GENERAL DESCRIPTION
The Am79C90 CMOS Local Area Network Controller
for Ethernet (C-LANCE) is a 48-pin VLSI device de-
signed to greatly simplify interfacing a microcomputer or
minicomputer to an IEEE 802.3/Ethernet Local Area
Network. The C-LANCE, in conjunction with the
Am7992B Serial Interface Adapter (SIA), Am7996 or
Am79C98 and Am79C100 Transceiver, and closely
coupled local memory and microprocessor, is intended
to provide the user with a complete interface module for
an Ethernet network. The Am79C90 is designed using
a scalable CMOS technology and is compatible with a
variety of microprocessors. On-board DMA, advanced
buffer management, and extensive error reporting and
diagnostics facilitate design and improve system
performance.
