CHAPTER 1 GERERAL DESCRIPTION
Genesys Logic's single-chip GL842 (GeneScanTM 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, GL842 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 GL842 include five motor acceleration/ deceleration curve tables for high speed motor moving.

CHAPTER 2 FEATURES
Highly integrated scanner controller chip. (2-in-1; Scanner Controller and USB 2.0 Interface) USB 2.0 High Speed (480Mbit) compliance. (USB 2.0 High Speed logo certified) Design for sheetfed, flatbed and transparency scanner. 12MHz Low frequency clock input required for better EMI. Flexible 3.3V/5V power selection for pad I/O. Adjustable working speed for different usage. Fast operation speed. (0.3us/pixel. in 40MHz working clock) It costs only 12 seconds for 600dpi A4 size color scanning. Available sensor types: 600, 1200 and 2400dpi color CIS or CCD. Support linear or stagger CCD, such as NEC, Toshiba or Sony CDD. Support 48-Bits color (16-Bits gray level) scanning. Support color, fine Gray, fast gray and fast B/W scan for CDD. Support color, gray, true gray and B/W scan for CIS.
Support three scanning types: pixel by pixel (pixel rate), line by line (line rate) and RGB line by turns (line rate).
16 bits white/dark shading and 16-to-8 bits Gamma correction. Support digital average and hardware deletion pixel function for speeding up low resolution scan. Support hardware deletion type for DPI function (2400 to 1 DPI, 1 DPI decrement). Programmable threshold level for B/W. Exposure time is adjustable (1 pixel time increment step). Scan width (scan area) control for horizontal line (1 pixel increment step). Support 256K*16, 256K*16*2 and 1M*16 bits EDO-DRAM. Support 5 acceleration/deceleration motor tables for detailed controllable high speed motor moving. Support controllable bipolar motor in full, half and quarter steps moving. Support controllable uni-polar motor in full and half steps moving. Build-in PWM control phase for uni-polar motor. Programmable dummy lines to resolve start/stop (discontinuous) problem. Watch dog protect for lamp, motor and ASIC. Lamp timeout (sleeping) control. Support 16 GPIO pins and 2 GPO pins. Output motor trigger signal under scanning for ADF. 2 Output ports for lamp (include flatbed and transparency with PWM) control. Input port for home sensor. Power on check status. Support LED Blinking. Support Back Scanning.
