STM32WBA55CGU6 - CubeIDE footprint - UFQFPN48 vs. UFQFPN48 SMPS

Hello there,

 

I ran into an issue with my STM32WBA55CGU6 chip. I designed my board with schmematics from Mouser: 511-STM32WBA55CGU6 with the UFQFPN48 pinout. When setting up my chip in CubeIDE I also chose the STM32WBA55CGU6 version. But when comparing the pinout of the chip the SMPS version of the UFQFPN48 footprint is displayed.

Is this an issue I can solve by selecting the correct footprint in CubeIDE or is it, that CubeIDE is wrong at that point?

 

The UFQFPN48 version should have PB12 on Pin1 and not VSSSMPS as shown in the image.

 

Thanks in advance,

Tim

Seems to me that CubeIDE is right, the STM32WBA55CGU6 is the SMPS version, if You want the LDO Version You need the STM32WBA54CGU6.
