Processor Information Table 2 Power Consumption Values The tables below provide additional information about the power consumption data for each of the conga-QA3/QA3E variants offered. The values are recorded at various operating mode. Part Memory BIOS Current (Amp.) Size Rev.
Storage: 5% to 95% 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.
® do not use the conga-QA3/QA3E heatspreaders in industrial temperature ranges (-40° to 85°C). Its use is at the risk of the end user. It is the responsibility of the end user to design an optimized thermal solution that meets the needs of their application within the industrial environmental conditions it is required to operate in.
All measurements are in millimeters. Torque specification for heatspreader screws is 0.3 Nm. Mechanical system assembly mounting shall follow the valid DIN/IS0 specifications. The cooling strip found on the conga-QA3/QA3E is connected directly to the ground plane when mounted in the conga-QEVAL evaluation carrier board. For more information about connecting the conga-QA3/QA3E’s PCB cooling plate to the carrier board ground plane, refer to the Qseven Design Guide.
Connector Subsystems The conga-QA3/QA3E is based on the Qseven standard. It therefore has 115 edge fingers on the top and bottom side of the module that ® mate with the 230-pin card-edge MXM connector located on the carrier board. This connector is able to interface the available signals of the conga-QA3/QA3E with the carrier board peripherals.
PCI Express™ The conga-QA3/QA3E offers 3 PCI Express externally on the Edge finger. The lanes are Gen 2 compliant and offer support for full 5 Gb/s bandwidth in each direction per x1 link. Default configuration for the lanes is 3 x1 link. A 1 x2 + 1 x1 link configuration is also possible but requires a special/customized BIOS firmware.
USB 3.0 The conga-QA3/QA3E offers one USB 3.0 interface on the Edge finger. This interface is controlled by an xHCI host controller in the SoC. The host controller allows data transfers of up to 5 Gb/s and supports SuperSpeed, high-speed, full-speed and low-speed USB signalling. The USB SuperSpeed signals should be paired with USB 2.0 port 0 on the carrier board.
The SoC on the conga-QA3/QA3E supports High-bandwidth Digital Content Protection 1.4/2.1 (HDCP) for content protection over wired displays (HDMI, DisplayPort and Embedded DisplayPort). It also supports audio on DP and HDMI. The conga-QA3/QA3E supports up to two independent displays. The display combination must be 1 DDI and 1 LVDS as shown in the table below:...
5.11 The conga-QA3/QA3E offers the LPC (Low Pin Count) bus. The LPC bus corresponds approximately to a serialized ISA bus yet with a significantly reduced number of signals and functionality. Due to the software compatibility to the ISA bus, I/O extensions such as additional serial ports can be easily implemented on an application specific carrier board using this bus.
The conga-QA3/QA3E offers the SPI interface only for booting a BIOS from an SPI Flash device placed on the carrier board. 5.13 I²C Bus The conga-QA3/QA3E supports I2C bus. Thanks to the I2C host controller in the cBC, the I²C bus is multi-master capable and runs at fast mode. 5.14 CAN Bus The conga-QA3/QA3E does not support CAN bus.
Inrush and Maximum Current Peaks on VCC_5V_SB and VCC The inrush current on the conga-QA3/QA3E VCC_5V_SB power rail can go up as high as 6.5A and as high as 12.5A on the conga-QA3/QA3E VCC power rail within a short time (approx 100µs) and with a voltage rise time of 100µs.
The conga-QA3/QA3E is equipped with a Texas Instruments Tiva™ TM4E1231H6ZRBI microcontroller. This onboard microcontroller plays an important role for most of the congatec BIOS features. It fully isolates some of the embedded features such as system monitoring or the I²C bus from the x86 core architecture, which results in higher embedded feature performance and more reliability, even when the x86 processor is in a low power mode.
Fan Control The conga-QA3/QA3E has additional signals and functions to further improve system management. One of these signals is an output signal called FAN_PWMOUT that allows system fan control using a PWM (Pulse Width Modulation) output. Additionally, there is an input signal called FAN_TACHOIN that provides the ability to monitor the system’s fan RPMs (revolutions per minute).
OEM BIOS Code With the congatec embedded BIOS it is even possible for system designers to add their own code to the BIOS POST process. Except for custom specific code, this feature can also be used to support Window 7 SLIC table, verb tables for HDA codecs, rare graphic modes and Super I/O controllers.
EAPI (Embedded Application Programming Interface) is a programming interface defined by the PICMG that addresses this problem. With this unified API it is now possible to run the same application on all vendor’s COMs that offer EAPI driver support. Contact congatec technical support for more information about EAPI.
VT-x) added hardware support in the processor to improve the virtualization performance and robustness. Note congatec does not offer virtual machine monitor (VMM) software. All VMM software support questions and queries should be directed to the VMM software vendor and not congatec technical support.
Native mode. See section 10.4.12 for more information about this. Running in native mode frees up interrupt resources (IRQs 14 and 15) and decreases the chance that there may be a shortage of interrupts when installing devices. Note If your operating system supports native mode then congatec AG recommends you enable it. 7.1.1.4 Thermal Management ACPI is responsible for allowing the operating system to play an important part in the system’s thermal management.
ACPI Specification 2.0 C for more information about passive cooling. ACPI Suspend Modes and Resume Events conga-QA3/QA3E supports S3 (STR= Suspend to RAM). For more information about S3 wake events see section 10.4.6 “ACPI Configuration Submenu”. S4 (Suspend to Disk) is not supported by the BIOS (S4_BIOS) but it is supported by the following operating systems (S4_OS= Hibernate): •...
“#” is not present, the signal is asserted when at a high voltage level. Note Not all the signals described in this section are available on all conga-QA3/QA3E variants.

Specification. To comply with the Qseven Specification, the signals are routed through bidirectional level shifters on the module. The bidirectional level shifters by nature have limited driving strenght. congatec therefore recommends that you route these signals as short as possible.
On Intel Bay Trail SoC, the signal marked with asterisks (**) has a voltage level that is different from the level defined in the Qseven Specification. To comply with the Qseven Specification, the signals are routed through bidirectional level shifters on the module. The bidirectional level shifters by nature have limited driving strenght. congatec therefore recommends that you route these signals as short as possible.

I/O Address Assignment The I/O address assignment of the conga-QA3/QA3E module is functionally identical with a standard PC/AT. The BIOS assigns PCI and PCI Express I/O resources from FFF0h downwards. Non PnP/PCI/PCI Express compliant devices must not consume I/O resources in that area.

Note In ACPI mode, it is not possible for a “Watchdog ACPI Event” handler to directly restart or shutdown the OS. For this reason the congatec BIOS will do one of the following: For Shutdown: An over temperature notification is executed. This causes the OS to shut down in an orderly fashion.
Auto detection is performed by reading an EDID data set via the video I²C bus. WVGA 800x480 1x24 (01Bh) The number in brackets specifies the congatec internal number of the respective panel data set. SVGA 800x600 1x18 (01Ah) Note: Customized EDID™ utilizes an OEM defined EDID™ data set stored in the BIOS flash device.

Note 1. The term ‘AC power loss’ stands for the state when the module looses the standby voltage on the 5V_SB pins. On congatec modules, the standby voltage is continuously monitored after the system is turned off. If within 30 seconds the standby voltage is no longer detected, then this is considered an AC power loss condition.
Additional BIOS Features The conga-QA30 uses a congatec/AMI AptioEFI that is stored in an onboard Flash Rom chip and can be updated using the congatec System Utility (version 1.5.0 and later), which is available in a DOS based command line, Win32 command line, Win32 GUI, and Linux version.
