2.2 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, the STM32F103xC, STM32F103xD and STM32F103xE are
referred to as high-density devices and the STM32F103xF and STM32F103xG are called
XL-density devices.
Low-density, high-density and XL-density devices are an extension of the STM32F103x8/B
medium-density devices, they are specified in the STM32F103x4/6, STM32F103xC/D/E and
STM32F103xF/G 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
2
S and
DAC. XL-density devices bring even more Flash and RAM memory, and extra features,
namely an MPU, a greater number of timers and a dual bank Flash structure while
remaining fully compatible with the other members of the family.
The STM32F103x4, STM32F103x6, STM32F103xC, STM32F103xD, STM32F103xE,
STM32F103xF and STM32F103xG 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.

1. For orderable part numbers that do not show the A internal code after the temperature range code (6 or 7), the reference
datasheet for electrical characteristics is that of the STM32F103x8/B medium-density devices.
2. 64 KB RAM for 256 KB Flash are available on devices delivered in CSP packages only.
3. Ports F and G are not available in devices delivered in 100-pin packages.
4. Ports F and G are not available in devices delivered in 100-pin packages.
