Procurement Notes

Verify the specific suffix AUT indicates automotive qualification status against the official Microchip datasheet. Confirm the EFP package designation matches the required 64-TQFP footprint for PCB layout. Ensure compatibility with the target operating voltage range of 1.71V to 3.63V. Check for any recent Product Change Notifications regarding assembly sites or materials that may affect certification requirements.

Selection Notes

Select this component when automotive compliance and robust industrial performance are required. The 256KB Flash size suits applications needing moderate code storage without external memory. The inclusion of Ethernet and USB interfaces reduces bill-of-materials complexity for connected devices. Consider the 120MHz processing speed adequate for real-time control loops involving sensor data acquisition and actuation.

Part Context

This part belongs to the SAM E53 series, designed for cost-sensitive yet feature-rich embedded applications. It shares architectural similarities with other SAM E5x variants but offers specific memory and pin configurations tailored for compact designs. The series emphasizes low power consumption while maintaining high performance through optimized instruction sets and peripheral efficiency.

Replacement Considerations

ATSAME53J18A-AU provides identical electrical specifications but utilizes tray packaging instead of tape and reel.
