AMIS-710317-A6: 300dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710317-A6 (PI317MC-A6) is a contact imaging sensor (CIS) module, which is composed of 13 AMIS-720321 (PI3021)
sensor chips. The AMIS-720321 is a 300 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-
710317-A6 is suitable for scanning A6 size (104mm) documents with 11.8 dots per millimeter (dpm) resolution. Applications include
ticket, check and card scanners, a variety of mark readers and other automation equipment.

3.0 Functional Description
The AMIS-710317-A6 imaging array consists of 13 sensors that are cascaded to provide 1248 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-710317-A6 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 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. The cross section of the
AMIS-710317-A6 is shown in Figure 1 and the block diagram in Figure 2.
