Non-PCI Single-Chip Full Duplex Ethernet Controller with Magic Packet
PCMCIA interface
68000 interface
EEPROM interface
Encoder/decoder with AUI interface
10BASE-T transceiver
High performance:
Chained ("Back-to-back") packet handling with no CPU intervention:
Queues transmit packets
Queues receive packets
Stores results in memory along with packet
Queues interrupts
Optional single interrupt upon completion of transmit chain
Fast block move operation for load/unload:
CPU sees packet bytes as if stored continuously.
Handles 16 bit transfers regardless of address alignment.
Access to packet through fixed window.
Fast bus interface:
Compatible with LOCAL BUS type and faster buses.
Flexibility:
Flexible packet and header processing:
Can be set to Simultasking - Early Receive and Transmit modes. With enhanced Early Receive
functions.
Can access any byte in the packet.
Can immediately remove undesired packets from queue.
Can move packets from receive to transmit queue.
Can alter receive processing order without copying data.
Can discard or enqueue again a failed transmission.
Resource allocation:
Memory dynamically allocated for transmit and receive.
Can automatically release memory on successful transmission.
Configuration:
LOCAL BUS:
Uses non-volatile jumperless setup via serial EEPROM.
PCMCIA:
Uses ROM or Flash ROM for attribute memory storage and optional serial EEPROM for IEEE
address storage. PCMCIA I/O ignores address lines A4-A15 and relies on the PCMCIA host,
decoding for the slot.
nROM/nPCMCIA, on LAN91C96, is left open with a pullup for LOCAL BUS mode. This pin is
sampled at the end of RESET. If found low, the LAN91C96 is configured for PCMCIA mode.
