The figure below shows the megaAVR® 0-series 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

0-series Overview
Devices with
different Flash memory sizes typically also have different SRAM and
EEPROM.
The name of a device in the megaAVR 0-series is decoded as follows:
