LC82221L

Ordering number : EN *5846 CMOS IC LC82221L Motion JPEG Decoder Preliminary Overview The LC82221L is a full-color digital image data expansion IC that accepts data in formats that essentially conform to the JPEG standard. With the provision of frame memory, this IC can input and output image data in standard video formats. In addition, it also supports a wide range of image display functions using that frame memory. As compared to earlier JPEG ICs, this IC features simplified JPEG functionality and a greater emphasis on display functions. Thus it supports the creation of excellent costperformance ratio systems for applications that require a display system. Users can select either RGB or YUV for image data output. Built-in YUV to RGB color conversion circuit The LC82221L supports image sizes up to 1024 pixels in the horizontal direction. The range of vertical sizes handled can be set up arbitrarily, since it is limited by the size of the DRAM provided. 3.3-V single-voltage power supply. Low power. The display position and display size can be set. SOI and EOI marker support Horizontal and vertical scrolling display functions Support for overwrite display, in which the next data for expansion is displayed by overwriting the previously expanded image data Features High image quality image expansion using the JPEG system Superlative cost performance achieved by only providing decoding functions. Two built-in quantization tables. High-speed processing ac...
