Intel® 4 Series Chipset Family Datasheet

Intel® 4 Series Chipset Family Datasheet

Chipset contains two components: GMCH (or MCH) for the host bridge and I/O Controller Hub 10 (ICH10) for the I/O subsystem (G45, G43, P45, P43 Express Chipset only). The ICH10 is the tenth generation I/O Controller Hub and provides a multitude of I/O related functions. The Intel G41 Chipset uses the I/O Controller Hub 7 (ICH7).

This document is the datasheet for the following components:
• Intel® 82Q45 Graphics and Memory Controller Hub (GMCH), which is part of the Intel® Q45 Chipset.
• Intel® 82Q43 Graphics and Memory Controller Hub (GMCH), which is part of the Intel® Q43 Chipset.
• Intel® 82B43 Graphics and Memory Controller Hub (GMCH), which is part of the Intel® B43 Chipset.
• Intel® 82G45 Graphics and Memory Controller Hub (GMCH), which is part of the Intel® G45 Chipset.
• Intel® 82G43 Graphics and Memory Controller Hub (GMCH), which is part of the Intel® G43 Chipset.
• Intel® 82G41 Graphics and Memory Controller Hub (GMCH), which is part of the Intel® G41 Chipset.
• Intel® 82P45 Memory Controller Hub (MCH), which is part of the Intel® P45 Chipset.
• Intel® 82P43 Memory Controller Hub (MCH), which is part of the Intel® P43 Chipset.

Topics covered include; signal description, system memory map, PCI register description, a description of the (G)MCH interfaces and major functional units, electrical characteristics, ballout definitions, and package characteristics.

Note: Unless otherwise specified, ICH10 refers to the Intel® 82801JIB ICH10, Intel® 82801JIR ICH10R, Intel® 82801JD ICH10D, Intel® 82801JDO ICH10DO I/O Controller Hub 10 components.

Note: For the 82G41 GMCH, references to ICH are references to ICH7/ICH7R.

Note: Unless otherwise specified, the information in this document applies to the Intel® 82Q45, 82Q43, 82B43, 82G45, 83G43, 82G41 Graphics and Memory Controller Hub (GMCH) and Intel® 82P45, 82P43 Memory Controller Hub (MCH).
