STM32L4R5ZI Stop 2 Mode Current Consumption

Hi to all,

I recently started to work on NUCLEO-L4R5ZI-P evaluation board; for my first tests I decided to test the current consumption using the JP5 jumper. I put an external 8MHz oscillator on X3 and using a pre-defined test project I tried to go into stop 2 mode; checking my current consumption with what datasheet shows I note an huge difference. Disabling SRAM3 and using the RTC to exit from low power mode, I measure on JP5 about ~75uA in stop 2 mode while in the datasheet this current should be about ~3uA. Please could anyone suggest me what I missing ?

Regards

Hello,

If you are using the X3 oscillator, you must follow this configuration:
