SOM-4461 A2 Version User Manual 2
1.1 Introduction
SOM-4461 is an embedded ETX 3.0 CPU module. The new CPU module supports
Intel
®
N270 1.6 GHz processor with Intel
®
945GSE and ICH7M chipsets. SOM-4461
has an integrated graphic engine: Intel
®
GMA950 and Microsoft
®
DirectX 9.1. In a
basic form factor of 114 mm x 95 mm, SOM-4461 provides scalable high perfor-
mance with lower power consumption, and is an easy to integrate solution for appli-
cations utilizing a plug-in CPU module on an application-specific customer solution
board.
SOM-4461 with advanced I/O capacity incorporates serial differential signaling tech-
nologies such as 36/48-bit LVDS, VGA,TV out, AC97 audio, 10/100 LAN, PCI Mas-
ters x 4, SATA x 2 ports, USB 2.0 x 4 ports, 1 EIDE, 2 serial ports, FDD/LPT port.
SOM-4461 offers design partners more choices for their own applications needing
lower power consumption while maintaining a compact form factor.
SOM-4461 complies with the "Green Function" standard and supports Idle, Standby
and Suspend modes. The small size (114 mm x 95 mm) and use of four high capacity
connectors based on the proven ETX 3.0 form factor, allows the CPU module to be
easily and securely mounted onto a customized solution board or our standard SOM-
DB4400/DB4700 development board.
The SOM-4461 is a highly integrated multimedia COM that combines audio, video,
and network functions. It provides dual channel 18/24-bit LVDS interface for small/
middle size TFT LCD displays, DDR2 memory up to 2 GB, audio interface (AC97).
Major on-board devices adopt PCI technology, to achieve computing performance
when customer adopts SOM-4461 to establish their own application.
In order to comply with increasing demand for 36/48-bit panel from our customers
world wide, we decided to refine our outstanding SOM-4461 and generated an SOM-
4461 A2 version, which provides 36/48-bit LVDS interface and Realtek 8103EL LAN
support. Customers can now enjoy the benefits already in A1 version and renewed
functions in A2 version.
