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.

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 (0oC to 60oC) . It is not designed to be used within industrial temperature ranges (-40oC to 85oC). When using a heatspreader with conga-PA3 commercial grade variants, the maximum operating temperature refers to any measurable spot on the heatspreader’s surface.

Passive Cooling Solution

Heatspreader

Page 15

congatec AG strongly recommends that you use the appropriate congatec heatspreader on the conga-PA3 and within operating temperatures of 0

C to 60oC. 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.

4.1 CSP Dimension

Note

All measurements are in millimeters. Torque speciﬁcation for the screws is 0.6 Nm. Mechanical system assembly mounting shall follow the valid DIN/IS0 speciﬁcations.

Page 16

4.2 Heatspreader Dimension

Note

All measurements are in millimeters. Torque speciﬁcation for the screws is 0.6 Nm. Mechanical system assembly mounting shall follow the valid DIN/IS0 speciﬁcations.

Caution

When using the heatspreader in a high shock and/or vibration environment, congatec recommends the use of a thread-locking ﬂuid on the cooling solution screws to ensure the above mentioned torque speciﬁcation is maintained.

6.2 congatec Board Controller (cBC)

The conga-PA3 is equipped with a Texas Instruments Tiva™ TM4E1231H6ZRBI microcontroller. This onboard microcontroller plays an important role for most of the congatec BIOS features. 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.

Feature Connector X33

Page 37

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.

6.4 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.

6.5 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 .
