PN532 is a highly integrated transceiver module, the kernel based on 80 c51 micro controller, which can realize the contactless communication when the 13.56 MHz. Support the work of six different modes:
ISO/IEC 14443 a/MIFARE read/write mode
Get its FeliCa read/write mode
ISO/IEC 14443 b read/write mode
ISO/IEC 14443 a/MIFARE card MIFARE Classic 1 k or 4 k MIFARE Classic card simulation model
Get its FeliCa card simulation model
ISO/IEC 18092, ECMA 340 peer mode
PN532 USES the demodulator and decoder, processing from the ISO/IEC 14443 a/compatible MIFARE card and launch the transponder signal. PN532 able to complete the ISO/IEC 14443 a frame and error detection (parity and CRC).
PN532 support MIFARE Classic 1 k or 4 k MIFARE Classic card simulation model. PN532 support two-way transmission rate is as high as 424 kbit/s MIFARE more contactless communication at a high speed.
PN532 to get its FeliCa coding signal demodulation and decoding. PN532 to get its FeliCa frame and error detection. PN532 support two-way transmission rate is as high as 424 kbit/s get its FeliCa more contactless communication at a high speed.
PN532 support ISO/IEC 14443 B read/write device communication scheme of layer 2 and 3, except for conflict prevention. Must adopt in the firmware and the upper.
In the simulation model, the PN532 can according to get its FeliCa or ISO/IEC 14443 a/MIFARE card interface scheme response to read/write command. PN532 from its sender or generated from the LOADMOD pin drive external active circuit load modulation signal. Use only with NFC - WI/S squared C interface encryption IC when combined, can achieve the function of complete security card.
Conform to the ECMA NFCIP 340 and ISO/IEC 18092-1 passive and active communication mode, PN532 to maximum transmission rate of 424 kbit/s and the other in conformity with the specification NFCIP - 1 devices to communicate. PN532 to complete NFCIP 1 frame and error detection.
PN532 transceiver can connect the external antenna is used to read/write or card/usm model, without any extra active components.
PN532 supports the following host interface:
I squared C
High speed UART (HSU)
Embedded low dropout voltage regulator allows for the device connected directly to the battery. In addition, with the power switch to the encryption IC power supply.
