sonal Computers. Its highly-integrated design
eliminates the need for costly external components
required by other Ethernet controllers. The
CS8900A includes on-chip RAM, 10BASE-T trans-
mit and receive filters, and a direct Bus interface
with 24 mA Drivers.
In addition to high integration, the CS8900A offers
a broad range of performance features and config-
uration options. Its unique PacketPage architec-
ture automatically adapts to changing network
traffic patterns and available system resources.
The result is increased system efficiency. The
CS8900A is available in a 100-pin TQFP package
ideally suited for small form-factor, cost-sensitive
Ethernet applications. With the CS8900A, system
engineers can design a complete Ethernet circuit
that occupies less than 1.5 square inches (10 sq.
cm)ofboardspace.

Key Benefits
Very Low Cost
The CS8900A is designed to provide the lowest-
cost Ethernet solution available for embedded
applications, portable motherboards, and adapter
cards. Cost-saving features include:
•Integrated RAM eliminates the need for expensive
external memory chips.
•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 configuration
and initialization, eliminates the need for expen-
sive switches and jumpers.
•The CS8900A is designed to be used on a 2-layer
circuit board instead of a more expensive multi-
layer board.
•The 8900A-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 CS8900A is a full 16-bit Ethernet controller
designed to provide optimal system performance
by minimizing time on the bus and CPU overhead
per frame. It offers equal or superior performance
for less money when compared to other Ethernet
controllers. The CS8900A’s PacketPage architec-
ture allows software to select whichever access
method is best suited to each particular CPU/bus
configuration. When compared to older I/O-space
designs, PacketPage is faster, simpler and more
efficient.
To boost performance further, the CS8900A
includes 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 CS8900A to maxi-
mize 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 CS8900A 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 lis-
ten for link activity. In either Hardware or Software
Suspend mode, the receiver is disabled and power
consumption drops to the micro-ampere range.
In addition, the CS8900A has been designed for
very low noise emission, thus shortening the time
required for EMI testing and qualification.
Complete Support
The CS8900A comes with a suite of software driv-
ers for immediate use with most industry standard
network operating systems. In addition, complete
evaluation kits and manufacturing packages are
available, significantly reducing the cost and time
required to produce new Ethernet products.
