Am79C978

Ethernet controllers in the PCnet Family (except

ILACC ™ ( A m79C90 0) ) , inc l u d ing P C net- I SA

(Am79C960), PCnet-ISA+ (Am79C961), PCnet-ISA II

(Am79C961A), PCnet-32 (Am79C965A), PCnet-PCI

(Am79C970), PCnet-PCI II (Am79C970A), PCnet-

FAST (Am79C971), and PCnet-FAST+ (Am79C972).

The Buffer Management Unit supports the LANCE and

PCnet descriptor software models.

While consuming minimal network resources, AMD’s

innovative any1Home™ Link Detection Packet for

HomePNA networks provides a means to indicate to

the MAC and thus the upper layers of the system pro-

tocol that a valid network (as defined by Home Net-

working Alliance) has been detected. The Link

Detection Packet is also capable of detecting a network

failure and allows the upper layer protocol to take cor-

rective action. Thus, the Link Detection Packet ensure

strict compliance to the Microsoft PC97, PC98, and

Home PNA requirements.

The integrated Am79C978 controller supports auto-

configuration in the PCI configuration space. Additional

integrated controller configuration parameters, includ-

ing the unique IEEE physical address, can be read

from an external non-volatile memory (EEPROM) im-

mediately following system reset.

In addition, the Am79C978 controller provides pro-

grammable on-chip LED drivers for transmit, receive,

collision, link integrity, Magic Packet status, speed, ac-

tivity, power output, address match, full-duplex, or 100

Mbps status.
