I have been struggling with getting low current consumption in my STM32L4 designs. To try to get a benchmark I compiled the reference example in CubeMX repository v 1.13.0 (path STM32Cube\Repository\STM32Cube_FW_L4_V1.13.0\Projects\NUCLEO-L432KC\Examples\PWR\PWR_STOP2) and deployed it on the Nucleo-L432KC board rev C (just as the readme.txt mentioned).
But the STOP2 current consumption is 10mA and not close to 1 microamp expected!! I have not changed a bit in the code in the repository.
Do anyone have a clue what is going on? I am measuring the current through the J1 IDD connector.
The lowest I have reached with a STM42L4 in my own designs in stop mode was 160 microamps which is still quite high compared to what to expect.
