Procurement Notes
Verify the specific suffix 'MF' indicates the 48-QFN package and extended temperature range when sourcing. Confirm RoHS compliance status with the supplier. Ensure the source document matches the manufacturer's official datasheet for the SAM D21G family to validate pinout and electrical characteristics. Cross-reference the part number with Microchip's official database to confirm current production status.
Selection Notes
Select this component when a balance of moderate program memory and functional safety features is required. It is suitable for designs needing USB connectivity without external transceivers. Consider the QFN package constraints for thermal management and PCB layout. Compare against other SAM D21 variants if higher memory or different I/O counts are needed.
Part Context
This MCU is part of the SAM D21G family, designed for applications demanding functional safety integrity levels. It shares the core architecture with other SAM D21 devices but offers specific memory sizes and package options. The G-series typically targets industrial and automotive sectors where reliability and safety certification are paramount.
Replacement Considerations
ATSAMD21G17A-AU: Same core and memory, TQFP-48 package. ATSAMD21G17A-MUT: Same core and memory, QFN-48 package. Verify package dimensions and pin compatibility before substitution.
