AM79C978 - Advanced Micro Devices

AM79C978 Single-Chip 1/10 Mbps PCI Home Networking Controller

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 dev.
