General Information
This chapter gives background information on the SOM-4455 CPU System
On Module.
Sections include:
• Introduction
• Specifications
• Board Dimensions
Chapter 1 Introduction
Advantech's SOM-ETX form factor System On Module provides a scalable solution that meets customers' advanced CPU and application development needs. The SOM-4455 incorporates a low power, fanless AMD
Geode LX800-500 MHz processor that has become the embedded integrators' processor of choice. It uses a AMD CS5536 chipset as its VGA/
LCD controller, with single 18 bit LVDS interface and 64-bit graphics engine. The CS5536 display controller (LCD and CRT display support) allows sharp and clear LCD screen resolutions up to 1024 x 768 and CRT resolutions up to 1600 x 1200 @ 16bpp colors. Combined with the
CS5536 system chipset is a Intel® 82551ER Ethernet chipset. It supports all functions of an AT-compatible industrial computer. There is one DDR
SODIMM socket that supports up to 1 GB DDR SDRAM. The small size
(95 mm x 114 mm) and use of four high capacity connectors based on the proven ETX form factor, allow the SOM-ETX modules to be easily and securely mounted onto a customized solution board or our standard
SOM-DB4400 development board.
Many gains were made by using the AMD Geode LX processor. The LX processor provides the lowest power consumption combined with high speed processing power. This processor also supports most popular web plug-ins and leverages existing software and hardware investments.
Onboard features include an ethernet interface, socket for Compact-
Flash™ card, Enhanced IDE interface capable of Ultra DMA transfer protocol, four USB2.0 ports, one parallel port, two serial ports and a PS/2 keyboard/mouse interface.

Software Configuration
This chapter details the software configuration information. It shows you how to configure the SOM-4455 card to match your application requirements.
Sections Include:
• LCD display configuration
• Connections for two standard LCDs
Chapter 3 Software Configuration
3.1 Introduction
The SOM-4455 system BIOS and custom drivers are located in a 256 KB,
32-pin Flash ROM device, designated U1. A single Flash chip holds the system BIOS and VGA BIOS. The display type can be configured via software. This method minimizes the number of chips and eases configuration. You can change the display BIOS simply by reprogramming the
Flash chip.
3.2 Utility CD disk
The SOM-4455 is supplied with a software utility on CD-ROM. This disk contains the necessary file for setting up the VGA display. Directories and files on the disk are as follows:
AWDFLASH.EXE
4455Vxxx.BIN
Figure 3.1: Contents of SOM-4455 utility disk
AWDFLASH.EXE
This program allows you to update the BIOS Flash ROM.
4455Vxxx.BIN
This binary file contains the system BIOS.
3.3 VGA display software configuration
The SOM-4455 onboard VGA/LCD interface supports an 18-bit TFT
LCD, flat panel displays and traditional analog CRT monitors. The interface can drive CRT displays with resolutions up to 1024 x 768 in 32bpp.
It is also capable of driving color panel displays with resolutions of 1600 x 1200 in 16 bpp. The LCD type is configured completely via the software utility, so you do not have to set any jumpers. Configure the LCD type as follows:
SOM-4455 User Manual 10
1. Apply power to the SOM-4455 application with a color TFT display attached. This is the default setting for the SOM-4455 series. Make sure that the AWDFLASH.EXE and *.BIN files are located in the working drive.
Note: Make sure that you do not run AWDFLASH.EXE while your system is operating in EMM386 mode.
2. At the prompt, type AWDFLASH.EXE and press <Enter>. The
VGA configuration program will then display the following:
Figure 3.2: BIOS VGA setup screen
3. At the prompt, type in the BIN file which supports your display.
When you are sure that you have entered the file name correctly press
<Enter>. The screen will ask “Do you want to save?” If you wish to continue press Y. If you change your mind or have made a mistake press N.
4. If you decide to continue, the screen will issue a prompt which will then ask “Are you sure to program (Y/N)?” If you wish to continue, press
Y. Press N to exit the program.
The new VGA configuration will then write to the ROM BIOS chip. This configuration will remain the same until you run the AWDFLASH.EXE program and change the settings.

LVDS Connection
This appendix contains information concerning the LVDS installation and pin assignments.
Appendix C LVDS Connection
C.1 LVDS Introduction
When you mention the impressive data rate of 400 Mbps at 15 meters for
LVDS, you immediately realize how significant the differences are between analog and digital interfaces. There are several other factors other than significantly increased data transfer rate and image quality that make LVDS (Low-Voltage Differential Signaling) very attractive to industrial users. One is that LVDS drivers and receivers maintain excellent signal levels and performance while operating on supply voltages as low as 2 V. This low voltage allows LVDS to operate independently from the main power supply voltage. Another factor is that LVDS drivers and receivers have a low swing voltage. This voltage is typically around 345 mV. This allows LVDS devices to achieve high speeds while using relatively little power. This low differential swing voltage together with selfcanceling EMI, reduces EMI problems significantly. This is especially important in space- critical applications. This is also why LVDS has already been widely used in Notebook computer panel connections.
All Digital Benefits
No matter which digital standard an end user uses for their industrial applications, it will have to provide the following criteria: Be compatible so that system and display products from different suppliers can be made available in an open market. Become a standard for the electronics and
PC industry. Be able to transmit data over standard twisted pair cables as well as fiber optic. Maintain a low bit error rate for high quality images while operating at very low power levels, and finally, be scalable.
