产品概述

描述

ST25R3918是一款多功能NFC收发器，支持NFC读卡器模式、点对点模式、以及NFC卡模拟模式。

该IC针对物联网和其他需要优异模拟性能的消费者或工业应用进行了优化。

ST25R3918也经过优化，采用降噪接收技术，即使在嘈杂且恶劣的环境下也能以较低的输出功率实现高读取范围。

该IC提供高级模拟前端（AFE）和高度集成的数据打包系统，可用于NFC-A/B (ISO 14443A/B)读卡器（包括更高比特率）。在流模式下，NFC-V（ISO 15693）读卡器能够以最高53 kbps的速率进行读卡。

ISO 18092被动发起方和目标、以及NFC-A / NFC-F卡模拟也可用来确保终端产品之间的通信。这就使器件能够读写或通过简单的NDEF数据传输与Android™手机交互，或使用Apple^®App Clips。

AFE和数据打包系统的特殊Stream和Transparent模式可在读卡器或卡模拟模式下实现其他自定义协议。

ST25R3918包含一个低功率唤醒模式，通过对天线信号的振幅或相位进行测量来检测天线上是否有NFC卡存在。它还包含一个低功耗RC振荡器和唤醒定时器，可在配置的时间周期过后自动触发器件，也可用于检查标签是否存在。

ST25R3918的设计具有较宽的电源电压范围（-40°C至+105°C为2.6至5.5 V，-20°C至+105°C为2.4至5.5 V）和较宽的外围IO电压范围（1.65至5.5 V）。
