1 Relevant Devices

This section lists devices that are applicable to this document. The following figure shows the different family devices, pin count variants and flash memory sizes:

  • Vertical migration upwards is possible without code modification, as these devices are pin-compatible and offer equivalent or enhanced features
  • Horizontal migration to the left reduces the pin count and potentially the number of available features
  • Devices with different flash memory sizes typically also have different SRAM and EEPROM
