AMIS-710325-A4: 300dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710325-A4 (PI325MC-A4) is a contact image sensor (CIS) module which uses MOS image sensor technology for high-speed
performance and high sensitivity. The AMIS-710325-A4 is suitable for scanning A4 size (216mm) documents with 11.8 dots per
millimeter (dpm) resolution. Applications include fax machines, game systems, a variety of mark readers and other automation
equipment requiring document scanners.

3.0 Functional Description
The AMIS-710325-A4 imaging array consists of 27 sensors, AMIS-720321 (PI3021), produced by AMI Semiconductor, are cascaded to
provide 2592 photo-detectors with their associated multiplex switches and a digital shift register, controls its sequential readout.
Mounted in the module is a one-to-one graded indexed micro lens array, 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-
710325-A4 module.
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, 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. The cross section of the AMIS-
710325-A4 is shown in Figure 1 and the block diagram in Figure 2.
