Chapter 1 SOM-A2552series Architecture
1.1 Introduction
The SOM-A2552is WinCE ready, compact size module platform with
SBC-function-level functionality that is emphasis at high performance VGA
capability that offers Ultra low power consumption with SXGA LCD, Dual
Display, Analogy VGA in/out put, Audio Interface into a compact 68x68x6.8mm
size module.
By the integration of Intel PXA-255 32-bit SoC and SMI SM-501 VGA
controller, SOM-A2552 is perfect for Multimedia, mobility, battery powered,
great heavy display base embedded Internet appliance or so called smart
embedded devices.
SOM-A2552series Design highlight:
-WinCE.NET-ready platform as functional system engine
-SoC Intel XScale PXA255 & Companion Graphic Chip SMI SM501provide
complete SBC functionality & high performance Graphic function in a
module
-Pre-define I/O Ready bus thru SODIMM-200 interface
-Design-in package: Reference kit with full design-in documentation
-Advantech RISC WinCE builder offers friendly application migration
interface
-Low profit 68x68mm
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 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-A2552benefit
The SOM-A2552series are very compact (68mm x 68mm x 6.8mm) and
highly integrated system module. SOM-A2552series 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-A2552 series include popular & common peripheral functions such
as serial ports, USB, 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-A2552 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-A2552 solution also insures against obsolescence
as computer technology continues to evolve. A properly designed SOM-A2552
CSB can be used with several successive generations of SOM-A2552
modules. An SOM-A2552 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-A2552 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-A2552 series is designed for
lWireless broadband terminals: Wireless access to video/TV/DVD/PVR,
wireless access to broadband connection, digital picture viewer, remote
access to Internet/email, remote control of AV functions

site for more.
System Memory
SOM-A2552 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-A2552 series. One is Boot Flash,
the other is Storage Flash.
Boot Flash is 1MB NOR flash. In standard SOM-A2552 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-A2552 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-A2552 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.
