STM32F20xxx Description

2.1 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 3 and Figure 1 provide compatible board designs between the STM32F20x and the

STM32F10xxx family.
