1.1General Description

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 1-1shows the relationships between the modules.
