Procurement Notes
Verify the specific suffix 'AUTR' against official Microchip documentation to confirm tape-and-reel packaging status and exact temperature grade. Ensure compatibility with existing PCB footprints for the LQFP-100 package. Cross-reference the full part number with current datasheets to validate pinout and electrical characteristics before procurement.
Selection Notes
Select this component when dual-core processing capabilities are required alongside robust security features. The 2 MB Flash and 512 KB RAM provide ample storage for complex firmware and data logging. Consider the 120 MHz performance for real-time control tasks. Verify that the LQFP-100 package fits the mechanical constraints of the design.
Part Context
This part belongs to the SAM4CM family, designed for smart energy and industrial markets. It builds upon previous generations with enhanced security and memory capacity. The dual-core design allows separation of critical security functions from general application logic, improving system integrity and performance efficiency.
Replacement Considerations
Consult Microchip's official cross-reference tools for verified substitutes. Generic MCU replacements may not support the specific dual-core architecture or cryptographic hardware acceleration required by this model.
