The figure below shows the AVR® DA devices, laying out pin count variants and memory sizes:
- Vertical migration is possible without code modification, as these devices are fully pin and feature compatible
- Horizontal migration to the left reduces the pin count, and therefore, the available features

DA Family
Overview
Devices with different Flash memory sizes typically also have different SRAM.
The name of a device in the AVR® DA family is decoded as follows:
