ON Semiconductor has announced that its AR0820AT 8 MP image sensors and SiPM arrays for LiDAR sensors are the power key functions of AutoX’s Gen5 self-driving platform. AutoX RoboTaxis are equipped with 28 high-resolution 2D image sensors and four 3D LiDAR sensors that provide a full surround view with zero blind spots and ensure the highest level of safety. The AR0820AT 8 MP image sensor enables high-resolution camera fusion with other sensors and includes functions such as in−pixel binning, windowing, and both video and single frame modes to provide flexible Region of Interest (ROI) or specific resolution in order to enhance performance in extreme low light conditions. 

 

AR0820AT is a 1/2−inch CMOS digital image sensor with a 3848H x 2168V active−pixel array. This advanced automotive sensor captures images in either linear or high dynamic range, with rolling−shutter readout. It is optimized for both low light and challenging high dynamic range scene performance, with a 2.1µm DR−Pix BSI pixel and on−sensor 140dB HDR capture capability. The device is programmable through a simple two−wire serial interface and supports MIPI output interface.
