Procurement Notes

Verify the specific suffix 'AU' confirms the lead-free, halogen-free RoHS-compliant variant in the 100-LQFP package. Confirm the presence of the cryptographic module and MRLC designation matches project security requirements. Check manufacturer documentation for current moisture sensitivity level classifications and recommended reflow soldering profiles to ensure proper handling during assembly processes.

Selection Notes

Select this component when dual-core processing is necessary for separating real-time tasks from complex application logic. The inclusion of hardware cryptography makes it suitable for secure boot and data protection scenarios. Ensure the design accommodates the 1.62 V to 3.6 V supply range and utilizes the available 52 general-purpose I/O pins for system connectivity.

Part Context

This part belongs to the Microchip SAM4CM family, designed for high-performance applications needing robust processing power alongside security features. The SAM4CM series distinguishes itself with dual-core Cortex-M4 configurations and extensive peripheral sets, positioning it above single-core variants like the SAM4C for demanding industrial and commercial control environments.

Replacement Considerations

Consult official substitution lists for compatible parts within the SAM4CM family. Verify pinout compatibility and memory size equivalence before replacing components in existing designs.
