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.
