W82C485

The W82C485 device is a kind of 16-bit CMOS color paletters which many be used in VGA,superVGA,XGA or TARGA compatible video display adapters.When used in IBM XGA video display adapters,the 16-bit XGA color format data is displayed with a full 64K simulataneous colors.In the 16-bit XGA data format,5 bits are allocated for the red color,6 bits for green, and 5 bits for blue,while TARGA allocates 5-5-5,respectively.With the W82C85 high color paletters,low-cost VGA/SVGA/Macintosh graphics boards can be designed that provide high resolution color displays for applications like microsoft windows,color pre-press.Desktop publishing, image processing, and multimedia.With aimost"true color"quality at low cost.

W82C485 has many unique features: The first one is 16-bit XGA format for 64K on-screen colors.The second one is 15-bit TARGA format for 32K on-screen colors.The third one is power-down mode.The forth one is functionally compatible with 11C485.
