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.
TMS320C6000 is a trademark of Texas Instruments.

SPRS104G – OCTOBER 1999 – REVISED APRIL 2003
description (continued)
The C6202/02B 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 TMS320C6202, TMS320C6202B, TMS320C6203B, and the

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 the Boot Configuration section and the Boot Configuration
Summary table of the TMS320C6000 Peripherals Reference Guide (literature number SPRU190).

DMA synchronization events
The C6202/C6202B DMA supports up to four independent programmable DMA channels, plus an auxiliary
channel used for servicing the HPI module. The four main DMA channels can be read/write synchronized based
on the events shown in Table 13. Selection of these events is done via the RSYNC and WSYNC fields in the
Primary Control registers of the specific DMA channel. For more detailed information on the DMA module,
associated channels, and event-synchronization, see the Direct Memory Access (DMA) Controller chapter of
the TMS320C6000 Peripherals Reference Guide (literature number SPRU190).

interrupt sources and interrupt selector
The C62x DSP core supports 16 prioritized interrupts, which are listed in Table 14. 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).

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, -250 is 250 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 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.

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 16 through Table 19 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.

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 7).

Figure 7. 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 will 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 may be engaged for programming the other devices and disconneted for running without
a JTAG programmer or emulator.

PARAMETER MEASUREMENT INFORMATION (CONTINUED)
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 20 and Figure 11).
Figure 11 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. XRDY is internally synchronized. If XRDY does meet setup or hold
time, it may be recognized in the current cycle or the next cycle. Thus, 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.

‡ For all SPI slave modes, CLKG is programmed as 1/2 of the CPU clock by setting CLKSM = CLKGDV = 1.
§ S = sample rate generator input clock = P if CLKSM = 1 (P = 1/CPU clock frequency)
= sample rate generator input clock = P_clks if CLKSM = 0 (P_clks = CLKS period)
T = CLKX period = (1 + CLKGDV) * S
H = CLKX high pulse width = (CLKGDV/2 + 1) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
L = CLKX low pulse width = (CLKGDV/2) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
The maximum transfer rate for SPI mode is limited to the above AC timing constraints.
¶ FSRP = FSXP = 1. As a SPI master, FSX is inverted to provide active-low slave-enable output. As a slave, the active-low signal input on FSX
and FSR is inverted before being used internally.
CLKXM = FSXM = 1, CLKRM = FSRM = 0 for master McBSP
CLKXM = CLKRM = FSXM = FSRM = 0 for slave McBSP
# FSX should be low before the rising edge of clock to enable slave devices and then begin a SPI transfer at the rising edge of the master clock
(CLKX).
