COM Express™ Concept
COM Express™ is an open industry standard dened specically for COMs (computer on modules). It’s creation provides the ability to make a
smooth transition from legacy parallel interfaces to the newest technologies based on serial buses available today. COM Express™ modules
are available in following form factors:
• Compact 95mm x 95mm
• Basic 125mm x 95mm
• Extended 155mm x 110mm

Copyright © 2008 congatec AG B915m10 7/92
The COM Express™ specication 1.0 denes ve different pinout types.
Types Connector Rows PCI Express Lanes PCI IDE Channels LAN ports
Type 1 A-B Up to 6 1
Type 2 A-B C-D Up to 22 32 bit 1 1
Type 3 A-B C-D Up to 22 32 bit 3
Type 4 A-B C-D Up to 32 1 1
Type 5 A-B C-D Up to 32 3
congatec AG modules utilize the Type 2 pinout denition. They are equipped with two high performance connectors that ensure stable data
throughput.
The COM (computer on module) integrates all the core components and is mounted onto an application specic carrier board. COM modules
are a legacy-free design (no Super I/O, PS/2 keyboard and mouse) and provide most of the functional requirements for any application. These
functions include, but are not limited to, a rich complement of contemporary high bandwidth serial interfaces such as PCI Express, Serial ATA,
USB 2.0, and Gigabit Ethernet. The Type 2 pinout provides the ability to offer 32-bit PCI, Parallel ATA, and LPC options thereby expanding
the range of potential peripherals. The robust thermal and mechanical concept, combined with extended power-management capabilities, is
perfectly suited for all applications.
Carrier board designers can utilize as little or as many of the I/O interfaces as deemed necessary. The carrier board can therefore provide all
the interface connectors required to attach the system to the application specic peripherals. This versatility allows the designer to create a
dense and optimized package, which results in a more reliable product while simplifying system integration. Most importantly, COM Express™
modules are scalable, which means once an application has been created there is the ability to diversify the product range through the use of
different performance class or form factor size modules. Simply unplug one module and replace it with another, no redesign is necessary.
Certication
congatec AG is certied to DIN EN ISO 9001:2000 standard.

Power Consumption1.5
The power consumption values listed in this document were measured under a controlled environment. The hardware used includes a conga-B915
module, conga-CEVAL and conga-Cdebug carrier boards, CRT monitor, SATA drive, and USB keyboard. When using the conga-Cdebug, the
SATA drive was powered externally by an ATX power supply so that it does not inuence the power consumption value that is measured for
the module. The USB keyboard was detached once the module was congured within the OS. The module was rst inserted into the conga-
Cdebug, which was powered by a Direct Current (DC) power supply set to output 12V. The current consumption value displayed by the DC
power supply’s readout is the value that is recorded as the power consumption measurement for Desktop Idle, 100% Workload and Standby
modes. The power consumption of the conga-Cdebug (without module attached) was measured and this value was later subtracted from the
overall power consumption value measured when the module and all peripherals were connected. All recorded values are approximate.
The conga-Cdebug does not provide 5V Standby power therefore S3 mode was measured using the conga-CEVAL powered by an ATX power
supply with a multimeter attached to the 5V Standby power line. The 5V Standby power consumption of the conga-CEVAL (without module
attached) and all peripherals connected was rst measured and the resulting value was later subtracted from the overall S3 power consumption
value measured when the module was attached. All S3 recorded values are approximate.
Each module was measured while running Windows XP Professional with SP2 (service pack 2) and the “Power Scheme” was set to “Portable/
Laptop”. This setting ensures that Core 2 Duo and Core Duo processors run in LFM (lowest frequency mode) with minimal core voltage during
desktop idle. Celeron M processors do not support this feature and therefore always run at the same core voltage even during desktop idle.
Each module was tested while using a swissbit® DDR2 PC2-4200-444 512MB memory module. Using different sizes of RAM, as well as two
memory modules, will cause slight variances in the measured results.
Power consumption values were recorded during the following stages:
Windows XP Professional SP2
Desktop Idle•
100% CPU workload (see note below)•

Note
All recorded power consumption values are approximate and only valid for the controlled environment described earlier. 100% workload refers
to the CPU workload and not the maximum workload of the complete module. Supply power for S3 mode is 5V while all other measured modes
are supplied with 12V power. Power consumption results will vary depending on the workload of other components such as graphics engine,
memory, etc.

The CMOS battery power consumption value listed above should not be used to calculate CMOS battery lifetime. You should measure the
CMOS battery power consumption in your customer specic application in worst case conditions, for example during high temperature and
high battery voltage. The self-discharge of the battery must also be considered when determining CMOS battery lifetime. For more information
about calculating CMOS battery lifetime refer to application note AN9_RTC_Battery_Lifetime.pdf, which can be found on the congatec AG
website at www.congatec.com.
Environmental Specications1.7
Temperature Operation: 0° to 60°C Storage: -20° to +80°C
Humidity Operation: 10% to 90% Storage: 5% to 95%
Caution
The above operating temperatures must be strictly adhered to at all times. When using a heatspreader the maximum operating temperature
refers to any measurable spot on the heatspreader’s surface.
congatec AG strongly recommends that you use the appropriate congatec module heatspreader as a thermal interface between the module
and your application specic cooling solution.
If for some reason it is not possible to use the appropriate congatec module heatspreader, then it is the responsibility of the operator to ensure
that all components found on the module operate within the component manufacturer’s specied temperature range.
For more information about operating a congatec module without heatspreader contact congatec technical support.
Humidity specications are for non-condensing conditions.

Heatspreader3
An important factor for each system integration is the thermal design. The heatspreader acts as a thermal coupling device to the module. It
is a 3mm thick aluminum plate.
The heatspreader is thermally coupled to the CPU via a thermal gap ller and on some modules it may also be thermally coupled to other heat
generating components with the use of additional thermal gap llers.
Although the heatspreader is the thermal interface where most of the heat generated by the module is dissipated, it is not to be considered
as a heatsink. It has been designed to be used as a thermal interface between the module and the application specic thermal solution. The
application specic thermal solution may use heatsinks with fans, and/or heat pipes, which can be attached to the heatspreader. Some thermal
solutions may also require that the heatspreader is attached directly to the systems chassis therefore using the whole chassis as a heat
dissipater.
Caution
There are 4 mounting holes on the heatspreader designed to attach the heatspreader to the module. These mounting holes must be used to
ensure that all components that are required to make contact with heatspreader do so. Failure to utilize the these mounting holes will result in
improper contact between these components and heatspreader thereby reducing heat dissipation efciency.
Attention must be given to the mounting solution used to mount the heatspreader and module into the system chassis. Do not use a threaded
heatspreader together with threaded carrier board standoffs. The combination of the two threads may be staggered, which could lead to
stripping or cross-threading of the threads in either the standoffs of the heatspreader or carrier board.
