1 tinyAVR 1-Series Overview

Figure 1-1 shows the tinyAVR 1-series, laying out pin count variants and memory sizes:

  • Vertical migration can be done upwards without code modification, since these devices are pin compatible and provide the same or even 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 also the available features.

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