PC/104-Plus IDEA FAMILY - COMMUNICATION MODULES
The complete embedded PC solution
COM-1450 10/100Mbit Ethernet adapter SHORT FORM
ETH0998V3D02
GENERAL DESCRIPTION
The COM-1450 is a high performance PCI
100BaseT Ethernet card in a PC/104-PLUS
form factor. It is designed to provide flexibility
and compatibility with any existing PC
applications. Do to its high integration this
module is intended for embedded rugged
application where reliability is required.
The COM-1450 is a bus mastering PCI
Ethernet card using the Digital Semiconductor
21140 Ethernet chip. The bus mastering
architecture of the 21140 minimizes CPU
involvement in packet transmission and
reception. The large receive and transmit
FIFOs permit efficient operation even with high
system latencies. The 21140 chip was chosen
for its high performance, advanced feature
set, and wide range of available drivers. The
modules supports full autonegotiation for
automatic selection of all twisted media types.
Full duplex operation is supported on
100BaseT and 10BaseT modes.The
COM1450 is a universal type PC/104-PLUS
card compatible with 3.3V and 5V bus
systems. The modules require 3,3V and 5V
power . The 100BaseT interface of the PHY is
powered down when using 10BaseT. All
options are software selectable except the PCI
slot number. A MII compatible connector is
available for use with other media types. A
socket for a PLCC boot ROM is provided.
Due to the high integration the consumption is
below 2W.
