Full compatibility throughout the family

The STM32F103xC/D/E 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, I2S and DAC while

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.

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. Ports F and G are not available in devices delivered in 100-pin packages.
