Procurement Notes

Verify current availability status as discontinuation notices may apply to specific suffixes or manufacturing sites. Confirm RoHS compliance and moisture sensitivity level requirements prior to procurement. Ensure compatibility with existing PCB footprints for the 208-PQFP package. Review latest Product Change Notices for assembly site updates or software toolchain modifications that may affect production readiness.

Selection Notes

Select this model when 36,000 system gates and 176 I/Os are required within a 208-pin form factor. Verify that the 5V core voltage aligns with the target system power rails. Consider the 208-PQFP package dimensions against available board space. Evaluate if the specific speed grade meets timing constraints for the intended clock frequencies. Check for necessary environmental certifications if deploying in automotive or military sectors.

Part Context
