SMPS Pinout not available (STM32WBA)

le1 · ‎2025-10-27

Hello!

I'm trying to set up a program via STM32CubeMX. The MCU I'm trying to use is the STM32WBA65CIU6 with the SMPS Pinout.

source: datasheet page 72 (https://www.st.com/resource/en/datasheet/stm32wba62ci.pdf).

However this configuration seemingly isn't available in STM32CubeMX, only the SMPS_USB Version.

source: STM32CubeMX with STM32WBA65CIUx chosen as MCU.

There's only one MCU listed in the MCU/MPU selector. Just in case if there are supposed to be multiple.

source: STM32CubeMX with search-string STM32WBA65CIU6 in commercial part number.

Is there an option that I'm missing? Or will I have to address this manually in code?

Thank you in advance!

This has USB, so the correct pinout is chosen.

Perhaps you want STM32WBA63xxx?

Thanks for your quick reply! So that means that even though these MCUs share the same Package they don't necessarily share the same pinout. Instead that depends on the specific feature set that they employ? That's probably common knowledge, but knowledge that I didn't have. Good to know :D

I guess that answers it. Thank you!
