AMIS-710240: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710240 (PI240MC-A4) is a contact imaging sensor (CIS) module composed of 1728 AMIS-720033 (PI3020) sensor chips.
The AMIS-720033 is a 200 dots per inch (dpi) solid-state line imaging array, also a product of AMI Semiconductor. This imaging device
is fabricated using MOS imaging sensor technology for high-speed performance and high sensitivity. The AMIS-710240 is suitable for
scanning A4 size (21mm) documents with 8 dots per millimeter (dpm) resolution. Applications include variety of document scanners,
variety of mark readers and other automation equipment.
2.0 Key Features
Inverted video signals (magnitude increases in a negative direction)
Light source, lens and sensor are integrated into a single module
8dpm resolution
216mm scanning length
0.347ms/line scanning speed, operated @ 5.0MHz
Wide dynamic range analog output
660nm light source
Compact size: 14mm 19.5mm x 232mm
Low power
Light weight
3.0 Functional Description
The AMIS-710240 imaging array consists of 27 chips that are cascaded to provide 1728 photo-detectors with their associated multiplex
switches and a digital shift register that controls its sequential readout. Mounted in the module is a one-to-one graded indexed micro
lens array that focuses the scanned documents to image onto its sensing plane. The on-board amplifier processes the video signal to
produce a sequential stream of video at the video output pin of the AMIS-710240 module.

Data Sheet
Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing which
has a cover glass that acts as the focal point for the object being scanned and protects the imaging array, micro lens assembly and
LED light source from dust. I/O to the module is the 10-pin connector located on one end of the module. See Figure 4. The cross
section of the AMIS-710240 is shown in Figure 1 and the block diagram in Figure 2.

Note:
1. Tint is determined by the time interval between two SP. The longest integration time is determined by the degree of leakage current degradation that can be
tolerated by the system. A 10ms maximum is a typical rule-of-thumb, thus the experienced CIS user can use his discretion in determining the integration time.
