NFC transponder targets automotive applications

December 04, 2015 // By Christoph Hammerschmidt
Texas Instrument has introduced a Transponder for the Near Field Communication (NFC) technology with Q100 automotive qualification. The dynamic dual interface device will bring the simplicity and productivity of the NFC technology to the automotive domain, the chipmaker said.

The RF430CL330H-Q1 transponder enables Simple Secure Pairing (SSP) according to the Out of Band (OOB) association model for Bluetooth, Bluetooth Smart and WiFi links between an NFC-enabled smartphone or tablet and an automotive infotainment system. Pair and connect or execute NFC-enabled Wi-Fi Protected Setup (WPS) with one tap to configure specific driver settings when entering the car, eliminating complicated manual procedures.

An optimized 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 transponder is available now. For evaluation of NFC designs, TI also provides a developer board, available under the type designation Target Board RF430CL330HTB. Additional documentation and training material can be found here.
