NXP MFRC523 无接触读卡器参考设计
The MFRC523 is a highly integrated reader/writer for contactless communication at
13.56 MHz. The MFRC523 reader supports ISO/IEC 14443 A/MIFARE mode.
The MFRC523’s internal transmitter is able to drive a reader/writer antenna designed to
communicate with ISO/IEC 14443 A/MIFARE cards and transponders without additional
active circuitry. The receiver module provides a robust and efficient implementation for
demodulating and decoding signals from ISO/IEC 14443 A/MIFARE compatible cards and
transponders. The digital module manages the complete ISO/IEC 14443 A framing and
error detection (parity and CRC) functionality.
The MFRC523 supports MIFARE Mini, MIFARE 1K and MIFARE 4K (MIFARE Standard)
products. The MFRC523 supports contactless communication and uses MIFARE higher
transfer speeds up to 848 kBd in both directions.
The MFRC523 supports all layers of the ISO/IEC 14443 B reader/writer communication
protocol provided that, external components such as oscillator, power supply and coil, and
..
