ON Semiconductor has introduced CMOS image sensor platform, called Hayabusa platform. The company claims it to be world’s first highly scalable family of Next-Generation Automotive Image Sensors and is expected to bring new levels of performance and image quality to automotive applications such as ADAS, mirror replacement, rear and surround view systems, and autonomous driving.
Hayabusa platform delivers simultaneous 120 dB ultra-high dynamic range (UHDR) with LED flicker mitigation (LFM) imaging in a range of sizes from 1 MP to 5 MP. It features 3.0-micron backside illuminated pixel design that delivers a charge capacity of 100,000 electrons, the highest in the industry, with other key automotive features such as simultaneous on-chip high dynamic range (HDR) with LED flicker mitigation (LFM), plus real-time functional safety and automotive grade qualification.
The high charge capacity of this pixel design enables every device in the Hayabusa family to deliver Super-Exposure capability, which results in 120-decibel (dB) HDR images with LFM for high image fidelity in the most challenging scenes without sacrificing low-light sensitivity. The simultaneous HDR and LFM capability is especially important in enhancing safety, as it ensures that all objects and potential hazards can be identified in both very dark and very bright areas of the scene.
The Hayabusa product family also features real-time, ISO26262-compliant functional safety capabilities to alert the system processor if the sensor has any issues or potential errors. These features enable system designs rated up to ASIL-C. The real-time capability enables errors to be identified immediately rather than waiting for the full image to be transferred to the processor and then waiting for image analysis. This faster response time means the system processor can take immediate action to remedy the issue, which is crucial when considering that a vehicle moving on a freeway easily covers 100 feet in less than one second.
