Si522A，13.56MHz非接触式读写器芯片--Si522A
Si522A是一个高度集成的，工作在13.56MHz的非接触式读写器芯片，阅读器支持ISO/IEC14443A/MIFARE，支持自动载波侦测功能（ACD）。
无需外围其他电路，Si522A的内部发送器可驱动读写器天线与ISO/IEC14443A/MIFARE卡和应答机通信。接收器模块提供一个强大而可靠的电路，用以解调译码ISO/IEC14443A/MIFARE兼容卡及应答机信号。数字模块处理完整的ISO/IEC14443A帧和错误检测功能(奇偶和CRC)。
ACD模式下，芯片大部分时间处于休眠状态，由3KRC定时唤醒，以低功耗侦13.56MHz的射频场和射频卡，检测到场或卡自动产生中断唤醒MCU。侦测场和卡的功能可以单独使能。在典型的500ms轮询周期下，电流约为2.9uA。整个ACD过程不需要MCU干预。
芯片实现了多种主机接口：
SPI接口
串行UART（类似RS232，电平取决于提供的管脚电压）
I2C接口
典型应用案例：
智能支付系统
智能电子锁系统
