ST25DV-PMW系列动态NFC/RFID标签提供具有脉宽调制（PWM）输出的RFID/NFC非接触式接口。
什么是ST25DV-PWM动态标签？
此类NFC Forum Type 5动态标签在高频（HF）13.56MHz范围内工作，符合NFC Forum的NFC-V Technology规范。存储在这些Type 5标签中的数据原本被传输到NFC智能手机或支持NFC Forum标准化NFC数据交换格式（NDEF）的NFC/RFID HF读卡器。
ST25DV-PWM IC可以通过非接触式接口进行PWM参数的实时更新，从而扩展用户体验。使用ST25DV-PWM IC，无需MCU和外部振荡器，能够显著降低解决方案成本。其他功能，如TruST25TM 数字签名，可确保晶片真实性以及密码保护区域，提供了高级别的安全性和数据完整性。
适用于ST25DV-PWM标签的多种开发者生态系统（评估板、软件工具、移动应用程序等）加快了开发和上市时间。
得益于意法半导体的10年长期供货计划 ，ST25DV-PWM系列可确保10年的持续供应。
