General Description
The LAN91C96 is a VLSI Ethernet Controll er that combines Local Bus, PCMCIA, and Motorola 68 000 bus
interfaces in one chip. LAN91C96 integrates all MAC and physical layer functions, as well as the packet
RAM, needed to implem ent a high p erformance 10BASE-T (t wisted pair) node. For 10BA SE5 (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 Dupl ex Switched Ethernet (FDSWE) suppor t allowing the controller to provid e
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. For
Local Bus and PCMCIA interf aces, the LAN91C 96 occupies 16 I/0 l ocations and no memor y space except
for PCMCIA attribute memory space. The same I/O space is used for both LOCAL BUS and PCMCIA
operations. Its shared memory is sequentially accessed with 40ns access times to any of its registers,
including its packet memory. DMA services are not used by the LAN 91C96, virtually de-coup ling network
traffic from local or system bus utilization. For packet memory management, the LAN91C96 integrates a
unique hardware Memory Management Unit (MMU) with enhanced performance and decreased software
overhead when compared to ring buffer and linked list architectures. The LAN91C96 is portable to
different CPU and bus platforms due to its flexible bus interface, flat memory structure (no pointers), and
its loosely coupled buffered architecture (not sensitive to latency).
The LAN91C96 is availa ble i n 100-pi n QF P and TQ FP (1.0 mm body thickness) pack age s. T he low profile
TQFP is ideal for mobile applications such as PC Card LAN adapters. The LAN91C96 operates with a
single power supply voltage of 5.0V. Revisions E and later will also operate using a single 3.3V power
supply.
