2.1

Full compatibility throughout the family

The STM32F427xx and STM32F429xx devices 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 STM32F427xx and STM32F429xx devices maintain a close compatibility with the

whole STM32F10xx family. All functional pins are pin-to-pin compatible. The STM32F427xx

and STM32F429xx, however, are not drop-in replacements for the STM32F10xx devices:

the two families do not have the same power scheme, and so their power pins are different.

Nonetheless, the transition from the STM32F10xx to the STM32F42x family remains simple

as only a few pins are impacted.

Figure 1, Figure 2, and Figure 3, give compatible board designs between the STM32F4xx,

STM32F2xx, and STM32F10xx families.
