nrf5340 sleep currrent consumption

[Lavanya_Manohar]

In our custom board nrf5340-nrf7002, tried system_off(C:\ncs\v2.6.1\zephyr\samples\board\nrf )sample to check power consumption. 

But it measures 0.60mA

Is there any config need to address? please provide debug steps

Hello,

My colleague Priyanka is on leave now. It's holiday season here in Norway. Sorry for the late reply.

I suspect that GPIOTE IN is used for interrupts on your setup, then this will cause higher sleep current. Could you please check this?

Hi, 
Thank you for your response.

Yes, In our application we using 5 GPIO interrupt, Where 4 pin are PULL UP and 1 pin is pull down in hardware side.
In software wise, we using port rather than GPIOTE to save current. 

Here I share the software configuration of the pins in overaly FYR Please reviwe provide your feedback.

&gpio0 {

    status = "okay";

    /* Use PORT event rather than GPIOTE IN event, to save power */

    sense-edge-mask = <0xffffffff>;

};

&gpio1 {

    status = "okay";

    /* Use PORT event rather than GPIOTE IN event, to save power */

    sense-edge-mask = <0xffffffff>;

};
