1.3 megaAVR® 0-series
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.
Devices with different Flash memory size typically also have different SRAM and EEPROM.
