General Description
The PI404MC-A8 is a CIS module. It is a long contact image chips, using MOS image
sensor technology for high-speed performance and high sensitivity. The PI404MC-A8 is
suitable for scanning A8 size (57 mm) documents with 15.7 dots per millimeter resolution.
Applications include document scanning, mark readers, gaming and office automation
equipment.
Functional Description
The PI404MC-A8 imaging array consists of 7 sensors that are cascaded to provide 896
photo-detectors with their associated multiplex switches, and a digital shift register that
controls its sequential readout. Mounted in the module is one-to-one graded indexed
micro lens array that focuses the scanned documents to image onto its sensing plane.
