Listener for the ST25R3916 poller

[DRyu.2]

Our application is not related to payment but more around NFC charging and tagging, we'll be using the X-NUCLEO-NFC06A1 (+ NUCLEO-L476RG) combination for the poller.

Regarding the listener, we saw that the ST25DVxxKC lineup would be compatible. I'm not too familiar, but what would be the main differences between the ST25DV04KC, ST25DV16KC, or ST25DV64KC models? It seems the EEPROM is the main differentiator, but what implications does the capacity of this memory have on NFC performance? Are there cost/benefit tradeoffs?

Also regarding a development board for the listener (for example the ST25DV64KC), what would be the appropriate choice? I see that there are three options: STEVAL-SMARTAG2, ST25DV64KC-DISCO, and ANT7-T-25DV64KC. Could you briefly explain what the differences would be and what the best choice for NFC charging/tagging development would be?

Also, would the poller (ST25R3916) and listener (ST25DVxxKC) combination be WLC 2.0 compliant?

Hello,

Difference between ST25DV04KC, ST25DV16KC and ST25DV64KC is the size of the EEPROM. All other functions are identical. Memory capacity has no impact on NFC performance, it is only a matter of knowing how much memory your application will require. Off course, lower memory sizes are cheaper.

Regarding development board, there is also the X-NUCLEO-NFC07A1 board (https://www.st.com/en/ecosystems/x-nucleo-nfc07a1.html). It is a shield that plugs directly on top of a STM32 nucleo board. This board is aim for development, that why I recommend you to go with this one. Other boards are more demonstrators/examples.

As for WLC 2.0 implementation, this is a more complex. I recommend you to contact your local ST sales office for a dedicated assistance on this question.

Best regards.

Hello,

Thanks for the response.

I see that the X-NUCLEO-NFC07A1 board supports the ST25DV64KC. So it would be possible to use it as the listener and test it with a poller X-NUCLEO-NFC06A1, correct? So in essence we will be testing the ST25DV64KC to the ST25R3916.

Would both the NFC06A1 and NFC07A1 shields be compatible with the NUCLEO-L476RG

?

Regarding WLC 2.0 implementation, it sounds like it's not as simple as getting a library and then plug-and-play. Would this be something where we would need contracting service from ST? Or in what way would the local ST sales office be able to provide support?

Thank you.
