Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status and check for obsolescence notices, as this specific part number may be discontinued. Ensure packaging integrity matches reel, cut tape, or MouseReel specifications required for your assembly process. Validate that the suffix AUR corresponds to the correct environmental and packaging configuration.

Selection Notes

Select this MCU when a single-core Cortex-M4 solution with integrated security features is required. Compare against the dual-core ATSAM4C series if higher processing throughput is needed. Consider the ATSAM4S series for cost-sensitive applications without advanced security requirements. Verify that the 1.08V to 1.32V supply range aligns with your system power design constraints.

Part Context

This component belongs to the SAM4CM family, designed for smart energy and industrial applications. It differs from the dual-core SAM4C series by utilizing a single processor core. The SAM4CM line emphasizes security integration and efficiency for metering and control tasks within the broader Microchip ARM-based microcontroller portfolio.
