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.

Flat-Panel Interfaces
ETX®-DC modules can implement an LVDS flat-panel interface called JUMPtec Intelligent LVDS Interface (JILI). These modules do not implement a parallel digital flat-panel interface called JUMPtec Intelligent Digital Interface (JIDI).
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.
**This signal is not supported on the ETX®-DC.
