GENERAL DESCRIPTION
The PCnet-PCI single-chip 32-bit Ethernet controller is
a highly integrated Ethernet system solution designed to
address high-performance system application require-
ments. It is a flexible bus-mastering device that can be
used in any application, including network-ready PCs,
printers, fax modems, and bridge/router designs. The
bus-master architecture provides high data throughput
in the system and low CPU and system bus utilization.
The PCnet-PCI controller is fabricated with AMD’s ad-
vanced low-power CMOS process to provide low oper-
ating and standby current for power sensitive
applications.
The PCnet-PCI controller is a complete Ethernet node
integrated into a single VLSI device. It contains a bus in-
terface unit, a DMA buffer management unit, an IEEE
802.3-defined Media Access Control (MAC) function, in-
dividual 136-byte transmit and 128-byte receive FIFOs,
an IEEE 802.3-defined Attachment Unit Interface (AUI)
and Twisted-Pair Transceiver Media Attachment Unit
(10BASE-T MAU), and a Microwire EEPROM interface.
The PCnet-PCI controller is also register compatible
with the LANCE (Am7990) Ethernet controller, the
C-LANCE (Am79C90) Ethernet controller, the ILACC
(Am79C900) Ethernet controller, and all Ethernet
