On-chip 10BASE-T filters allow designers to
use simple isolation transformers instead of
more costly filter/transformer packages.
The serial EEPROM port, used for configu-
ration and initialization, eliminates the need
for expensive switches and jumpers.
The CS8920A is designed to be used on a
2-layer circuit board instead of a more ex-
pensive multi-layer board.
The CS8920A-based solution offers the
smallest footprint available, saving valuable
printed circuit board area.
A set of certified software drivers is available
at no charge, eliminating the need for costly
software development.
High Performance
The CS8920A is a full 16-bit Ethernet controller
designed to provide optimal system performance
by minimizing time on the ISA bus and CPU
overhead per frame. It offers equal or superior
performance for less money when compared to
other Ethernet controllers. The CS8920A’s Pack-
etPage architecture allows software to select
whichever access method is best suited to each
particular CPU/ISA-bus configuration. When
compared to older I/O-space designs, PacketPage
is faster, simpler and more efficient.
To boost performance further, the CS8920A in-
clude several key features that increase
throughput and lower CPU overhead, including:
StreamTransfer cuts up to 87% of interrupts
to the host CPU during large block transfers.
Auto-Switch DMA allows the CS8920A to
maximize throughput while minimizing
missed frames.
Early interrupts allow the host to preprocess
incoming frames.
On-chip buffering of full frames cuts the
amount of host bandwidth needed to manage
Ethernet traffic.
Low Power and Low Noise
For low power needs, the CS8920A offers three
power-down options: Hardware Standby, Hard-
ware Suspend, and Software Suspend. In
Standby mode, the chip is powered down with
the exception of the 10BASE-T receiver, which
is enabled to listen for link activity. In either
Hardware or Software Suspend mode, the re-
