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. 2.0 Key Features • • • • • • • • • Low power-single power supply at 5.0V 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). Figure 1: AMIS-710256-A6 Module Block Diagram AMI Semiconductor – Aug. 2006, M-20607-001 www.amis.com 1 AMIS-710256-A6: 200dpi CIS Module 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 the 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-710256-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 JAE 1L-Z-10P-S125T3-E. Its I/O designation is provided in Table 1. The location of Pin 1 is indicated on the module outline.
