Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm package type and temperature rating. Ensure the ordering part number matches the required tape-and-reel or tray packaging configuration. Cross-reference the datasheet revision date to confirm current errata status before finalizing procurement specifications.
Selection Notes
Select this component when a low-cost, low-power 32-bit MCU is required for basic control tasks. It is suitable for applications needing moderate processing speed and limited memory resources. Compare pin compatibility and peripheral availability against other SAM D20 variants if system constraints require different I/O counts or memory sizes.
Part Context
This microcontroller is part of the SAM D20E family, designed for cost-sensitive applications requiring ARM Cortex-M0+ performance. It shares architectural similarities with other SAM D2x series devices but offers specific memory and peripheral configurations tailored for entry-level embedded projects.
Replacement Considerations
Consult the SAM D20 Family Complete Datasheet for verified pin-compatible alternatives within the same series. Substitutes may include other SAM D20E variants with differing memory capacities or package options.
