Procurement Notes

Verify the specific suffix 'AUR' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 100-LQFP footprint matches your PCB design constraints. Ensure compatibility with the 1.62V to 3.6V power supply rails in your target application circuitry before finalizing procurement decisions.

Selection Notes

Select this component when a balance of processing power and peripheral richness is needed within a 100-pin form factor. The SAM4S series offers a cost-effective solution compared to higher-end models while maintaining compatibility with the Advanced Software Framework. Consider the 120MHz clock speed sufficient for real-time control loops requiring moderate computational complexity.

Part Context

This part belongs to the Microchip SAM4S family, designed for general-purpose embedded applications. It shares architectural similarities with other SAM4 variants but distinguishes itself through its specific memory configuration and pin count. The series targets markets demanding reliable performance in compact designs without sacrificing interface versatility or processing capability.

Replacement Considerations

ATSAM4S8BA-AUR provides similar functionality in a smaller 64-pin LQFP package with reduced I/O count. ATSAM4S16CA-AUR offers increased flash capacity while retaining the same 100-LQFP footprint and core specifications. Evaluate pin compatibility and memory requirements when considering these alternatives.
