E-mail: fae_service@pixart.com.tw V1.2, May. 2002 PAS202BCA SINGLE-CHIP CMOS VGA COLOR DIGITAL IMAGE SENSOR PAS202BBA SINGLE-CHIP CMOS VGA B&W DIGITAL IMAGE SENSOR General Description The PAS202BCA/PAS202BBA 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 PAS202BCA/PAS202BBA outputs 10-bit RGB raw data through a parallel data bus. It is available in color or monochrome and in 323-pin LCC. The PAS202BCA/PAS202BBA can be programmed to set the exposure time for different luminance condition via I2C TM serial control bus. By programming the internal register sets, it performs on-chip frame rate adjustment, offset correction DAC and programmable gain control.
