Description

2.1

Full compatibility throughout the family

The STM32F405xx and STM32F407xx are part of the STM32F4 family. They are fully pin-

to-pin, software and feature compatible with the STM32F2xx devices, allowing the user to

try different memory densities, peripherals, and performances (FPU, higher frequency) for a

greater degree of freedom during the development cycle.

The STM32F405xx and STM32F407xx devices maintain a close compatibility with the

whole STM32F10xxx family. All functional pins are pin-to-pin compatible. The

STM32F405xx and STM32F407xx, 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 STM32F40x

family remains simple as only a few pins are impacted.

Figure 4, Figure 3, Figure 2, and Figure 1 give compatible board designs between the

STM32F40x, STM32F2xxx, and STM32F10xxx families.
