SC1100 Datasheet | National Semiconductor

Description The Geode™ SC1100 device is a member of the National Semiconductor® Information Appliance On a Chip (IAOC) family of fully integrated x86 system chips. The main modules of the Geode SC1100 are: - Geode GX1 processor module - bines advanced CPU performance with Intel MMX support, a 64-bit synchronous DRAM (SDRAM) interface, and a PCI bus controller. - 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. - Super I/O module - Has a Serial Port (UART), an Infrared (IR) interface, 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 an advanced set-top box, consumer access device, residential gateway, thin client, or embedded system.
