Procurement Notes

Verify the specific suffix 'MNT' corresponds to the 48-QFN package and the -40°C to +105°C temperature range during sourcing. Confirm AEC-Q100 compliance status if automotive application is intended. Ensure compatibility with existing firmware libraries designed for the SAM D21 family. Check for any recent production change notices affecting pinout or electrical characteristics.

Selection Notes

Select this model when functional safety standards are required alongside standard MCU performance. The QFN package suits space-constrained designs. Consider the 48MHz speed limit for real-time processing needs. Evaluate the 1.62V minimum voltage against system power rails. Compare peripheral counts against alternative SAM D21 variants if more I/O or memory is needed.

Part Context

This component belongs to the Microchip SAM D21G series, which emphasizes functional safety features. It shares the Cortex-M0+ architecture with other SAM D21 models but distinguishes itself through FuSa certification and AEC-Q100 qualification. The 'L' suffix typically denotes the extended temperature range, while 'MNT' specifies the QFN-48 packaging option.
