Am79C970A
The PCnet-PCI II controller is a complete Ethernet node
integrated into a single VLSI device. It contains a bus
interface unit, a DMA buffer management unit, an IEEE
802.3-compliant Media Access Control (MAC) function,
individual 272-byte transmit and 256-byte receive
FIFOs, an IEEE 802.3-compliant Attachment Unit
Interface (AUI) and Twisted-Pair Transceiver Media
Attachment Unit (10BASE-T MAU) that can both
operate in either half-duplex or full-duplex mode.
The PCnet-PCI II controller is register compatible with
the LANCE (Am7990) Ethernet controller, the
C-LANCE (Am79C90) Ethernet controller, the ILACC
(Am79C900) Ethernet controller, and all Ethernet
controllers in the PCnet Family, including the
PCnet-ISA
controller
(Am79C960),
controller (Am79C961), PCnet-ISA II controller
(Am79C961A), PCnet-32 controller (Am79C965),
PCnet-PCI controller (Am79970), and the PCnet-SCSI
controller (Am79C974). The buffer management unit
supports the C-LANCE, ILACC, and PCnet descriptor
software models. The PCnet-PCI II controller is
software compatible with the Novell
NE2100 and
NE1500 Ethernet adapter card architectures.
PCnet-ISA+
The 32-bit multiplexed bus interface unit provides a di-
rect interface to PCI local bus applications, simplifying
the design of an Ethernet node in a PC system. The
PCnet-PCI II controller provides the complete interface
to an Expansion ROM, allowing add-on card designs
with only a single load per PCI bus interface pin. With its
built-in support for both little and big endian byte align-
ment, this controller also addresses proprietary non-PC
applications.
The
PCnet-PCI
advanced CMOS design allows the bus interface to be
connected to either a 5 V or a 3.3 V signaling environ-
ment. Both NAND Tree and JTAG test interfaces
are provided.
II
controller’s
The PCnet-PCI II controller supports automatic
configuration in the PCI configuration space. Additional
PCnet-PCI II configuration parameters, including the
unique IEEE physical address, can be read from an ex-
ternal non-volatile memory (Microwire EEPROM) im-
mediately following system reset.
The controller has the capability to automatically select
either the AUI port or the Twisted-Pair transceiver. Only
one interface is active at any one time. Both network in-
terfaces can be programmed to operate in either half-
duplex or full-duplex mode. The individual transmit and
receive FIFOs optimize system overhead, providing suf-
ficient latency during frame transmission and reception,
and minimizing intervention during normal network error
recovery. The integrated Manchester encoder/decoder
(MENDEC) eliminates the need for an external Serial In-
terface Adapter (SIA) in the system. The built-in General
Purpose Serial Interface (GPSI) allows the MENDEC to
be
by-passed.
In
provides programmable on-chip LED drivers for trans-
mit, receive, collision, receive polarity, link integrity, ac-
tivity, or jabber status. The PCnet-PCI II controller also
provides an External Address Detection Interface
(EADI) to allow fast external hardware address filtering
in internetworking applications.
addition,
the
device
For power sensitive applications where low stand-by
current is desired, the device incorporates two Sleep
functions to reduce over-all system power consumption,
excellent for notebooks and Green PCs. In conjunction
with these low power modes, the PCnet-PCI II controller
also has integrated functions to support Magic Packet,
an inexpensive technology that allows remote wake up
of Green PCs.
