Figure 1 shows the tinyAVRâ„¢ 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.

Overview
Devices with different Flash memory size typically also have different
SRAM and EEPROM.
The name of a device of the series contains information as depicted
