9.1 CONTACT LESS MODULE
The PN532 includes a highly integrated transmission/reception module for contactless
communication at 13.56 MHz. This transmission/reception contact less (CL) module
utilises an outstanding modulation and demodulation concept completely integrated for
different kinds of contactless communication methods and protocols at 13.56 MHz.
The CL module support 4 different operating modes
Enabled in reader / writer mode for ISO 14443A / MIFARE
part is able to drive a reader / writer antenna designed to communicate with ISO 14443A /
MIFARE
receiver part provides a robust and efficient implementation of a demodulation and
decoding circuitry for signals from ISO 14443A / MIFARE
transponders. The CL module handles the complete ISO 14443A framing and error
detection (Parity & CRC).The CL module supports MIFARE
Standard) products. The CL module supports contactless communication using MIFARE
Higher transfer speeds up to 424 kbit/s in both directions.
Enabled in reader / writer mode for FeliCa™, the CL module supports the FeliCa™
communication scheme. The CL module receiver part provides a robust and efficient
implementation of the demodulation and decoding circuitry for FeliCa™ coded signals.
The CL module digital part handles the FeliCa™ framing and error detection like CRC.
The CL module supports contactless communication using FeliCa™ Higher transfer
speeds up to 424 kbit/s in both directions.
The CL module supports all layers of the ISO/IEC 14443 B reader / writer communication
scheme, given correct implementation of additional components, like oscillator, power
supply, coil etc. and provided that standardised protocols, e.g. like ISO/IEC 14443-4
and/or ISO/IEC 14443 B anticollision are correctly implemented. The use of this Philips IC
according to ISO/IEC 14443 B might infringe third party patent rights. A purchaser of this
Philips IC has to take care for appropriate third party patent licenses.
In card operation mode, the CL module is able to answer to a reader / writer command
either according to the FeliCa™ or ISO 14443A / MIFARE
CL module generates the digital load modulated signals and in addition with an external
circuit the answer can be sent back to the reader / writer. A complete card functionality is
only possible in combination with a secure core IC using the S2C interface.
Additionally, the CL module offers the possibility to communicate directly to an NFCIP-1
device in the NFCIP-1 mode. The NFCIP-1 mode offers different communication modes
and transfer speeds up to 424kbit/s according to the Ecma 340 NFCIP-1 Standard. The
CL module digital part handles the complete NFCIP-1 framing and error detection.
