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.
