General Description
The PI240MC-A4 is a contact imaging sensor, CIS, module, which is composed of 1728
PI3020 sensor chips. The PI3020 is a 200 DPI solid-state line imaging array, also a product of
Peripheral Imaging Corporation. This imaging device is fabricated using MOS imaging sensor
technology for high-speed performance and high sensitivity. The PI240MC-A4 is suitable for
scanning A4 size (216 mm) documents with 8 dots per millimeter resolution. Applications
include variety of document scanners, variety of mark readers, and other automation
equipment.
Functional Description
The PI240MC-A4 imaging array consists of 27 chips that are cascaded to provide 1728 photo-
detectors with their associated multiplex
switches, and a digital shift register that
