ST25DV Series Dynamic NFC Tags

Overview:

The ST25DV series of dynamic NFC/RFID tags offers a 13.56 MHz long-range interface compatible with NFC phones and readers.

Based on an ISO/IEC 15693 and NFC Forum Type 5 tag, ST25DV tag ICs can be operated from an RFID reader or an NFC phone. They also include an I²C interface that lets them connect to a host (MCU, MPU, etc.).

These tags feature an innovative fast transfer mode between an embedded host and an NFC phone or reader thanks to their half-duplex 256-byte buffer.

ST25DV dynamic NFC/RFID tags can be used in a wide variety of applications including consumer electronics, industrial, metering, electronic shelf labels, IoT objects and more.
