Procurement Notes
Verify the specific suffix 'AU' corresponds to the lead-free, RoHS-compliant LQFP-100 package variant. Confirm the manufacturing date code and lot traceability requirements against your assembly standards. Ensure the component status is active or note any obsolescence notices from Microchip Technology before finalizing procurement plans.
Selection Notes
Select this model when dual-core processing power and large memory capacity are required for complex firmware. The SAM4CM series is suitable for designs needing hardware-accelerated cryptography. Compare pin counts and memory sizes against other SAM4C variants if I/O density or cost constraints differ.
Part Context
This component belongs to the Microchip SAM4CM family, designed for high-performance embedded applications. It extends the SAM4C line with enhanced memory and security features. The dual-core design allows separation of real-time control tasks from communication protocols.
Replacement Considerations
Compatible substitutes within the same family include ATSAM4CMS32CA-AU and ATSAM4CMS32CC-AU. Verify package compatibility and memory configuration matches before substitution.
