NT3H2111_2211 NTAG I2C plus: NFC Forum T2T with I2C interface, password protection and energy harvesting Rev. 3.5 — 7 May 2019 Product data sheet 359935 COMPANY PUBLIC 1 General description Designed to be the perfect enabler for NFC in home-automation and consumer applications, this feature-packed, second-generation connected NFC tag is the fastest, least expensive way to add tap-and-go connectivity to just about any electronic device. NXP NTAG I2C plus is a family of connected NFC tags that combine a passive NFC interface with a contact I2C interface. As the second generation of NXP’s industry leading connected-tag technology, these devices maintain full backward compatibility with firstgeneration NTAG I2C products, while adding new, advanced features for password protection, full memory-access configuration from both interfaces, and an originality signature for protection against cloning. The second-generation technology provides four times higher pass-through performance, along with energy harvesting capabilities, yet NTAG I2C plus devices are optimized for use in entry-level NFC applications and offer the lowest BoM of any NFC solution. I2C and NFC communications are based on simple, standard command sets, and are augmented by the demo board OM5569/NT322E, which includes online reference source code. All that is required is a simple antenna design (see Ref. 5), with no or only limited extra components, and there are plenty of reference designs online for inspiratio...
