Procurement Notes
Verify the specific ordering suffix 'T' indicates Tape & Reel packaging versus blank suffix for Tube or Tray. Confirm the 'I' suffix corresponds to the Industrial temperature range (-40°C to +85°C). Ensure the datasheet version matches the required revision for accurate pinout and electrical specifications.
Selection Notes
Select this model for designs requiring vertical migration within the AVR DD Family without code modification. Consider the 32-pin TQFP package for board space constraints. Evaluate the 24 MHz performance against power consumption requirements in the 1.8V to 5.5V operating range.
Part Context
This component belongs to the AVR16/32DD28/32 series, which shares pin and feature compatibility for easy migration. The AVR DD Family utilizes the latest Microchip technologies, offering a flexible architecture with low-power capabilities and advanced digital peripherals compared to previous generations.
