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：
串行外设接口(SPI)
串行UART（类似RS232，电压电平取决于针脚电压供应）
I?C总线接口
版本1.0和2.0之间的差异
MFRC522提供两种版本：
MFRC52201HN1，以下简称1.0版
MFRC52202HN1，以下简称2.0版
MFRC522 2.0 版完全兼容1.0版本，并提供除下列功能和改进：
读卡器IC在恶劣条件下具有更高的稳定性
额外的定时器预分频器
RX Multiple设置为1时经过纠正的CRC处理
高度集成模拟电路进行解调和解码响应
缓冲输出驱动器，可使用最少外部组件连接天线
支持ISO/IEC 14443 A/MIFARE标准
读/写模式下的典型工作距离长达50 mm，具体取决于天线尺寸和调谐情况
读/写模式下支持MF1xxS20、MF1xxS70和MF1xxS50加密
支持ISO/IEC 14443 A较高通信传输速率（最高848 kBd）
支持MFIN/MFOUT
附加内部电源通过MFIN/MFOUT与智能卡IC连接
支持的主机接口
最快10 Mbit/s的SPI
快速模式下最高400 kBd，高速模式下最高3400 kBd的I?C总线接口
最高1228.8 kBd的RS232串行UART，其电压电平取决于针脚电压源
FIFO缓冲器可处理64字节发送和接收
灵活的中断模式
通过低功耗功能实现的硬复位
软件关断模式
可编程定时器
