Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix ZWT6 against the manufacturer's datasheet to confirm pinout compatibility and electrical characteristics. Confirm that the required 600 MHz performance aligns with system timing constraints. Ensure the 361-NFBGA footprint matches the PCB design. Check current availability status as lead times may vary by region.

Digital Signal Processor Dsp Selection Notes

Select this model when a C64x+ core with 600 MHz speed is required in a compact 361-ball BGA package. Compare against the TMS320C6421ZDUL if a 376-pin BGA or lower 400 MHz speed is acceptable. Verify power supply requirements for the 1.05V-1.20V core and 1.8V/3.3V I/O domains before integration.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C642x family of fixed-point DSPs. It shares architectural similarities with other variants like the TMS320C6424 but differs in packaging and specific interface configurations. The ZWT6 designation indicates the 361-NFBGA package variant within the broader C6421 product line.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6421ZDU4 is a related variant using a 376-BGA package. Cross-referencing is necessary due to pin count differences. Other C642x family members may offer different speeds or packages but require schematic and software verification.
