The Micron Imaging MT9V112I2ASTC is a VGA-format, single-chip camera CMOS active-pixel digital image sensor. This device combines the MT9V012 image sensor core with fourth-generation digital image flow processor technology from Micron Imaging. MT9V112I2ASTC captures high-quality color images at VGA resolution.

The VGA CMOS image sensor MT9V112I2ASTC features DigitalClarity -Micron's breakthrough low-noise CMOS imaging technology that achieves CCD image quality (based on signal-to-noise ratio and low-light sensitivity) while maintaining the inherent size, cost, and integration advantages of CMOS. The sensor MT9V112I2ASTC is a complete camera-on-a-chip solution designed specifically to meet the low-power, lowcost demands of battery-powered products such as cellular phones, PDAs, and toys. MT9V112I2ASTC incorporates sophisticated camera functions on-chip and is programmable through a simple two-wire serial interface.

The MT9V112I2ASTC performs sophisticated processing functions including color recovery, color correction, sharpening, programmable gamma correction, auto black reference clamping, auto exposure, automatic 50Hz/60Hz flicker avoidance, lens shading correction, auto white balance (AWB), and on-the-fly defect identification and correction. Additional features of MT9V112I2ASTC include day/night mode configurations; special camera effects such as sepia tone and solarization; and interpolation to arbitrary image size with continuous filtered zoom and pan. The MT9V112I2ASTC supports both Xenon and LEDtype flash light sources in several snapshot modes.

The MT9V112I2ASTC can be programmed to output progressive- scan images up to 30 frames per second (fps).

The image data can be output in any one of six 8-bit formats:
• ITU-R BT.656 (formerly CCIR656, progressive scan only) YCbCr
• 565RGB
• 555RGB
• 444RGB
• Raw Bayer
• Processed Bayer

The FRAME_VALID and LINE_VALID signals of MT9V112I2ASTC are output on dedicated balls, along with a pixel clock that is synchronous with valid data.
