Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package dimensions and pinout compatibility. Ensure that the ordering information matches the required tape and reel or cut tape specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with assembly processes.

Selection Notes

Select this component when high-speed execution combined with large memory capacity is necessary. The 144-pin LFBGA package offers significant I/O availability for complex system integration. Consider the internal oscillator type and voltage ranges when designing power management circuits. Evaluate the need for external memory interfaces if additional storage beyond the integrated Flash is required.
