| AMIS-710201: 200dpi CIS Module Data Sheet 1.0 General Description The AMIS-710201 (PI201M-A4) is a contact image sensor (CIS) module using MOS image sensor technology for high-speed performance and high sensitivity. The AMIS-710201 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 1.72ms/line scanning speed Wide dynamic range analog output Yellow-Green light source Compact size - 13.5mm x 18mm x 232mm Low power Light weight 3.0 Functional Description The AMIS-710201 imaging array consists of 27 sensors 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-710201 module. Figure 1: AMIS-710201 Cross Section AMI Semiconductor - May 06, M-20539-001 www.amis.com 1 AMIS-710201: 200dpi CIS Module Data Sheet Illumination is by means of an integrated LED light source. All components are housed in a small plastic housing which has a cover glass which 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-710201 is shown in Figure 1 and the block diagram in Figure 2.
