General Description
The LAN91C110 is designed to facilitate the implementation of second generation Fast Ethernet PC Card adapters and other non-PCI connectivity products. The LAN91C110 is a digital device that implements the Media Access Control (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 toensure that the CPU to packet RAM data movement does not cause a bottleneck at 100 Mbps.
