General Description
onsemi AR0821 is a 1/1.7−inch CMOS digital image sensor with a
3848 H x 2168 V active−pixel array. This advanced sensor captures
images in either linear or high dynamic range, with rolling−shutter
readout. AR0821 is optimized to deliver high−quality performance in
both low−light and challenging lighting conditions. It is supported by
a 2.1 m Dual Conversion Gain Pixel Technology (DR−Pix) BSI
pixel from onsemi and embedded HDR (eHDR) technology that
delivers greater than 140 dB. The sensor includes advanced functions
such as in−pixel binning, windowing, and both video and single frame
modes to provide flexible Region of Interest (ROI) or specific
resolution providing enhanced performance in extreme low light
conditions. The device is programmable through a simple two−wire
serial interface, and supports MIPI output interface.
