Full compatibility throughout the family

The STM32F101xx is a complete family whose members are fully pin-to-pin, software and

feature compatible.In the reference manual, the STM32F101x4 and STM32F101x6 are

identified as low-density devices, the STM32F101x8 and STM32F101xB are referred to as

medium-density devices, the STM32F101xC, STM32F101xD and STM32F101xE are

referred to as high-density devices, and the STM32F101xF and STM32F101xG are referred

to as XL-density devices.

Low-, high-density and XL-density devices are an extension of the STM32F101x8/B

medium-density devices, they are specified in the STM32F101x4/6, STM32F101xC/D/E

and STM32F101xF/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 densities, and

additional peripherals like FSMC and DAC. XL-density devices bring greater Flash and

RAM capacities, and more features, namely an MPU, a higher number of timers and a dual

bank Flash memory, while remaining fully compatible with the other members of the family.

The STM32F101x4, STM32F101x6, STM32F101xC, STM32F101xD, STM32F101xE,

STM32F101xF and STM32F101xG are a drop-in replacement for the STM32F101x8/B

devices, allowing the user to try different memory densities and providing a greater degree

of freedom during the development cycle.

Moreover, the STM32F101xx access line family is fully compatible with all existing

STM32F103xx performance line and STM32F102xx USB access line devices.
