Procurement Notes

Verify the specific suffix 'MN' against official Microchip documentation to confirm the exact package type and temperature grade. Ensure compatibility with design-in requirements regarding pinout and electrical specifications before ordering.

Selection Notes

Select this model when a 64-pin QFN package is required for space-constrained designs. Consider the 2.7V-5.5V operating range for flexibility in power supply architectures compared to lower-voltage variants.

Part Context

This part belongs to the SAM D20J series, designed for cost-sensitive applications requiring moderate performance. It shares architectural similarities with other SAM D20 models but differs in pin count and peripheral availability.

Replacement Considerations

Check datasheet errata for silicon revisions. Verify pin-to-pin compatibility with alternative packages in the same series if form factor changes are permissible.
