MFRC522：标准3V MIFARE读卡器解决方案

MFRC522是一款高度集成的读/写IC，可实现13.56 MHz时的非接触式通信。MFRC522读卡器支持ISO/IEC 14443 A/MIFARE模式。

MFRC522的内部发射器无需额外的有源电路即能驱动专为与ISO/IEC 14443 A/MIFARE卡和发射应答器通信而设计的读/写天线。接收器模块提供一个强大且高效的解调和解码电路，可用于ISO/IEC 14443A/MIFARE兼容卡和发射应答器信号。数字模块管理完整的ISO/IEC 14443 A成帧与错误检测（奇偶校验和CRC）功能。

MFRC522支持MF1xxS20、MF1xxS70和MF1xxS50产品。MFRC522支持使用最快848 kBd的MIFARE更高传送速度进行双向非接触式通信。

提供以下主机接口：

MFRC522提供两种版本：

MFRC522 2.0 版完全兼容1.0版本，并提供除下列功能和改进：
