产品概述

描述

在840-960 MHz UHF频段,ST25RU3993 RAIN® (UHF) RFID读卡器设备提供多协议支持,并与ISO18000-62 & -63、ISO29143和GS1的EPC UHF Gen2空中接口协议兼容。它包括一个片上VCO和一个功率放大器,可提供一整套RFID功能,包括密集读写器模式(DRM)功能,并能支持跳频、低电平传输编码、低电平解码、数据成帧和CRC校验。

ST25RU3993可以极低功率运行,这使其适用于便携式和电池供电的设备,如手机。

ST25RU3993采用7x7 mm QFN封装,具有很高的灵敏度,并能抵抗天线反射和自干扰的影响。这对于移动应用和嵌入式应用非常重要,在这些应用中天线设计常受到成本或尺寸的限制。其高灵敏度使得终端产品在使用更简单更便宜的天线时,也能实现其所需的读取范围,从而可以降低整个系统成本。

由于其高度集成性,ST25RU3993仅需一个外部8位微控制器即可创建完整的RFID读写器系统,因此无需复杂的RFID协处理器。
