General Description
●The AT/LANTIC AT Local Area Network Twisted-pair Interface Controller is a CMOS VLSI device designed for easy implementation of CSMA/CD local area networks.
●Unique to the AT/LANTIC is the integration of the entire bus interface for PC-ATÉ ISA (Industry Standard Architecture) bus based systems. Hardware and software selectable options allow the AT/LANTIC’s bus interface to be configured software compatible to either an NE2000 or Ethercard PLUS16TM. All bus drivers and control logic are integrated to reduce board cost and area.
●Features
●■ Controller and integrated bus interface solution for IEEE 802.3, 10BASE5, 10BASE2, and 10BASE-T
●■ Software compatible with NovellÉ’s NE2000/Plus industry standard Ethernet Adapters
●■ Selectable buffer memory size
●■ No external bus logic or drivers
●■ Integrated controller, ENDEC, and transceiver
●■ Full IEEE 802.3 AUI interface
●■ Single 5V supply
●10BASE-T TRANSCEIVER MODULE:
