1.1 Introduction
Figure 1-1: 3308490
The 3308490 is a PCISA CPU card with an embedded 45 nm Intel® Atom™
processor. The embedded Intel® Atom™ N270 processor has a 1.60 GHz clock speed,
533 MHz FSB and 512 KB of L2 cache.
The 3308490 includes four graphics outputs. VGA on the rear panel provides basic
output capabilities for use with most monitors. Internally, an LVDS header provides a
connection to LCD displays for integrating the 3308490 into a system with built-in
monitor. The TV header provides output to a standard TV or HDTV through the optional
adapter cables, which provide a single cable connection on a card slot and a cable
splitting the signal into the component parts. Finally, an SDVO connector provides a direct
connection from the Northbridge SDVO port to an GAI SDVO graphics card.
512 MB of DDR2 memory is included with the 3308490 (a custom option with a
DDR2 SO-DIMM slot is available). Permanent storage is provided through dual SATA
ports, offering 300 MB/s transfer speeds, RAID 0 and RAID 1 support. Legacy IDE
connectivity is available through an IDE port, and through a CompactFlash® card located
on the solder side of the 3308490.
Other connectors on the 3308490 include six USB ports (two external, four internal),
an RS-232 port, an RS-232/422/485 port, LPT and digital I/O. An HD Audio connector
connects to an external audio kit, providing HD audio or AC’97 audio capabilities with the
appropriate audio kit.
