Introduction

Introduction

The Graphics ClientM (GCM) is a low-power single-board computer based on the

Marvell® PXA320 processor. The PXA320 processor integrates scalable general-

purpose processing, 2D graphics acceleration, and wireless technology to provide

hardware-accelerated graphics display and high-powered computing capabilities. The

GCM is ideal for running graphics-intensive applications, especially those requiring

wireless connectivity, and is targeted towards hand-held, medical, fleet management, and

embedded markets.

In addition to industry-standard interfaces, the GCM includes the ADSmartIO™. The

ADSmartIO extends GCM capabilities by providing a wide array of customizable

functions and I/O.

This manual provides details about the various features of the GCM and about how they

create a system that meets your application needs. It is intended for embedded system

integrators and software application developers. Design details apply to the revision listed

in Appendix C – Board Revision, page 57.

Block Diagram

The following diagram illustrates the system organization of the GCM. The functionalities

shown with dotted lines or labelled as optional are available as volume production

options. The following sections provide further details about these various options.

Handling Your Board Safely

Anti-Static Handling

The GCM contains CMOS devices that could be damaged by electrostatic discharge

(ESD). Observe industry-standard electronic handling procedures when handling the

board. Where possible, work on a grounded anti-static mat. At a minimum, touch an

electrically grounded object before handling the board or touching any components on

the board.

Packaging

Please ensure that, should a board need to be returned to Eurotech, it is adequately

packed, preferably in the original packing material.

Electromagnetic Compatibility

The GCM is classified as a component with regard to the European Community

Electromagnetic Compatibility (EMC) regulations. Because Eurotech supplies only the

single-board computer and not fully integrated systems, Eurotech cannot provide

meaningful system-level emissions test results. It is the responsibility of the user to

ensure that systems using the GCM are compliant with the appropriate EMC standards.

RoHS Compliance

The European RoHS Directive (Restriction on the use of certain Hazardous Substances –

Directive 2002/95/development system) limits the amount of six specific substances

within the composition of the product. The GCM fully complies with the RoHS directive.

A full RoHS Compliance Materials Declaration Form for the GCM is included as Appendix

B – RoHS Compliance, page 56. Further information regarding RoHS compliance is

available on the Eurotech web site at www.eurotech.com.
