ST25 Dynamic NFC Tags

Product selector
CAD Resources
Tools & Software

ST’s dynamic NFC / RFID tags feature up to 64-Kbit of EEPROM memory which can be accessed either through an RF contactless interface operating at 13.56 MHz or a low-power I²C interface except for ST25DV-PWM series (PWM outputs). Both short-range (ISO14443-A) and long-range (ISO15693) standards are supported.

  • ST25DV-I2C series: ISO15693 NFC forum type 5 certified dynamic tags suited for consumer electronics, industrial, metering, lighting, healthcare, home appliance, electronic shelf labels IoT objects and more.
  • ST25DV-PWM series: ISO15693 NFC forum type 5 certified dynamic tags with Pulse Width Modulation (PWM) outputs suitable for industrial configuration application.
product longevity

The benefit of our 10 years longevity program is available to a part of the devices making them suitable for deployment in Industrial-grade and Medical NFC / RFID applications.
