New ST25DV-I2C series improves on M24LR dynamic NFC tags with new features

ST's new ST25DV-I2C series is an upgrade of our M24LR series of dynamic NFC tags. Offering a 13.56 MHz long-range interface compatible with NFC phones and readers, our new ST25DV-I2C dynamic NFC/RFID tags feature an innovative fast transfer mode, an I²C interface up to 1 MHz and an extended temperature range up to 125 °C.

Backward compatible with the M24LR series and designed for a simple antenna design, ST25DV-I2C dynamic tags are available in new packages including a 12-pin UFDFPN and a very thin 10-ball WLCSP.
