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.
