AMIS-710200:200dpi CIS Module
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
control circuitry. Integrated within monolithic chip is a set of multiplex switches, and a digital shift register to control the chips sequential
readout. Additionally, the chips contain a chip selection switch that is interrogated in a sequence as each predecessor chip completes
its scanning process.
