STM32F401 and STM32U575 Pin compatibility QFN48 and LQFP48 package

[Nilav]

Hi All,

I wanted to move from STM32F401 to a ECC enabled MCU and came across the STM32U575/585 series. Is it possible to in place use the QFN48 package for stm32u575 in place of stm32f401?. The pinouts/ports/power pins all look to be the same. are there any red flags?

Please help with your expert advice!

Regards,
Nilav

Hello @Nilav 

To verify if they are compatible or not, you can use the STM32 CubeMX and follow those steps:

• Create a project using the MCU that you are currently working with.
• Select pinout->List Pinout- Compatible MCUs. 

Then you can find all MCUs compatible with yours.

Best regards.

Thanks @Issamos . This helps. Just as a note. The pinout for stm32u575 and stm32f401 look to be the same and I'm checking if it works in place for my use case.. I will keep you posted.
