Procurement Notes
Verify the specific suffix 'AN' against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing board layouts by checking pin assignments and voltage levels. Cross-reference the datasheet revision date to confirm feature availability and errata status before finalizing procurement decisions.
Selection Notes
Select this component when a low-cost, low-power solution with sufficient processing power for simple tasks is required. Consider the available GPIO count and peripheral mix relative to system requirements. Evaluate power consumption profiles across different operational modes to ensure compliance with battery life expectations.
Part Context
This part belongs to the SAM D20 family of microcontrollers designed for cost-sensitive applications. It shares architectural similarities with other members of the series but offers specific memory configurations and peripheral sets tailored for entry-level embedded projects within the Microchip ecosystem.
Replacement Considerations
Consult official Microchip documentation for direct pin-to-pin compatible alternatives within the SAM D20 or SAM D21 families. Verify that any substitute maintains identical electrical characteristics and software compatibility to minimize redesign efforts.
