4 Cooling Solution
The conga-PA3 SBC offers Ultra Low Power boards with high computing performance and outstanding graphics. Due to its low power consumption, the SBC generates less heat and therefore requires less active cooling, allowing the use of quieter, lower profile coolers that are better suited to small form factor systems.
Nonetheless, all electronics contain semiconductor devices which have operating temperature ranges that should be adhered to. This means that for reliable operation, the thermal design of the conga-PA3 must be carefully considered. For this reason, it is imperative to provide sufficient air flow to each of the components, to ensure the specified operating temperature of the conga-PA3 is maintained. congatec AG offers two cooling solutions for the conga-PA3:
• A congatec passive cooling solution (CSP).
• A congatec heatspreader. The heatspreader features a Gap Pad, heatstack and a Hi-Flow 225UT pressure sensitive, phase change thermal interface.
Passive Cooling Solution Heatspreader
Note
You can also use a custom cooling solution for the conga-PA3. When a passive cooling is used, the end user must ensure that adequate air flow is maintained.
See section 1.2.2 “Optional Accessories/Cables” for the part numbers of the cooling accessories. For the dimensions of the CSP and heatspreader, see sections 4.1 and 4.2.
Caution
The congatec heatspreader is only suitable for use within commercial temperature ranges (0 o
C to 60 o
C) . It is not designed to be used within industrial temperature ranges (-40 o
C to 85 o
C). When using a heatspreader with conga-PA3 commercial grade variants, the maximum operating temperature refers to any measurable spot on the heatspreader’s surface.
14/44
4.1
congatec AG strongly recommends that you use the appropriate congatec heatspreader on the conga-PA3 and within operating temperatures of 0 o C to 60 o C. If you use heatspreaders that are not specified for the conga-PA3 or use the conga-PA3 industrial variants, then it is your responsibility to ensure that all components found on the module operate within the component manufacturer’s specified temperature range.
Humidity specifications are for non-condensing conditions.

The cBC fully isolates some of the embedded features such as system monitoring, I²C bus from the x86 core architecture. This improves performance and reliability, even during low power mode.
6.2.1 Fan Control
The congatec Board Controller on the conga-PA3 controls the power supplied to the fan with the PWM signal. Additionally, there is an input signal called FAN_TACHOIN that provides the ability to monitor the system’s fan RPMs (revolutions per minute). This signal must receive two pulses per revolution in order to produce an accurate reading. For this reason, a two pulse per revolution fan is recommended.

6.2.2 Power Loss Control
The cBC has full control of the power-up of the SBC, therefore can be used to specify the behavior of the system after an AC power loss condition. Supported modes are “Turn On”, “Remain Off” and “Last State”.
6.2.3 Board Information
The cBC provides a rich data-set of manufacturing and board information such as serial number, EAN number, hardware and firmware revisions, and so on. It also keeps track of dynamically changing data like runtime meter and boot counter.
6.2.4 CPU Fan Connector
The conga-PA3 supports the connection of 12V cooling fans. The signals of the CPU fan are routed to connector X49. The pinout is described below:

6.3 OEM BIOS Customization
The conga-PA3 is equipped with congatec Embedded BIOS, which is based on American Megatrends Inc. Aptio UEFI firmware. The congatec
Embedded BIOS allows system designers to modify the BIOS. For more information about customizing the congatec Embedded BIOS, refer to the congatec System Utility user’s guide, which is called CGUTLm1x.pdf and can be found on the congatec website at www.congatec.com or contact technical support.

The customization features supported are described below:
6.3.1 OEM Default Settings
This feature allows system designers to create and store their own BIOS default configuration. Customized BIOS development by congatec for
OEM default settings is no longer necessary because customers can easily perform this configuration by themselves using the congatec system utility CGUTIL. See congatec application note AN8_Create_OEM_Default_Map.pdf on the congatec website for details on how to add OEM default settings to the congatec Embedded BIOS.
6.3.2 OEM Boot Logo
This feature allows system designers to replace the standard text output displayed during POST with their own BIOS boot logo. Customized
BIOS development by congatec for OEM Boot Logo is no longer necessary because customers can easily perform this configuration by themselves using the congatec system utility CGUTIL. See congatec application note AN8_Create_And_Add_Bootlogo.pdf on the congatec website for details on how to add OEM boot logo to the congatec Embedded BIOS.
6.3.3 OEM POST Logo
This feature allows system designers to replace the congatec POST logo displayed in the upper left corner of the screen during BIOS POST with their own BIOS POST logo. Use the congatec system utility CGUTIL 1.5.4 or later to replace/add the OEM POST logo.
6.3.4 OEM BIOS Code/Data
With the congatec embedded BIOS, it is possible for system designers to add their own code to the BIOS POST process. The congatec
Embedded BIOS first calls the OEM code before handing over control to the OS loader.
Except for custom specific code, this feature can also be used to support Win XP SLP installation, Window 7 SLIC table (OA2.0), Windows 8 OEM activation (OA3.0), verb tables for HDA codecs, PCI/PCIe opROMs, bootloaders, rare graphic modes and Super I/O controller initialization.
Note
The OEM BIOS code of the new UEFI based firmware is only called when the CSM (Compatibility Support Module) is enabled in the BIOS setup menu. Contact congatec technical support for more information on how to add OEM code.
38/44
6.3.5 OEM DXE Driver
This feature allows designers to add their own UEFI DXE driver to the congatec embedded BIOS. Contact congatec technical support for more information on how to add an OEM DXE driver.

6.5 congatec Battery Management Interface
In order to facilitate the development of battery powered mobile systems based on embedded modules, congatec AG has defined an interface for the exchange of data between a CPU module (using an ACPI operating system) and a Smart Battery system. A system developed according to the congatec Battery Management Interface Specification can provide the battery management functions supported by an ACPI capable operating system (e.g. charge state of the battery, information about the battery, alarms/events for certain battery states, ...) without the need for any additional modifications to the system BIOS.
In addtion to the ACPI-Compliant Control Method Battery mentioned above, the latest versions of the conga-PA3 BIOS and board controller firmware also support LTC1760 battery manager from Linear Technology and a battery only solution (no charger). All three battery solutions are supported on the I2C bus and the SMBus. This gives the system designer more flexibility when choosing the appropriate battery sub-system.

API Support (CGOS)
In order to benefit from the above mentioned non-industry standard feature set, congatec provides an API that allows application software developers to easily integrate all these features into their code. The CGOS API (congatec Operating System Application Programming
Interface) is the congatec proprietary API that is available for all commonly used Operating Systems such as Win32, Win64, Win CE, Linux.
The architecture of the CGOS API driver provides the ability to write application software that runs unmodified on all congatec CPU modules.
All the hardware related code is contained within the congatec embedded BIOS on the module. See section 1.1 of the CGOS API software developers guide, which is available on the congatec website .
