Product Summary

The AC82GM45 is an Express Chipset. It provides 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 reliability. The AC82GM45 consists of the Intel 82GM45 Graphics Memory Controller Hub (GMCH), and the Intel I/O Controller Hub 9M (ICH9M), available in three SKUs. The AC82GM45 provides 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.

Features

AC82GM45 features: (1)Advanced packaging technology and industry-leading electrical design innovations deliver long-term system reliability over a broad spectrum of operating conditions; (2)Direct Media Interface chip interconnect between the GMCH and the ICH can be implemented at x4 or x2 widths, providing up to 1 GB/s in each direction in full duplex; (3)12 USB 2.0 ports may be controlled by up to two high-speed Enhanced Host Controller Interfaces (EHCI) or up to six Universal Host Controller Interfaces. Each EHCI allows data transfers of up to 480 Mb/s; (4)Up to six PCI Express root ports on the ICH are configurable as six single x1 ports or partially ganged together as one x4 port and two x1 ports. Each root port allows transfer rates of up to 2.5 GB/s in each direction; (5)Intel High Definition Audio interface delivers premium digital multi-channel sound.
