    10Based-T Ethernet Controller

     

    产品信息

    Please consider this device


    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 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 power-down modes including Magic Packet to conserve power and operate more efficiently. The LAN91C96 can directly interface with the Local Bus, PCMCIA, and 68000 buses and deliver no-wait-state operation.
