IoT gateways with USB connectivity

Procurement Notes

Verify the specific suffix 'AU' indicates automotive grade qualification and 'EFP' denotes the TQFP-64 package configuration. Confirm RoHS compliance status and check for any recent Product Change Notifications (PCNs) regarding assembly sites or packaging materials. Ensure the source document explicitly lists this exact part number to avoid confusion with non-automotive variants like the ATSAMD51 series.

Selection Notes

Select this component when automotive certification is mandatory for the application. The combination of 512 KB Flash and 192 KB RAM supports complex firmware requirements. The TQFP-64 package provides a balance of pin count and board space. Verify that the 1.71 V to 3.63 V supply range aligns with the system power design.

Part Context

This microcontroller belongs to the SAM E51 family, which is designed for high-performance embedded applications. It shares architectural similarities with the SAM D51 but adds automotive qualification. The family emphasizes security features and low-power operation alongside high-speed processing capabilities for demanding industrial and automotive environments.
