STM32WB15CC too much current consumption in stop1 mode.

[JGuir.1]

Hello,

I can't get a current lower than 108µA in stop1 mode. It's expected 3µA in the datasheet.

I set all pin in analog input mode, disable the debug in low power mode.

I try with the NUCLEO Board as explain in the article number n°2190.

I also removed all JP2 jumpers to decrease the current consumption of the shift level.

Has anyone always succed to get 3µA in stop1 mode with this MCU.

Thanks,

CPU2 was not in shutdown mode !

Now with CPU2 in shutdown mode (LL_C2_PWR_SetPowerMode(LL_PWR_MODE_SHUTDOWN);) current consumption is 3µA for CPU1 stop1 mode.

Sorry
