Procurement Notes

Verify the specific suffix 'AN' against official Microchip documentation to confirm the exact package type (TQFP) and temperature grade. Ensure compatibility with design requirements for voltage range and pin count. Cross-reference datasheet revisions for any errata or functional updates prior to final procurement decisions.

Selection Notes

Select this component when a low-cost, low-power 32-bit MCU is required with moderate memory capacity. The TQFP-32 package suits designs needing through-hole or standard surface-mount assembly. Consider alternative packages like QFN if board space is constrained, ensuring the pinout remains compatible with the existing schematic.

Part Context

This part belongs to the SAM D20E family within the broader SAM D2x series. These microcontrollers are designed for cost-sensitive applications requiring ARM Cortex-M0+ performance. The E-series typically denotes specific memory configurations and package options within the product line, targeting industrial and consumer markets.

Replacement Considerations

Check for direct pin-compatible alternatives within the SAM D20 family, such as variants with different memory sizes or packages. Verify that any substitute maintains the same core architecture and peripheral set to ensure software compatibility.
