GENERAL DESCRIPTION
The 32-bit PCnet-PCI II single-chip full-duplex Ethernet
controller is a highly integrated Ethernet system solution
designed to address high-performance system applica-
tion requirements. It is a flexible bus-mastering device
that can be used in any application, including network-
ready PCs, printers, fax modems, and bridge/router de-
signs. The bus-master architecture provides high data
throughput in the system and low CPU and system bus
utilization. The PCnet-PCI II controller is fabricated with
AMD’s advanced low-power CMOS process to
provide low operating and standby current for power
sensitive applications.
