Geode™ SC2200 Thin Client On a Chip August 2002 Revision 3.0 Geode™ SC2200 Thin Client On a Chip General Description The Geode™ SC2200 Thin Client 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 SC2200 includes: The Geode GX1 processor module combines advanced CPU performance with Intel MMX support, fully accelerated 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 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 Interface (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 factor and low power consumption, make it ideal as the core for a thin client application.
