GENERAL DESCRIPTION
Genesys Logic's single-chip GL841 (GeneScan series) is a high speed, high
performance, low cost and rich scalability controller for scanner. It successfully
integrates scanner function ASIC and USB 2.0 interface controller into one
single-chip. With its high performance design architecture, GL841 is not only
ready for supporting CIS or CCD image sensors (600dpi,1200dpi or 2400dpi
resolution) that are used in flatbed or transparency scanners, but is able to co-
work with uni-polar or bi-polar stepping motors. Advanced features of GL841
include five motor acceleration/ deceleration curve tables for high speed motor
moving.
