Procurement Notes

Verify the specific suffix 'ANT' against official Microchip documentation to confirm pinout compatibility and temperature grade. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential design changes.

Selection Notes

Select this component when a 48 MHz Cortex-M0+ solution with moderate I/O count is required. Compare pin counts and memory sizes against alternative SAM D20 variants like the ATSAMD20J or ATSAMD20E series. Verify that the 1.62 V to 1.95 V supply range aligns with your system power architecture before finalizing the design.
