Chipsets for Embedded Computing

Product Overview

The Mobile Intel® GM45, GS45, and GL40 Express chipsets provide

outstanding flexibility for developers of embedded applications

with excellent graphics, memory and I/O bandwidth, as well as

remote asset management capabilities, storage speed and reli-

ability. They address requirements of a broad range of embedded

applications such as retail and transaction solutions, gaming plat-

forms and industrial automation equipment. The Mobile Intel

GM45 and GS45 Express chipsets provide the same feature set

and functionality in different form factors, while the Mobile Intel

GL40 Express chipset offers a subset of features ideal for

value-oriented applications.

These chipsets consist of the Intel® 82GM45/82GS45/82GL40

Graphics Memory Controller Hub (GMCH), and the Intel® I/O

Controller Hub 9M (ICH9M), available in three SKUs. The ICH9M

delivers outstanding system performance through high-band-

width interfaces including PCI Express*, Serial ATA, and USB 2.0.
