As the second generation of NXP’s industryleading connected-tag technology, these devices maintain full backward compatibility with first-generation 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. DONE IN AN INSTANT 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’s required is a simple antenna design, with no or only limited extra components, and there are plenty of reference designs online for inspiration. The very small footprint (as low as 1.6 x 1.6 x 0.5 mm) shrinks PCB space and enables very compact designs. ZERO POWER BUDGET NFC tags are passive by default, meaning they can be powered by another device, to save battery power. Energy harvesting even lets the tag power an external device, such as an MCU. The field-detection mechanism enables device wakeup as soon as an NFC field is detected, for longer battery life. Data storage can be done offline, via non-volatile memory, from the NFC or I2C interface. Also, since the NFC interface complies with NFC Forum guidelines, the tag can interact with a full range of NFC-enabled devices. BEST USER EXPERIENCE The integrated SRAM buffer offers faster data transfer than a standard EEPROM, and is a convenient mechanism for managing I2C/NFC communication handoffs while keeping both interfaces active. Fast data transfer is guaranteed by the pass-through mode, which works with the FAST READ and FAST WRITE commands to push data in one shot, and thereby limiting command overhead. The high data-transfer rates, along with reliable multi-interface communication, create smoother end-user interactions. SECURE DATA, CONTROLLED INTERACTIONS Every type of memory access, including the SRAM buffer, can be fully configured for both interfaces. For NFC, a 32-bit password segments the memory into open and restricted access, to secure data according to specified access rights. For I2C, access can be restricted to ensure proper data exchange between embedded electronics and the NFC device. Anticloning protection is supplied by an authentication mechanism based on a 32-byte, ECC-based signature that uses a standard algorithm. The result is easy software integration of the originality check procedure, without the need for specific hardware requirements.
