Our connected tag solutions portfolio contains both, passive HF and UHF interfaces. The NTAG® family complies to NFC Forum and the UCODE® family to EPCGlobal Gen. 2 standard. Next to the contactless interface, all connected tags have additional interfaces like field detection or I2C to connect to your embedded system. On top NTAG I2C plus can be used to power the embedded system by the HF field

While our NTAG® products are a good choice for any applications that are meant to communicate with smartphones, our UCODE I2C is best suited for industrial environments, where much longer reaches for data transfer are needed than usually enabled with NFC.

The NTAG F portfolio is particularly well suited for use with battery-powered systems, such as speakers and headsets, where it can wake the system and initiate Bluetooth or WiFi pairing.

The NTAG I2C plus portfolio supports full bidirectional communication between an NFC-enabled device and the host system’s microcontroller, making it an ideal solution for NFC implementations that interface with a range of electronic devices. An innovative energy-harvesting function, which makes it possible for the NTAG I2C plus tag to power external components, like a microcontroller, makes NTAG I2C an excellent choice for low-power applications.

The UCODE I2C combines two independent UHF Interfaces (following EPCGlobal Gen. 2) with an I2C interface. Its large memory can be then read or written via both interfaces. This I2C functionality enables the standard EPCGlobal Gen. 2 functionalities to be linked to an electronic device microprocessor.
