Procurement Notes

Verify the specific suffix ACLZWT against the manufacturer's datasheet to confirm pinout and electrical specifications. Ensure compatibility with required core and I/O voltage levels (1.05V/1.20V and 1.8V/3.3V). Confirm that the 361-NFBGA package footprint matches the design layout. Check RoHS compliance status and moisture sensitivity level (MSL 3) for assembly process requirements.

Selection Notes

Select this component when a fixed-point C64x+ DSP core is required for video or audio processing tasks. The integrated 10/100 Ethernet MAC simplifies network connectivity designs compared to discrete solutions. Consider the 400MHz performance limit and 240kB RAM capacity for algorithm complexity. Verify thermal management needs given the 90°C junction temperature rating.
