产品概述
描述
ST25R300是一款高性能NFC通用器件，可支持NFC发起设备、NFC接收设备、NFC读卡器以及NFC卡模拟模式。该器件设计符合EMVCo® PCD 3.2a模拟和数字标准，专门针对要求严苛的POS终端应用进行了优化。即使在嘈杂的LCD显示屏后安装天线，该器件也能在极具挑战性的条件下快速完成EMVCo®认证周期。
该器件集成了高级模拟前端 (AFE) 和高度集成的数据成帧系统，支持NFC‑A/B (ISO14443A/B) 读卡器（包括更高比特率）、NFC-F (FeliCa™)、NFC-V (ISO15693)，高达212 kbps的传输速率，以及NFC-A/NFC-F卡模拟。AFE和数据成帧系统的特殊低电平模式可在读卡器或卡模拟操作中实现其他自定义协议。
该器件具备高射频 (RF) 功率和动态功率输出，可直接高效驱动天线。即使门禁控制和EMVCo®读卡器的天线尺寸较小，该器件也能实现较大的交互距离。该器件通过测量I和Q信道（代表天线信号的实部和虚部），提供长距离、低功耗的卡片检测功能。这种方法能最大限度地降低功耗。ST25R300设计支持宽电源电压范围（2.7 V至6.0 V）、宽环境温度范围（-40 °C至+105 °C）以及宽外设I/O电压范围（1.65 V至5.5 V）。凭借高射频输出功率、低功耗模式以及宽电压范围，ST25R300成为所有NFC应用的理想之选。
