TMS320C6202GJL250

Digital Signal Processor Dsp Overview

The TMS320C6202GJL-250 is a fixed-point digital signal processor from the TMS320C62x generation, operating at a 250 MHz clock rate with a 4 ns instruction cycle time. It delivers up to 1600 MIPS using the VelociTI VLIW architecture, featuring eight independent functional units: six 32/40-bit ALUs and two 16-bit multipliers capable of producing 32-bit results. The device includes 3 M-bit on-chip SRAM (2 M-bit program/cache and 1 M-bit dual-access data) and a 32-bit external memory interface supporting SDRAM, SBSRAM, SRAM, and EPROM. It is housed in a 352-pin GJL BGA package.

Digital Signal Processor Dsp Feature Summary

• VelociTI VLIW C62x DSP core with eight highly independent functional units (six ALUs, two multipliers)
• 3 M-bit internal SRAM organized as 2 M-bit program/cache and 1 M-bit dual-access data
• Glueless 32-bit EMIF for synchronous (SDRAM/SBSRAM) and asynchronous (SRAM/EPROM) memories
• Four-channel bootloading DMA controller with auxiliary channel

Digital Signal Processor Dsp Applications

• Multichannel audio and video processing
• T1/E1, MVIP, and SCSA framing applications
• AC97-compatible audio systems
• SPI-compatible peripheral interfaces

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'GJL' corresponds to the 352-pin BGA package and '-250' indicates the 250 MHz speed grade. Confirm that the component is the standard TMS320C6202 variant requiring 1.8-V core voltage, distinct from the C6202B which uses 1.5-V core voltage. Ensure compatibility with existing board designs regarding pin-out and power sequencing requirements.

Digital Signal Processor Dsp Selection Notes

Select this model when a 250 MHz performance level is required with the specific 352-pin GJL package footprint. Note that the C6202 operates at 1.8 V core voltage, whereas the pin-compatible C6202B/C6203B/C6204 devices operate at 1.5 V or 1.7 V. Verify PLL multiplier options (x1, x4) are sufficient for the target system clock configuration.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320C6000 DSP platform's C62x fixed-point generation. It is pin-compatible with the TMS320C6203B GLS package and the TMS320C6204 GLW package, facilitating design migration within the family. The GJL package is specific to the C6202/C6202B devices and differs from the 384-pin GLS/GNY packages used by other variants.

Digital Signal Processor Dsp Replacement Considerations

Pin-compatible replacements include the TMS320C6203B (GLS package) and TMS320C6204 (GLW package). However, these alternatives differ in core supply voltage (1.5 V or 1.7 V vs. 1.8 V for C6202) and on-chip memory sizes. Direct substitution requires verification of power supply rails and memory mapping configurations.
