2 tinyAVR® 0-series Overview

The following figure shows the tinyAVR 0-series devices, laying out pin count variants and memory sizes:

  • Vertical migration upwards is possible without code modification, as these devices are pin-compatible and provide the same or more features. Downward migration may require code modification due to fewer available instances of some peripherals.
  • Horizontal migration to the left reduces the pin count and, therefore, the available features

Devices with different Flash memory sizes typically also have different SRAM and EEPROM.
