User’s Manual for Advantech SOM-A2558 series module V1.00

Based on SOM-A200 architecture to design, SOM-A255x (SOM-A2552, SOM-A2558 and SOM-A255F) series have two kinds of PCB form factors.

•SOM-A2552 & SOM-A2558 series: 68mm x 68mm x 6.8mm

•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-pinunified 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-inbusiness philosophy.
