11.5.1 Serial data switch for driver
11.5 Serial data switch
11.6 S
Two main blocks are implemented in the PN512. A digital circuitry, comprising state
machines, coder and decoder logic and an analog circuitry with the modulator and
antenna drivers, receiver and amplification circuitry. The interface between these two
blocks can be configured in the way, that the interfacing signals may be routed to the pins
SIGIN and SIGOUT. SIGIN is capable of processing digital NFC signals on transfer
speeds above 424 kbit. The SIGOUT pin can provide a digital signal that can be used with
an additional external circuit to generate transfer speeds above 424 kbit (including 106,
212 and 424 kbit). Furthermore SIGOUT and SIGIN can be used to enable the S
interface in the card SAM mode to emulate a card functionality with the PN512 and a
secure IC. A secure IC can be the SmartMX smart card controller IC.
The serial signal switch is controlled by the register TxSelReg and RxSelReg.
The following figure shows the serial data switch for pins TX1 and TX2.
Pin SIGIN is in general only used for SAM communication. If TxMix is set to logic 1, the
driver pins are simultaneously controlled by SIGIN and the internal coder.
The S
as a contactless smart card IC via the PN512. The interfacing signals can be routed to the
pins SIGIN and SIGOUT. SIGIN can receive either a digital FeliCa or digitized
ISO/IEC 14443A signal sent by the secure IC. The SIGOUT pin can provide a digital
signal and a clock to communicate to the secure IC. A secure IC can be the smart card IC
provided by NXP Semiconductors.
The PN512 has an extra supply pin (SVDD and PVSS as Ground line) for the SIGIN and
SIGOUT pads.
