PN7160 polling power consumption

[maibi]

Hi, I have ported NFC example on my board with OM27160A1HN and everything works fine. However, to apply this in real-world application, I need to reduce power consumption. I used LPCD with the MFRC630 series, but it doesn't seem to reduce power consumption to the extent I need. How much can I reduce the power consumption while keeping the polling on? Can you please provide me with information on the actual specs and how to use it?

Hi Maibi:

I would suggest you refer to AN 12990.--PN7160 low power configuration.  you can see the current consumption of discovery mode.
