Procurement Notes

Verify the specific suffix AN corresponds to the 64-TQFP package configuration when sourcing. Confirm that the supply voltage requirements align with the target circuit design, as the datasheet indicates specific voltage ranges for different operational domains. Ensure compatibility with existing development tools such as Atmel-ICE for programming and debugging during the procurement phase.

Selection Notes

Select this component for designs requiring a balance of processing speed and low power consumption. The 48 MHz clock speed and extensive peripheral set make it suitable for complex control tasks. Consider the 64-TQFP package for through-hole or surface-mount assembly needs. Evaluate the 12-bit ADC resolution against sensor accuracy requirements before finalizing the selection.
