General Description
The Micron^® Imaging MT9V012 is an oversize VGA-
format CMOS active-pixel digital image sensor with a
pixel array of 649H x 489V. It incorporates sophisti-
cated on-chip camera functions such as windowing,
mirroring, column and row skip modes, and snapshot
mode. It is programmable through a simple two-wire
serial interface and has very low power consumption.
The VGA CMOS image sensor features DigitalClarity—
Micron’s breakthrough low-noise CMOS imaging tech-
nology that achieves CCD image quality (based on sig-
nal-to-noise ratio and low-light sensitivity) while
maintaining the inherent size, cost, and integration
advantages of CMOS.

When operated in its default mode, the sensor gener-
ates a VGA image at 30 frames per second (fps). An on-
chip analog-to-digital converter (ADC) generates a 10-
bit value for each pixel. The pixel data is output on a
10-bit output bus and qualified by an output data
clock (PIXCLK), together with LINE_VALID and
FRAME_VALID signals. A FLASH output strobe is pro-
vided to allow an external Xenon or LED light source to
synchronize with the sensor exposure time. The sensor
can be programmed by the user to control the frame
size, exposure, gain setting and other parameters.
