Brief introduction
The PN512 transceiver IC supports 4 different operating modes:
-
支持ISO/IEC 14443A/MIFARE和FeliCa方案的读写模式
-
支持ISO/IEC 14443B的读写模式
-
支持ISO/IEC 14443A/MIFARE和FeliCa方案的卡片工作模式
-
NFCIP-1模式
The PN512 internal transmitter has ISO/IEC 14443A/MIFARE read/write mode to drive read/write antennas and transponders without the need for additional active circuitry; This read/write antenna is designed for communication with ISO/IEC 14443A/MIFARE cards. The receiver section reliably and efficiently demodulates and decodes signals from ISO/IEC 14443A/MIFARE compliant cards and transponders. The digital part handles full ISO/IEC 14443A framing and error detection (parity and CRC).
The PN512 supports MIFARE 1K or MIFARE 4K emulation products. The PN512 supports two-way contactless communication using MIFARE's high transmission rate (up to 424 kb/s).
The PN512 transceiver IC has a FeliCa read/write mode and supports FeliCa communication solutions. The receiver provides a stable and efficient demodulation and decoding circuit scheme and is compatible with FeliCa encoded signals. The digital part handles FeliCa framing and error detection, such as CRC. The PN512 supports two-way contactless communication using FeliCa's high transmission rate (up to 424 kb/s).
The PN512 supports all levels of the ISO/IEC 14443B read/write communication scheme, provided that additional components (e.g., oscillators, power supplies, coils, etc.) are properly deployed and standard protocols (e.g., ISO/IEC 14443-4 and/or ISO/IEC 14443B anti-interference) are properly deployed.
In card operation mode, the PN512 transceiver IC can respond to read and write commands according to FeliCa or ISO/IEC 14443A/MIFARE card interface schemes. The PN512 generates a digital load modulation signal that works with an external circuit to send the response signal back to the reader. Only when used with a security IC through the S²C interface can the complete security card function be provided.
In addition, the PN512 transceiver IC can communicate directly with NFCIP-1 devices in NFCIP-1 mode. NFCIP-1 mode offers a variety of communication modes and transfer rates of up to 424 kb/s in accordance with Ecma 340 and ISO/IEC 18092 NFCIP-1 standards. The digital part handles full NFCIP-1 framing and error detection.
