Provides 100,000 electrons of full-well capacity, includes LFM and on-chip HDR

OnSemiconductor has introduced a CMOS image sensor platform that delivers a new level of performance and image quality for automotive applications such as ADAS, mirror replacement, rear and surround view systems, and autonomous driving.

The Hayabusa platform features a groundbreaking 3.0-micron backside-illuminated pixel design that provides the industry's highest 100,000 electrons of full-well capacity. Key features of this device include LED flicker mitigation (LFM) and on-chip HDR, as well as real-time functional safety and automotive grade qualification.

Ross Jatou, Vice President and General Manager of OnSemiconductor's Automotive Solutions division, stated: "The Hayabusa product family enables automotive manufacturers to meet evolving ADAS standards such as Euro NCAP 2020 and provides next-generation capabilities including electronic mirrors, high-resolution surround view systems, and anti-flicker technology. The scalable sensor with optical sizes ranging from 1/2" to 1/4" can be applied across multiple types of automotive platforms, allowing customers to reduce development time and effort while shortening time-to-market."

He added: "OnSemiconductor has been supplying image sensors with this pixel architecture for high-end digital cameras used in cinema and television production. We have applied this proven architecture to new sensors developed from the ground up for automotive standards."

The high full-well capacity of this pixel design enables the Super-Exposure function, which allows all Hayabusa family devices to provide 120dB HDR imaging with LFM for high image fidelity in the most challenging scenes without sacrificing low-light sensitivity. The simultaneous HDR and LFM capabilities represent a critical function that enhances safety by identifying all objects and potential hazards in both very dark and very bright areas of a scene.

The platform's LFM function across various LEDs, from front and rear lights to traffic signals, effectively prevents flicker from pulsed light sources that could distract the driver or cause misinterpretation by machine vision algorithms in forward-facing ADAS scenarios.

The Hayabusa product family also features safety capabilities that comply with ISO26262 requirements in real-time, enabling the sensor to immediately alert the system processor if any issues or potential errors occur. These features enable system designs rated up to ASIL-C. Real-time functionality allows immediate identification of errors instead of transmitting the entire image to the processor and waiting for image analysis.

The faster response time enables the system processor to take immediate corrective action to address issues. This capability is critical given that vehicles traveling on highways easily cover 100 feet in less than one second.
