1 Relevant Devices

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
