SiS SOM-ETX Module with CPU, Audio, VGA/LCD, LVDS and Ethernet SOM-4451 SODIMM socket Flash BIOS SiS 552 Introduction Advantech's new SOM-4451 is a SOM-ETX CPU module board True multimedia SOM-ETX SOM-4451 integrates Ultra-AGP with an on-board, embedded low power 200 MHz SiS 552 technology to deliver high performance GUI-memory bandwidth. processor. Other on-board features include a VGA/LCD Furthermore, SiS552 provides powerful slice layer decoding DVD controller with 18-bit LCD TFT display and 10/100 Mbps PCI accelerator to improve the DVD playback performance. In addition Ethernet interface. A SOM-ETX is provided, with PCI/ISA/ to providing the standard interface for CRT monitors, SOM-4451 Audio/VGA&LCD and also optional SSD support for DOC. 62- also provides a Digital Flat Panel Port(DFP), and also supports level watchdog timer and jumperless on-line setup is also NTSC/PAL Video Output. SOM-4451 also adopts Share System supported. Memory Architecture that can flexibly utilize the frame buffer size up to 128MB. SOM-ETX with SiS 552 Processor Available Now With this board, system engineers will now be able to upgrade Features their 486-based systems to 586 level without worries, because  On-board 200 MHz SiS 552 processor (fanless) a pentium level SiS 552 processor is mounted directly on  On-board VGA/LCD display controller and 18-bit LCD TFT board. Mounting CPUs directly on board eases the display configuration and installation process because there is no need to set any jumpers for speed or voltage differences between  62-level watchdog timer, jumperless on-line setup various CPUs. In addition to ease of configuration, the SiS 552 supported 200 MHz low-power CPU has been specially designed to work  Supports wake on LAN, wake on ring (modem) ° well in environments with temperatures of up to 60 C without  SSD support for DOC TSOP1 (optional) need of a fan. Eliminating the CPU fan from a system significantly reduces MTBF worries and increases application  Supports CMOS data backup functions possibilities. www.advantech.com/som SOM-4451 Specifications Ethernet Interface  CPU: Embedded low power SiS 552 200 MHz processor (provides fanless operation)  RealTek™ RTL 8139 -Ethernet interface: IEEE 802.3u 100BASE-T Fast Ethernet  BIOS: Award 256KB Flash memory compatible  Chipset: SiS 552 (on-chip) -Built-in boot ROM  System memory: One SDRAM SODIMM socket, max up to 512 MB Audio Function  Enhanced IDE interface: One Enhanced IDE interface that  Chipset: SiS552 supports 2 IDE devices PIO mode 3,4 UDMA33 transfer.
