LM9702SL Datasheet | National Semiconductor

Description The LM9702 contains all functions needed to build a VGA digital still and/or video camera. It incorporates a 16 bit RISC microprocessor, a flexible image processing pipeline, hardware JPEG pression, and the required periphery modules in a single IC. This architecture allows a very fast click-to-click time and full resolution video without sacrificing image quality or cost; because the putation extensive operations are processed by circuitry dedicated to image processing. The highly optimized memory management provided by the LM9702 keeps the memory cost of the plete camera to a minimum. A chip set prising of the LM9702 and a National VGA CMOS image sensor plemented by a lens, battery, pact flash, power management for the battery, and LCD (optional) yields a plete high performance cost effective digital still and/or video camera.
