Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'T' indicates tape and reel packaging. Confirm the specific pinout and peripheral availability for the 32-pin variant against the official datasheet DS40002443A before finalizing procurement specifications.

Selection Notes

Select this component when vertical migration within the AVR EA family is required without code modification. Choose this part if extended industrial temperature operation is necessary alongside high-performance analog features. Ensure the design utilizes the UPDI interface for programming and debugging requirements.

Part Context

This device belongs to the AVR64EA28/32/48 series, which shares a common core and peripheral set across different pin counts. The 32-pin version offers a balance between feature density and footprint size compared to the 28-pin and 48-pin variants in the same family.
