SC2200 Datasheet | National Semiconductor

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 bines 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 pliant power management, and an audio codec interface. - The Super I/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 , bined with the device’s small form factor and low power consumption, make it ideal as the core for a thin client application.
