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
