The onsemi AR0823AT is a 1/1.8-inch CMOS digital image sensor with a 3840 H x 2160 V active−pixel array. This advanced automotive sensor captures images in high dynamic range (HDR) with LED flicker mitigation (LFM). The AR0823AT is able to capture both low light and extremely bright illumination in every frame with a 2.1 µm super-exposure pixel. This pixel enables up to 150 dB of dynamic range without the need for auto exposure adjustment. This significantly reduces latency in scene dependent critical automotive systems, enabling faster and safer data gathering and decision-making. A dual output data path can be used to send both 8 MP and scaled or windowed images simultaneously for both ADAS systems and viewing applications, removing the need for two cameras. The sensor includes flexible functions such as smart ROI, binning, windowing, and can achieve 60 frames per second in full resolution. The sensor is designed following ASIL D design processes, and the sophisticated real time safety mechanisms and fault detection features on the AR0823AT exceed ASIL B hardware metrics.
