AMIS-710256-A6:
200dpi CIS Module
1.0 General Description
Data Sheet
The AMIS-710256-A6 (PI256MC-A6-R) is a two-color contact imaging sensor (CIS) module. The module can operate from a single 5V
supply. It has two +5V inputs. One supply is for both LED light sources and the other is for the module’s circuit. The module contains 13
sequentially cascaded AMIS-720233 (PI3033) sensor chips. The AMIS-720233 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 its high-speed
performance and high sensitivity. The AMIS-710256-A6 is suitable for scanning A6 size (104mm) documents with eight 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-710256-A6 consists of 13 imaging array sensors, which are cascaded to provide 832 photo-detectors. Each sensor contains
its associated multiplex switches and a digital shift register, which controls its sequential readout. Each sensor also contains a chip
select switch. The chip select switches are accessed sequentially as its predecessor chip completes its scan. These chips are mounted
on a printed circuit board (PCB) along with clock buffers and a video signal amplifier. The AMIS-710256-A6 module is the single supply
with two color LED features (see Figure 1).
