Description:

Peripheral Imaging Corporation PI3034A CIS sensor chip is a 200 dot per inch resolution linear array image sensor chip, which uses PIC’s proprietary CMOS Image Sensing Technology. This image sensor’s intended applications are to fabricate Contact Image Sensor, CIS modules with various lengths. This is accomplished by mounting them on a printed circuit board (PCB) through an end-to-end butting process. This process is generally referred to as the chip-on-board technology. Its typical circuit implementation in an A4 size 1728 elements CIS module is shown in a schematic diagram on page 6. The schematic demonstrates its operational implementation and interfacing circuits. They are used in facsimile, scanner, check reader, and office automation equipment.

Figure 1 is a block diagram of the sensor chip. Each sensor chip consists of 64 detector elements, their associated multiplexing switches, buffers, and a chip selector. The detector element-to-element spacing is approximately 125 um. The size of each chip without scribe lines is 7950 um by 290 um. Each sensor chip has 6 bonding pads. The pad symbols and functions are described in Table 1.
