Procurement Notes

Verify the specific package marking and date code against the official datasheet revision DS40002498A. Confirm that the 'E' suffix corresponds to the extended temperature range (-40°C to +125°C) and the 'T' indicates tape and reel packaging. Ensure compatibility with the UPDI programming interface requirements specified in the hardware guidelines section.

Selection Notes

Select this component when vertical migration within the AVR EA family is required without code modification. It is suitable for designs needing 48 pins with extensive I/O capabilities and advanced analog features. Consider the 20 MHz maximum frequency and 1.8 V to 5.5 V operating voltage range for power budgeting.

Part Context

This part belongs to the AVR16EA28/32/48 series within the broader AVR EA Family. It shares pin and feature compatibility with other members of the family, allowing for horizontal migration to lower pin counts or vertical scaling to higher memory variants like the AVR32EA48 or AVR64EA48.
