LAN91C100
Description
The LAN91C100 FEAST is a high-speed network controller designed to facilitate the implementation of Fast Ethernet adapters and connectivity products. It contains a dual speed CSMA/CD engine that implements the MAC portion of the CSMA/CD protocol at 10 and 100 Mbps and couples it with a lean and fast data and control path system architecture to ensure data movement with no bottlenecks at 100 Mbps.
Key Features
