The ST25DV-I2C series of Dynamic tags offers both an NFC/RFID contactless interface and an enhanced I²C wired interface for connecting to a host, such as a microcontroller or microprocessor.
What is the ST25DV-I2C series?
These NFC Forum Type 5 Dynamic tags operate in the high-frequency range (13.56 MHz). The data stored in tags can be accessed by any NFC smartphone or NFC/RFID HF professional reader, and also by an MCU, using the I2C wired link.
ST25DV-I2C tags offer rapid writing, fast transfer mode, enhanced I²C features, energy harvesting, low power mode, and password protection. Thanks to this rich feature set, these highly integrated and cost-effective tags are suitable for a wide range of applications.
Moreover, developers benefit from a complete ecosystem with evaluation boards, software tools, mobile app, and other resources to speed up application development.
ST25DV-I2C series is in the ST 10 year longevity program that ensures continuous supply for 10 years.
ST25DV-I2C series products are suitable for a broad range of applications in industrial or consumer domains.
Its rich feature set, including fast transfer mode (between NFC and I²C interfaces), NFC Forum type 5 support, highly reliable EEPROM memory, energy harvesting capabilities, and large package range ensure that the ST25DV-I2C series can meet various customer application needs.
