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, 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.
