Compatible MCU among stm32f4 series

[EHa.1]

Hi, everyone. I am Emily.

I would like to know the MCU which is compatible to 'stm32f446RET'.

Also I wanna double-check the possiblity of compatible usage between 'stm32f407VET'​ and 'stm32f417VET'.

Please help me:crying_face:​

Hi @EHa.1​ ,

If I well understand your request, you're searching for a STM32 MCU that best matches your STM32f446RET.

So what I can propose here is to download and install ST-MCU-FINDER.

This application integrates the Cross Selector feature which allows you to find products of the STM32 portfolio that best replace the MCU or MPU you are currently using.

Hope this facilitates your search.

Thanks a lot :D

I can find that 'stm32f407VET'​ and 'stm32f417VET are compatible each other.

And I have one more question...

Can I use a same FW code with not different but compatible MCUs?

I guess I can use the same FW code, but I am not sure...

Kindly your help, thank you.

Hello @EHa.1​ 

STM32Cube includes a comprehensive embedded software platform, delivered per Series (such as STM32CubeF4 for STM32F4 Series).

Thus, for two compatible MCUs from the same family (STM32F407VET​ and STM32F417VET), you'll use the same STM32CubeF4 firmware. 

Otherwise, you can find also compatible MCUs from different series:

In this case you can't use the same FW.

I hope I've answered your question.

Khouloud.
