Low-density
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.
