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:

l68 mm x 68 mm x 6.8 mm compact size module

lPower management ready support with Normal, Idle, Suspend,

Off mode utilities.

lOS-ready package for Windows CE .NET/Linux Installation

(Windows CE .NET 4.2 BSP ready)

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

Ethernet, USB Host and PCI I/F support

lBoot option by onboard Flash or CFC makes easy maintenance

and cost savings

lProvide a variety of reconfi guration options to fulfi ll specifi c

requirements

lDesign-in Kit package is available for complete design-in support

lOptional 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.

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.

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

lSOM-A255Fseries: 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:

lSystem memory assignments

lI/O control

lRTC 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.
