Procurement Notes

Verify the specific suffix 'AN' against the official Microchip datasheet to confirm package type and temperature grade. Ensure compatibility with existing board layouts regarding pin assignments and power requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when both Ethernet connectivity and USB OTG capabilities are required alongside significant program storage. Compare RAM sizes and peripheral counts against alternative SAM4E variants to ensure optimal cost-performance balance. Consider thermal management solutions suitable for the LQFP package if operating near maximum temperature limits.

Part Context

This MCU belongs to the SAM4E series, designed for applications demanding robust connectivity and processing power. It shares architectural similarities with other SAM4E parts but offers specific memory and peripheral configurations tailored for complex embedded tasks. The series emphasizes low power consumption while maintaining high performance through the Cortex-M4 core.

Replacement Considerations

Check for direct substitutes within the SAM4E family such as ATSAM4E16EA or ATSAM4E16CA, ensuring pin-to-pin compatibility and equivalent memory specifications. Verify that any replacement maintains support for required interfaces like Ethernet and USB.
