Procurement Notes

Verify the specific suffix 'MUT' against official Microchip documentation to confirm the tape and reel packaging configuration. Ensure the voltage grade matches the application requirements, as the datasheet specifies a narrow supply range. Confirm RoHS compliance status through the manufacturer's current environmental declarations before finalizing procurement orders.

Selection Notes

Select this model when a balance of moderate memory capacity and high pin count is required in a compact surface-mount package. Compare against other SAM D20 variants if fewer I/O pins or different memory sizes better suit the design constraints. Consider the TQFP-64 footprint availability during PCB layout planning to ensure compatibility with existing manufacturing equipment.
