    Hello Roy,

    Thank you for your patience while I was out of office last week.

    The TCAN4551 must be connected to a MCU.  I don't know what the details are for the Automotive high performance NFC reader block are, but it needs to have a MCU with a SPI interface.  If this NFC reader does not have a MCU with a SPI interface, then you would need an additional MCU between the NFC reader block and the TCAN4551 on the left half of this diagram.

    Regards,
