Hello,

The difference between P & Q:

  • "P" means : external SMPS
  • "Q" means : internal SMPS step-down converter

Hi ,

There is also pacakge

"stm32l552_562_ufbga132" means: whether can be used as both the external and internal SMPS? Correct me if i'm wrong.

Hope for the "STM32L552" series the package "stm32l552_562_ufbga132_q" can be used, since the feature of this series is SMPS step-down converter mode.

Kindly please help to know.

Thanks,

Suba.

Hi,

UFBGA132 package is for STM32L552xx and internal SMPS (STM32L552xxxxQ).

There is no UFBGA132 External SMPS, this will be removed from the document.
