Introduction

The AMD Geode™ SC3200 processor is a member of the AMD Geode™ family of fully integrated x86 system chips. The SC3200 single-chip processor includes a 32-bit x86-compatible AMD Geode™ GX1 processor, a TFT video processor, core logic, and selected Super I/O functions. Excluding memory and the wireless communications subsystem, the features on the Geode SC3200 processor provide all the functionality needed to create a small form factor and low power consumption wireless WebPAD Personal Access Device (PAD).

x86 Architecture

The x86 architecture means Internet compatibility. With more than 300 Web plug-ins written to run exclusively on x86 processors, the Geode processor family provides a Web experience unattainable with non-x86 based architectures.

The integrated architecture of the SC3200 processor simplifies system design by reducing component count, the size of the main system board, and overall system power consumption. It can significantly lower overall system costs while improving time-to-market.

Technical Specifications

Primary Components

• The AMD Geode™ SC3200 processor is based on the AMD Geode™ GX1 processor’s integrated core which combines advanced CPU performance with MMX™ support, fully accelerated 2D graphics, a 64-bit synchronous DRAM (SDRAM) interface, and an internal PCI bus controller
• Low power consumption TFT display processor, with a hardware video accelerator for scaling, filtering, and color space conversion
• Core Logic module includes PC AT functionality, a Universal Serial Bus (USB) interface, video input port, ACPI 1.0 compliant power management, and an audio codec interface
• Super I/O block, including two serial ports, an infrared (IR) port, an ACCESS.bus™ interface, and a Real Time Clock (RTC)
