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

I2C

offset correction DAC and programmable gain control.
