1.1General 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 1-1shows the relationships between the modules.
