PN532/C1
NFC controller
Enabled in card mode the PN532 transmission module is able to answer to a reader/writer
command either acoording to FeliCa™ or ISO14443 A / MIFARE
®
card interface mode.
The PN532 generates the digital load-modulated signals and in addition with an external
circuit the answers can be send back to the reader/writer. A complete card functionality is
only possible in combination with a secure memory IC.
Additionally, the PN532 transmission module offers the possibility to communicate directly
to a second NFCIP-1 device in the NFCIP-1 mode. The NFCIP-1 mode offers different
communication transfer speeds up to 424
kbit/s according to the ECMA 340 NFCIP-1
Standard. The digital part handles the complete NFCIP-1 framing and error detection.
Transfer speeds on the RF interface above 424 kbit/s are supported by the digital part of
the PN532 module. The modulation to transmit and the demodulation to receive data at
transfer speeds has than to be done by an external circuit.
To make information exchange to the host systems several interfaces are implemented:
• SPI interface
• I
2
C interface
• Serial UART (similar to RS232 with 0 and PVDD voltage levels)
The PN532 embeds a low dropout voltage regulator allowing the device to be connected
directly to a battery as well as a medium power switch to supply and control the power of
the companion secure chip.
