CS9211-VNG

Product Summary

The CS9211-VNG is a Geode. CS9211 Graphics Companion Flat Panel Display Controller which suitable for systems that use any GX-series processor (e.g., GX1, GXLV, GXm) along with the CS5530A I/O companion, also members of the Geode family of products. The CS9211-VNG converts the digital pixel stream output of the CS5530A to the digital RGB inputs used by standard single and dual-scan STN LCD display panels. Support is provided for both color and monochrome dual-scan STN (DSTN) flat panels up to 1024x768 resolution, and for color single-scan panels up to 640x480 resolution.

Parametrics

CS9211-VNG absolute maximum ratings: (1)Operating Case Temperature: 130℃; (2)Storage Temperature: -40 to 150℃; (3)Supply Voltage: 4.0 V.
