Dear Team,

I am using STM32WBA5MMG in my project. The datasheet does not contain pin description and their alternate functions.

I also checked STM32WBA5xxx datasheet (DS14127). It does not contain any pin description and alternate functions of STM32WBA5MMG.

For finding the pin details of , may I know where I need to check in the datasheet.

According to the module datasheet:

mALLEm_0-1768401633641.png

And according to the MCU datasheet WBA55UG means:

mALLEm_1-1768401714875.png

So yes it's a UFBGA59 package with 1MB of Flash:

Hello,

From the DS14127 link: https://www.st.com/resource/en/datasheet/stm32wba52ce.pdf

I can see the pin description (Table 24):

What document link you are referring to?

PS: xxSMPS pins are supply pins and not GPIOs.

Hello,

Thank you very much.

In that document which one corresponds to STM32WBA5MMG. I am using the STM32WBA5MMG Module. This is an LGA package.

The datasheet is for the microcontroller but STM32WBA5MMG is a module: 

STM32WBA5MMG datasheet: https://www.st.com/resource/ja/datasheet/stm32wba5mmg.pdf

This is the module pinout, normally each pin has the same alternate functions as described in the MCU datasheet.
