SOM-4430 User Manual 2
1.1 Introduction
SOM-4430 is an embedded CPU module that fully complies with the SOM-ETX form
factor standard. The new CPU module supports Advantech EVA-X4300 SOC (sys-
tem on chip) which supports PCI and ISA interfaces. In a basic form factor of 95 mm
x 114 mm, the SOM-4430 provides a scalable cost effective and easy to integrate
solution for customers’ applications by utilizing a plug-in CPU module on an applica-
tion-specific customer solution board. The SOM-4430 with advanced I/O capacity
incorporates PCI, ISA, IDE, USB 2.0, and TTL LCD interfaces. SOM-4430 offers
design partners more choices for their own applications needing cost effective solu-
tion while maintaining a compact form factor.
The small size (95 mm x 114 mm) and use of four high capacity connectors based on
the proven SOM-ETX form factor, allows SOM-ETX modules to be easily and
securely mounted onto a customized solution board or our standard SOM-DB4400
development board.
