Product Summary

The FW82801DB is a highly integrated multifunctional communications I/O controller hub that provides the interface to the PCI bus and integrates many of the functions needed in today communications applications. It incorporates a variety of PCI functions that are divided into two logical devices (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 LAN controller .
