Data Sheet

1.0 General Description

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.

2.0 Key Features

• Light source, lens and sensor are integrated into a single module

• 8dpm resolution, 104mm scanning length

• High speed page scan - up to 167µsec/line @ 5MHz pixel rate

• Wide dynamic range

• Analog output

• Two color LED light source: yellow-green (YG) and red

• Compact size ≅ 14mm x 19mm x 120mm

• Light weight

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).
