Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and '6LX' indicates the VQFN48 package style. Confirm the 'T' suffix denotes tape and reel packaging if required for automated assembly. Ensure compatibility with the specific voltage requirements of your application within the 1.8V to 5.5V operating range.

Selection Notes

Select this component when vertical migration within the AVR DA family is needed without code modification. It is suitable for designs requiring high pin counts and extensive analog capabilities in a compact VQFN48 footprint. Consider the extended temperature rating for harsh environments. Evaluate the trade-off between the 24 MHz maximum frequency and power consumption against other family members like the AVR64DA series.

Part Context
