nrf54L15 sleep current was 3uA using NCS\v2.8.0\zephyr\samples\boards\nordic\system_off

Hi,

I test my nrf54l15 module(disconnect every gpio with outside),the sleep current was 3uA,seens can't not achieve 0.6uA as the datasheet said.

The nrf54L15's markcode is QFAABB 2435AD.

I testing with the default setting of NCS\v2.8.0\zephyr\samples\boards\nordic\system_off sample.

  • 1.1µA is pretty good. Are you working on a custom board or an nRF54L15 DK? In your current consumption measurement it seems like the floor current is 0.7µA, but that there are some spikes rather often that seems to wake up the device, so is there something maybe waking the device up pretty often here? A GPIO being triggered or similar?

    Best regards,

    Simon
