Processor
The GW2342 supports the Intel
IXP420, IXP422 and IXP425 processors. The
features common to these processors are listed below. The primary difference
between these processors is support for encryption, operating speed, operating
temperature and cost. See the following table below for the differences between
the processor families.

IXP42x Processor Feature Comparison
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. The Gateworks
standard shipping configuration is 64Mbytes.
Flash
The Flash resides in one or two J3 Intel StrataFlash
devices soldered directly to
the board. This architecture supports Flash memory capacities from 4Mbytes up
to 32Mbytes. The 16-bit Flash interface operates at 33MHz. The Gateworks
standard shipping configuration is 16Mbytes.
Compact Flash
The GW 2342 supports a single Compact Flash socket located on the rear of the
board. The Compact Flash socket accepts small removable mass storage cards
with storage capacities up to 4Gbytes.
