GENERAL DESCRIPTION
The Am79C971 controller is a single-chip 32-bit full-duplex, 10/100-Megabit per second (Mbps) highly integrated Ethernet system solution, designed to address high-performance system application requirements. It is a flexible bus mastering device that can be used in any application, including network-ready PCs and bridge/router designs. The bus master architecture provides high data throughput in the system and low CPU and system bus utilization. The Am79C971 controller is fabricated with AMD’s advanced low-power Complementary Metal Oxide Semiconductor (CMOS) process to provide low operating and standby current for power sensitive applications.
