AMIS-720442-A: 400dpi Contact Image Sensor
Data Sheet
1.0 Description
AMI Semiconductor’s AMIS-720442-A (PI3042A) contact image sensor (CIS) is a 400 dots per inch (dpi) linear array image sensor
chip. The sensor chip is processed using a CMOS image sensing technology, belonging to AMIS. Designed for cascading multiple
chips in a series, the image sensor chips, using chip-on-board process, are bonded end-to-end on a printed circuit board (PCB). This
bonding process allows the manufacturers to produce variable CIS module lengths in increments of chip array lengths. This allows a
wide variety of image reading widths which are easily applied to the numerous document scanners found in facsimile, as well as the
narrow width scanners, such as, those found in check reader, lotto tickets, entrance gates tickets, etc. Included in this list of scanners
are various types of automated office equipment which require a wide variety of scanning widths.
Figure 1 is a block diagram of the imaging sensor chip. Each sensor chip consists of 128 detector elements, their associated
multiplexing switches, buffers and a chip selector. The detector's element-to-element spacing is approximately 62.5μm. The size of
each chip without scribe lines is 8080μm by 385μm. Each sensor chip has seven bonding pads. The pad symbols and functions are
described in Table 1.
