Product data sheet
10.1 Automatic host controller interface type detection
10.2 SPI compatible interface
The PN512 supports direct interfacing of various host controllers as the 8-bit parallel, SPI,
I
host controller interface type automatically having performed a Power-On or Hard Reset.
The PN512 identifies the host controller interface by the means of the logic levels on the
control pins after the Reset Phase. This is done by a combination of fixed pin connections.
The following table shows the different configurations:

[2]
A serial peripheral interface (SPI compatible) is supported to enable high speed
communication to the host controller. In the communication with a host controller PN512
acts as a slave receiving data from the external host controller for register settings and to
send and receive data relevant for the communication on the RF interface.
