AMIS-710254-A6: 200dpi CIS Module
Data Sheet
1.0 General Description
The AMIS-710254-A6 (PI254MC-A6-R) is a contact imaging sensor (CIS) module. It operates from a single 5V supply. The module
contains of 13 image sensor chips (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. Like its predecessor, the AMIS-710254-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-710254-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 so that each following chip is 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 only change from its predecessor module is in
this amplifier. It was slightly altered to gain the single supply feature through the application of the new rail-to-rail single volt operational
amplifiers (see Figure 1).

Data Sheet
The PCB containing the imaging array is enclosed in a module housing along with a one-to-one graded indexed micro lens array, which
focuses image of the scanned documents onto the sensing line of the sensor chips. The document is illuminated with an LED light
source, which is also mounted in the housing (see Figure 2).
Figure 2: AMIS-710254-A6 Cross Sectional View
This pictorial cross section shows the LED bar light source and its illumination path. The light on the document reflects images of the
document. The reflected images focus through the micro lens onto the image sensing line of the chips, where images are converted to
proportional electrical charges. An on board amplifier processes these signal charges into proportional video signal voltages, which are
sent out to the output video port.
All components are housed in a small plastic housing and covered with a glass window. This cover glass not only serves to protect all
of the critical components within the housing from dust, but along with the micro lens, it plays a minor role in the depth-of-focus because
it lies in the optical path.
4.0 Pin Out Description
There is one connector located at the end of the module. The outline of the module's housing in Figure 4 illustrates the connector
location. With the module window facing down on the flat surface, the viewer looking down on backside of the module and the
connector's pins facing the viewer, the connector is located on the right-hand end of the module. The connector is a single row of ten
pins with a 1.25mm pin space. It is a ECE EBW-PK23-P010L2-3Z. Its I/O designation is provided in Table 1. The location of Pin 1 is
indicated on the module outline.

See Note 7 for MTF & DOF
Tint: line scanning rate or integration time. Tint is determined by the interval of two start pulses (SP).
Fclk: main clock frequency applied to into the module. It is also equal to the pixel frequency.
Vpavg = ∑ Vp(n)/832; where Vp(n) is the nth pixel voltage value
Up is defined as follows: Upmax= [(Vpmax - Vpavg) / Vpavg] x 100% and Upmin= [(Vpavg - Vpmin) / Vpavg] x 100%; where Upmax is determined by the highest
nth video pixel, Vp(n), and Vpmin is determined by minimum pixel, Vp(n), then Up is selected from the largest of the two values |Upmax| or |Upmin|.
Upadj is between two adjacent pixel's non-uniformity and defined as follows:
Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%
Ud = Vdmax – Vdmin
Vdmin is the minimum output in the dark
Vdmax is the maximum output voltage in the light
MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]. Depth of focus ( DOF), range is defined with the MTF. MTF is measured at the glass surface to approximately
0.4mm from the glass surface, and is > 40% with its peaks at approximately the mid-point, 0.2mm.
Vmax: maximum output voltage at 50lp/inch (at 1/2 of the optical Nyquest frequency)
Vmin: minimum output voltage at 50lp/inch
lp / inch: line pair per inch
