产品概述
描述
ST25TN512和ST25TN01K器件是具有TruST25数字签名、增强型NDEF，以及隐私功能的NFC Forum Type 2标签IC。
射频接口符合ISO/IEC 14443-2和14443-3 Type A标准，以及NFC Forum Type 2标签规范。由于其内部调谐电容以及从射频场收集运行功率的能力（由NFC读卡器提供），该器件只需使用天线而无需借助额外组件。
嵌入式电可擦除可编程存储器（EEPROM）可以写入符合NFC Forum规范的NDEF消息，为所有支持NFC功能的手机提供原生触碰读取能力。
增强型NDEF功能允许标签响应动态NDEF消息，无需用户修改EEPROM。
TruST25数字签名有助于打击假冒行为。
Kill功能通过简单的软件程序让标签永久静默，从而保护用户隐私。
在本文档中，术语ST25TN可与ST25TN512或ST25TN01K互换。
