This section lists the relevant devices for this document. The following figures show the different family 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
- 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
