NTAG5 version with SUN / CMAC signature mapping?

[amal]

Does anyone know if any of the NTAG5 chip types support the SUN type counter based CMAC memory mapped signatures on NFC read similar to the NTAG424? We are looking for an NTAG5 Link type chip that support I2C bus comms protected by mutual authentication but also allows a simple cmac signed NFC read we can auth with just a browser no special app.

Hello @amal 

NTAG 5 Link does not have such a feature, you only select NTAG 424 DNA, but which is not I2C interface. Based on your needs, there is currently no better recommendation. Sorry, please understand.

Ok thank you. Does NTAG Link or Boost support any mapping features at all like UID and / or COUNTER into the user memory on NFC read?

Hello @amal 

Maybe pass-through mode is the feature that you want to know about, see the datasheet for details:

NTAG 5 link - NFC Forum-compliant I2C bridge (nxp.com.cn)
