence due to this spike. Otherwise, the supply may cycle indefinitely.

For these C62x devices, this pin is internally pulled down, holding the JTAG port in reset by default. This is typically only a problem in systems where the DSP shares a scan chain with some other device. Some JTAG programmers for these other devices do not actively drive TRST high, leaving the scan chain inoperable while the C62x JTAG port is held in reset. TI emulators do drive TRST high, so the external pullup resistor is not needed in systems where TI emulators are the only devices that control JTAG scan chains on which the DSP(s) reside. If the system has other devices in the same scan chain as the DSP, and the programmer for these devices does not drive TRST high, then an external 1-kΩ pullup resistor is required. With this external 1-kΩ pullup resistor installed, care must be taken to keep the DSP in a usable state under all circumstances. When TRST is pulled up, the JTAG driver must maintain the TMS signal high for 5 TCLK cycles, forcing the DSP(s) into the test logic reset (TLR) state. From the TLR state, the DSP’s data scan path can be put in bypass (scan all 1s into the IR) to scan the other devices. The TLR state also allows normal operation of the DSP. If operation without anything driving the JTAG port is desired, the pullup resistor should be jumpered so that it may be engaged for programming the other devices and disconneted for running without a JTAG programmer or emulator. 42 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 TMS320C6203B FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS086M − JANUARY 1999 − REVISED MARCH 2004 absolute maximum ratings over operating case temperature ranges (unless otherwise noted)† Supply voltage range, CVDD (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . − 0.3 V to 1.8 V Supply voltage range, DVDD (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.3 V to 4 V Input voltage range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.3 V to 4 V Output voltage range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.3 V to 4 V Operating case temperature ranges, TC: (default) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0_C to 90_C (A version): C6203BGNZA-250 . . . . . . . . . . . . . . . . . −40_C to105_C Storage temperature range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −65_C to 150_C Temperature cycle range, (1000-cycle performance) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −40_C to 125_C † Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

As a good board design practice, such delays must always be taken into account. Timing values may be adjusted by increasing/decreasing such delays. TI recommends utilizing the available I/O buffer information specification (IBIS) models to analyze the timing characteristics correctly. To properly use IBIS models to attain accurate timing analysis for a given system, see the Using IBIS Models for Timing Analysis application report (literature number SPRA839). If needed, external logic hardware such as buffers may be used to compensate any timing differences. For 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 21 and Figure 14). Figure 14 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. Table 21.
