User’s Manual for Advantech SOM-A2558 series module V1.00
5
Based on SOM-A200 architecture to design, SOM-A255x (SOM-A2552,
SOM-A2558 and SOM-A255F) series have two kinds of PCB form factors.
l SOM-A2552 & SOM-A2558 series: 68mm x 68mm x 6.8mm
l SOM-A255F series: 68mm x 102mm x 6.8mm
SOM-A2558 benefit The SOM-A2558 series are very compact (68mm x 68mm x 6.8mm) and
highly integrated system module. SOM-A2558 series products have a
standardized form factor and standardized connectors (DDR-SODIMM
Memory Connector and two 100-pin board-to-board connectors) that carry a
specified set of signals. This standardization allows users to create
application-specified User Solution Board (CSB) which can accept a variety of
present and future SOM-A200 series modules.
SOM-A2558 series include popular & common peripheral functions such
as serial ports, LAN, USB, PCI, etc. The CSB designer can optimize exactly
how each of these functions is physically implemented. Connectors can be
placed precisely where they are needed for the application, on a baseboard
designed to optimally fit the system configuration and layout.
A CSB design may be used with a range of SOM-A2558 modules. This
flexibility can be used to differentiate products at various price/ performance
points, or to design “future proof” systems that have a built-in upgrade path.
The modularity of an SOM-A2558 solution also insures against obsolescence
as computer technology continues to evolve. A properly designed SOM-A2558
CSB can be used with several successive generations of SOM-A2558
modules. An SOM-A2558 CSB design thus has many of the advantages of a
custom computer board design, but delivers better obsolescence protection,
greatly reduced engineering effort, and faster time to market.
Based embedded platform integrates both low-level hardware and
software design and is always agreed to require heavy R&D resources, huge
development effort, risk as well as long time to market lead-time. Moreover,
the fast develop RISC SoC technology and short product life that has been
challenging System Integrators how to make a right product development
approach while foreseeing the huge advantage & benefit by adopting
RISC-base solution.
SOM-A2558 series are an innovate platform architecture of
WinCE.NET-ready complete functional system in a low profit module with
SODIMM 200-pin unified I/O ready bus interface that is designed to fit into
application-specified User Solution Board (CSB) with easy, risk-less, robust,
fast implementation approach. Dual expansion interface and Pre-select
Embedded OS also are well integrated on module. OS Board Support
Package (BSP) and advantech own-develop system utility & tools are also
supported for an easy design-in business philosophy.
SOM-A2558 series is designed for Ideal for power critical & I/O intensive
