- Consumer electronics utilizing USB connectivity features
- Medical devices needing precise analog-to-digital conversion
- Automotive instrumentation with extended temperature operation
Procurement Notes
Verify the specific suffix 'AU' confirms the 100-LQFP package and industrial temperature range during sourcing. Confirm RoHS compliance status matches current manufacturing standards. Check for any recent Product Change Notifications regarding assembly location or packaging updates. Ensure compatibility with existing PCB footprint designs before finalizing procurement orders.
Selection Notes
Choose this component when 128KB program memory and 64KB RAM suffice for application logic. Select for designs requiring high-speed 120MHz execution with low power consumption. Opt for this part if USB OTG functionality is necessary without external transceivers. Consider the 100-pin count for sufficient I/O availability in compact form factors.
Part Context
This MCU belongs to Microchip's SAM4S family, designed for performance-oriented embedded applications. It shares architectural similarities with other SAM4S variants but differs in memory size and package options. The series targets cost-sensitive markets while maintaining high computational throughput and rich peripheral sets for versatile system integration.
Replacement Considerations
ATSAM4S2CA-AR offers identical specifications in tape-and-reel packaging. ATSAM4S2BA-AU provides the same core performance in a different pin-compatible variant. Verify pinout and memory configuration matches when substituting with other SAM4S series members.
