The Infineon Technologies OPTIGA Authenticate NBT is a high-performance NFC I2C bridge tag to secure human-machine interfaces (HMIs). The bridge tag enables fast, contactless NFC communication between an IoT device with an I2C interface and a contactless NFC reader such as a smartphone.
A Type 4 Tag certified by the NFC Forum, the OPTIGA Authenticate NBT can be used for single-tap authentication and secured configuration of an IoT device via an app on the user’s smartphone. The bridge tag provides high security, thanks to its acclaimed Integrity Guard 32 security architecture.
The NFC-I2C bridge tag supports both symmetric and asymmetric cryptographic authentication, as well as pass-through and asynchronous data communication modes. These can be used for a variety of applications such as:
Featuring an 8kbyte non-volatile memory, the NFC I2C bridge tag offers ample space to store customer- and application-specific configuration information. High on-chip capacitance enables the use of a smaller antenna to lower bill-of-materials cost and reduce board footprint.
Part Number: NBT2000A8K0T4KITV1TOBO1
The OPTIGA™ Authenticate NBT development kit from Infineon Technologies is ideal for the quick and simple evaluation of the OPTIGA Authenticate NBT using example applications available through GitHub. These example applications include code for smartphones based on the Android™ or iOS operating systems.
The kit simplifies the development of custom applications using a PSOC™ host microcontroller based on the example applications. After detaching the adaptor board, the shield may also be used separately for evaluation and application development using other MCU boards.
