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. Figure 1: AMIS-710240 Cross Section AMI Semiconductor –May 06, M-20546-001 www.amis.com 1 AMIS-710240: 200dpi CIS 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.

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.
