Procurement Notes

Verify the specific suffix 'AU' against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required operating temperature range and voltage supply constraints for your target application environment before finalizing procurement orders.

Selection Notes

Select this component when automotive qualification is mandatory alongside high-speed Ethernet or CAN FD connectivity. The 128-TQFP package provides extensive I/O availability for complex peripheral integration. Consider power consumption profiles and thermal dissipation requirements relative to the 120 MHz operational speed during system design.

Part Context

This part belongs to the SAM E54 family, which targets safety-critical and connected applications. The series emphasizes secure boot capabilities and robust peripheral sets suitable for demanding environments. It complements other Microchip solutions by offering integrated security hardware and high-performance processing in a single package.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the SAM E54 or SAM D5x families. Verify functional equivalence regarding memory size, interface availability, and automotive certification status before implementing any cross-reference.
