TW: Would you like to discuss some of your offerings in the automotive segment?

Addy: Dialog Semiconductor offers best-in-class Bluetooth low energy solutions that are ideal for the automotive market from both a performance and quality perspective. Dialog’s solution are primarily aimed at the Tire Pressure Monitoring Systems (TPMS), OBD dongles and Remote Key Entry (RKE) applications.

Dialog’s DA14585 device has recently been adopted by two internationally-recognized suppliers for TPMS. The device, which is based on low power ARM Cortex M0, is capable of capturing the data from the accelerometer, pressure and temperature sensors and securely sending it to the car or a smartphone without the need for an additional microcontroller.

By using the Bluetooth low energy standard through a smart low power architecture, the DA14585 enables to send the data across in a very efficient way, thereby guaranteeing the long battery lifetime needed by the TPMS systems. Furthermore, the DA14585 is available in a tiny 2.4 x 2.7mm WL-CSP package, which enables manufacturers to produce innovative form factors such as screw-cap TPMS systems that fit directly onto the valve of the wheel.

TW: How do you think Bluetooth can be made attractive for the car industry? Can you please comment on the opportunities and challenges?

Addy: Here are some of the key benefits to utilizing Bluetooth within the automotive industry:

  • It is a worldwide standard, so only one single application platform needs to be developed
  • All Bluetooth functions can connect to a single base inside the car, which reduces complexity and cost
  • Bluetooth enables two-way communication, omitting the need for dedicated tools and therefore reducing tooling complexity and cost
  • Bluetooth enables a higher level of security than the existing RF solutions
  • It directly connects devices like smartphones to the vehicle with ease

TW: What are the opportunities for semiconductor business in the automotive segment?

Addy: Within the car industry, trends such as autonomous vehicles, continuous safety and prevention system improvements and enhanced comfort are fueling the demand for more electronic content.

On all fronts, the semiconductor content is increasing and the trend is likely to continue for years to come. Additional sensors, more processing power, enhanced power management and robust wireless connectivity are just some of the technology aspects that will see strong demand in the automotive segment.

Specifically, for wireless connectivity, Bluetooth low energy semiconductor vendors will see a strong demand in the years to come as the standard starts being adopted to introduce the use of the Smartphone as a key to the car. TPMS systems, described above, will also benefit from the use of the standardas they will enjoy longer battery lifetimes and pressure readout on the car owner’s smartphone.

With its state-of-the art Bluetooth low energy solutions and a long legacy in the automotive market as a provider of motor control ICs, Dialog Semiconductor sees an excellent opportunity to support the automotive market’s move into the next phase of connectivity.
