The LM9830 is a complete document scanner system on a single IC. The LM9830 provides all the functions (CCD control, illumination control, analog front end, pixel processing function image data buffer/SRAM controller, microstepping motor controller, and EPP parallel port interface) necessary to create a high performance color scanner. The LM9830 scans images in 36 bit color, and has output data formats for 36 bits, 30 bits, and 24 bits.
