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.
