Procurement Notes

Verify the specific suffix 'AUT' confirms automotive-grade qualification and extended temperature range compliance. Confirm the 48-TQFP package type matches the target PCB footprint. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the manufacturer datasheet for any recent design changes or errata updates before finalizing procurement specifications.

Selection Notes

Select this model when 128 kB of Flash and 16 kB of RAM are sufficient for the application logic. Choose the 48-TQFP package if board space allows for through-hole compatible surface mounting. Consider alternative SAML22 variants if additional USB endpoints or higher pin counts are required. Verify that the 32 MHz processing speed meets real-time control requirements.
