AMIS-720341-A: Contact Image Sensor

Data Sheet

1.0 Description

AMI Semiconductor’s AMIS-720341-A (PI3041A) contact image sensor (CIS) chip is a 300 dots per inch (dpi) resolution, linear array

image sensor chip. The sensor chip is processed using a CMOS image sensing technology and it belongs to the Image Sensor Product

Line (ISPL) group within AMIS. Designed for cascading multiple chips in a series, the image sensor chips use a chip-on-board process.

They are bonded end-to-end on a printed circuit board (PCB). This bonding process allows the CIS module manufacturers to produce

variable CIS module lengths in increments of the chip array lengths. Hence, the modules are easily applied in a large number of

document scanners found in today’s facsimile market. Some examples of these large document scanners are those that produce wide

format maps and architectural drawings, down to the narrow width scanners, such as those found in check readers, lotto tickets,

entrance gates tickets, etc. This is not to exclude office automation equipment, which requires an even more variety in scanning widths,

as well as those with special mechanically configurations.

Figure 1 is a block diagram of the imaging sensor chip. Each sensor chip consists of 96 detector elements, their associated

multiplexing switches, buffers, and a chip selector. The detector's element-to-element spacing is approximately 83.3µm. The size of

each chip without scribe lines is 8080µm by 380µm. Each sensor chip has seven bonding pads. The pad symbols and functions are

described in Table 1.
