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.

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.

5.1 Primary Connector Rows A and B

The following subsystems can be found on the primary connector rows A and B.

5.1.1 Serial ATA™ (SATA)

Two Serial ATA connections are provided via the Intel® CG82NM10 (NM10) PCH. These SATA ports are capable of up to 3.0 Gb/s transfer rate. The conga-TCA provides 2 SATA ports externally.

5.1.2 USB 2.0

The conga-TCA offers one EHCI USB host controller that supports USB high speed signalling and four UHCI host controllers that supports both low and full speed signalling through Intel® CG82NM10 (NM10) PCH. These controllers comply with USB standard 1.1 and 2.0 and offer a total of 8 USB ports via connector rows A and B. Each port is capable of supporting USB 1.1 and 2.0 compliant devices. For more information about how the USB host controllers are routed, see section 7.5.

5.1.3 High Deﬁnition Audio (HDA) Interface

The conga-TCA provides an interface that supports the connection of HDA audio codecs.

5.1.4 Gigabit Ethernet

The conga-TCA offers Gigabit Ethernet with the integration of Realtek RTL8111E Gigabit Ethernet Controller. This controller is implemented through the use of one PCI Express lane, and runs at a 1.25GHz signalling rate with x1 link width. The Ethernet interface consists of 4 pairs of low voltage differential pair signals designated from MDI0± to MDI3± plus three LED signals for link activity indicators. These signals can be used to connect to a 10/100/1000 BaseT RJ45 connector with integrated or external isolation magnetics on the carrier board.

Note

The GBE0_LINK# output is only active during a 100Mbit or 1Gbit connection, it is not active during a 10Mbit connection. This is a limitation of Ethernet controller since it only has 3 LED outputs, ACT#, LINK100# and LINK1000#. The GBE0_LINK# signal is a logic AND of the GBE0_LINK100# and GBE0_LINK1000# signals on the conga-TCA module.

Page 24

5.1.5 LPC Bus

conga-TCA offers the LPC (Low Pin Count) bus through the use of the Intel® CG82NM10 (NM10) PCH. There are many devices available for this Intel® deﬁned bus. The LPC bus corresponds approximately to a serialized ISA bus yet with a signiﬁcantly reduced number of signals. 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 baseboard using this bus. See section 9.2.1 for more information about the LPC Bus.

5.1.6 I²C Bus Fast mode

The I²C bus is implemented through the congatec board controller (STMicroelectronics STM32). It provides a Fast Mode multi-master I²C Bus that has maximum I²C bandwidth.

5.1.7 PCI Express™

The Intel® CG82NM10 (NM10) PCH chipset featured on the conga-TCA offers four PCI Express™ lanes. Through the use of a PCIe switch, the conga-TCA provides up to ﬁve external PCI Express™ lanes if the optional USB 3.0 is not implemented. The Gen1 PCI Express™ interface offers support for full 2.5 Gb/s bandwidth in each direction per x1 link. The conga-TCA also has a sixth PCI Express™ lane that is utilized by the onboard Gigabit Ethernet interface and therefore not available externally.

The ﬁve external PCI Express™ lanes are available on the A,B connector row. The PCI Express interface is based on the PCI Express Speciﬁcation

1.0a (Gen 1 supporting up to 2.5 Gb/s transfer rate).

5.1.8 ExpressCard™

The conga-TCA supports the implementation of ExpressCards, which requires the dedication of one USB port and a x1 PCI Express link for each ExpressCard used.

5.1.9 Graphics Output (VGA/CRT)

The conga-TCA offers a VGA interface on the A-B connector. The interface supports up to 1920x1200 resolution at 60 Hz.

Page 25

5.1.10 LCD

The conga-TCA offers an LVDS interface on the AB connector. The interface supports:

• single channel LVDS with color depths of 18 bpp (D2000/N2000 series) or 24 bpp (D2000 series only)

• integrated ﬂat panel interface with clock frequency up to 112 MHz

• VESA and OpenLDI LVDS color mappings

• automatic panel detection via Embedded Panel Interface based on VESA EDIDTM 1.3

• resolution up to 1366x768 for 18 bpp and up to 1440x900 for 24 bpp

5.1.11 SPI

A SPI interface that supports booting from an external SPI ﬂash is available on the conga-TCA via the Intel® CG82NM10 (NM10) PCH . The Intel® CG82NM10 (NM10) PCH implements a SPI interface as an alternative interface for the BIOS ﬂash device. A SPI ﬂash device can be used as a replacement for the Firmware Hub

5.1.12 General Purpose Serial Interface

Two TTL compatible two wire ports are available on Type 6 COM Express modules. These pins are designated SER0_TX, SER0_RX, SER1_TX and SER1_RX. Data out of the module is on the _TX pins. Hardware handshaking and hardware ﬂow control are not supported. The module asynchronous serial ports are intended for general purpose use and for use with debugging software that make use of the “console redirect” features available in many operating systems.

Note

The General Purpose Serial Interface is not supported on the conga-TCA module.

5.1.13 General Purpose Input/Output

The conga-TCA provides various general purpose inputs and outputs for custom system design. These GPIOs are provided via Intel® CG82NM10 (NM10) and routed to the A,B connector through the congatec Board Controller (STM32F100R8).

Page 26

5.1.14 Power Control

PWR_OK

Power OK from main power supply or carrier board voltage regulator circuitry. A high value indicates that the power is good and the module can start its onboard power sequencing. Carrier board hardware must drive this signal low until all power rails and clocks are stable. Releasing PWR_OK too early or not driving it low at all can cause numerous boot up problems. It is a good design practice to delay the PWR_OK signal a little (typically 100ms) after all carrier board power rails are up, to ensure a stable system. See screenshot below.

Note

The module is kept in reset as long as the PWR_OK is driven by carrier board hardware.

Page 27

The conga-TCA PWR_OK input circuitry is implemented as shown below:

The voltage divider ensures that the input complies with 3.3V CMOS characteristic and also allows for carrier board designs that are not driving PWR_OK. Although the PWR_OK input is not mandatory for the onboard power-up sequencing, it is strongly recommended that the carrier board hardware drives the signal low until it is safe to let the module boot-up.

When considering the above shown voltage divider circuitry and the transistor stage, the voltage measured at the PWR_OK input pin may be only around 0.8V when the 12V is applied to the module. Actively driving PWR_OK high is compliant to the COM Express speciﬁcation but this can cause back driving. Therefore, congatec recommends driving the PWR_OK low to keep the module in reset and tri-state PWR_OK when the carrier board hardware is ready to boot.

The three typical usage scenarios for a carrier board design are:

• Connect PWR_OK to the “power good” signal of an ATX type power supply.

• Connect PWR_OK to the last voltage regulator in the chain on the carrier board.

• Simply pull PWR_OK with a 1k resistor to the carrier board 3.3V power rail.

With this solution, it must be ensured that by the time the 3.3V is up, all carrier board hardware is fully powered and all clocks are stable.

The conga-TCA provides support for controlling ATX-style power supplies. When not using an ATX power supply then the conga-TCA’s pins SUS_S3/PS_ON, 5V_SB, and PWRBTN# should be left unconnected.

SUS_S3#/PS_ON#

The SUS_S3#/PS_ON# (pin A15 on the A-B connector) signal is an active-low output that can be used to turn on the main outputs of an ATXstyle power supply. In order to accomplish this the signal must be inverted with an inverter/transistor that is supplied by standby voltage and is located on the carrier board.

PWRBTN#

When using ATX-style power supplies PWRBTN# (pin B12 on the A-B connector) is used to connect to a momentary-contact, active-low debounced push-button input while the other terminal on the push-button must be connected to ground. This signal is internally pulled up to 3V_SB using a 10k resistor. When PWRBTN# is asserted it indicates that an operator wants to turn the power on or off. The response to this signal from the system may vary as a result of modiﬁcations made in BIOS settings or by system software.

Power Supply Implementation Guidelines

12 volt input power is the sole operational power source for the conga-TCA. The remaining necessary voltages are internally generated on the module using onboard voltage regulators. A carrier board designer should be aware of the following important information when designing a power supply for a conga-TCA application:

• It has also been noticed that on some occasions, problems occur when using a 12V power supply that produces non monotonic voltage when powered up. The problem is that some internal circuits on the module (e.g. clock-generator chips) will generate their own reset signals when the supply voltage exceeds a certain voltage threshold. A voltage dip after passing this threshold may lead to these circuits becoming confused resulting in a malfunction. It must be mentioned that this problem is quite rare but has been observed in some mobile power supply applications. The best way to ensure that this problem is not encountered is to observe the power supply rise waveform through the use of an oscilloscope to determine if the rise is indeed monotonic and does not have any dips. This should be done during the power supply qualiﬁcation phase therefore ensuring that the above mentioned problem doesn’t arise in the application. For more information about this issue visit www.formfactors.org and view page 25 ﬁgure 7 of the document “ATX12V Power Supply Design Guide V2.2”.

5.1.15 Power Management

ACPI 3.0 compliant with battery support. Also supports Suspend to RAM (S3).

Page 29

5.2 Secondary Connector Rows C and D

The following subsystems can be found on the secondary connector rows C and D.

5.2.1 USB 3.0

The conga-TCA offers two USB 3.0 ports with the integration of a USB 3.0 xHCI compliant host controller (Texas Instrument TUSB7320). This controller is implemented through the use of one PCI Express™ lane and provides SuperSpeed, high-speed, full-speed and low-speed trafﬁc on the bus.

Note

The USB 3.0 is an optional feature.

5.2.2 HDMI

The Intel® Atom™ D2000/N2000 series processors on the conga-TCA supports integrated HDMI, which is multiplexed onto the Digital Display Interface (DDI) of the COM Express connector. The processor provides two ports capable of supporting HDMI. See section 8.5 of this document for more information about enabling HDMI peripherals.

5.2.3 DisplayPort (DP)

The conga-TCA offers two DP ports, each capable of supporting link-speeds of 1.62 Gbps and 2.7 Gbps on 1, 2 or 4 data lanes. The DP is multiplexed onto the Digital Display Interface (DDI) of the COM Express connector. The DisplayPort speciﬁcation is a VESA standard aimed at consolidating internal and external connection methods to reduce device complexity, supporting key cross industry applications, and providing performance scalability to enable the next generation of displays. The Intel® Atom™ D2000/N2000 series processors can support a maximum of 2 DP ports simultaneously. See section 8.5 of this document for more information about enabling DisplayPort peripherals.

6 Additional Features

6.1 congatec Board Controller (cBC)

The conga-TCA is equipped with a STMicroelectronics STM32 microcontroller. This onboard microcontroller plays an important role for most of the congatec embedded/industrial PC 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. It also ensures that the congatec embedded feature set is fully compatible amongst all congatec modules.

6.2 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.

6.3 Watchdog

The conga-TCA is equipped with a multi stage watchdog solution that is triggered by software. The COM Express™ Speciﬁcation does not provide support for external hardware triggering of the Watchdog, which means the conga-TCA does not support external hardware triggering. For more information about the Watchdog feature see the BIOS setup description section 10.4.2 of this document and application note AN3_Watchdog.pdf on the congatec AG website at www.congatec.com.

Note

The conga-TCA module does not support the watchdog NMI mode. COM Express type 6 modules do not support the PCI bus and therefore the PCI_SERR# signal is not available. There is no way to drive a NMI to the processor without the presence of the PCI_SERR# PCI bus signal.

6.4 I2C Bus

The conga-TCA offers support for the frequently used I2C bus. Thanks to the I2C host controller in the cBC the I2C bus is multimaster capable and runs at fast mode.

Page 31

6.5 Power Loss Control

The cBC has full control of the power-up of the module and therefore can be used to specify the behaviour of the system after a AC power loss condition. Supported modes are “Always On”, “Remain Off” and “Last State”.

6.6 Embedded BIOS

The conga-TCA is equipped with congatec Embedded BIOS, which is based on American Megatrends Inc. Aptio UEFI ﬁrmware. These are the most important embedded PC features:

6.6.1 CMOS Backup in Non Volatile Memory

A copy of the CMOS memory (SRAM) is stored in the BIOS ﬂash device. This prevents the system from not booting up with the correct system conﬁguration if the backup battery (RTC battery) has failed. Additionally, it provides the ability to create systems that do not require a CMOS backup battery.

6.6.2 OEM CMOS Default Settings and OEM BIOS Logo

This feature allows system designers to create and store their own CMOS default conﬁguration and BIOS logo (splash screen) within the BIOS ﬂash device. Customized BIOS development by congatec for these changes is no longer necessary because customers can easily do these changes by themselves using the congatec system utility CGUITL.

6.6.3 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 Win XP SLP installation, Window 7 SLIC table, verb tables for HDA codecs, rare graphic modes and Super I/O controllers.

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 AG website at www.congatec.com or contact congatec technical support.

Page 32

6.6.4 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.

The conga-TCA BIOS fully supports this interface. For more information about this subject visit the congatec website and view the following documents:

• congatec Battery Management Interface Speciﬁcation

• Battery System Design Guide

• conga-SBM3 User’s Guide

6.6.5 API Support (CGOS/EAPI)

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 .

Other COM (Computer on Modules) vendors offer similar driver solutions for these kind of embedded PC features, which are by nature proprietary. All the API solutions that can be found on the market are not compatible to each other. As a result, writing application software that can run on more than one vendor’s COM is not so easy. Customers have to change their application software when switching to another COM vendor. 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.

Page 33

6.7 Security Features

The conga-TCA can be equipped optionally with a “Trusted Platform Module“ (TPM 1.2). This TPM 1.2 includes coprocessors to calculate efﬁcient hash and RSA algorithms with key lengths up to 2,048 bits as well as a real random number generator. Security sensitive applications like gaming and e-commerce will beneﬁt also with improved authentication, integrity and conﬁdence levels.

6.8 Suspend to Ram

The Suspend to RAM feature is available on the conga-TCA.

7 conga Tech Notes

The conga-TCA has some technological features that require additional explanation. The following section will give the reader a better understanding of some of these features. This information will also help to gain a better understanding of the information found in the System Resources section of this user’s guide as well as some of the setup nodes found in the BIOS Setup Program description section.

7.1 Intel® Matrix Storage Technology

The Intel

CG82NM10 (NM10) PCH provides support for Intel® Matrix Storage Technology, allowing AHCI functionality.

7.1.1 AHCI

The Intel

CG82NM10 (NM10) PCH provides hardware support for Advanced Host Controller Interface (AHCI), a new programming interface for SATA host controllers. Platforms supporting AHCI may take advantage of performance features such as no master/slave designation for SATA devices (each device is treated as a master) and hardware-assisted native command queuing. AHCI also provides usability enhancements such as Hot-Plug.

7.2 Intel® Processor Features

7.2.1 Thermal Monitor and Catastrophic Thermal Protection

Intel® Atom™ D2000/N2000 series processors have a thermal monitor feature that helps to control the processor temperature. The integrated TCC (Thermal Control Circuit) activates if the processor silicon reaches its maximum operating temperature. The activation temperature, that the Intel® Thermal Monitor uses to activate the TCC, cannot be conﬁgured by the user nor is it software visible.

The Thermal Monitor can control the processor temperature through the use of two different methods deﬁned as TM1 and TM2. TM1 method consists of the modulation (starting and stopping) of the processor clocks at a 50% duty cycle. The TM2 method initiates an Enhanced Intel Speedstep transition to the lowest performance state once the processor silicon reaches the maximum operating temperature.

Note

The maximum operating temperature for Intel® Atom™ D2000/N2000 series processors is 100°C.

Two modes are supported by the Thermal Monitor to activate the TCC. They are called Automatic and On-Demand. No additional hardware, software, or handling routines are necessary when using Automatic Mode.

Page 35

Note

To ensure that the TCC is active for only short periods of time, thus reducing the impact on processor performance to a minimum, it is necessary to have a properly designed thermal solution. The Intel® Atom™ D2000/N2000 series processor’s respective datasheet can provide you with more information about this subject.

THERMTRIP# signal is used by Intel

’s Atom™ D2000/N2000 series processors for catastrophic thermal protection. If the processor’s silicon reaches a temperature of approximately 125°C then the processor signal THERMTRIP# will go active and the system will automatically shut down to prevent any damage to the processor as a result of overheating. The THERMTRIP# signal activation is completely independent from processor activity and therefore does not produce any bus cycles.

Note

In order for THERMTRIP# to be able to automatically switch off the system, it is necessary to use an ATX style power supply.

7.2.2 Processor Performance Control

Intel® Atom™ D2000/N2000 series processors found on the conga-TCA run at different voltage/frequency states (performance states), which is referred to as Enhanced Intel® SpeedStep® technology (EIST). Operating systems that support performance control take advantage of microprocessors that use several different performance states in order to efﬁciently operate the processor when it’s not being fully utilized. The operating system will determine the necessary performance state that the processor should run at so that the optimal balance between performance and power consumption can be achieved during runtime.

The Windows family of operating systems links its processor performance control policy to the power scheme setting. You must ensure that your power scheme setting you choose has the ability to support Enhanced Intel

SpeedStep® technology.

7.3 Thermal Management

ACPI is responsible for allowing the operating system to play an important part in the system’s thermal management. This results in the operating system having the ability to take control of the operating environment by implementing cooling decisions according to the demands put on the CPU by the application.

The conga-TCA ACPI thermal solution offers three different cooling policies.

• Passive Cooling

When the temperature in the thermal zone must be reduced, the operating system can decrease the power consumption of the processor by throttling the processor clock. One of the advantages of this cooling policy is that passive cooling devices (in this case the processor) do not

Page 36

produce any noise. Use the “passive cooling trip point” setup node in the BIOS setup program to determine the temperature threshold that the operating system will use to start or stop the passive cooling procedure.

• Active Cooling

During this cooling policy the operating system is turning the fan on/off. Although active cooling devices consume power and produce noise, they also have the ability to cool the thermal zone without having to reduce the overall system performance. Use the “active cooling trip point” setup node in the BIOS setup program to determine the temperature threshold that the operating system will use to start the active cooling device. It is stopped again when the temperature goes below the threshold (4°C hysteresis).

• Critical Trip Point

If the temperature in the thermal zone reaches a critical point then the operating system will perform a system shut down in an orderly fashion in order to ensure that there is no damage done to the system as result of high temperatures. Use the “critical trip point” setup node in the BIOS setup program to determine the temperature threshold that the operating system will use to shut down the system.

Note

The end user must determine the cooling preferences for the system by using the setup nodes in the BIOS setup program to establish the appropriate trip points.

If passive cooling is activated and the processor temperature is above the trip point the processor clock is throttled according to the formula below.

∆P[%] = TC1(T

n-Tn-1

) + TC2(Tn-Tt)

• ∆P is the performance delta

• Tt is the target temperature = critical trip point

• The two coefﬁcients TC1 and TC2 and the sampling period TSP are hardware dependent constants. These constants are set to ﬁxed values for the conga-TCA:

• TC1= 1

• TC2= 5

• TSP= 5 seconds

See section 12 of the ACPI Speciﬁcation 2.0 C for more information about passive cooling.

7.4 ACPI Suspend Modes and Resume Events

conga-TCA supports S3 (STR= Suspend to RAM). For more information about S3 wake events see section 10.4.5 “ACPI 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):

• Windows 7, Windows Vista, Linux

This table lists the “Wake Events” that resume the system from S3 unless otherwise stated in the “Conditions/Remarks” column:

Wake Event Conditions/Remarks

Power Button Wakes unconditionally from S3-S5. Onboard LAN Event Device driver must be conﬁgured for Wake On LAN support. SMBALERT# Wakes unconditionally from S3-S5. PCI Express WAKE# Wakes unconditionally from S3-S5. WAKE# Wakes uncondionally from S3. PME# Activate the wake up capabilities of a PCI device using Windows Device Manager conﬁguration options for this device OR set Resume On

PME# to Enabled in the Power setup menu.

USB Mouse/Keyboard Event When Standby mode is set to S3, USB hardware must be powered by standby power source.

Set USB Device Wakeup from S3/S4 to ENABLED in the ACPI setup menu (if setup node is available in BIOS setup program). In Device Manager look for the keyboard/mouse devices. Go to the Power Management tab and check ‘Allow this device to bring the

computer out of standby’. RTC Alarm Activate and conﬁgure Resume On RTC Alarm in the Power setup menu. Only available in S5. Watchdog Power Button Event Wakes unconditionally from S3-S5.

7.5 USB 2.0 EHCI Host Controller Support

The Intel® CG82NM10 (NM10) PCH supports up to eight USB ports. The 8 available USB ports are shared between 1 EHCI host controller and the 4 UHCI host controllers.

The muxing between the UHCI and EHCI host controllers is performed by the port-routing logic integrated into the EHC functionality. If a device not capable of USB 2.0 high-speed signalling is connected or if the EHCI software drivers are not present,then the UHCI controller owns the port. Owning the port means that the differential output is driven by the owner and the input stream is only visible to the owner. The host controller that is not the owner of the port internally sees a disconnected port.

The Intel

CG82NM10 (NM10) PCH allows the USB Debug Port trafﬁc to be routed in and out of Port 0. When in this mode, the Enhanced Host

controller is the owner of Port 0.

8 Signal Descriptions and Pinout Tables

The following section describes the signals found on COM Express™ Type VI connectors used for congatec AG modules. The pinout of the modules complies with COM Express Type 6.0 Rev. 2.1.

Table 2 describes the terminology used in this section for the Signal Description tables. The PU/PD column indicates if a COM Express™ module pull-up or pull-down resistor has been used, if the ﬁeld entry area in this column for the signal is empty, then no pull-up or pull-down resistor has been implemented by congatec.

The “#” symbol at the end of the signal name indicates that the active or asserted state occurs when the signal is at a low voltage level. When “#” is not present, the signal is asserted when at a high voltage level.

Note

The Signal Description tables do not list internal pull-ups or pull-downs implemented by the chip vendors, only pull-ups or pull-downs implemented by congatec are listed. For information about the internal pull-ups or pull-downs implemented by the chip vendors, refer to the respective chip’s datasheet.

The TYPE pins indicate to the Carrier Board the Pin-out Type that is implemented on the module. The pins are tied on the module to either ground (GND) or are no-connects (NC). For Pinout Type 1, these pins are don’t care (X).

PDS TYPE[0:2]# signals are

available on all modules following the Type 2-6 Pinout standard. The conga-TCA is based on the COM Express Type 6 pinout therefore the pins 0 and 1 are not connected and pin 2 is connected to GND.

Caution

The signals listed in the table above are used as chipset conﬁguration straps during system reset. In this condition (during reset), they are inputs that are pulled to the correct state by either COM Express™ internally implemented resistors or chipset internally implemented resistors that are located on the module. No external DC loads or external pull-up or pull-down resistors should change the conﬁguration of the signals listed in the above table. External resistors may override the internal strap states and cause the COM Express™ module to malfunction and/ or cause irreparable damage to the module.

Note

T.O.M. = Top of memory = max. DRAM installed

9.2 I/O Address Assignment

The I/O address assignment of the conga-TCA 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.

Page 66

9.2.1 LPC Bus

On the conga-TCA, the internal PCI Bus acts as the subtractive decoding agent. All I/O cycles that are not positively decoded are forwarded to the internal PCI Bus. Only speciﬁed I/O ranges are forwarded to the LPC Bus by default.

In the congatec Embedded BIOS, the following I/O address ranges are sent to the LPC Bus:

2Eh – 2Fh 4Eh – 4Fh

60h 62h 64h 66h

200h – 20Fh

3F0h - 3F5h

3F7h

2F8h – 2FFh

378h – 37Fh

778h – 77Fh

F8h – 3FFh3

Parts of these ranges are not available if a Super I/O is used on the carrier board. If a Super I/O is not implemented on the carrier board, then these ranges are available for customer use. If you require additional LPC Bus resources other than those mentioned above, or more information about this subject, contact congatec technical support for assistance.

Watchdog ACPI Event

Shutdown

Restart

Select the operating system event that is initiated by the watchdog ACPI event. These options perform a critical but orderly operating system shutdown or restart.

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.

For Restart: An ACPI fatal error is reported to the OS.

Additionally, the conga-TCA module does not support the watchdog NMI mode. COM Express type 6 modules do not support the PCI bus and therefore the PCI_SERR# signal is not available. There is no way to drive a NMI to the processor without the presence of the PCI_SERR# PCI bus signal.

►CSM & Option ROM Parameters

submenu

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. If the standby voltage remains stable for 30 seconds, then it is assumed that the system was switched off properly.

2. Inexpensive ATX power supplies often have problems with short AC power sags. When using these ATX power supplies it is possible that the system turns off but does not switch back on, even when the PS_ON# signal is asserted correctly by the module. In this case, the internal circuitry of the ATX power supply has become confused. Usually another AC power off/on cycle is necessary to recover from this situation

11 Additional BIOS Features

The conga-TCA uses a congatec/AMI AptioEFI that is stored in an onboard Flash Rom chip and can be updated using the congatec System Utility, which is available in a DOS based command line, Win32 command line, Win32 GUI, and Linux version.

The BIOS displays a message during POST and on the main setup screen identifying the BIOS project name and a revision code. The initial production BIOS is identiﬁed as TCEDR1xx where TCED is the congatec internal project name, R is the identiﬁer for a BIOS ROM ﬁle, 1 is the so called feature number and xx is the major and minor revision number.

The size of the conga-TCA BIOS binary is approximately 4MB.

11.1 Supported Flash Devices

The conga-TCA supports the following ﬂash devices:

• Atmel AT25DF321-SU

• Greenliant Systems SST25VF032B-66-4I-S2AF

• Macronix MX25L3206EM2I-12G

The ﬂash devices listed above can be used on the carrier board for external BIOS support. For more information about external BIOS support, refer to the Application Note AN7_External_BIOS_Update.pdf on the congatec website at http://www.congatec.com.

11.2 Updating the BIOS

BIOS updates are often used by OEMs to correct platform issues discovered after the board has been shipped or when new features are added to the BIOS.

For more information about “Updating the BIOS” refer to the user’s guide for the congatec System Utility, which is called CGUTLm1x.pdf and can be found on the congatec AG website at www.congatec.com.

11.3 BIOS Security Features

The BIOS provides a setup administrator password that limits access to the BIOS setup menu.

11.4 Hard Disk Security Features

Hard Disk Security uses the Security Mode feature commands deﬁned in the ATA speciﬁcation. This functionality allows users to protect data using drive-level passwords. The passwords are kept within the drive, so data is protected even if the drive is moved to another computer system.

The BIOS provides the ability to ‘lock’ and ‘unlock’ drives using the security password. A ‘locked’ drive will be detected by the system, but no data can be accessed. Accessing data on a ‘locked’ drive requires the proper password to ‘unlock’ the disk.

The BIOS enables users to enable/disable hard disk security for each hard drive in setup. A master password is available if the user can not remember the user password. Both passwords can be set independently however the drive will only lock if a user password is installed. The max length of the passwords is 32 bytes.

During POST each hard drive is checked for security mode feature support. In case the drive supports the feature and it is locked, the BIOS prompts the user for the user password. If the user does not enter the correct user password within four attempts, the user is notiﬁed that the drive is locked and POST continues as normal. If the user enters the correct password, the drive is unlocked until the next reboot.

In order to ensure that the ATA security features are not compromised by viruses or malicious programs when the drive is typically unlocked, the BIOS disables the ATA security features at the end of POST to prevent their misuse. Without this protection it would be possible for viruses or malicious programs to set a password on a drive thereby blocking the user from accessing the data.
