NBT2000 OPTIGA™ NBT NFC Bridge Tag

Infineon Technologies NBT2000 OPTIGA™ NBT NFC Bridge Tag is a ready-to-use dual-interface bridge tag with a contactless passive NFC interface and an I²C target interface to the MCU. The device supports high-performance NFC-to-I²C communication. The Infineon Technologies NBT2000 OPTIGA™ NBT NFC Bridge Tag comes with an NFC Forum Type 4 tag-compliant 8KB file system with file-based password protection, one-way authentication using ECDSA asymmetric cryptography, and symmetric AES-128-CMAC-based cryptography. The NBT2000 can be powered by an external NFC field, where the NFC reader connects to the NFC tag application via the contactless interface (L_A, L_B) and an externally connected antenna. In addition to the NFC interface, the device can also be supplied from an external power supply (V_CC, GND), including an integrated I²C interface and one IRQ for communication with external host systems.
