GENERAL DESCRIPTION
The LAN91C94 is a VLSI Ethernet Controller that combines ISA and PCMCIA interfaces in one chip. LAN91C94 integrates all the 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 LAN91C94 interfaces to external transceivers via its AUI port. Only one additional IC is required on most applications. The LAN91C94 occupies 16 I/0 locations and no memory space except for PCMCIA attribute memory space.
