2 Introduction

2.1 ETX®-DC

The ETX®-DC module brings latest 45 nm technology to the well-established ETX® 3.0 form factor. The Intel® Atom™ N270 processor is well-balanced in terms of power consumption, performance and pricing. Especially, long-term availability turns ETX®-DC to become a perfect successor for your existing ETX® designs.

With the ETX®-DC, your investments in ETX® designs can be sustained for years. Due to latest technology, your products become more valuable.

With full support for 18 bit and 24 bit LVDS panels, the ETX®-DC is a full successor for ETX®-PM or ETX®-PM3

ETX® modules are like components, plugged into an application-specific carrier board. They have highly standardized interfaces and ease scalability and interchangeability. Rapid development and short time-to-market are your benefits.

2.2 ETX® Documentation

This product manual serves as one of three principal references for an ETX® design. It documents the specifications and features of ETX®-DC. The other two references, which are available from the Kontron Embedded Modules GmbH Web site, include:

» The ETX® Component SBC™ Specification defines the ETX® module form factor, pinout, and signals. You

should read this first.

» The ETX® Component SBC™ Design Guide serves as a general guide for baseboard design, with a focus on

maximum flexibility to accommodate a range of ETX® modules.

Note: Some of the information contained within this product manual applies only to certain product revisions

(Prev: xxx). If certain information applies to specific product revisions (Prev: xxx) it will be stated. Please check the product revision of your module to see if this information is applicable.

ETX-DC®/ Introduction

2.3 ETX® Benefits

Embedded technology extended (ETX®) modules are very compact (~100mm square, 12mm thick), highly integrated computers. All ETX® modules feature a standardized form factor and a standardized connector layout that carry a specified set of signals. This standardization allows designers to create a single-system baseboard that can accept present and future ETX® modules.

ETX® modules include common personal computer (PC) peripheral functions such as:

» Graphics » Parallel, Serial, and USB ports » Keyboard/mouse » Ethernet » Sound » IDE

The baseboard designer can optimize exactly how each of these functions implements physically. Designers can place connectors precisely where needed for the application on a baseboard designed to optimally fit a system’s packaging.

Peripheral PCI or ISA buses can be implemented directly on the baseboard rather than on mechanically unwieldy expansion cards. The ability to build a system on a single baseboard using the computer as one plug-in component simplifies packaging, eliminates cabling, and significantly reduces system-level cost.

A single baseboard design can use a range of ETX® modules. This flexibility can differentiate products at various price/performance points, or to design future proof systems that have a built-in upgrade path. The modularity of an ETX® solution also ensures against obsolescence as computer technology evolves. A properly designed ETX® baseboard can work with several successive generations of ETX® modules.

An ETX® baseboard design has many advantages of a custom, computer-board design but delivers better obsolescence protection, greatly reduced engineering effort, and faster time to market.

3.8 MTBF

The following MTBF (Mean Time Between Failure) values were calculated using a combination of manufacturer’s test data, if the data was available, and a Bellcore calculation for the remaining parts.

The Bellcore calculation used is “Method 1 Case 1”. In that particular method the components are assumed to be

operating at a 50 % stress level in a 40° C ambient environment and the system is assumed to have not been burned

in. Manufacturer’s data has been used wherever possible. The manufacturer’s data, when used, is specified at 50° C,

so in that sense the following results are slightly conservative. The MTBF values shown below are for a 40° C in an office or telecommunications environment. Higher temperatures and other environmental stresses (extreme altitude, vibration, salt water exposure, etc.) lower MTBF values.

System MTBF (hours): 176102 @ 40°C

Notes: Fans usually shipped with Kontron Embedded Modules GmbH products have 50,000-hour typical operating

life. The above estimates assume no fan, but a passive heat sinking arrangement Estimated RTC battery life (as opposed to battery failures) is not accounted for in the above figures and need to be considered for separately. Battery life depends on both temperature and operating conditions. When the Kontron unit has external power; the only battery drain is from leakage paths.

4.3.2 Connector X1 Signal Description

PCI Bus

The implementation of this subsystem complies with the ETX® Specification. Implementation information is provided in the ETX® Design Guide. Refer to the documentation for additional information. The PCI bus with its signals: AD[31:0], C/BE[3:0]#, DEVSEL#, FRAME#, IRDY#, PAR, GPERR#, REQ[3:0]#, SERR#, STOP#, TRDY#, INT[D:A]# is 5V tolerant.

USB

Three USB host controllers (two 1.1 UHCI and one EHCI high-speed 2.0 controller) are on the Intel® 82801GB south bridge device. The USB controllers comply with both versions 1.1 and 2.0 of the USB standard and are backward compatible. The three controllers implement a root hub, which have two USB ports each.

Configuration

The USB controllers are PCI bus devices. The BIOS allocates required system resources during configuration of the PCI bus.

Audio

The ETX®-DC PCI audio controller is integrated in the Intel® 82801GB southbridge. The audio codec is compatible with AC97.

Configuration

The audio controller is a PCI bus device. The BIOS allocates required system resources during configuration of the PCI device.

Serial IRQ

The serial IRQ pin offers a standardized interface to link interrupt request lines to a single wire.

Configuration

The serial IRQ machine is in “Continuous Mode” per default and can be changed in the BIOS setup, the frame size is 21

frames and the start frame pulse width is 4 clocks.

3.3V Power Supply for External Components

The ETX®-DC offers the ability to connect external 3.3V devices to the onboard-generated supply voltage. Pin 12 and Pin 16 of Connector X1 are used to connect to the +3.3V ±5% power supply. The maximum external load is 500mA. Contact Kontron Embedded Systems Technical Support for help with this feature.

Warning: Do not connect 3.3 V pins to external 3.3 V supply.

For additional information, refer to the ETX® Design Guide, I2C application notes, and JIDA specifications, all of which are available on the Kontron Embedded Systems Web site.

4.4 Connector X2 (ISA Bus)

Notes: *To protect external power lines of peripheral devices, make sure that:

- The wires have the right diameter to withstand the maximum available current.

- The enclosure of the peripheral device fulfils the fire-protection requirements of IEC/EN60950

** IRQ9 is used for SCI in ACPI mode. Do not use for legacy ISA devices.

Parallel Port / Floppy Interfaces

You can configure ETX®-DC’s parallel port interfaces as conventional PC parallel ports or as an interface for a floppydisk drive. You can select the operating mode in the BIOS settings and by a hardware mode-select pin.

If Pin X3-51 (LPT/FLPY#) is grounded at boot time, the floppy support mode is selected. If the pin is left floating or is held high, parallel-port mode is selected. The mode selection is determined at boot time. It cannot be changed until the next boot cycle.

Notes: *To protect external power lines of peripheral devices, make sure that:

- the wires have the right diameter to withstand the maximum available current

- the enclosure of the peripheral device fulfils the fire-protection requirements of IEC/EN60950

4.7.3 Connector X4 Signal Description

IDE Ports

The IDE host adapter is capable of DMA-100 operation and supports only one single IDE channel which is connected to the primary channel of the ETX® connector X4. Per default it is set to DMA-33, to achieve the best compatibility to most baseboard implementations. Implementation information is provided in the ETX® Design Guide. Refer to those documents for additional information.

Configuration:

The IDE host adapter is a PCI bus device. It is configured by the BIOS during PCI device configuration. You can disable it in setup. Resources used by the primary IDE host adapter are compatible with the PC/AT.

Ethernet

The Ethernet interface is based on the Intel® 82562 Fast Ethernet PCI controller. This 32-bit PCI controller is a fully integrated 10/100BASE-TX LAN solution.

The Ethernet interface requires an external transformer. See the ETX® Design Guide for suggestions on transformer selection.

Configuration:

The Ethernet interface is a PCI device. The BIOS setup automatically configures it during configuration of the PCI device.

Note: Implementation and limitation information is provided in the ETX® Design Guide from document revision

2.1. Refer to the documentation for additional information.

Power Control

Power Good / Reset Input:

The ETX®-DC provides an external input for a power-good signal or a manual- reset pushbutton. The implementation of this subsystem complies with the ETX® Specification. Implementation information is provided in the ETX® Design Guide. Refer to the documentation for additional information.

ETX-DC®/ Special Features

5 Special Features

5.1 Watchdog Timer

The watchdog timer is implemented within the Winbond W83627HG. The WDT can also be controlled by the JIDA BIOS support. The application software should strobe the WDT to prevent its timeout. Upon timeout, the WDT resets and restarts the system. This provides a way to recover from program crashes or lockups.

Configuration

You can program the timeout period for the watchdog timer in two ranges:

» 1-second increments from 1 to 255 seconds » 1-minute increments from 1 to 255 minutes

The watchdog can release a NMI or a reset.

Contact Kontron Embedded Modules technical support for information on programming and operating the WDT.

5.2 SATA Support

The ETX®-DC supports two SATA ports compliant to the ETX® 3.0 specification

5.3 Restrictions

The ETX-DC® has following restrictions compared to some other ETX® products:

5.3.1 ISA Bus

The ETX-DC® is usually equipped with a PCI2ISA bridge which does not support DMA transfers; therefore e.g. the floppy interface of an external SuperI/O controller is not supported.

Optionally a LPC2ISA bridge can be equipped as a customized version of the product, but then there is only very limited memory access on ISA bus possible.

5.3.2 ISA VGA

There is no support for ISA graphic cards on ETCX-DC®.

5.3.3 LVDS

The ETX-DC® supports only 18bit LVDS panels, because only 3 LVDS data pairs are supported by the chipset.

ETX-DC®/ Design Considerations

35

6 Design Considerations

6.1 Thermal Management

A heat-spreader plate assembly is available from Kontron Embedded Modules GmbH for the ETX®-DC. The heatspreader plate on top of this assembly is NOT a heat sink. It works as an ETX®-standard thermal interface to use with a heat sink or other cooling device.

External cooling must be provided to maintain the heat-spreader plate at proper operating temperatures. Under worst-case conditions, the cooling mechanism must maintain an ambient air and heat-spreader plate temperature of 60° C or less.

The aluminum slugs and thermal pads on the underside of the heat-spreader assembly implement thermal interfaces between the heat spreader plate and the major heat-generating components on the ETX®-DC. About 80 percent of the power dissipated within the module is conducted to the heatspreader plate and can be removed by the cooling solution.

The heat dissipated into the plate ranges from 12 watts. Design a cooling solution to dissipate the heat load on a heat-spreader plate at a minimum of 25 watts to accommodate all ETX® modules.

You can use many thermal-management solutions with the heat-spreader plates, including active and passive approaches. The optimum cooling solution varies, depending on the ETX® application and environmental conditions. Please see the ETX® Design Guide for further information on thermal management.

ETX-DC®/ Design Considerations

36

6.2 Heat spreader

Documentation of ETX-DC® Heatspreader and Cooling Solutions are provided at the customer section of the Kontron Website.

6.3 ETX-DC® onboard fan connector

This section describes how to connect a fan to the connector located directly on the ETX®-DC. With certain BIOSsettings it is possible to control the fan depending on the Active Trip Point temperature. The fan switches on/off depending on the adjusted Active Trip Point temperature. In order for this feature to function properly an ACPI compliant OS is necessary.

Note: The ETX®-DC BIOS supports only turning the onboard FAN ON/OFF. For additional support 3rd party software

is necessary.

7 Important Technology Information

The following technological information is designed to give the reader a better understanding of some of features of the ETX®-DC. This information can be referenced when reading the System Resources and BIOS Operation sections that follow. There are also references to additional documentation that will help to develop a better understanding of the technical information described herein.

7.1 I/O APIC vs 8259 PIC Interrupt mode

The I/O APIC (Advanced Programmable Interrupt Controller) handles interrupts differently then the 8259 PIC. The following information explains these differences.

7.1.1 Method of interrupts transmission

The I/O APIC transmits interrupts through the system bus and interrupts are handled without the needs for the processor to run an interrupt acknowledge cycle.

7.1.2 Interrupt priority

The priority of interrupts in the I/O APIC is independent of the interrupt number.

7.1.3 More interrupts

The I/O APIC in the chipset of the ETX®-DC supports a total of 24 interrupts. The APIC is not supported by all operating systems. The APIC mode must be enabled in the BIOS setup before the OS installation. APIC only works in ACPI mode.

Note: Enable the APIC mode if your OS supports it.

7.2 Thermal Monitor and Catastrophic Thermal Protection

The Thermal Monitor within the Intel® processor helps to control the processor temperature.

7.3 ACPI Suspend Modes and Resume Events

The ETX®-DC, supports the S1 (POS=Power On Suspend) state and S3 state (=Save to Ram). S4 (=Save to Disk) is not supported by the BIOS (S4_BIOS) but it is supported by the following operating systems:

» WinME » Win2k » WinXP » Vista

ETX-DC®/ Important Technology Information

39

The following events resume the system from S1:

» Power Button » USB Wake Events » PCI Bus signal PME# » LAN WOL

The following event resumes the system from S3:

» Power Button » PCI Bus signal PME# » LAN WOL

The following event resumes the system from S5:

» Power Button » WOL

Note: LAN WOL must be enabled in the driver.
