The Texas Instruments Dynamic NFC Interface Transponder RF430CL330H is an NFC Tag Type 4 device that combines a wireless NFC interface and a wired serial peripheral interface (SPI) or inter-integrated circuit (I2C) interface to connect the device to a host. The NDEF message in the SRAM can be written and read from the integrated SPI or I2C serial communication interface (for example, via a microcontroller) and can also be accessed and updated wirelessly via the integrated ISO14443B-compliant RF interface. The RF Interface supports data rates up to 848 kbps. The device allows for applications including, but not limited to, NFC connection handover for an alternative carrier like Bluetooth, Bluetooth Low Energy (BLE), and Wi-Fi as an easy and intuitive pairing process or authentication process with only a tap. As a general use NFC interface, the RF430CL330H enables end-equipment to communicate with the fast growing infrastructure of NFC-enabled smart phones, tablets, and notebooks.
