General Description

The AMD Geode™ SC3200 processor is a member of the
AMD Geode family of fully integrated x86 system chips.
The SC3200 processor includes:
• The AMD Geode GX1 processor module combines
advanced CPU performance with MMX™ support, fully
accelerated 2D graphics, a 64-bit synchronous DRAM
(SDRAM) interface, a PCI bus controller, and a display
controller.
• A low-power TFT Video Processor module with a Video
Input Port (VIP), and a hardware video accelerator for
scaling, filtering, and color space conversion.

1.0Overview

• 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 WebPAD™ system application.
Figure 1-1 shows the relationships between the modules.
