ST25DV Dynamic NFC/RFID Tag - STM


STMicroelectronics ST25DV Dynamic NFC/RFID Tag

STMicroelectronics ST25DV Dynamic NFC/RFID Tag is a dual interface, fast transfer mode, energy harvesting device that has a configurable interrupt capability, RF management and low power mode. The ST25DV embeds an EEPROM memory and a dedicated memory buffer for fast data transfer. The tag can be operated from an I2C interface or by a 13.56MHz RFID reader or a NFC phone. The I2C two-wire interface behaves as a slave in the I2C protocol. The contactless interface is compatible with ISO/IEC 15693 standard and NFC Forum type 5 tag.

Features
  • ISO/IEC 15693 and NFC Forum Type 5 tag contactless interface
  • 1-MHz I2C serial interface operating from 1.8 to 5.5V
  • EEPROM memory density from 4 to 64Kbits
  • Fast Transfer mode thanks to 256-byte buffer

  • Energy harvesting feature
  • 64-bit password protection
  • GPO interruption pin configurable on multiple RF events
  • Simple antenna design, backward compatible with M24LR series
