Vayyar releases the world’s first MIMO single-chip “XRR” RFIC with 48 transceivers and on-chip processing

Vayyar’s XRR chip – AEC-Q100 qualified and ASIL-B compliant – is unmatched for range, resolution, and performance. With an ultra-wide field of view and rich 4D point cloud mapping, it offers unparalleled multifunctionality on a single-chip platform and supports dozens of Advanced Driver Assistance Systems (ADAS), Advanced Rider Assistance Systems (ARAS) and autonomy functions. This eliminates the need for several expensive vehicle sensors and reduces costs, complexity, hardware, software, power consumption, cabling and integration effort.

A range from 0-300mThe multi-range XRR chip distinguishes between static obstacles such as partitions, curbs and parked vehicles, as well as between different types of VRUs, moving vehicles and other hazards. In low-speed environments such as parking lots, the uSRR and SRR detection of the XRR chip supports the advanced parking aid by scanning the vehicle’s surroundings for pedestrians and obstacles. On the open road, the MRR and LRR functions facilitate a large number of ADAS and autonomy applications such as lane change assistant (LCA), adaptive cruise control (ACC), blind spot detection (BSD), collision warnings (fCW / rCW), cross traffic alerting (CTA) and autonomous Emergency braking (AEB).

“Vayyar’s XRR chip offers unparalleled multi-domain capabilities, reducing complexity and cost, making high-end security accessible and affordable for all vehicle models,” said Ian Podkamien, VP and Head of Automotive at Vayyar. “To achieve this, we integrated 48 transceivers into a single chip, along with the processing power required for optimal performance while being cost-effective and in a compact form factor.”

Only two XRR chips earn each vehicle 33 euros NCAP safety points while replacing over ten conventional ADAS sensors. Vayyar’s platform supports nine different Euro NCAP ADAS requirements for 2023, protecting pedestrians, cyclists and motorcyclists while maximizing safety ratings.

Compared to alternatives such as cameras, standard radar and LIDAR, Vayyar’s 4D imaging radar offers unparalleled multifunctionality on a single-chip platform, maximizing affordability, coverage, range, resolution and robustness. The XRR chip offers 4D detection in real time and identifies and tracks numerous objects at the same time, even in extremely difficult conditions such as heavy traffic, darkness or fog.

As automakers strive to protect drivers and their passengers, Vayyar’s multi-domain XRR chip is redefining ADAS, ARAS and autonomy, bringing the highest levels of security to all vehicles.

About Vayyar Imaging (Automotive)

Vayyar’s intelligent sensors create holistic cab and ADAS safety opportunities by using automotive-grade 4D imaging radar technology. The “fourth dimension” refers to the ability to capture movement, time and speed. The heart of these sensors is a powerful radar-on-chip that supports up to 48 transceivers for exceptional resolution. With an ultra-wide field of view, Vayyar’s 60 GHz and 79 GHz single-chip radar modules cover large areas to reduce the number of sensors in vehicles. They offer comprehensive detection in and around the vehicle and track multiple targets and objects at the same time. Vayyar technology is multifunctional, affordable, and available for mass production. The radar-based platform is robust in all road conditions while protecting user privacy. Vayyar plans to advance the next generation of sensor technology that is small, affordable, and versatile enough to enable a safer world.

Editor’s Notes

In contrast to conventional radar solutions with 2 to 3 transmitting antennas and 3 to 4 receiving antennas, the 4D imaging radar uses a 48-antenna array with multiple inputs and multiple outputs for high-resolution mapping of its surroundings. The rich point cloud data output in combination with an ultra-wide azimuth elevation field of view enables precise detection and tracking and is therefore the ultimate sensor for the road in front of and behind.
