Power conumption between "NRF_GPIOTE_LATENCY_LOWLATENCY" & "NRF_GPIOTE_LATENCY_LOWPOWER" in NRF5340 dk

David Duan

HI Devzon 

currently my customer has some question about the power consumption difference between "LOWLATENCY" & "LOWPOWER" on NRF5340 GPIOTE

we useing PPK2 to testing the power consumption when GPIOTE setting as lowlatency & lowpower, but we don't see too many difference on power consuption between these two setting

below it is our testing project:

GPIOE_TST_v2.7z

and i check the datasheet for NRF5340, there is no Electrical specification for GPIOTE config in lowlatency & lowpower.

do we have some power consumption data for GPOTE lowlatency & lowpower

    Hi,

    The sample you uploaded had UART enabled which lead to a high floor current. Try to add CONFIG_SERIAL=n to your prj.conf file.

    This is what I got with the low latency mode:

    And same with the low power mode:

    The network core was programmed to stay in System ON mode.

    Best regards,

    Vidar
