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. The NTAG I2C plus 2K in XQFN8 is a derivate of the NTAG I2C plus product and has 1912 bytes freely available with a User Read/Write area (478 pages with 4 bytes per pages).
