Hi @FAdar.1 ,
Could you please precise the exact part number you selected for STM32WB5?
Knowing the exact part number, you can refer to its datasheet and check its pinout in order to compare it with pins definition on DS11929.
Another possible option is to have a look to the application note AN5451 Migrating between STM32WB30/35/50/55 microcontrollers.
I believe that you will find there all what you need as description of compatibilities & differences between various STM32WB devices.
Hope my answer helped you, when your question is answered, please close this topic by choosing Select as Best.
