GENERAL DESCRIPTION
The Am79C978A controller is the first in a series of
home networking products from AMD. The Am79C978A
controller is fabricated in an advanced low power 3.3 V
CMOS process to provide low operating current for
power sensitive applications.
The Am79C978A controller contains an Ethernet Con-
troller based on the Am79C971 Fast Ethernet control-
ler, a physical layer device for supporting the 802.3
standard for 10BASE-T, and a physical layer device for
data networking at speeds up to 1 Mbps over ordinary
residential telephone wiring.
The integrated PCI Ethernet controller is a highly inte-
grated 32-bit full-duplex, 10/100 Mbps Ethernet con-
troller solution designed to address high-performance
system application requirements. It is a flexible bus-
mastering device that can be used in any application,
including network ready PCs. The bus master architec-
ture provides high data throughput and low CPU and
system bus utilization.
The integrated Ethernet transceiver is a physical layer
device supporting the IEEE 802.3 standards for
10BASE-T. It provides all of the PHY layer functions
required to support 10 Mbps data transfer speeds.
The integrated HomePNA transceiver is a physical
layer device that enables data networking at speeds up
to 1 Mbps over common residential phone wiring re-
gardless of topology and without disrupting telephone
(POTS) service.
The 32-bit multiplexed bus interface unit provides a di-
rect interface to the PCI local bus, simplifying the de-
sign of an Ethernet or home network node in a PC
system. The device has built-in support for both little
and big endian byte alignment. The integrated home
networking controller’s advanced CMOS design allows
the bus interface to be connected to either a +5.0 V or
a +3.3 V signaling environment. A compliant IEEE
1149.1 JTAG test interface for board level testing is also
provided, as well as a NAND tree test structure for
those systems that do not support the JTAG interface.
The integrated Am79C978A home networking controller
is also compliant with the PC98, PC99, and Net PC spec-
ifications. It includes the full implementation of the Mi-
crosoft OnNow and ACPI specifications, which are
backward compatible with Magic Packet technology, and
is compliant with the PCI Bus Power Management Inter-
face specification by supporting the four power manage-
ment states (D0, D1, D2, and D3), the optional PME pin,
and the necessary configuration and data registers.
The integrated Am79C978A home networking control-
ler is a complete Ethernet or home network node inte-
grated into a single VLSI device. It contains a bus
interface unit, a Direct Memory Access (DMA) Buffer
Management Unit, an ISO/IEC 88023 (IEEE 802.3)
compliant Media Access Controller (MAC), a Transmit
FIFO and a large Receive FIFO, and an IEEE 802.3u
compliant MII. Both IEEE 802.3 compliant full-duplex
and half-duplex operations are supported on the MII in-
terface. 10/100 Mbps operation is supported through
the MII interface.
The integrated Am79C978A home networking control-
ler is register compatible with the LANCE (Am7990)
and C-LANCE (Am79C90) Ethernet controllers and all
Ethernet controllers in the PCnet Family (
except
ILACC (Am79C900)), including PCnet-ISA
(Am79C960), PCnet-ISA+ (Am79C961), PCnet-ISA II
(Am79C961A), PCnet-32 (Am79C965A), PCnet-PCI
(Am79C970), PCnet-PCI II (Am79C970A), PCnet-
