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.
