Introduction to the
PN512 transceiver IC support four different working mode:
Support the ISO/IEC 14443 a/MIFARE and get its FeliCa scheme of read/write mode
Support ISO/IEC 14443 b read/write mode
Support ISO/IEC 14443 a/MIFARE and get its FeliCa card working mode
NFCIP - 1 model
PN512 internal send instruments have ISO/IEC 14443 a/MIFARE read/write mode, antenna and transponder can drive, speaking, reading and writing, and without the need for additional active circuit; The read/write antenna design is used for ISO/IEC 14443 a/MIFARE card of communication. Receiver demodulation and decoding part can be stable and efficiently from the ISO/IEC 14443 type a/compatible MIFARE card and transponder signal. Digital part processing complete ISO/IEC 14443 a into frames and error detection (parity and CRC).
PN512 support MIFARE 1 k and MIFARE 4 k simulation products. PN512 support MIFARE higher transmission rate (up to 424 KB/s) two-way contactless communication.
PN512 transceiver IC has get its FeliCa, speaking, reading and writing mode, support to get its FeliCa communication solution. Receiver scheme, provide a stable and efficient demodulation and decoding circuit compatible get its FeliCa coded signal. Digital part processing get its FeliCa into frames and the error detection, such as the CRC. PN512 support get its FeliCa higher transmission rate (up to 424 KB/s) two-way contactless communication.
PN512 support ISO/IEC 14443 b read and write all the levels of communication, the premise is an additional element (such as generator, power supply, coil, etc.) has the correct deployment, assuming the standard protocol (such as ISO/IEC 14443-4 and/or ISO/IEC 14443 b tamper-proof) has been properly deployed.
In the card working mode, PN512 transceiver IC according to get its FeliCa or ISO/IEC 14443 a/MIFARE card interface scheme in response to read or write command. PN512 produce digital load modulation signal, used with external circuit back to the response signal, speaking, reading and writing. Only through S squared C interface used with security IC, can provide complete security card function.
In addition, the PN512 transceiver IC and mode of NFCIP NFCIP - 1-1 devices communicate directly. NFCIP - 1 model offers all kinds of communication mode and up to 424 KB/s transmission rate, conform to the Ecma NFCIP 340 and ISO/IEC 18092-1 standard. Digital part processing complete NFCIP - 1 into frames and error detection.
Integration of a variety of host controller interface:
8-bit parallel interface
Serial UART (similar to the RS232, voltage level depends on the welding plate supply voltage)
I squared C interface.
The boon wisdom pu IC buyers must have the appropriate third party patent license.
