Chapter 1 SOM-A2558 series Architecture 1.1 Introduction
Advantech SOM-A2558 module uses a dual-chip design principle. SOM-A2558 series System On Module integrates both an Intel XScale PXA255 ultra low power CPU with Advantech's EVA-C210 companion chip. This offers the advantage of integrated controllers, but with multiple I/Os, such as CF, PCMCIA, USB Host, USB Client, RS-232/UART, PCI Bus Rev. 2.2, 10/100Base-T Ethernet, PS/2 ports and RS-485.
SOM-A2558 series Design highlight:
•68 mm x 68 mm x 6.8 mm compact size module
•Power management ready support with Normal, Idle, Suspend, Off mode utilities.
•OS-ready package for Windows CE .NET/Linux Installation (Windows CE .NET 4.2 BSP ready)
•Local bus(AMI Bus), comprehensive I/O interfaces as PS/2 port, Ethernet, USB Host and PCI I/F support
•Boot option by onboard Flash or CFC makes easy maintenance and cost savings
•Provide a variety of reconfi guration options to fulfi ll specifi c requirements
•Design-in Kit package is available for complete design-in support
•Optional RISC CE-Builder assists for customer own image development
SOM-A200 architecture
SOM-A255x series are based on Advantech SOM-A200 architecture to design. SOM-A200 is Advantech RISC ultra-low power series SOM architecture. The following block diagram is the SOM-A200 architecture.

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-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.

System Memory
SOM-A2558 SDRAM can be configured as 4/8/16/32/64/128/256MB. Users can base on their requirement to reconfigure the SDRAM size.
There are two functions Flash on SOM-A2558 series. One is Boot Flash, the other is Storage Flash.
Boot Flash is 1MB NOR flash. In standard SOM-A2558 series product, Advantech will pre-install the WinCE bootloader in it.
Storage Flash is used to save image & user APs. Storage Flash size is also reconfigurable. The Storage Flash is M-system Flash. Storage Flash size could be 0/16/32/64 MB. SOM-A2558 series have Multiple boot options through the on-board Flash or Compact Flash Card (CFC) for easy maintain and cost saving. If Storage Flash is 0MB that means user should put the image in Compact Flash Card.
CPLD
SOM-A2558 series have one CPLD on board. The CPLD take charges of the following function:
•System memory assignments
•I/O control
•RTC control
Base on Advantech policy, Advantech won’t release the CPLD code to user. In fact, when user designs their own target carrier board, they don’t need to know the CPLD code. Advantech will release memory map of available memory block and available GPIOs. These are fully enough to users to develop their own carrier board.

1.2.1 Mechanical Specification
Following figure shows the mechanical drawing of SOM-A2558 series.
The above figure shows the SOM-A2558 mechanical drawing. Users could follow the above figure to implement the layout procedure.
1st drawing shows the SOM-A2558 module PCB mechanical data. When users enter the layout procedure, user could follow the 1st drawing to place the connector. SOM-A2558 series PCB form factor is 68mm*68mm*68mm.
The 2nd drawing shows the PCB thickness limitation. The component side height is 2.8mm, and the solder side maximum height is 3.00mm and the PCB thickness is 1.00mm.
The 3rd drawing shows allied mechanical data of SOM-A2558 series board and CSB. Users could see that the matting height is 3.00mm and the solder side maximum height of SOM-A2558 is also 3.00mm. So, Advantech don’t suggest users to place any components between SOM module and CSB in layout stage. It could be short!
Most users will question the height of SOM structure product. Does product be too thick based on SOM structure product? User could see the
