Introduction

The dynamic NFC interface transponder RF430CL330H is an NFC Tag Type 4 device that combines a wireless NFC interface with a wired SPI or I2C interface to connect the device to a host. NDEF messages in SRAM can be read and written via the integrated SPI or I2C serial communication interface, or wirelessly accessed and updated through the integrated ISO 14443B RF interface supporting data rates up to 848 kbps.

This mode of operation intuitively simplifies NFC handover to an alternative carrier — for example, enabling Bluetooth, BLE, and Wi-Fi pairing or authentication processes with just a tap. As a universal NFC interface, the RF430CL330H enables end devices to communicate with the rapidly expanding infrastructure of NFC-enabled smartphones, tablets, and laptops.
