Full compatibility throughout the family

The STM32F205xx and STM32F207xx constitute the STM32F20x family, whose members are fully pin-to-pin, software and feature compatible, allowing the user to try different memory densities and peripherals for a greater degree of freedom during the development cycle.

The STM32F205xx and STM32F207xx devices maintain a close compatibility with the whole STM32F10xxx family. All functional pins are pin-to-pin compatible. The STM32F205xx and STM32F207xx, however, are not drop-in replacements for the STM32F10xxx devices: the two families do not have the same power scheme, and so their power pins are different. Nonetheless, transition from the STM32F10xxx to the STM32F20x family remains simple as only a few pins are impacted.

Figure 1, Figure 2 and Figure 3 provide compatible board designs between the STM32F20x and the STM32F10xxx family.
