The MCM20027 is a fully integrated, high performance CMOS image sensor with features such as integrated timing,
control, and analog signal processing for digital imaging applications. The part provides designers a complete im-
aging solution with a monolithic image capture and processing engine thus making it a true “camera on a chip”. Sys-
tem benefits enable design of smaller, portable, low cost and low power systems. Thereby making the product
suitable for a variety of consumer applications including still/full motion imaging, security/surveillance, and automo-
tive among others.
The imaging pixels are based on active CMOS pixels using pinned photodiodes that are realized using Motorola’s
sub-micron ImageMOS
the frame rate is completely adjustable without adjusting the system clock. Each pixel on the sensor is individually
addressable allowing the user to control “Window of Interest” (WOI) panning and zooming. Control of sub-sam-
pling, resolution, exposure, gain, and other image processing features is accomplished via a two pin I
The sensor is run by supplying a single Master Clock. The sensor output is 10 digital bits providing wide dynamic
range images.
