Enabling developers to bring the ease of NFC to automotive infotainment systems, Texas Instruments has announced the industry’s first dynamic dual interface NFC transponder with Q100 automotive qualification. The RF430CL330H-Q1 transponder enables Simple Secure Pairing (SSP) using the Out of Band (OOB) association model for Bluetooth, Bluetooth Smart and WiFi between an NFC-enabled smartphone or tablet and an automotive infotainment system.

Pair and connect or execute NFC-enabled WiFi Protected Setup (WPS) with one tap to configure specific driver settings when entering the car, eliminating complicated manual procedures.

An optimised NFC interface can also serve as a secure configuration and service interface for diagnostics data, supporting 106, 212, 424 and 848 kBaud data rates to allow maximum communication flexibility. The RF430CL330H-Q1 supports an I2C or serial peripheral interface (SPI) connection to an infotainment host processor in the vehicle, including the DRA74x “Jacinto 6” or DRA72x “Jacinto 6 Eco” automotive System-on-Chips (SoCs) from Texas Instruments.

The RF430CL330H-Q1 dynamic dual interface NFC transponder interface is available for USD $0.62 at 1,000 unit volumes.  Developers can begin evaluating their NFC designs using the RF430CL330H-Q1 dynamic NFC transponder interface with the RF430CL330HTB target board for USD $19.
