General Description

   The LAN91C96I is a VLSI Ethernet Controller that combines Local Bus interfaces in one chip. LAN91C96I integrates all MAC and physical layer functions, as well as the packet RAM, needed to implement a high performance 10BASE-T (twisted pair) node. For 10BASE5 (thick coax), 10BASE2 (thin coax), and 10BASE-F (fiber) implementations, the LAN91C96I interfaces to external transceivers via the provided AUI port. Only one additional IC is required for most applications. The LAN91C96I comes with Full Duplex Switched Ethernet (FDSWE) support allowing the controller to provide much higher throughput. 6K bytes of RAM is provided to support enhanced throughput and compensate for any increased system service latencies. The controller implements multiple advanced powerdown modes including Magic Packet to conserve power and operate more efficiently. The LAN91C96I can directly interface with the Local Bus and deliver no-wait-state operation. For Local Bus interfaces, the LAN91C96I occupies 16 I/0 locations and no memory space.
