The W3100A offers system designers a quick,
Implementing this LSI into a system
easy way to add Ethernet networking functionality to
any product.
can completely offload Internet connectivity and
processing standard protocols from the system,
thereby
significantly
reducing
the
software
development cost.
The W3100A contains TCP/IP Protocol Stacks
such as TCP, UDP, IP, ARP and ICMP protocols, as
well as Ethernet protocols such as Data Link Control
and MAC protocol.
The W3100A offers a socket API (Application
Programming Interface) that is similar to the windows
socket API.
The chip offers Intel and Motorola

for upper-layer and supports standard MII interface for
under-layer Ethernet.
The W3100A can be applied to handheld devices
including Internet phones, VoIP SOC chips, Internet
MP3 players, handheld medical devices, LAN cards
for Web servers, cellular phones and many other non-
portable electronic devices such as large consumer
electronic products.G
