PAS202BBB
PAS202BCB SINGLE-CHIP CMOS VGA COLOR DIGITAL IMAGE SENSOR
PAS202BBB SINGLE-CHIP CMOS VGA B&W DIGITAL IMAGE SENSOR
General Description
The PAS202BCB/PAS202BBB is a highly integrated CMOS active-pixel image sensor that has a VGA resolution
of 644H x 484V. To have an excellent image quality, the PAS202BCB/PAS202BBB outputs 10-bit RGB raw data
through a parallel data bus. It is available in color or monochrome and in 28-pin LCC.
The PAS202BCB/PAS202BBB can be programmed to set the exposure time for different luminance condition via
I2CTM serial control bus. By programming the internal register sets, it performs on-chip frame rate adjustment,
offset correction DAC and programmable gain control.
