Introduction
1 Introduction
The Intel® System Controller Hub (Intel® SCH) is a component of Intel® Atom™
processor technology. The Intel® SCH combines functionality normally found in
separate GMCH (integrated graphics, processor interface, memory controller) and ICH
(on-board and end-user I/O expansion) components into a single component
consuming less than 2.3 W of thermal design power. The features of the Intel® SCH
provide functionality necessary for traditional operating systems (such as Microsoft
Windows Vista* or Linux*) as well as functionality normally associated with handheld
devices (such as SDIO/MMC and USB client). The Intel® SCH was designed to be used
with the Intel® Atom™ processor Z5xx series processor. Figure 1 shows an example
system block diagram. Section 1.3 provides an overview of the major features of the
Intel® SCH.
This document is the datasheet for the Intel System Controller Hub component. The
document content includes signal description, system memory map, register
descriptions, a description of the Intel® SCH interfaces and major functional units,
electrical characteristics, ballout definitions, and package characteristics.
