Chapter 1 Introduction

1.1 Introduction

The SOM-4486 is an Intel Ultra Low Voltage Intel® Celeron® M proces- sor System On Module (SOM) with audio controller, a 4X AGP SVGA controller, a PCI 10/100Base-T Ethernet interface. Using an Intel ULV Celeron® M processor, the SOM-4486 achieves quite good performance on the SOM-ETX CPU module. On-board features include two serial ports, one multi-mode parallel (ECP/EPP/SPP) port, four USB (Universal Serial Bus) ports, a floppy drive controller, and a keyboard/PS/2 mouse interface. The built-in high-speed PCI IDE controller supports both PIO and UDMA/66 bus master modes. Up to two IDE devices can be con- nected, including large hard disks, CD-ROM drives, and tape backup drives. The SOM-4486 features power management to minimize power consumption. It complies with the "Green Function" standard and sup- ports Doze, Standby and Suspend modes. In addition, the board's watch- dog timer can automatically reset the system or generate an interrupt if the system stops due to a program bug or EMI.The small size (95 mm x 114 mm) and use of four high capacity connectors based on the proven SOM-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.

The SOM-4486 is a highly integrated multimedia SOM that combines audio, video, and network functions. It provides 16-bit half-duplex, 8-bit full-duplex, integrated 3D audio, and up to 1024 x 768 resolution @ 16.8 M colors with 8/16/32 MB system memory. Major on-board devices adopt PCI technology, to achieve outstanding computing performance and 10W power consumption when used with Intel® Celeron® M pro- cessors.
