GL128中文资料High Speed USB 2.0 2-in-1 Scanner Controller数据手册Genesys规格书

描述 Description

Genesys Logic's single-chip GL128 is a high speed, high performance, low cost and rich scalability controller for self-powered scanner. It successfully integrates scanner function ASIC and USB 2.0 interface controller into one single-chip. With its high performance design architecture, GL128 is not only ready for supporting CIS or CCD image sensors (600, 1200, 2400, 3200, 3600, 4800 and 9600dpi resolution) that are used in flatbed, transparency , but is able to co-work with unipolar or bipolar stepping motors. Advanced features of GL128 include five motor acceleration/ deceleration curve tables for high speed motor moving.
