Procurement Notes

Verify the specific suffix ANT corresponds to the TQFP-48 package and 105°C industrial temperature grade. Confirm AEC-Q100 automotive qualification status matches project requirements. Check moisture sensitivity level (MSL) handling instructions due to humidity sensitivity classification. Ensure compatibility with existing PCB footprint designs for the TQFP-48 form factor before finalizing procurement orders.

Selection Notes

Select this model when a 48 MHz Cortex-M0+ MCU with 128 kB Flash and 16 kB SRAM is required. It is suitable for designs needing 38 general-purpose I/Os and support for 5V logic levels within a 2.7V to 5.5V range. Consider this part for automotive or industrial applications demanding AEC-Q100 reliability and extended temperature operation up to 105°C.

Part Context

This component belongs to the ATSAMC21 family of 32-bit ARM Cortex-M0+ microcontrollers. The G17 variant specifically denotes the configuration with 128 kB of Flash memory and 16 kB of SRAM. The ANT suffix indicates the TQFP-48 packaging option with an extended industrial temperature range capability, distinguishing it from other package or temperature variants within the same silicon family.

Replacement Considerations

Cross-reference with other ATSAMC21GxxA variants for pin-compatible upgrades or downgrades based on memory size requirements. Verify that alternative packages such as QFN maintain the necessary I/O count for the specific application design constraints.
