Procurement Notes

Verify the specific suffix 'D' indicates Functional Safety compliance when sourcing. Confirm package integrity for the 48-TQFP form factor. Check RoHS3 status against current environmental regulations. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity level 3 classification.

Selection Notes

Select this component for designs requiring certified functional safety standards within the SAM D21 family. Compare RAM and Flash capacities against alternative models like the ATSAMD21G16 series if storage requirements differ. Verify that the 48MHz clock speed meets real-time processing needs. Ensure the 48-TQFP package fits the available PCB footprint constraints.

Part Context

This part belongs to the SAM D21G series, which focuses on low-power performance with functional safety certifications. It shares the same core architecture as other SAM D21 variants but distinguishes itself through its specific memory configuration and safety qualifications. The series targets cost-sensitive embedded applications requiring reliable operation in harsh environments.

Replacement Considerations

ATSAMD21G17A-AU serves as a direct substitute with identical specifications except for potential minor manufacturing lot variations.
