Procurement Notes

Verify the specific suffix 'MUT' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the voltage grade and temperature range align with the target application environment specifications before finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate program storage and extensive analog input channels is required. It is suitable for designs needing multiple serial interfaces without external level shifters. Consider pin count constraints as the 48-pin package limits available general-purpose I/O compared to larger footprints.

Part Context

This part belongs to the Microchip SAM D20 family, which targets cost-sensitive embedded applications. The series emphasizes low power consumption and ease of use through compatible software frameworks. It serves as a bridge between basic 8-bit controllers and more complex 32-bit architectures.
