Infineon’ NBT2000 OPTIGA NBT NFC bridge tag available from Mouser
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 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.
It can be powered by an external NFC field, where the NFC reader connects to the NFC tag application via the contactless interface (LA, LB) and an externally connected antenna. In addition to the NFC interface, the device can also be supplied from an external power supply (VCC, GND), including an integrated I2C interface and one IRQ for communication with external host systems.
