Overview

The AMD Geode™ SC2200 processor is a member of the
AMD Geode processor family of fully integrated x86 system
chips. The SC2200 processor includes: 

• The Geode GX1 processor module combines advanced 

CPU performance with 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).

These features, combined with the device’s low power con-
sumption, enable a small form factor design making it ideal
as the core for a thin client application. 

Figure 1-1 shows the relationships between the modules.
