Intel® 82801AA (ICH) and Intel® 82801AB (ICH0) I/O Controller Hub

The ICH is a highly-integrated, multi-functional I/O Controller Hub that provides the interface to the PCI Bus and integrates many of the functions needed in today?s PC platforms. The ICH communicates with the host controller over a dedicated hub interface. There are two versions of the ICH (82801AA: ICH and 82801AB: ICH0). This provides added flexibility in designing cost-effective system solutions. These devices are pin compatible and are in 241-pin packages.
