TMS320C6657CZH

Digital Signal Processor Dsp Overview

The TMS320C6657CZH is a fixed and floating-point digital signal processor from Texas Instruments, housed in a 625-pin FCBGA package. It features two C66x DSP cores operating at frequencies up to 1.25 GHz, delivering 40 GMACs per core for fixed-point and 20 GFLOPS per core for floating-point performance. The device utilizes the KeyStone multi-core architecture with a non-blocking TeraNet switch structure. It includes integrated L1/L2 caches, a 1 MB MSM SRAM, and peripherals such as PCIe Gen2, SRIO 2.1, and Gigabit Ethernet.

Digital Signal Processor Dsp Feature Summary

• Dual C66x DSP cores with 1.25 GHz maximum frequency
• KeyStone multi-core architecture with TeraNet switch
• Integrated 1 MB MSM SRAM shared between cores
• Supports both fixed-point (40 GMACs/core) and floating-point (20 GFLOPs/core) operations

Digital Signal Processor Dsp Applications

• Test and measurement equipment
• Medical imaging systems
• Industrial automation
• Wireless infrastructure base stations

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix against the manufacturer's current product status, as availability may vary by region. Confirm RoHS compliance and lead times directly with authorized distributors or Texas Instruments. Ensure the package type matches the 625-FCBGA specification for PCB design compatibility.

Digital Signal Processor Dsp Selection Notes

Select this model when high-performance parallel processing is required for complex algorithms. Compare with the TMS320C6657CZHA25 if an extended industrial temperature range (-40°C to +100°C) is necessary, as the CZH variant typically supports commercial temperatures (0°C to 85°C). Evaluate memory requirements against the integrated 1 MB MSM SRAM.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C665x family of processors, which are designed for high-throughput applications. It is backward compatible with previous C6000 series software, allowing for code reuse. The device integrates hardware accelerators like Viterbi and Turbo decoders to offload CPU tasks.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6657CZHA25 is a verified alternative offering an extended temperature range. Other members of the C665x family, such as the single-core C6655, may be considered if lower performance is acceptable.
