In STM32CubeMX clock schematic and in the clock schematic of the reference manual CK_PWR is mentioned. It is never explained what it does and what it is for.

I'd like to know what it is for and how it affects current consumption (since it is before the AHB prescaler).

Hi @Community member​ ,

The CK_PWR is an internal signal must be removed in the next update of the references Manuals and of the STM32CubeMx clock schematic.

Also, I recommended the AN4445 “STM32L0xx ultra-low power features overview�? to optimize the power consumption.
