PRELIMINARY
The PCnet-32 controller is a complete Ethernet node
integrated into a single VLSI device. It contains a bus
interface unit, a DMA buffer management unit, an ISO
8802-3 (IEEE/ANSI 802.3)-dened media access con-
trol (MAC) function, individual 136-byte transmit and
128-byte receive FIFOs, an ISO 8802-3 (IEEE/ANSI
802.3)-dened attachment unit interface (AUI) and
twisted-pair transceiver medium attachment unit
(10BASE-T MAU), and a microwire EEPROM interface.
The PCnet-32 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 con-
trollers in the PCnet family, including the PCnet-ISA
controller (Am79C960), the PCnet-ISA+ controller
(Am79C961), PCnet-ISA II (Am79C961A), and the
PCnet-PCI II controller (Am79C970A). The buffer man-
agement unit suppo rts the LANCE, IL A CC
(Am79C900), and PCnet descriptor software models.
The PCnet-32 controller is software-compatible with
Novell NE2100 and NE1500 Ethernet adapter card ar-
chitectures. In addition, a Sleep function has been in-
corporated to provide low standby current, which is
essential for notebooks and Green PCs.
The 32-bit demultiplexed bus interface unit provides a
direct interface to the VESA VL-Bus and 486 series
microprocessors, simplifying the design of an Ethernet
node in a PC system. With its built-in support for both
little and big endian byte alignment, this controller also
addresses proprietary non-PC applications.
Key PCnet-32 conguration parameters, including the
unique IEEE physical address, can be read from an ex-
ternal non-volatile memory (serial EEPROM) immedi-
ately following system reset. In addition, the I/O
location at which the internal registers are accessed
may be stored in the EEPROM, allowing the software
model of the device to be located appropriately in sys-
tem I/O space during system initialization.
The controller has the capability to select automatically
either the AUI port or the twisted-pair transceiver. Only
one interface is active at any one time. The individual
transmit and receive FIFOs reduce system overhead,
providing sufcient latency during frame transmission
and reception, and minimizing intervention during nor-
mal network error recovery. The integrated Manchester
encoder/decoder (MENDEC) eliminates the need for
an external serial interface adapter (SIA) in the node
system. The built-in general purpose serial interface
(GPSI) allows the MENDEC to be bypassed. In addi-
tion, the device provides programmable on-chip LED
drivers for transmit, receive, collision, receive polarity,
link integrity, or jabber status. The PCnet-32 controller
also provides an external address detection interface
(EADI) to allow external hardware address ltering in
internetworking applications.
