Procurement Notes

Verify the specific suffix 'CUR' against official Microchip documentation to confirm the tape-and-reel packaging configuration, as datasheets may primarily reference tray packages like 'CU'. Ensure compatibility with moisture sensitivity level requirements during assembly. Confirm that the 100-TFBGA footprint matches your PCB design constraints. Cross-reference the latest errata sheet for any known silicon revisions affecting electrical characteristics or peripheral functionality before finalizing procurement.

Selection Notes

Select this component when a balance of high-performance computing and low power consumption is required for embedded designs. The 100 MHz Cortex-M4 core suits applications needing real-time processing capabilities. Consider the 1 MB Flash capacity for complex firmware storage needs. Evaluate the 100-pin TFBGA package size against available board space. Verify that the 1.62 V to 3.6 V supply range aligns with your system's power architecture.
