TMS320C6457CCMH2

Digital Signal Processor Dsp Overview

The TMS320C6457CCMH2 is a fixed-point digital signal processor from the Texas Instruments C6000 DSP family. It features a single C64x+ CPU core operating at a maximum clock frequency of 800 MHz. The device integrates 128 Kbytes of L1 program cache and 128 Kbytes of L1 data cache, along with 512 Kbytes of L2 cache that can be configured as SRAM. Key interfaces include two Serial RapidIO (SRIO) ports, four EMIFs, and multiple McBSPs. It operates within a voltage range of 0.9 V to 1.1 V and supports an industrial temperature range of -40°C to +100°C in a 697-pin FCBGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'CCMH2' against the official datasheet to confirm pinout compatibility and thermal specifications. Ensure the procurement source provides valid RoHS compliance documentation. Check for any obsolescence notices or lifecycle status updates directly from Texas Instruments before finalizing orders.

Digital Signal Processor Dsp Selection Notes

Select this component when a single-core solution with high-throughput SRIO connectivity is required. Compare against the TMS320C6455 if lower power consumption is prioritized over the 800 MHz performance ceiling. Verify that the system design accommodates the 697-pin FCBGA footprint and the necessary 0.9V-1.1V power delivery network.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C645x series, designed for high-performance embedded signal processing. It shares architectural similarities with the C6455 but offers higher clock speeds and enhanced I/O options. The C64x+ core extends the original C64x ISA with SIMD instructions for improved multimedia and communications performance.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements may include other variants within the TMS320C645x family, such as the TMS320C6455, provided the clock speed requirements are met. Cross-referencing with the TMS320C6457B variant is necessary if higher frequencies are needed, though package and electrical characteristics must be validated.
