PN7150 writing to multiple tags

[__invited__hari]

Hi,

We are using NXP PN7150 RFID Reader IC and SL2S2002 RFID TAG ICs in our project.

The problem we are facing is, that data is written to multiple tags that are within that Reader vicinity. Do we know how to restrict those writes to a specified Tag, please? A detailed CMD, RSP, NTF handshake sequence to address this issue is highly appreciable.

Thanks,

Hari

Hello, my name is Fabian, I've been assigned to support your case.

Thank you for using our products.

According to UM10936 in section 6.4.4, PN7150 is able to resolve the collision of multiple ISO15693 and, it is limited to 2 devices. As it is indicated in section 4.2.5, the support is partial. But, please notice that this is only for the IC version C11006.

The used command for selecting each device is by using RF_DISCOVER_SELECT_CMD

I hope this information may have been useful.

Hello Fabian,

Thank you for the response. I will try that command implemented and let you know if I need any further assistance.

Thanks,
