Infineon Launches NFC I2C Bridge Tag for IoT Devices

Munich, Germany – Infineon Technologies AG launched the OPTIGA™ Authenticate NBT, a high-performance NFC I2C bridge tag for single-tap authentication and secured configuration of IoT devices. According to the company, it is the only asymmetric cryptography tag for signing and verifying operations in the market, and it is certified as a Type 4 Tag by the NFC Forum.

OPTIGA Authenticate NBT enables data exchange with large data volumes. It allows contactless NFC (Near Field Communication) communication between IoT devices and contactless readers such as smartphones. It can be used for various applications, such as secured configuration of electronic devices without a display, activation of shared mobility vehicles, passive commissioning of unpowered smart light bulbs before installation, and data logging on patient health monitors.

OPTIGA Authenticate NBT offers superior security with Infineon’s Integrity Guard 32 security architecture and the EAL6+ certification for both the hardware and the crypto libraries. The tag supports symmetric and asymmetric cryptographic authentication and pass-through and asynchronous data transfer modes.

The device uses TEGRION™ hardware and enables a contactless interface speed of up to 848 Kbit/s and an I2C interface that supports up to 1 Mbits/s which results in the best performance values, particularly important for demanding applications. The NFC I2C bridge tag offers 8 KB of generous memory to store customer and application-specific configuration information. In addition, the high on-chip capacitance enables smaller antenna designs, optimizing both BOM costs and space requirements.

Samples of OPTIGA Authenticate NBT are available now, and the devices will become available to the broader market in August 2024.

The OPTIGA Authenticate NBT Development Shield and the OPTIGA Authenticate NBT development kit are also available to facilitate evaluation and design-in. In addition, developers can access technical documentation and extensive host-side integration support without having to sign a non-disclosure agreement (NDA). Infineon also offers training for the security products.
