The figure below shows the tinyAVR 0-series, 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.
