The LAN91C96 is a VLSI Ethernet Controller that combines Local Bus, PCMCIA, and Motorola 68000 bus?interfaces in one chip. LAN91C96 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 LAN91C96 interfaces to external?transceivers via the provided AUI port. Only one additional IC is required for most applications. The?LAN91C96 com
