description
The TMS320C6202 and TMS320C6202B devices are part of the TMS320C62x fixed-point DSP generation
in the TMS320C6000 DSP platform. 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 TMS320C6202/02B has a performance capability of up to 2400 million instructions per second (MIPS) at
300 MHz. The C6202/02B DSP possesses the operational flexibility of high-speed controllers and the numerical
capability of array processors. These processors have 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 C6202/02B can produce two
multiply-accumulates (MACs) per cycle. This gives a total of 600 million MACs per second (MMACS) for the
C6202/02B device. The C6202/02B DSP also has application-specific hardware logic, on-chip memory, and
additional on-chip peripherals.
The C6202/02B devices program memory consists of two blocks, with a 128K-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 C6202/02B consists of two 64K-byte blocks of RAM.

SPRS104I − OCTOBER 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.

memory map summary
Table 2 shows the memory map address ranges of the C6202/02B device. The C6202/02B device has the
capability of a MAP 0 or MAP 1 memory block configuration. These memory block configurations are set up at
reset by the boot configuration pins (generically called BOOTMODE[4:0]). For the C6202/02B device, the
BOOTMODE configuration is handled, at reset, by the expansion bus module (specifically XD[4:0] pins). For
more detailed information on the C6202/02B device settings, which include the device boot mode configuration
at reset and other device-specific configurations, see TMS320C620x/C670x DSP Boot Modes and
Configuration (literature number SPRU642).

interrupt sources and interrupt selector
The C62x DSP core supports 16 prioritized interrupts, which are listed in Table 15. 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 15. 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).

Interrupts INT_00 through INT_03 are non-maskable and fixed.
Interrupts INT_04 through INT_15 are programmable by modifying the binary selector values in the Interrupt Selector Control
registers fields. Table 15 shows the default interrupt sources for Interrupts INT_04 through INT_15. For more detailed information
on interrupt sources and selection, see TMS320C6000 DSP Interrupt Selector Reference Guide (literature number SPRU646).

For the C6202 GJL package only, the C11 pin is ground (V ). For all C62x GNZ packages, the C11 pin is CLKMODE1.
SS
For the C6202 GLS package, the CLKMODE2 (A14) and CLKMODE1 (A9) pins are internally unconnected.
PLLV, PLLG, and PLLF are not part of external voltage supply or ground. See the Clock PLL section for information on how to connect these
pins.

For emulation and normal operation, pull up EMU1 and EMU0 with a dedicated 20-kΩ resistor. For boundary scan, pull down EMU1 and EMU0
with a dedicated 20-kΩ resistor.

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:
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, -250 is 250 MHz).
Table 16 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 C6202/02B
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.

applications development. The types of documentation available include: data sheets, such as this document,
with design specifications; complete user’s reference guides for all devices and tools; technical briefs;
development-support tools; on-line help; and hardware and software applications. The following is a brief,
descriptive list of support documentation specific to the C6000 DSP devices:
The TMS320C6000 CPU and Instruction Set Reference Guide (literature number SPRU189) describes the
C6000 CPU (DSP core) architecture, instruction set, pipeline, and associated interrupts.
The TMS320C6000 DSP Peripherals Overview Reference Guide (literature number SPRU190) briefly
describes the functionality of the peripherals available on the C6000 DSP platform of devices, such as the
64-/32-/16-bit external memory interfaces (EMIFs), 32-/16-bit host-port interfaces (HPIs), multichannel buffered
serial ports (McBSPs), direct memory access (DMA), enhanced direct-memory-access (EDMA) controller,
expansion bus (XBus), peripheral component interconnect (PCI), clocking and phase-locked loop (PLL); and
power-down modes.
The How to Begin Development Today and Migrate Across the TMS320C6202/02B/03B/04 DSPs Application
Report (literature number SPRA603) describes the migration concerns and identifies the similarities and
differences between the C6202, C6202B, C6203B, and C6204 C6000 DSP devices.
The TMS320C6202, TMS320C6202B Digital Signal Processors Silicon Errata (literature number SPRZ152)
describes the known exceptions to the functional specifications for particular silicon revisions of the
TMS320C6202 device . There are currently no known silicon advisories on the TMS320C6202B device.
The Using IBIS Models for Timing Analysis Application Report (literature number SPRA839) describes how to
properly use IBIS models to attain accurate timing analysis for a given system.
The tools support documentation is electronically available within the Code Composer Studio IDE. For a
complete listing of the latest C6000 DSP documentation, visit the Texas Instruments web site on the Worldwide
Web at http://www.ti.com uniform resource locator (URL).
clock PLL
All of the internal C6202/02B clocks are generated from a single source through the CLKIN pin. 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 17 through Table 20 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 C6202/02B 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. For the input clock timing requirements, see the Input and Output
Clocks electricals section.

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, DV

triggering, wake-up, and effects
The power-down modes and their wake-up methods are programmed by setting the PWRD field (bits 10−15)
of the control status register (CSR). The PWRD field of the CSR is shown in Figure 8 and described in Table 21.
When writing to the CSR, all bits of the PWRD field should be set at the same time. 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).

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.

On the C6202/C6202B, 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 TMS320C6202/6202B
The C6202/C6202B 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 Figure 9 title displays the peripheral power down register address location and Figure 9 itself shows the
register fields.

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.
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, thus, 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).

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.

IEEE 1149.1 JTAG compatibility statement
For compatibility with IEEE 1149.1 JTAG programmers, the TRST pin may need to be externally pulled up via
a 1-kΩ resistor. 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 can be engaged for programming the other devices and disconneted for running without
a JTAG programmer or emulator.

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. 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 23 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.

To ensure data setup time, simply program the strobe width wide enough. ARDY is internally synchronized. If ARDY does meet setup or hold
time, it may be recognized in the current cycle or the next cycle. Thus, ARDY can be an asynchronous input.
RS = Read Setup, RST = Read Strobe, RH = Read Hold, WS = Write Setup, WST = Write Strobe, WH = Write Hold. These parameters are
programmed via the EMIF CE space control registers.
P = 1/CPU clock frequency in ns. For example, when running parts at 250 MHz, use P = 4 ns.
The sum of RS and RST (or WS and WST) must be a minimum of 4 in order to use ARDY input to extend strobe width.

EMIF Bus consists of CE[3:0], BE[3:0], ED[31:0], EA[21:2], ARE, AOE, AWE, SDCAS/SSADS, SDRAS/SSOE, SDWE/SSWE, and SDA10.
All pending EMIF transactions are allowed to complete before HOLDA is asserted. The worst case for this is an asynchronous read or write with
external ARDY used or a minimum of eight consecutive SDRAM reads or writes when RBTR8 = 1. If no bus transactions are occurring, then the
minimum delay time can be achieved. Also, bus hold can be indefinitely delayed by setting NOHOLD = 1.

To ensure data setup time, simply program the strobe width wide enough. XRDY is internally synchronized. If XRDY does meet setup or hold
time, it may be recognized in the current cycle or the next cycle. Therefore, XRDY can be an asynchronous input.
RS = Read Setup, RST = Read Strobe, RH = Read Hold, WS = Write Setup, WST = Write Strobe, WH = Write Hold. These parameters are
programmed via the XBUS XCE space control registers.
P = 1/CPU clock frequency in ns. For example, when running parts at 250 MHz, use P = 4 ns.
The sum of RS and RST (or WS and WST) must be a minimum of 4 in order to use XRDY input to extend strobe width.

CLKRP = CLKXP = FSRP = FSXP = 0. If the polarity of any of the signals is inverted, then the timing references of that signal are also inverted.
P = 1/CPU clock frequency in ns. For example, when running parts at 250 MHz, use P = 4 ns.
The maximum bit rate for the C6202/02B device is 100 Mbps or CPU/2 (the slower of the two). Care must be taken to ensure that the AC timings
specified in this data sheet are met. The maximum bit rate for McBSP-to-McBSP communications is 100 MHz; therefore, the minimum CLKR/X
clock cycle is either twice the CPU cycle time (2P), or 10 ns (100 MHz), whichever value is larger. For example, when running parts at 250 MHz
(P = 4 ns), use 10 ns as the minimum CLKR/X clock cycle (by setting the appropriate CLKGDV ratio or external clock source). When running
parts at 100 MHz (P = 10 ns), use 2P = 20 ns (50 MHz) as the minimum CLKR/X clock cycle. The maximum bit rate for McBSP-to-McBSP
communications applies when 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.
¶
The minimum CLKR/X pulse duration is either (P−1) or 4 ns, whichever is larger. For example, when running parts at 250 MHz (P = 4 ns), use
4 ns as the minimum CLKR/X pulse duration. When running parts at 100 MHz (P = 10 ns), use (P−1) = 9 ns as the minimum CLKR/X pulse
duration.
