Compatible with All Existing ISO 15693 RFID Infrastructure
Suitable for Industrial Applications with High Write-Cycle Durability

STMicroelectronics (hereinafter ST) has launched the ST25DV dynamic tag IC, which features a versatile contactless RF interface and an I2C bus.

This product is added to the existing ST25 NFC/RFID product family, and thanks to its dual interface (RF+I2C), it enables close interaction between NFC-enabled smartphones or RFID readers and the host microcontroller embedded in nearby devices.

ST's ST25DV IC supports data exchange over an extended communication range, enabling on-site software updates via NFC-enabled mobile devices using Fast Transfer Mode operation, and allowing "in the box programming" of electronic equipment during production. The ST25DV dynamic tag is compatible with all existing ISO 15693 RFID infrastructure, eliminating the need for additional investment.



The ST25DV series supports both NFC Type 5 and ISO 15693 RFID specifications, providing the most powerful features for each specification. It offers native NFC NDEF message support and fast transfer mode driven by a large 256-byte buffer, enabling long-range ISO 15693 RF connectivity. Additionally, it provides enhanced data protection through the industry's largest 64Kbit EEPROM capacity and multiple 64-bit passwords.

With data retention of 40 years at 25°C and high write-cycle durability of 1 million cycles, it is suitable for industrial applications. It operates over a wide I²C supply voltage range of 1.8V to 5.5V and consumes less than 1µA of power in standby mode, minimizing energy consumption across all modes, making it applicable to power-sensitive or battery-operated devices. With energy harvesting capabilities, it is an ideal solution for implementing zero-power applications.
