Description  
STM32F103x4, STM32F103x6  
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, and the STM32F103xC, STM32F103xD and STM32F103xE are  
referred to as high-density devices.  
Low- and high-density devices are an extension of the STM32F103x8/B 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  
2
additional peripherals like SDIO, FSMC, I S and DAC, while remaining fully compatible with  
the other members of the STM32F103xx family.  
The STM32F103x4, STM32F103x6, STM32F103xC, STM32F103xD and STM32F103xE  
are a drop-in replacement for STM32F103x8/B medium-density 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.
