200DPI CIS Sensor Chip
Engineering Data Sheet
Description:
Peripheral Imaging Corporation PI3033B CIS, Contact Image Sensor, chip is a 200 dot per
inch resolution, linear array image sensor chip. The sensor chip is processed with PIC’s
proprietary CMOS Image Sensing Technology. Designed for cascading multiple chips in a
series, the image sensor chips, using chip-on-board process, are bonded end-to-end on a
printed circuit board (PCB) in varying sensing array lengths. Accordingly offering image
reading widths to suit document scanners found in facsimile, scanner, check reader, and office
automation equipment.
Figure 1 is a block diagram of the imaging sensor chip. Each sensor chip consists of 64 detector
elements, their associated multiplexing switches, buffers, and a chip selector. The detector's element-
to-element spacing is approximately 125 um. The size of each chip without scribe lines is 7950 um by
500 um. Each sensor chip has 8 bonding pads. Only 7 are used to make the CIS Modules. The pad
symbols and functions are described in Table 1.
