Procurement Notes
Verify the specific suffix 'AUR' indicates tape-and-reel packaging when sourcing components. Confirm that the part number corresponds to the 128KB flash variant within the SAM4S family. Ensure compatibility with required voltage levels and interface configurations for the target application design.
Selection Notes
Select this component for applications requiring USB connectivity combined with moderate code storage needs. Compare against other SAM4S variants if larger memory or different pin counts are necessary. Consider the LQFP-64 package constraints for PCB layout and thermal management during the design phase.
Part Context
This microcontroller belongs to the SAM4S series, designed for performance-oriented embedded applications. It shares architectural similarities with other SAM4S parts but differs in memory size and package options. The series targets cost-sensitive markets requiring ARM Cortex-M4 capabilities.
Replacement Considerations
Direct substitutes include other ATSAM4S2xx variants with compatible pinouts and memory sizes. Verify electrical specifications and software compatibility before replacing existing designs with alternative packages or speed grades.
