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.
