Procurement Notes

Verify the specific suffix 'AUR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the industrial temperature grade aligns with your operational environment specifications. Ensure compatibility with existing design-in tools and reference designs provided by the manufacturer for the SAM4S family to streamline development cycles.

Selection Notes

Select this component when large code storage and significant RAM are necessary for complex firmware or operating systems. The inclusion of an Ethernet MAC distinguishes it from lower-end SAM4S variants lacking native network interfaces. Consider the 100-pin package constraints regarding PCB space and pin availability compared to smaller footprint alternatives in the same series.
