AR0331 1/3-Inch 3.1 Mp/Full HD Digital Image Sensor

■onsemi AR0331 is a 1/3-inch CMOS digital image sensor with an active pixel array of 2048 (H) x 1536 (V). It captures images in linear or high dynamic range mode with rolling shutter readout. It includes sophisticated camera features such as pixel binning, windowing, and video and single frame modes. It is designed for low light and high dynamic range scene performance. It can be programmed via a simple two-wire serial interface. The ARQ331 produces very clear and crisp digital images and is capable of capturing both continuous and single frame video, making it a perfect choice for a wide range of applications including surveillance and high definition video.

■onsemi AR0331 can operate in default mode or can be pin programmed for frame size, exposure, gain, and other parameters. The default mode outputs 1080p resolution images at 60 frames per second (fps). In linear mode, it outputs 12-bit or 10-bit A-law compressed raw data using either parallel or serial (HiSPi) output ports. In high dynamic range mode, it outputs 12-bit compressed data using parallel output. in HiSPi mode. 12-bit or 14-bit compressed or 16-bit linearized data can be output. The device can be operated in video (master) mode or single frame trigger mode.

■FRAME_VALID and LINE_VALID signals are output on dedicated pins, along with a synchronous pixel clock output in parallel mode.

■The AR0331 includes additional features that allow application-specific adjustments: windowing and offset, automatic black level correction, and an on-board temperature sensor. Optional register information and histogram statistics can be embedded in the first and last two lines of the image frame.

■The sensor is designed to operate over a wide temperature range (-30°C to +85°C).
