2 Reference Manual CoreModule 745
Chapter 2 Product Overview
This introduction presents general information about the PC/104 architecture and the CoreModule 745
Single Board Computer (SBC). After reading this chapter you should understand:
• PC/104 architecture
• Product description
• CoreModule 745 features
• Major components (ICs)
• Headers and Connectors
• Specifications
PC/104 Architecture
The PC/104 architecture affords a great deal of flexibility in system design. You can build a simple system
using only a CoreModule 745 SBC, input/output devices connected to the serial, USB, or SATA ports, and
the on-board Solid State Disk storage device. To expand a simple CoreModule system, simply add selfstacking PC/104 and PC/104-Plus expansion boards to provide additional capabilities, such as:
• Additional serial and parallel ports
• Analog or high-speed digital I/O
Data Acquisition (Analog In/Out)
USB 2.0 expansion modules
IEEE 1394 (FireWire) expansion modules
Standard VGA video output
PC/104 or PC/104-Plus expansion modules can be stacked with the CoreModule 745 avoiding the need for
large, expensive card cages and backplanes. The PC/104-Plus expansion modules can be mounted directly to
the PC/104 and PC/104-Plus connectors of the CoreModule 745. PC/104-compliant modules can be stacked
with an inter-board spacing of ~0.6 inches, so that a 3-module system fits in a 3.6" x 3.8" x 2.4" space. See
Figure 2-1.
One or more MiniModule products or other PC/104 modules can be installed on the CoreModule expansion
connectors, so that the expansion modules fit within the CoreModule outline dimensions. Most MiniModule
products have stackthrough connectors compatible with the PC/104-Plus Version 2.0 specification. Several
modules can be stacked on the CoreModule headers. Each additional module increases the thickness of the
package by ~17mm (0.66"). See Figure 2-1.

Product Description
The CoreModule 745 SBC is an exceptionally high integration, high performance, Intel Atom™ N455 or
D525 processor based system, compatible with the PC/104 standard. This rugged and high quality singleboard system contains all the component subsystems of an ATX motherboard plus the equivalent of several
PCI expansion boards.
The Intel Atom N400 and D500 series CPUs integrate processor cores with Graphics and Memory Hubs
(GMHs), providing low-power, high-performance processors, memory controllers for up to 2GB DDR3
memory, and graphics controllers which provide LVDS and VGA signals for most LCD video panels and
CRT monitors.
The ICH8-M chipset provides controllers for the I/O Hub (Southbridge) featuring four USB ports, two
SATA ports, one Ultra DMA 33/66/100 IDE port supporting two IDE devices, one SMBus port, one SPI
port, one GPIO port, one PCIe bus for Gigabit Ethernet, and one PCI bus for PC/104 and PC/104-plus
devices. The CoreModule 745 provides legacy interfaces through the SMSC SCH3112I-NU Super I/O
featuring three serial ports and a PS/2 keyboard and mouse port.
The CoreModule 745 can be expanded through the PCI expansion bus using the PC/104 and PC/104-Plus
connectors for additional system functions. This bus offers compact, self-stacking, modular expandability.
The PC/104 bus is an embedded system version of the signal set provided on a desktop PC’s ISA bus. The
PC/104-Plus bus includes this signal set plus additional signals implementing a PCI bus, available on a
120-pin (4 rows of 30 pins) PCI expansion bus connector. This PCI bus operates at a clock speed of 33MHz.
The CoreModule 745 is particularly well suited to either embedded or portable applications and meets the
size, power consumption, temperature range, quality, and reliability demands of embedded system
applications. It can be stacked with ADLINK MiniModules™ or other PC/104-compliant expansion
modules, or it can be used as a powerful computing engine. The CoreModule 745 requires a single +5V AT
power source.

NOTE The pinout tables in Chapter 3 of this manual identify pin sequence using the
following method: A 30-pin header with two rows of pins, using odd/even
numbering, where pin 2 is directly across from pin 1, is noted as 30-pin, 2 rows, odd/
even (1, 2) sequence. The second number in the parenthesis is always directly across
from pin 1. See Figure 2-5.
