Procurement Notes

Verify component authenticity through authorized distributors as this part is marked Not Recommended for New Designs. Confirm package integrity upon receipt, specifically checking for TQFP-100 pin alignment. Ensure design reviews account for the discontinued status when planning long-term production support. Cross-reference datasheet revisions to confirm electrical characteristics match current requirements.

Selection Notes

Select this component for designs requiring high-speed 8-bit processing with integrated analog front-end capabilities. The 100-pin TQFP package provides extensive I/O options suitable for complex peripheral integration. Consider the 100 MIPS performance for real-time control loops. Evaluate power consumption against available supply voltages between 3.0 V and 3.6 V. Review memory constraints to ensure 64 kB Flash and 8448 bytes RAM suffice for application code and data storage.
