Digital Signal Processor Dsp Procurement Notes

Verify the specific silicon revision and temperature grade required for the application. Confirm that the 176-pin PTP package matches the PCB footprint. Ensure power supply rails are compatible with the 1.2V or 1.3V core voltage requirements specified in the datasheet.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-performance floating-point processing with low power consumption. The C6745 lacks the 128KB shared RAM and LCD controller found in the C6747 variant; verify peripheral availability against system requirements. The USB interface supports Full-Speed only, unlike the High-Speed capability of the C6747.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C674x family, which is code-compatible with the C6000 DSP platform. It combines the performance of the C64x+ core with the floating-point capabilities of the C67x+ core. The 'B' suffix typically denotes a specific temperature range or revision within the commercial/industrial product line.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6747 is a pin-compatible alternative with additional features including 128KB shared RAM, LCD controller, and High-Speed USB support. Other C6000 series processors may require significant architectural changes due to instruction set or memory map differences.
