I had using sample code "low power sleep mode", the current measure result is over datasheet spec, how to do can get datasheet value?

The measurement result is around 1mA, the datasheet show 60uA.

Hardware paltform: NUCLEO-G071RB

Software version: 1.3.0

Hello Felix,

To reach requested consumption you have to change clock source as stated in mentioned table 27 (in DataSheet), the HCLK should use fHSE bypass or fLSE bypass.

HSI itself has consumption of 155 uA see table Table 41. HSI16 oscillator characteristics in DataSheet.

SB17 it should be removed.
