Description
PAS202BCB 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.
