AMIS-710324-A4: 300dpi CIS Module Data Sheet 1.0 General Description The AMIS-710324-A4 (PI324MC-A4) is a contact image sensor (CIS) module. It is a dual-analog-output contact image sensor, using MOS image sensor technology for high-speed performance and high sensitivity. The AMIS-710324-A4 is suitable for scanning A4 size (216mm) documents with 11.8 dots per millimeter (dpm) resolution. Applications include fax machines, game systems, a variety of mark readers and other automation equipment requiring document scanners. 2.0 Key Features • • • • • • • • • Light source, lens and sensor are integrated into a single module 11.8dpm resolution, 216mm total scanning length (2592 pixels long) Two independent analog outputs (split into two sections of 1248 pixels and 1344 pixels) Up to 270µsec/line scanning speed with red light source Wide dynamic range Red LED light source Compact size ≅ 14mm x 19mm x 232mm Low power Light weight 3.0 Functional Description The AMIS-710324-A4 imaging array consists of 27 sensors, AMIS-720321 (PI3021), produced by AMI Semiconductor. The sensor is a monolithic chip with an array of 96 photo sensing elements, of which 27 are cascaded to provide 2592 photo-detectors. Additionally, these chips give the users the readout flexibility in selecting their desired data format. These cascaded chips are segregated into two electrically independent sections of 13 chips and 14 chips, but they are still contiguously aligned in a single row, see Figure 1 (the module's block diagram). This configuration lends itself to a positional stream of video pixels, whether they are read in parallel or sequentially from the two output ports. Each chip contains a set of multiplex switches, and a digital shift register to control the chips sequential readout. Additionally, the chips contain a chip selection switch that is interrogated in a sequence as each predecessor chip completes its scanning process. Since this module has two output ports from two independently controlled sections of chips, the users are required to enter a set of control clocks and power into each section through the two provided connectors located on each end of the module. AMI Semiconductor – Jun. 06, M-20564-001 www.amis.com 1 AMIS-710324-A4: 300dpi CIS Module Data Sheet Figure 1: AMIS-710324-A4 Module Block Diagram (See Table 1 for Pin Out Designation) Figure 2 depicts a cross sectional pictorial of the module. Mounted in the module is a one-to-one graded indexed micro lens array that focuses the scanned documents' image onto the chip's sensing line. The sensing line is located along the module's sensor axis, known as the read line. These photon images are transformed into proportional video charges and processed by two on-board amplifiers. The video signal from the amplifier transmits a sequential stream of video pixels to the video output pin of the AMIS-710324-A4 module. Also mounted in the housing is a LED light source. Figure 2 shows the LED bar and its illumination path. The path traces the ray from the LED and is reflected from the document and focused through the ROD lens and onto the sensors. All these components are housed in a small plastic housing with a cover glass. The cover glass serves as a window with the outside surface as the focal point for the image on the document. It also serves to protect the imaging array, the micro lens assembly and the LED light source from dust.

The outline of the module in Figure 5 of the mechanical section illustrates these connector locations. With the module window facing down on a flat surface and with the viewer looking down on the backside of the module, the connectors are located on each end of the module with their pins pointing toward the viewer. The connectors for Section 1 have 12 pins and are located on the right-hand side. The part number is JAE IL-Z-12P-S125L3-E. Its pin numbers and designations are listed in Table 1.
