PCnet
-ISA II Jumperless, Full Duplex Single-Chip
Ethernet Controller for ISA
DISTINCTIVE CHARACTERISTICS
Single-chip Ethernet controller for the Industry
Standard Architecture (ISA) and Extended
Industry Standard Architecture (EISA) buses
I
Supports IEEE 802.3/ANSI 8802-3 and Ethernet
standards
I
Supports full duplex operation on the
10BASE-T, AUI, and GPSI ports
I
Direct interface to the ISA or EISA bus
I
Pin compatible to Am79C961 PCnet-ISA
Jumperless Single-Chip Ethernet Controller
I
Software compatible with AMD’s Am7990
LANCE register and descriptor architecture
I
Low power, CMOS design with sleep mode
allows reduced power consumption for critical
battery powered applications
I
Individual 136-byte transmit and 128-byte
receive FIFOs provide packet buffering for
increased system latency, and support the
following features:
— Automatic retransmission with no FIFO
reload
— Automatic receive stripping and transmit
padding (individually programmable)
— Automatic runt packet rejection
— Automatic deletion of received collision
frames
I
Dynamic transmit FCS generation
programmable on a frame-by-frame basis
I
Single +5 V power supply
I
Internal/external loopback capabilities
I
Supports 8K, 16K, 32K, and 64K Boot PROMs or
Flash for diskless node applications
I
Supports Microsoft’s Plug and Play System
configuration for jumperless designs
I
Supports staggered AT bus drive for reduced
noise and ground bounce
I
+
I
Supports 8 interrupts on chip
Look Ahead Packet Processing (LAPP)
allows protocol analysis to begin before
end of receive frame
Supports 4 DMA channels on chip
Supports 16 I/O locations
Supports 16 boot PROM locations
Provides integrated Attachment Unit Interface
(AUI) and 10BASE-T transceiver with 2 modes of
port selection:
— Automatic selection of AUI or 10BASE-T
— Software selection of AUI or 10BASE-T
Automatic Twisted Pair receive polarity
detection and automatic correction of the
receive polarity
Supports bus-master, programmed I/O, and
shared-memory architectures to fit in any PC
application
Supports edge and level-sensitive interrupts
DMA Buffer Management Unit for reduced CPU
intervention which allows higher throughput by
by-passing the platform DMA
JTAG Boundary Scan (IEEE 1149.1) test access
port interface for board level production test
Integrated Manchester Encoder/Decoder
Supports the following types of network
interfaces:
— AUI to external 10BASE2, 10BASE5,
10BASE-T or 10BASE-F MAU
— Internal 10BASE-T transceiver with Smart
Squelch to Twisted Pair medium
Supports LANCE General Purpose Serial
Interface (GPSI)
132-pin PQFP package
