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.

VGA, LVDS, DVI, High Definition Multimedia Interface (HDMI)
and DisplayPort with integrated High-bandwidth Digital Copy
Protection (HDCP) technology. Dual independent display
support allows for flexible display configurations.
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.
