TMS320C6457CCMH8

Digital Signal Processor Dsp Overview

The TMS320C6457CCMH8 is a fixed and floating-point digital signal processor from the Texas Instruments C6000 DSP family. It features a single C64x+ core operating at a maximum clock frequency of 800 MHz. The device integrates 128 Kbytes of L1 program cache, 128 Kbytes of L1 data cache, and 1 Mbyte of L2 memory, which can be configured as SRAM or cache. It includes two serial real-time interfaces (SRIO) for high-speed communication with other processors or peripherals.

Digital Signal Processor Dsp Feature Summary

• Single C64x+ VLIW DSP core with 800 MHz maximum frequency

• Industrial automation and control systems

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'CCMH8' against the manufacturer's official datasheet to confirm pinout, package dimensions, and electrical characteristics. Ensure compatibility with existing board designs regarding voltage levels and thermal requirements before procurement.

Digital Signal Processor Dsp Selection Notes

Select this component when a single-core solution with integrated SRIO is required for low-latency inter-processor communication. Compare against multi-core variants like the C6657 if higher throughput is needed. Verify that the 800 MHz speed grade meets the system timing constraints.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C6457 series, designed for applications needing high computational density in a compact form factor. It serves as a bridge between legacy C64x designs and newer multi-core architectures, offering a cost-effective upgrade path for single-channel processing tasks.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements may include other C6457 variants with different speed grades or package options. Cross-referencing with the C6455 or C6459 is possible if performance requirements differ, but pin-to-pin compatibility must be verified via official substitution guides.
