AR0238 AR0238: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor General Description www.onsemi.com ON Semiconductors AR0238 is a 1/2.7-inch CMOS digital image sensor with an activepixel array of 1928Hx1088V. It captures images in either linear or high dynamic range modes, with a rollingshutter Features readout. It includes sophisticated camera functions such as inpixel Superior Low light Performance binning, windowing and both video and single frame modes. It is Latest 3.0 m Pixel with designed for both low light and high dynamic range scene performance. It is programmable through a simple twowire serial ON Semiconductor DRPix Technology interface. The AR0238 produces extraordinarily clear, sharp digital with Dual Conversion Gain pictures, and its ability to capture both continuous video and single Full HD Support at up to 1080P 60 fps for frames makes it the perfect choice for a wide range of applications, Superior Video Performance including surveillance and HD video. Linear or High Dynamic Range Capture Supports Line Interleaved T1/T2 readout to Table 1.

The ON Semiconductor AR0238 can be operated in its Optional register information and histogram statistic default mode or programmed for frame size, exposure, gain, information can be embedded in the first and last 2 lines of and other parameters. The default mode output is a 1080p the image frame. resolution image at 60 frames per second (fps) through the The AR0238 is designed to operate over a wide HiSPi port. In linear mode, it outputs 12bit or 10bit temperature range of 30C to +85C ambient. ALaw compressed raw data, using the parallel or serial FUNCTIONAL OVERVIEW (HiSPi) output port. In high dynamic range mode, it outputs The AR0238 is a progressivescan sensor that generates two exposure values that the ISP will combine into an HDR a stream of pixel data at a constant frame rate. It uses an image. The device may be operated in video (master) mode onchip, phaselocked loop (PLL) that can be optionally or in single frame trigger mode. enabled to generate all internal clocks from a single master FRAME VALID and LINE VALID signals are output on input clock running between 6 and 48 MHz.
