Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging and environmental specifications. Confirm that the LQFP-100 package aligns with your PCB footprint requirements. Check for moisture sensitivity levels and reflow soldering profile compliance before integration. Ensure supply chain authenticity through authorized Microchip distributors to avoid counterfeit components.

Selection Notes

Select this model when dual-core processing capability is required alongside robust security features. Compare against single-core variants if computational load exceeds Cortex-M4 capabilities. Consider pin count constraints as the LQFP-100 limits available I/O lines. Evaluate memory requirements against the 2 MB Flash and 256 kB RAM allocation for application firmware storage.

Part Context

This component belongs to the SAM4CM series, which focuses on smart energy solutions. It complements other SAM4C family members by offering dual-core performance. The series targets applications demanding both high processing speed and integrated security functions without external crypto modules.

Replacement Considerations

ATSAM4CMP32CB-AUR serves as a reel-pack alternative. ATSAM4CMS32CB-AUR offers similar memory but lacks the dual-core configuration.
