Data Sheet
1.0 General Description
The AMIS-710200 (PI200MC-A4) is a contact image sensor (CIS) module. It is a long CIS using MOS image sensor technology for
high-speed performance and high sensitivity. The AMIS-710200 is suitable for scanning A4 size (216mm) documents with 8 dots per
millimeter (dpm) resolution. Applications include document scanners, mark readers and other office automation equipment.
2.0 Key Features
Light source, lens and sensor are integrated into a single module
8dpm resolution, 216mm scanning length
437µsec/line scanning speed @ 4.0MHz clock rate
Wide dynamic range
Analog output
660 Red LED light source
Compact size - 20.5mm x 21.5mm x 232mm
Low power
Light weight
3.0 Functional Description
The AMIS-710200 imaging array consists of 27 sensors, AMIS-720220 (PI3020), produced by AMIS. The sensor is a monolithic chip
with an array of 64 photo sensing elements, of which 27 are cascaded to provide 1728 photo-detectors. These cascaded chips are
contiguously aligned in a single row and bonded to the printed circuit board (PCB). See Figure 1, AMIS-710200's block diagram. This
configuration allows a stream of sequential video pixels to be read from its output port, for example, starting from the first pixel, 1st,
located next to the connector end of the module and continues to and through the last pixel, 1728th. Each chip contains a complete

readout. Additionally, the chips contain a chip selection switch that is interrogated in a sequence as each predecessor chip completes
its scanning process.

Figure 1: AMIS-710200 Block Diagram
Figure 2 shows a mechanical cross section of the module's internal structure. Mounted in the module is a number of components.
These components function together to provide the module a complete integrated system. The LED light bar illuminates the documents
through the window and reflection from the imaged documents is picked up and focused by the one-to-one graded indexed micro lens
array.
The lens, through the glass window, focuses the scanned images from the document onto the sensing plane of the sensor chips, which
is mounted on the PCB. During the imaging process, the document is passed across the glass window's surface.
wwTwh.eDaPtCaSBheneott4Uon.clyomhas the sensor chips mounted on it, but it has an on-board amplifier, a clock buffer for both the start pulse (SP), and
the module's master clock (CP) buffer. This amplifier processes the pixel charges from the image sensor chips and converts them into
voltage signal to produce a sequential stream of video at the output pin of the AMIS-710200 module.
All these discussed components are housed in a small plastic housing which has a cover glass, the window. This housing with its
sealed windows protects the imaging array, the micro lens assembly and the LED light source from dust.
