NH82801HBM

Product Summary

The NH82801HBM is an I/O Controller. It provides extensive I/O support. The NH82801HBM incorporates a variety of PCI devices and function. The NH82801HBM is divided into seven logical devices. The first device is the DMI-To-PCI bridge. The second device contains most of the standard PCI functions that have existed in legacy PCI-to-ISA bridges (South Bridges). The third and fourth devices are the USB host controller devices. The fifth device is PCI Express device. The sixth device is the Intel HD Audio controller device, and the seventh device (Device 25) is the GbE controller device.
