Micron MT9V022 Automotive CMOS Image Sensor
Chipworks released a report last week about the Micron MT9V022 Automotive CMOS Image Sensor. The Micron MT9V022 is a CMOS image sensor designed exclusively for the automotive environment. Recently, Micron was awarded a patent related to the MT9V022 pixel architecture.
The MT9V022 uses an unusual five-transistor (5T) pixel architecture, in which each pixel has a separate pixel reset transistor (T2) connected directly to the pixel photocathode. The MT9V022 boasts a 100dB+ dynamic range. This enables the sensor to capture scenes containing both low light levels (down to sub-0.1 lux) and direct sunlight.
Pixel Size: 6µm x 6µm
Array Format (active): 752H x 480V
Imaging Area: 4.55mm x 2.97mm
Color Filter Array: Monochrome or RGB Bayer
Optical Format: 1/3 inch
