GENERAL DESCRIPTION
The Am79C978 controller is the first in a series of home networking products from AMD. The Am79C978 controller is fabricated in an advanced low power 3.3 V CMOS process to provide low operating current for power sensitive applications.

The Am79C978 controller contains an Ethernet Controller based on the Am79C971 Fast Ethernet controller, a physical layer device for supporting the 802.3 standard for 10BASE-T, and a physical layer device for data networking at speeds up to 1 Mbps over ordinary residential telephone wiring.

The integrated PCI Ethernet controller is a highly integrated 32-bit full-duplex, 10/100 Mbps Ethernet controller solution designed to address high-performance system application requirements. It is a flexible busmastering device that can be used in any application, including network ready PCs. The bus master architecture provides high data throughput and low CPU and system bus utilization.
