100/10Mbps Ethernet Controller

W89C840AF is a highly integrated Ethernet LAN controller for both 100BaseT and 10BaseT Ethernet. It provides a host bus interface complying with the PCI local bus specification revision 2.1, and the MII interface complying with the IEEE802.3u standard for easily implementing an Ethernet LAN adapter. The built-in 2K bytes transmit FIFO and 4K bytes receive FIFO, controlled by the on-chip bus master, are designed for improving network performance and reducing the host bus utilitzation.
