STMicroelectronics, which claims to be the largest supplier of short-range and mid-range (24 GHz) radar chips for Advanced Driver Assistance Systems (ADAS), is now supplying its latest long-range (77 GHz) radar chips to leading automotive customers.

24 GHz systems have spearheaded the introduction of on-board automotive radar by enabling affordable, short-range and mid-range smart-driving features such as blind-spot detection, collision avoidance, and lane-departure warning. ST has delivered over 35 million 24 GHz radar transceiver ICs to date, and continues to build its customer base as more and more markets demand vehicles enhanced with ADAS.

Today’s most developed markets are ready for next-generation features like high-speed adaptive cruise control that require high-power-output, long-range radar, which is best implemented using 77 GHz technology. The higher frequency allows smaller antenna sizes, and permits the same technology to be used for ADAS requiring short-range, medium-range, or long-range radar, hence simplifying system design and reducing time to market.

ST is now building on its success with 24 GHz radar to create a new, highly integrated 77 GHz transceiver that delivers market-leading performance. The device contains three 77 GHz transmitters and four receivers on a single chip, which enables customers to build smaller, lower-cost, and less complex systems. The multi-channel architecture of ST’s new 77 GHz radar chip enhances object recognition and resolution that translates into superior performance and dependability on the road.

Marco Monti, Executive Vice President, General Manager, Automotive and Discrete Product Group, STMicroelectronics, said, “We have leveraged our technology and success in ADAS markets to create the industry’s most highly integrated 77 GHz radar transceiver. Our customers designing-in this device are positioned strongly, as demand for 77 GHz technology in advanced markets is growing in mid-market and lower-cost vehicle platforms.”

ST is now sampling its multi-channel single-chip 77 GHz radar transceiver to lead customers and is preparing to enter volume production in March 2017.
