Full compatibility throughout the family
The STM32F103xx is a complete family whose members are fully pin-to-pin, software and
feature compatible. In the reference manual, the STM32F103x4 and STM32F103x6 are
identified as low-density devices, the STM32F103x8 and STM32F103xB are referred to as
medium-density devices and the STM32F103xC, STM32F103xD and STM32F103xE are
referred to as high-density devices.
Low-density and high-density devices are an extension of the STM32F103x8/B medium-
density devices, they are specified in the STM32F103x4/6 and STM32F103xC/D/E
datasheets, respectively. Low-density devices feature lower Flash memory and RAM
capacities, less timers and peripherals. High-density devices have higher Flash memory
and RAM capacities, and additional peripherals like SDIO, FSMC, I
remaining fully compatible with the other members of the family.
The STM32F103x4, STM32F103x6, STM32F103xC, STM32F103xD and STM32F103xE
are a drop-in replacement for the STM32F103x8/B devices, allowing the user to try different
memory densities and providing a greater degree of freedom during the development cycle.
Moreover, the STM32F103xx performance line family is fully compatible with all existing
STM32F101xx access line and STM32F102xx USB access line devices.
