300DPI CIS Sensor Chip
Engineering Data Sheet
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.

a 50% duty cycle the operator has additional timing flexibility if it desired.
