Geode™ SC2200
Thin Client On a Chip
General Description
The Geode™ SC2200 Thin Client On a Chip device is a
member of the National Semiconductor^® IA (Information
Appliance) on a Chip family of fully integrated x86 system
chips. The Geode SC2200 includes:
• The Geode GX1 processor module combines advanced
CPU performance with Intel MMX support, fully acceler-
ated 2D graphics, a 64-bit synchronous DRAM
(SDRAM) interface, a PCI bus controller, and a display
controller.
• A low-power CRT and TFT Video Processor module with
a Video Input Port (VIP), and a hardware video acceler-
ator for scaling, filtering, and color space conversion.
• The Core Logic module includes: PC/AT functionality, a
USB interface, an IDE interface, a PCI bus interface, an
LPC bus interface, Advanced Configuration Power Inter-
face (ACPI) version 1.0 compliant power management,
and an audio codec interface.
• The SuperI/O module has: three serial ports (UART1,
UART2, and UART3 with fast infrared), a parallel port,
two ACCESS.bus (ACB) interfaces, and a real-time
clock (RTC).
The block diagram shows the relationships between the
modules.
These features, combined with the device’s small form fac-
tor and low power consumption, make it ideal as the core
for a thin client application.
