LM9831 is a single-chip USB image scanner system that provides all the functions (image sensor control, illumination control, analog front end, pixel processing function image data buffer/DRAM controller, microstepping motor controller, and USB interface) required to create a high-performance color scanner. The LM9831 scans images in 42-bit color/14-bit grayscale and has output data formats for 24-bit color/8-bit grayscale. The LM9831 supports sensors with pixel counts of up to 16384 pixels x 3 colors (1200 dpi x 13.6 inches). The LM9831's low operating and suspend mode supply currents allow design of USB bus-powered scanners. The only additional active components required are an external 4Mbit or 16Mbit DRAM for data buffering and power transistors for the stepper motor.
