Procurement Notes

Verify the specific suffix 'B' indicates extended temperature range compliance when sourcing. Confirm assembly site documentation against recent Product Change Notices to ensure manufacturing origin consistency. Cross-reference the datasheet revision history to validate pinout and electrical characteristics match your design requirements before finalizing procurement orders.

Selection Notes

Select this component when 512KB of program storage is required alongside full-speed USB functionality. It is suitable for designs needing both analog input/output capabilities and high-performance computing. Compare against lower-capacity SAM4S variants if cost or pin count constraints allow for reduced memory resources.

Part Context

This part belongs to the Microchip SAM4S series, which utilizes the ARM Cortex-M4 architecture. It succeeds earlier SAM3 series devices by offering higher clock speeds and enhanced peripheral sets. The series is designed for applications demanding a balance between processing power and peripheral richness in a compact form factor.

Replacement Considerations

ATSAM4S8BA-AN is a similar variant within the same family but may differ in temperature rating or packaging details. Verify exact electrical specifications and pin compatibility before substitution.
