™ System On a Chip
General DescriptionThe Geode™ SC3200 WebPAD™ System 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 SC3200 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 TFT Video Processor module with a Video
Input Port (VIP), and a hardware video accelerator 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 WebPAD™ system application.
