CS9211 - Geode Graphics Companion Flat Panel Display Controller [Obsolete]
Datasheet Obsolete Versions Knowledge Base

Features
•Supports most SVGA DSTN panels and the VESA FPDI (Flat Panel Display Interface) Revision 1.0 Specification.
•Directly interfaces to panels; no external drivers needed (excluding backlight inverter).
•Supports 18-bit color pixel input data stream in 6:6:6 format, for a maximum display of 262,144 colors.
•Supports up to 65 MHz pixel clock (DOTCLK).
•Supports resolutions up to 1024x768 pixels.
•Fast display refresh rate, up to 120 Hz for DSTN panels, achieved by writing both panel halves simultaneously.
•16- or 24-bit dual-scan color STN (DSTN) support.
•8- or 16-bit dual-scan monochrome STN (DSTN) support.
•8-bit single-scan color STN (SSTN) panel support.
•TFT panel support provided via pass-through mode.
•9-, 12- or 18-bit TFT support.
•9+9 or 12+12-bit, 2 pixels per clock TFT panel support.
•Frame rate modulation (FRM) allows up to 32 shades of gray (intensities) for each primary color (R,G,B) with no loss of spatial resolution.
•Proprietary dithering algorithm allows display of additional colors for a maximum of 262,144 colors.
•Programmable control of input and output sync pulse widths, delays, and polarities allows interfaces to many panel types.
•Programmable panel power sequence controls.
•Built-in memory controller supports either SDRAM or EDO memory for the DSTN frame buffer.
•Configuration via a serial programming interface.
•Low-power, 3.3V operation.
•144-pin LQFP (Low-profile Quad Flat Pack).

 

General Description

The National Semiconductor® Geode™ CS9211 graphics companion is 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 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. More...

General Description

The National Semiconductor® Geode™ CS9211 graphics companion is 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 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.

The typical system connection shows how to connect the CS9211 with other system components. Note that the external frame buffer is only required for DSTN panels.
