This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.
ST25DV Dynamic NFC/RFID Tag
ST’s ST25DV is a dynamic NFC and RFID tag that provides fast data transfer between the tag’s host MCU and an NFC phone or reader. The devices can connect to a host MCU over an I2C interface and have a 256 byte buffer that enables the fast transfer mode. The tags have a low power mode and built-in RF energy harvesting that can reduce or eliminate the tag’s use of the power supply and power external components. The devices have an RF range up to 7 cm with NFC and 1 m with RFID, and are ideal for data logging, device programming in production, wireless network commissioning, and service and maintenance applications.
