The new ST25DV dynamic-tag ICs are the latest addition to STMicroelectronics’ NFC/RFID product family that come with a rich featured contactless RF interface and I²C bus. The dual interface enables untethered interaction between an NFC-capable smartphone or an RFID reader and the host microcontroller located inside nearby equipment, such as smart meters, IoT devices, professional or consumer products. The ICs support data exchange with extended communication range enabling ‘in the box’ programming of electronic equipment at the point of production, as well as fast transfer mode operation for software updates in the field with the help of any NFC-enabled mobile device. The tags are compatible with any existing ISO 15693 RFID infrastructure.
