TMS320C6655CZH25

Digital Signal Processor Dsp Overview

The TMS320C6655CZH25 is a fixed and floating-point digital signal processor from the Texas Instruments TMS320C6655 series. It features a single C66x DSP core with maximum clock frequencies of 1 GHz or 1.25 GHz. The device includes 32 kB L1 instruction cache and 32 kB L1 data cache per core. It operates on a supply voltage range of 900 mV to 1.1 V and is housed in a 625-pin FCBGA package (BGA625, 25x25, 32). The component supports boundary scan and utilizes a multiple internal bus architecture.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix against the manufacturer's datasheet to confirm the exact clock frequency rating (1 GHz vs 1.25 GHz) and temperature grade. Ensure the ordering part number matches the required package variant and RoHS compliance status as listed in official component documentation.

Digital Signal Processor Dsp Selection Notes

Select this model when a single-core solution with integrated L1 caching is sufficient for the application load. Compare against multi-core variants in the TMS320C6655 family if higher throughput is required. Confirm that the 625-pin FCBGA footprint aligns with the PCB design constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6655 series within the broader C6000 DSP platform. It shares architectural similarities with other members like the TMS320C6657 but differs in core count and specific peripheral configurations. The series is designed for scalable hardware and software platforms across automotive and industrial sectors.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes include other variants within the TMS320C6655 family such as the TMS320C6655CZHA25, provided the pinout and electrical specifications are compatible. Cross-model comparisons should be made based on core count and cache size requirements.
