STM32F437xx
Description
2.1 Full
compatibility throughout the family
The STM32F437xx 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 STM32F437xx devices maintain a close compatibility with the whole STM32F10xx
family. All functional pins are pin-to-pin compatible. The STM32F437xx, 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 STM32F43x 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.
