It features a dual-core ARM Cortex-M4/M4F architecture operating at a maximum frequency of 120 MHz. The device integrates 512 KB of embedded Flash memory and 128 KB of SRAM. It is housed in a 100-LQFP package with 52 available I/O lines. The unit supports an operating voltage range of 1.62 V to 3.6 V and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-core processing capability combining ARM Cortex-M4 and M4F cores for enhanced computational performance.
• Integrated cryptographic engine supporting secure data handling and authentication protocols.
• Built-in Multi-Ring Lock Controller (MRLC) for granular memory protection and security isolation.

Applications

• Industrial control systems requiring high reliability and secure communication
• Medical devices needing robust data integrity and processing power
• Smart metering infrastructure with encryption requirements

Procurement Notes

Verify the specific suffix 'AUT' against official Microchip documentation to confirm it denotes the industrial temperature grade (-40°C to +85°C) and tray packaging variant. Ensure compatibility with existing design files, as package dimensions and pinouts must match the target PCB footprint precisely before procurement.

Selection Notes

Select this component when a dual-core ARM Cortex-M4 solution with integrated hardware security features is required. It is suitable for applications demanding high-speed processing alongside strict data protection standards. Compare RAM and Flash capacities against application memory needs to ensure sufficient resources for complex firmware execution.

Part Context

This part belongs to the SAM4CM family, which targets high-performance embedded applications. The series is characterized by its dual-core architecture and advanced security peripherals. It serves as a successor to earlier SAM4S and SAM4L lines, offering increased processing throughput and dedicated cryptographic acceleration for modern IoT and industrial use cases.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the SAM4CM or SAM4S families. Verify that any substitute maintains identical core specifications, memory sizes, and security feature sets to ensure functional parity without redesigning the hardware interface.
