Product Summary

The FW82801DB is an I/O Controller Hub 4 Mobile. It incorporates a variety of PCI functions that are divided into three logical devices (29, 30, and 31) on PCI Bus 0 and one device on Bus 1. Device 30 is the Hub Interface-To-PCI bridge. Device 31 contains all the other PCI functions, except the USB Controllers and the LAN Controller.The FW82801DB PCI interface provides a 33-MHz, Rev. 2.2 compliant implementation. All PCI signals are 5-V tolerant, except PME#. The FW82801DB integrates a PCI arbiter that supports up to six external PCI bus masters in addition to the internal ICH4 requests.
