Procurement Notes

Verify the specific suffix 'MUT' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the functional safety certification status aligns with the target application's safety integrity level requirements. Ensure the 48-QFN package footprint matches the PCB design specifications. Check for any regional compliance certifications relevant to the deployment location.

Selection Notes

Select this component when a Functional Safety (FuSa) certified MCU is required within the SAM D21 family. It is suitable for designs needing 128 KB of program memory and robust analog input capabilities. Consider this part over non-certified variants if system safety standards mandate FuSa compliance. Evaluate the 48 MHz processing speed against real-time control loop requirements.

Part Context

This microcontroller is part of the Microchip SAM D21G series, which focuses on low-power performance combined with functional safety features. The series targets applications where reliability and safety are paramount, such as automotive and industrial sectors. The ATSAMD21G17A-MUT variant specifically offers the QFN package option, providing a compact solution for space-constrained designs while maintaining full peripheral functionality.

Replacement Considerations

ATSAMD21G17A-MU: Identical electrical specifications but in a tray package instead of tape and reel.
