RE: how to measure the power off current on NRF54L15

Can you help me find Power_off sample for this DK? I was looking at samples but didn't find this one particularly.

As I understand it if you want sub 1µA you need to disable RAM retention in system OFF mode, which should not be a problem since the chip will reset upon wakeup.

From my understanding you also need to disable RAM retention Please try to add the following 4 lines directly before calling system OFF:

NRF_MEMCONF->POWER[0].RET = 0;
NRF_MEMCONF->POWER[1].RET = 0;
NRF_MEMCONF->POWER[0].RET2 = 0;
NRF_MEMCONF->POWER[1].RET2 = 0;
