TMS320C6202BGNZ250

Digital Signal Processor Dsp Overview

The TMS320C6202BGNZ250 is a fixed-point digital signal processor from the TMS320C62x family, manufactured by Texas Instruments. It operates at a maximum clock frequency of 250 MHz with a 4-ns instruction cycle time, delivering 2000 MIPS performance. The device features the VelociTI VLIW architecture with eight independent functional units: six 32/40-bit ALUs and two 16-bit multipliers capable of producing 32-bit results. It includes 3 Mbit of on-chip SRAM, comprising 2 Mbit for internal program/cache and 1 Mbit for dual-access internal data memory. The core voltage is 1.5 V, while I/Os operate at 3.3 V. It is housed in a 352-pin GNZ Ball Grid Array (BGA) package.

Digital Signal Processor Dsp Feature Summary

• VelociTI VLIW Architecture: Eight highly independent functional units (six ALUs, two multipliers) enabling up to eight instructions per cycle.
• On-Chip Memory: 3 Mbit total SRAM organized as 2 Mbit program/cache and 1 Mbit dual-access data memory.
• Peripheral Interface: Includes three Multichannel Buffered Serial Ports (McBSPs), two 32-bit timers, a 4-channel DMA controller, and a 32-bit Expansion Bus (XBus).
• External Memory Interface: Glueless 32-bit EMIF supporting synchronous (SDRAM/SBSRAM) and asynchronous (SRAM/EPROM) memories.

Digital Signal Processor Dsp Applications

• Multichannel audio and video processing systems
• Wireless infrastructure base stations
• Industrial motor control and automation
• Test and measurement equipment

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'GNZ250' corresponds to the 352-pin BGA package and 250 MHz speed grade against the manufacturer's current datasheet SPRS104I. Confirm that the 1.5 V core voltage requirement aligns with the system power supply design, as this differs from the 1.8 V core voltage of the non-B C6202 variant. Ensure ESD precautions are taken due to the BGA package type.

Digital Signal Processor Dsp Selection Notes

Select the TMS320C6202BGNZ250 when 250 MHz performance and 352-pin packaging are required. Note that the C6202B series uses a 1.5 V core voltage, whereas the standard C6202 uses 1.8 V; ensure power sequencing supports this difference. Compare pin compatibility with the C6203B GNZ package if higher memory capacity is needed later. Verify PLL multiplier options available for the GNZ package (x1, x4, x8, x10) against system clock requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6000 platform, specifically the C62x fixed-point DSP generation. It is pin-compatible with the TMS320C6203B in the GNZ package, allowing for potential migration to devices with larger on-chip memory without redesigning the PCB footprint. It shares architectural similarities with the C6204 but offers more McBSP peripherals.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6203BGNZ250 is a pin-compatible alternative within the same package offering increased on-chip memory. The TMS320C6202 (non-B) is functionally similar but requires a 1.8 V core voltage instead of 1.5 V. Cross-referencing with the C6204 GLW package is possible for board layout reuse, though pin counts differ slightly due to additional power/ground balls in the GLS/GNY packages.
