2.1 Introduction
SECOMX-945/N270 is a CPU module, in XTX
™
format, based on Intel
®
Atom
™
CPU interfaced to
Intel
®
945GME Chipset, that provide most of its standard functionalities.
CPU used on SECOMX-945/N270 module is Intel
®
Atom
™
N270 at 1.6 GHz, with 512KB L2
Cache, 533 MHz FSB and Hyper Threading (HT) capabilities. TDP (Thermal Dissipation Power) is
2.5 W.
Intel
®
945GME chipset provides the access to memory, which is available as a single SODIMM
DDR2 memory module, with a capacity up to 2GB. SODIMM memory modules supported can have
frequencies of 533 or 667MHz.
It also integrates Intel
®
Graphics Media Accelerator 950, that offers an advanced 2D and 3D
graphic engine, and can pilot directly Flat Panels through LVDS interface, standard CRT with RGB
interface, and TV using S-Video or Composite signals.
Many other features come through Southbridge Intel
®
NH82801GHM (ICH7-M DH), that provides 6
USB 2.0 ports, AC’97 or HD audio interface, PCI Bus, up to four PCI Express x1 ports, one IDE
Channel, two S-ATA channels, LAN interface and LPC bus.
Using these interfaces, there are also other controllers on board, that complete the features of
SECOMX-945/N270 board with two RS-232 ports (at TTL level), one parallel port (optionally
configurable as a Floppy Disk port), PS/2 port for mouse and keyboard, a secondary IDE channel,
Real Time Clock and Watch Dog Timer.
Six mounting holes on the board provide secure mounting to allow the module increased shock
and vibration resistance.
Please refer to following chapter for a complete list of all peripherals integrated and characteristics.
As described in XTX
™
specifications, all interfacing signals (except SO-DIMM memory socket, that
is directly on XTX
™
module), are carried out on four 100-pin low profile standard connectors.
Therefore, for external interfacing to standard devices, a carrier board is needed. This board will
implement all the routing of the interface signals to external standard connectors, as well as
integration of other peripherals/devices not already included in SECOMX-945/N270 CPU module.
The carrier board can be designed exactly as needed, both in mechanical dimensions and in
connectors / interfaces desired, and allows the maximum flexibility possible, since the CPU module
can be changed at any moment without lack of compatibility or needing of a new design of the
carrier board.
