Procurement Notes

Verify the specific suffix 'ANT' corresponds to the TQFP-64 package and 105°C temperature grade in official Microchip documentation before procurement. Confirm that the ordering information matches the required pinout and thermal specifications for your design. Ensure compatibility with existing supply chain channels for this specific variant.

Selection Notes

Select this model when a 48 MHz Cortex-M0+ MCU with 64 kB Flash and 38 I/Os is required. It is suitable for designs needing AEC-Q100 compliance and wide operating temperatures. Compare against other ATSAMC21 variants if different memory sizes or package types are needed.

Part Context

This component belongs to the ATSAMC21 family of low-power ARM microcontrollers. The G-series typically denotes specific pin counts and peripheral sets within the lineup. It shares architectural similarities with other SAMD and SAMC devices but offers distinct automotive-grade reliability features.

Replacement Considerations

Check for direct substitutes like ATSAMC21G16A-AUT (85°C) or ATSAMC21G16A-MNT (VQFN-48 package). Verify pin-to-pin compatibility and software library support before swapping packages or temperature grades.
