The PN533 is a highly integrated transceiver module that enables contactless communication at 13.56 MHz based on the 80C51 microcontroller core. Support 6 different working modes:
-
ISO/IEC 14443A/MIFARE读/写模式
-
FeliCa读/写模式
-
ISO/IEC 14443B读/写模式
-
ISO/IEC 14443A/MIFARE卡MIFARE 1 KB或MIFARE 4 KB仿真模式
-
FeliCa卡仿真模式
-
ISO/IEC 18092、ECMA 340对等模式
The PN533 uses a demodulator and decoder to process signals from ISO/IEC 14443A/MIFARE compliant cards and transmit transponders. The PN533 performs full ISO/IEC 14443A frame and error detection (parity and CRC).
The PN533 supports MIFARE 1 KB or MIFARE 4 KB emulation products. The PN533 supports higher-speed MIFARE contactless communication with bidirectional transmission rates of up to 424 kbit/s.
The PN533 can demodulate and decode FeliCa-encoded signals. The PN532 is capable of FeliCa frame and error detection. The PN533 supports FeliCa's higher-speed contactless communication with bidirectional transmission rates of up to 424 kbit/s.
The PN533 supports Layer 2 and 3 of the ISO/IEC 14443 B read/write communication scheme, except for collision prevention. It must be adopted in the firmware as well as in the upper layers.
In card emulation mode, the PN533 is able to respond to read/write commands according to FeliCa or ISO/IEC 14443A/MIFARE card interface schemes. The PN533 generates a load modulation signal from its transmitter or from the LOADMOD pin that drives an external active circuit. Full security card functionality is only possible when combined with an encryption IC using the NFC-WI/S²C interface.
Compliant with ECMA 340 and ISO/IEC 18092 NFCIP-1 passive and active communication modes, the PN533 can communicate with another NFCIP-1 compliant device at a maximum transfer rate of 424 kbit/s. The PN533 performs full NFCIP-1 frame and error detection.
The PN533 transceiver can be connected to an external antenna for read/write or card/PICC mode without the need for any additional active components.
The PN533 supports the following host interfaces:
-
USB 2.0全速接口（总线供电或非总线供电）
-
高速UART (HSU)
The PN533 also has a main I²C interface to drive I²C peripherals (i.e., memory).
In addition, a power switch is included to supply power to the encryption IC.
