RF ICs for Vehicle Communication Service

Toshiba offers RF ICs specifically designed for various vehicle communications. These ICs provide voice navigation about traffic jams, accidents, highway junctions, etc. in real time and allow enrolled vehicles to pass through tollbooths without having to stop to pay. Thus, they help to improve the driving experience.

  • Electronic Toll Collection (ETC) Systems
  • Dedicated Short-Range Communications (DSRC)
  • Multi-Lane Free Flow (MLFF): Allows drivers on multiple adjacent lanes to communicate without having to slow down to pay the toll, without the use of tollgates.

RF IC Systems for ETC, ETC2.0 and DSRC Applications

  • High-speed channel-frequency switching and support for Korean ETC systems
  • Can be used for both DSRC and ETC applications because the functionality of ASK and QPSK has been combined into a single circuit

Chinese ETC transponder systems are usually battery-operated. Thus the ICs in the systems are required low-current consumption and low-voltage operation. To reduce current consumption, the TC32168FTG incorporates a wakeup capability that wakes up a microcontroller only when it detects a signal from an ETC gate. Additionally, the TC32168FTG features low-voltage operation, quick boot, simultaneous two-channel standby mode and so on.
