LAN91C95

ISA/PCMCIA Full Duplex Single-Chip Ethernet and Modem Controller with RAM

SMSC -> Microchip 

Fast bus interface:

Compatible with ISA type and faster buses

Flexibility:

Flexible packet and header processing:

Can be set to Simultasking - Early

Receive and transmit modes

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:

ISA:

Uses non-volatile jumperless setup via

serial EEPROM

PCMCIA:

Uses serial EEPROM for attribute

memory storage. PCMCIA I/O ignores

address lines A4-A15 and relies on the

PCMCIA host, decoding for the slot

nROM/nPCMCIA on the LAN91C95 is left

open with a pullup for ISA mode. This pin

is sampled at the end of Power On Reset.

If found low, the LAN91C95 is configured

for PCMCIA mode.
