Digital Signal Processor Dsp Procurement Notes

Verify that the ordering suffix 'A05' corresponds to the 50-MHz speed grade and 1.05-V core voltage specification. Confirm the package type matches the 144-terminal BGA Microstar Array (ZHH suffix) required for the target PCB footprint.

Digital Signal Processor Dsp Selection Notes

Select this part over higher-speed variants if the application requires operation at 50 MHz with a 1.05-V core supply. Ensure the design accommodates the specific power domains, including isolated analog, RTC, CPU, and peripheral supplies, as well as the integrated LDOs for DSP, analog, and USB sections.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C553x series, which shares the same 144-pin BGA package and base architecture. The primary distinction lies in memory capacity and peripheral availability; the C5535 offers the highest memory configuration within the series, including the full 256 KB SARAM block and the LCD bridge interface.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C5535AZHHA05 serves as a direct functional replacement, differing only in the operational temperature range extension to -40°C to 85°C while maintaining identical electrical and pinout specifications.
