NXP MFRC530 ISO14443A无接触读卡方案

NXP公司的MFRC530支持ISO14443A通信方案所有层面的高度集成的13.56MHz无接触通信的读卡器IC,它采用杰出的调制和解调技术,内部的发送器能驱动接近100毫米距离的天线,接收器则能有效地实现对来自ISO14443A兼容的转发器信号进行解调,数据速率高达424k波特.本文介绍了MFRC530主要特性,方框图, 接收器电路框图, 定时器模块框图,以及与微处理器的连接框图和典型应用电路图.

The MF RC530 is member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz. This reader IC family utilises an outstanding modulation and demodulation concept completely integrated for all kinds of passive contactless communication methods and protocols at 13.56 MHz. The MF RC530 is pin- compatible to the MF RC500, the MF RC531, SL RC400 and CL RC632.

The MF RC530 supports all layers of the ISO14443A communication scheme.

The MF RC530 supports contactless communication using MIFARE® Higher Baudrates.

The internal transmitter part is able to drive an antenna designed for proximity operating distance (up to 100 mm) directly without additional active circuitry.

The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from ISO14443A compatible transponders.
