Enhanced On-Chip Processing MIMO RFIC With 48 Transceivers


Built for autonomous vehicles, the product offers 4D imaging with a 0-300m range that gives a high-resolution point cloud and ultra-wide FoV

This multi-range “XRR” chip from Vayyar Imaging is a single RFIC with a range of 0-300m, designed for passenger cars, trucks and motorcycles. Supported by a 48-antenna MIMO array, the leading-edge platform provides radar imaging with unprecedented accuracy for numerous safety applications, without the need for external processors.

With an ultra-wide field of view and rich 4D point cloud imaging, the XRR chip is unmatched in terms of range, resolution and performance. It delivers unprecedented multifunctionality on a single-chip platform, supporting dozens of Advanced Driver Assistance Systems (ADAS), Advanced Rider Assistance Systems (ARAS) and autonomy features. This eliminates the need for multiple, costly vehicle sensors and reduces costs, complexity, hardware, software, power consumption, wiring and integration efforts.

Affording a range of 0-300m, the multi-range XRR chip differentiates between static obstacles such as dividers, curbs and parked vehicles, and between different types of VRUs, moving vehicles and other hazards.

In low-speed environments such as parking lots, the XRR chip’s uSRR and SRR sensing support advanced parking assistance, scanning the vehicle’s surroundings for pedestrians and obstacles. On the open road, MRR and LRR capabilities facilitate a variety of ADAS and autonomy applications such as Lane Change Assist (LCA), Adaptive Cruise Control (ACC), Blind Spot Detection (BSD), Collision Warnings (fCW/rCW), Cross Traffic Alerting (CTA) and Autonomous Emergency Braking (AEB).

Compared with alternatives such as cameras, standard radar and LIDAR, Vayyar’s 4D imaging radar delivers unprecedented multifunctionality on a single-chip platform, maximising affordability, coverage, range, resolution and robustness. The XRR chip provides real-time 4D detection, identifying and tracking numerous objects simultaneously, even in extremely challenging conditions such as heavy traffic, darkness, or fog.

“Vayyar’s XRR chip delivers unparalleled multi-range capability, reducing complexity and costs, so that high-end safety is 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 computing power necessary for optimal performance, while maintaining cost-efficiency and a compact form factor.”

As automakers strive to protect motorists and their passengers, the AEC-Q100 qualified and ASIL-B compliant multi-range XRR chip is redefining ADAS, ARAS and autonomy, making the utmost safety available to all vehicles.
