Procurement Notes
Verify the specific suffix 'AUR' against official Microchip documentation to confirm tape-and-reel packaging status, as datasheets may list 'AU' variants. Confirm RoHS compliance and REACH status through current manufacturer declarations. Ensure compatibility with existing PCB footprints for the 100-LQFP package before procurement.
Selection Notes
Select this component when dual-core processing is required alongside robust security features. Compare memory sizes and peripheral availability against similar SAM4CM series parts. Verify that the 120 MHz speed and 1.62V minimum voltage align with system power and timing requirements. Check for alternative packages if pin count or form factor constraints exist.
Part Context
This part belongs to the SAM4CM series of ARM-based microcontrollers designed for high-performance applications. It shares architectural similarities with other SAM4C and SAM4CM variants but offers specific memory configurations and interface options tailored for complex embedded tasks. The series emphasizes security and efficiency for industrial and consumer markets.
Replacement Considerations
Consult Microchip's official cross-reference tools for verified substitutes. Potential alternatives within the SAM4CM family may offer different memory sizes or package types. Ensure any replacement maintains compatible pinouts and software support libraries.
