Specifications of AM79C973BKD

• Lead Free Status / RoHS Status: Compliant

controllers also address non-PC applications. The
Am79C973 and Am79C975 controllers’ advanced
CMOS design allows the bus interface to be connected
to either a +5-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 cannot support the
JTAG interface.
The Am79C973 and Am79C975 controllers support
auto-configuration in the PCI configuration space. Ad-
ditional Am79C973 and Am79C975 controller configu-
ration parameters, including the unique IEEE physical
address, can be read from an external non-volatile
memory (EEPROM) immediately following system re-
set.
In addition, the Am79C973 and Am79C975 controllers
provide programmable on-chip LED drivers for trans-
mit, receive, collision, link integrity, Magic Packet sta-
tus, activity, link active, address match, full-duplex, 10
Mbps or 100 Mbps, or jabber status.

Am79C973/Am79C975
The Am79C973 and Am79C975 controllers are regis-
ter compatible with the LANCE™ (Am7990) Ethernet
controller, the C-LANCE™ (Am79C90) Ethernet con-
troller, and all Ethernet controllers in the PCnet™ Fam-
ily, except ILACC™ (Am79C900), including the PCnet-
ISA™ (Am79C960), PCnet-ISA+™ (Am79C961),
P C n e t - I S A I I ™ ( A m 7 9 C 9 6 1 A ) , P C n e t - 3 2 ™
( A m 7 9 C 9 6 5 ) ,
PCnet-PCI II™ (A m79C970A ), P Cnet- FAST™
(Am79C971), and PCnet-FAST+™ (Am79C972). The
Buffer Management Unit supports the LANCE and
PCnet descriptor software models.
The Am79C973 and Am79C975 controllers are ideally
suited for LAN on the motherboard, network adapter
card, and embedded designs. It is available in a 160-
pin Plastic Quad Flat Pack (PQFP) package and also in
a 176-pin Thin Quad Flat Pack (TQFP) package for
form factor sensitive designs.
