概述
ST25R3916/7是高性能NFC通用器件，支持NFC启动器、NFC目标器、NFC读写器和NFC卡仿真模式。
该NFC IC完全符合EMVCo 3.0模拟和数字标准，针对POS终端应用进行了优化，即使在嘈杂的LCD显示器周围的天线恶劣条件下，也能实现最快的EMVCo 3.0认证周期。
这两款设备都包括一个先进的模拟前端(AFE)和一个高度集成的数据帧系统，用于ISO 18092被动和主动启动器，ISO 18092被动和主动目标，NFC-A/B (ISO 14443A/B)读取器，包括更高的比特率，NFC-F (FeliCa™)读取器，NFC-V (ISO 15693)读取器，高达53 kbps，以及NFC-A/ NFC-F卡仿真。
AFE和分帧系统的特殊流和透明模式可用于在读写器或卡仿真模式下实现其他自定义协议。
ST25R3916/7具有高射频输出功率，可高效直接驱动天线。
ST25R3916/7包括其他功能，使其在低功耗应用中无与伦比。
ST25R3916/7设计用于宽电源范围(-40°C至+105°C范围内的2.6至5.5 V， -20°C至+105°C范围内的2.4至5.5 V)和宽外设IO电压范围(1.65至5.5 V)。
由于这种高RF输出功率，低功率模式和宽供电范围的组合，这些器件非常适合基础设施NFC应用。
