NT3H2111W0FTT: NTAG I²C plus, NFC Forum Type 2 Tag with I²C interface optimized for entry-level NFC applications

The NTAG I²C plus combines a passive NFC interface with a contact I²C interface. Designed to be the perfect enabler for NFC in home-automation and consumer applications, this connected NFC tag is the fastest, least expensive way to add tap-and-go connectivity to just about any electronic device.

These devices maintain full backward compatibility with first-generation NTAG I²C, while adding advanced features for password protection, full memory-access configuration from both interfaces, and an originality signature for protection against cloning.
