ON Semiconductor has announced new CMOS image sensors to address the spectrum of applications for Advanced Driver Assistance Systems (ADAS) and autonomous driving. The sensors offer resolutions scaling from 8.3 MP down to 1.2 MP with a low-light performance from 4.2 µm pixels.
The AR0820AT, AR0220AT and AR0138AT image sensors provide a range of resolutions suited to new-generation ADAS and autonomous driving systems.
“Automakers need different resolutions to address segmentation in their product lines, where specific safety features are standard, but additional cameras or higher resolution cameras enable more advanced safety and luxury capabilities as customer options”, the announcement stated.
The automotive industry is moving from Level 2 systems for emergency autonomous braking, adaptive cruise control and lane change assistance towards fully autonomous driving. According to the firm, the new sensors are suited to provide these capabilities.
Additional features of the sensors include functional safety up to ASIL-C, high-dynamic range (HDR), a cybersecurity option, and a wafer stacking technology that reduces package size.
The large 4.2 µm pixel is claimed to offer good performance in low-light scenarios such as night-time emergency braking for pedestrians and cyclists that is being added to safety tests defined by Euro NCAP.
“In addition, cybersecurity included in the products helps ensure reliable and secure operation when multiple cameras around the vehicle are connected to a centralized system where data and commands must travel by wires between the sensor and the processor”, the company said.
“As the number of image sensors on a vehicle increases, having a scalable platform with common core features and pixel architecture becomes even more important for automakers to deliver new safety and self-driving features to market quickly and efficiently,” said Ross Jatou, vice president and general manager of the Automotive Solution Division at ON Semiconductor. “Our deep engagement with customers and the advanced features of our new image sensor family enable them to bridge development efforts across ADAS and autonomous driving programs.”
Individual products in this platform are currently under evaluation by many technology partners, including Mobileye and NVIDIA for use with its DRIVE AI computing platform for autonomous vehicles.
ON Semiconductor will demonstrate the new image sensors along with a wide range of other semiconductor- solutions for automotive and other sectors during CES 2018.
