nRF52 as NFC reader

Is it possible to use the NFC functionality in the nRF52 series chip to read NFC tags?

  • Little bit more precise answer could be: there is no way how to drive the 13.56 MHz field from nRF52 chip so doing NFC reader does not make sense. On the bright side: there are cheap ICs which will do this job for you so you will only pay by small additional cost + space on PCB and power if you really want this.

  • Hi Bartek, I'm pure SW developer and my knowledge of HW design is limited so I cannot judge these items from layout/PCB real estate/BOM cost point of view. I'd expect that for reader this isn't such a problem because HF (13.56MHz) contactless (NFC if you want) is such specific discipline that you need real expert to produce at least so-so tuning and then you simply take his recommendation (because saving few cents on BOM or similar is not worth months of learning and discovering completely new vendor/component). At least this is what I've seen during my professional career in smart card business;)

    Cheers
