1 Introduction
COM Express™ Concept
COM Express™ is an open industry standard defined specifically for COMs (computer on modules). Its creation makes it possible to smoothly
transition from legacy interfaces to the newest technologies available today. COM Express™ modules are available in following form factors:
•Mini 84mm x 55mm
•Compact 95mm x 95mm
•Basic 125mm x 95mm
•Extended 155mm x110mm
The COM Express™ specification 2.1 defines seven different pinout types.
Types Connector Rows PCI Express Lanes PCI IDE Channels LAN ports USB 2.0/ USB 3.0 Display Interfaces
Type 1 A-B Up to 6 1 8 / 0 VGA, LVDS
Type 2 A-B C-D Up to 22 32 bit 1 1 8 / 0 VGA, LVDS,PEG/SDVO
Type 3 A-B C-D Up to 22 32 bit 3 8 / 0 VGA,LVDS,PEG/SDVO
Type 4 A-B C-D Up to 32 1 1 8 / 0 VGA,LVDS,PEG/SDVO
Type 5 A-B C-D Up to 32 3 8 / 0 VGA,LVDS,PEG/SDVO
Type 6 A-B C-D Up to 24 1 8 / 4 VGA,LVDS,PEG, 3x DDI
Type 10 A-B Up to 4 1 8 / 0 1x DDI
The conga-TCA modules use the Type 6 pinout definition and comply with COM Express 2.1 specification. They are equipped with two high
performance connectors that ensure stable data throughput.
The COM integrates all the core components and is mounted onto an application specific carrier board. COM modules are 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 6 pinout provides the ability to offer PCI Express, Serial 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 use 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 specific 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.

2.5 Power Consumption
The power consumption values listed in this document were measured under a controlled environment. The hardware used for testing includes
a conga-TCA module, conga-Cdebug carrier board, CRT monitor, SATA drive, and USB keyboard. The conga-Cdebug is modified so that
the 12V input is only routed to the module and all other circuity on the carrier itself is powered by the 5V input. The SATA drive was powered
externally by an ATX power supply so that it does not influence the power consumption value that is measured for the module. The USB
keyboard was detached once the module was configured within the OS. All recorded values were averaged over a 30 second time period.
Cooling of the module was done by the module specific heatspreader and a fan cooled heatsink to measure the power consumption under
normal thermal conditions.
The conga-Cdebug originally does not provide 5V standby power. Therefore, an extra 5V_SB connection without any external loads was made.
Using this setup, the power consumption of the module in S3 (Standby) mode was measured directly.
Each module was measured while running Windows 7 Professional 32Bit, Hyper Threading enabled, Speed Step enabled and Power Plan set to
“Power Saver”. This setting ensures that Core™ processors run in LFM (lowest frequency mode) with minimal core voltage during desktop idle.
Each module was tested while using a 1GB memory modules. Using different sizes of RAM will cause slight variances in the measured results.
To measure the worst case power consumption the cooling solution was removed and the CPU core temperature was allowed to run up to
between 95° and 100°C while running 100% workload with the Power Plan set to “Balanced”. The peak current value was then recorded. This
value should be taken into consideration when designing the system’s power supply to ensure that the power supply is sufficient during worst
case scenarios.
Power consumption values were recorded during the following stages:
Windows 7 (32 bit)
•Desktop Idle (power plan = Power Saver)
•100% CPU workload (see note below, power plan = Power Saver)
•100% CPU workload at approximately 100°C peak power consumption (power plan = Balanced)
•Suspend to RAM. Supply power for S3 mode is 5V.
Note
A software tool was used to stress the CPU to maximum frequency.

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.

2.6.1 CMOS Battery Power Consumption
RTC @ 20ºC Voltage Current

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 specific 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.
2.7 Environmental Specifications
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 congatec heatspreader, the maximum operating
temperature refers to any measurable spot on the heatspreader’s surface.
Humidity specifications are for non-condensing conditions.

4 Heatspreader
The heatspreader is thermally coupled to the CPU via a thermal gap filler and on some modules it may also be thermally coupled to other heat
generating components with the use of additional thermal gap fillers. 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 as a thermal interface between the
module and the application specific thermal solution.
The application specific 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 thereby using the whole chassis as a heat
dissipater.
For additional information about the conga-TCA heatspreader, refer to section 4.1 of this document.
Caution
The congatec heatspreaders/cooling solutions are tested only within the commercial temperature range of 0° to 60°C. Therefore, if your
application that features a congatec heatspreader/cooling solution operates outside this temperature range, ensure the correct operating
temperature of the module is maintained at all times. This may require additional cooling components for your final application’s thermal
solution.
For adequate heat dissipation, use the mounting holes on the cooling solution to attach it to the module. Apply thread-locking fluid on the
screws if the cooling solution is used in a high shock and/or vibration environment. To prevent the standoff from stripping or cross-threading,
use non-threaded carrier board standoffs to mount threaded cooling solutions.
For applications that require vertically-mounted cooling solution, use only coolers that secure the thermal stacks with fixing post. Without the
fixing post feature, the thermal stacks may move.
Also, do not exceed the maximum torque specified for the cooling solution screws. Doing so may damage the module or/and the carrier
board.
Caution
Provide active airflow for the cooling fins of the conga-TCA/CSP-T(B) when you use the cooler on variants with PN: 047003 or PN: 047004.
The cooler cannot dissipate the heat generated by these modules without an active airflow.
