GENERAL DESCRIPTION
The PCnet-SCSI combination Ethernet and 8-bit Fast
SCSI controller with a 32-bit PCI bus interface is a highly
integrated Ethernet-Fast SCSI system solution de-
signed to address high-performance system application
requirements. This single-chip is a flexible bus-master-
ing device that can be used in many applications, includ-
ing network- and SCSI-ready PCs, printers, fax
modems, and bridge/router designs. The bus-master
architecture provides high data throughput in the sys-
tem and low CPU and system bus utilization. The
PCnet-SCSI controller is fabricated with AMD’s ad-
vanced low-power CMOS process to provide low oper-
ating and standby current for power sensitive
applications.
