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:

l 68 mm x 68 mm x 6.8 mm compact size module
l Power management ready support with Normal, Idle, Suspend,

Off mode utilities.

l OS-ready package for Windows CE .NET/Linux Installation

(Windows CE .NET 4.2 BSP ready)

l Local bus(AMI Bus), comprehensive I/O interfaces as PS/2 port,

Ethernet, USB Host and PCI I/F support

l Boot option by onboard Flash or CFC makes easy maintenance

and cost savings

l Provide a variety of reconfi guration options to fulfi ll specifi c

requirements

l Design-in Kit package is available for complete design-in support
l 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.

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.

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:

l System memory assignments

l I/O control

l 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
