Procurement Notes

Verify the ordering suffix 'T' indicates Tape & Reel packaging and 'I' denotes the Industrial temperature range (-40°C to +85°C). Confirm the 'PT' suffix corresponds to the TQFP package style. Ensure compatibility with the AVR DA family pinout if migrating from other variants within the series.

Selection Notes

Select this component for designs requiring vertical migration within the AVR DA family without code modification. It is suitable for applications needing high I/O counts (55 pins) and extensive analog capabilities. Consider the 128 KB Flash size for complex firmware requirements and the 24 MHz operating speed for real-time processing tasks.
