GeodeTM CS9210 Graphics Companion
DSTN Controller
General Description
The CS9210 graphics companion is suitable for systems
that use either the GXLV or GXm processor along with the
CS5530 I/O companion; all members of the National
Semiconductor
®
GeodeTM
family
of
products.
The
CS9210 converts the digital RGB output stream to the dig-
ital graphics input stream required by most industry stan-
dard DSTN color flat panel LCDs. It can drive all standard
DSTN flat panels up to a 1024x768 resolution. The sys-
tem connection example shows how the CS9210 inter-
faces with the rest of the system components.
Features
18-bit color support for digital pixel input
65 MHz pixel clock operation supports up to 1024x768
panels
Simultaneous CRT and DSTN display with up to 75 Hz
refresh rate
2X display refresh modes, up to 120 Hz
Supports most SVGA DSTN panels and the VESA
FPDI (Flat Panel Display Interface) Revision 1.0
Specification

allows a pass-through mode for the digital pixel input
Programmable frame rate modulation (FRM), up to 32
levels
Programmable dither, up to 16 levels
Supports EDO memory, 16-bit interface
Configuration via a serial programming interface
Low-power, 3.3V operation

Signal Definitions
This section defines the signals and external interface of
the Geode CS9210. Figure 2-1 shows the pins organized
by their functional groupings (internal test and electrical
pins are not shown).
2.1
PIN ASSIGNMENTS
The tables in this section use several common abbrevia-
tions. Table 2-1 lists the mnemonics and their meanings.
Figure 2-2 shows the pin assignment for the CS9210 with
Tables 2-2 and 2-3 listing the pin assignments sorted by
pin number and alphabetically by signal name, respec-
tively.
In Section 2.2 "Signal Descriptions" a description of each
signal within its associated functional group is provided.

Mnemonic
Definition
I
Standard input pin.
I/O
Bidirectional pin.
O
Totem-pole output.
OD
Open-drain output structure that
allows multiple devices to share the
pin in a wired-OR configuration
PU
Pull-up resistor
PD
Pull-down resistor
smt
Schmitt Trigger
t/s
Tri-state signal
VDD (PWR)
Power pin.
VSS (GND)
Ground pin
#
The "#" symbol at the end of a signal
name indicates that the active or
asserted state occurs when the signal
is at a low voltage level. When "#" is
not present after the signal name, the
signal is asserted when at a high volt-
age level.
