Introduction
The Intel® Atom™ Processor D400 and D500 Series processors are built on 45-nanometer Hi-K process technology. The processor is designed for a two-chip platform as opposed to the traditional three-chip platforms (processor, GMCH, and ICH). The two-chip platform consists of a processor and the chipset and enables higher performance, lower cost, easier validation, and improved x-y footprint
