nRF52 current consumption during NFC wake on field

[rugarcia]

I want to confirm how much current is being drawn from the battery while the nRF52 is in it's absolute lowest power state and waiting for an NFC field to wake it up. From the datasheet I came up with the following. Is this correct?

The wake on field does require power. From the version 0.62 data sheet it looks like it needs ~500nA (400nA – SYS OFF, no ram retention + 100nA NFC current in SENSE STATE).

Thanks, Rudy

Hi,

Yes you are correct, however it is hard to measure on this right now due to the erratas with the NFC and the current chip I have available. I will come back to you when I figure out how to circumvent these issues.

Best regards,

Hi Oyvind, Can you please help me find some help on How to put the device nRF52 into NFC sense state Low power mode.
