Description:

Peripheral Imaging Corporation PI3012A CIS sensor chip is a 300 dot per inch resolution linear array image sensor chip which utilizes PIC’s proprietary CMOS Image Sensing Technology. This image sensor is to be used for butting end-to-end on a printed circuit board (PCB) using chip-on-board technology to form a scanning array with various lengths. Applications for the sensor array are facsimile, scanner, check reader, and office automation equipment.

Figure 1 is a block diagram of the sensor chip. Each sensor chip consists of 96 detector elements, their associated multiplexing switches, buffers, and a chip selector. The detector element-to-element spacing is approximately 84.6 μm. The size of each chip without scribe lines is 8080 μm by 380 μm. Each sensor chip has 6 bonding pads. The pad symbols and functions are described in Table 1.
