SDRAM
The DRAM resides in two synchronous DRAM devices soldered directly to the
board. This architecture supports SDRAM memory capacities from 32Mbytes up
to 128Mbytes. The 32-bit SDRAM interface operates at 133MHz.
Flash
The Flash resides in one or two J3 Intel StrataFlash
®
devices soldered directly to
the board. This architecture supports Flash memory capacities from 8Mbytes up
to 32Mbytes. The 16-bit Flash interface operates at 33MHz.
CompactFlash
The GW2345 supports a single CompactFlash socket located on the rear of the
board. The CompactFlash socket accepts small removable mass storage cards
with storage capacities up to 4Gbytes.
Mini-PCI Sockets
Mini-PCI is a small form factor PCI card that uses the same signal protocol,
electrical specifications, and configuration definitions as conventional PCI. There
are up to four Mini-PCI sockets available on the GW2345. There are a wide
variety of Mini-PCI cards available for expanding the networking functionality of
the GW2345.
Ethernet
The GW2345 includes a Micrel KS8995MA 5-port 10/100 managed switch
connected as a 1-port WAN and a 4-port LAN. The switch supports tag/port-
based VLAN, QoS priority, management, MIB counters and a dual MII interface.
The switch includes five 10/100 transceivers, a high-speed non-blocking switch
fabric, a dedicated address lookup engine, and frame buffer memory. Both
10Base-T and 100Base-TX architectures are supported. The WAN port is
available through a single RJ45 connector. The LAN ports are available through
a 1x4 gang RJ45 connector. All RJ45 connectors have two integrated status
lights. The green status light indicates link and activity. The light is on for link and
