Procurement Notes

Verify the specific suffix 'AABT' corresponds to the tape and reel packaging configuration required for automated assembly lines. Confirm that the AEC-Q100 automotive qualification status meets the target application's reliability standards. Ensure compatibility with the intended operating temperature range of -40°C to +105°C. Cross-reference the datasheet revision date to confirm current pinout and electrical specifications.

Selection Notes

Select this component when automotive certification is mandatory alongside high-speed Ethernet connectivity. Compare against the ATSAMV71Q21 variant if larger flash memory capacity is required. Consider the LQFP-144 package constraints regarding PCB space and thermal dissipation. Evaluate peripheral availability, specifically the number of available UART and SPI channels, against system design requirements.
