2.2

Full compatibility throughout the family

The STM32F105xx and STM32F107xx constitute the connectivity line family whose

members are fully pin-to-pin, software and feature compatible.

The STM32F105xx and STM32F107xx are a drop-in replacement for the low-density

(STM32F103x4/6), medium-density (STM32F103x8/B) and high-density

(STM32F103xC/D/E) performance line devices, allowing the user to try different memory

densities and peripherals providing a greater degree of freedom during the development

cycle.
