General Description

The AMD Geode™ SC1200 and SC1201 processors are
members of the AMD Geode processor family of fully inte-
grated x86 system chips. The SC1200/SC1201 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 hardware video accelerator for scaling, filtering, and
color space conversion, a Video Input Port (VIP), and an
NTSC/PAL TV encoder. The SC1201 (only) processor
has Macrovision copy protection support (see "Macrovi-
sion Product Notice" on page 441).

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 set-top box or an advanced multimedia-
type device.

Figure 1-1 shows the relationships between the modules.
