2 Introduction

2.1 The ETXexpress®-AI COM

The Kontron ETXexpress®-AI Computer-on-Module (COM) extends the COM Express™

specification to include a basic form factor (125mmx95mm) module with the

commonly used COM Express™ Type 2 connector or new Type 6 connector for use

in graphics-intensive applications for the high-end performance sector. The

ETXexpress®-AI COM design enables the development of high-performance,

customized, energy efficient applications based on the 32-nm Intel® Core

i7/CoreTM i5 processor technology and the Mobile Intel® QM57 Platform

Controller Hub. This module also provides the secure development path of an

established, future-proof PICMG COM Express

The Kontron ETXexpress®-AI module processor technology supports an integrated

memory controller for up to 8 GBytes of dual-channel DDR3 SODIMM RAM with ECC

TM

industry standard.

TM

support (2x 204-pin SODIMM sockets) and integrated 45nm HD graphics with

DisplayPort (DP) support. With a comprehensive set of interfaces on the COM

Express Type 2 or Type 6 connector, including 1xPCI Express*Gen 2 graphics

(PEG), 6xPCI Express x1,4xSATA, 1xPATA (Type 2 only), SDVO/DP/DVI/HDMI (Type

6 only), 8xUSB 2.0, Gigabit Ethernet, dual-channel LVDS, VGA, and Intel® High

Definition Audio, this module offers improved computing and graphics

performance. These special features make this 125mmx95mm Computer-on-Module a

key solution for applications like gaming, digital signage,

network/telecommunications, medical technology, automation, and MAG

(military, aerospace, government) that require application-specific

customization for rapid time-to-market.

All modules in the Kontron ETXexpress® family are compatible with the COM

Express™ standard (connector pin-out Type 2 and now the new Type 6) and thus

ensure easy interchangeability as well as design scalability and future

migration paths.

2.2 Naming Clarifications

The COM Express™ standard defines a Computer-On-Module, or COM, with all the

components necessary for a bootable host computer, packaged as a super-

component. The interfaces provide a smooth transition path from legacy

parallel interfaces to Low Voltage Differential Signaling (LVDS) interfaces

Kontron ETXexpress-AI User’s Guide

including the PCI bus, PCI Express*, Serial ATA (SATA), and parallel ATA

(PATA).

» ETXexpress® modules are Kontron COM Express™ modules in the basic form

factor (125mm x 95mm)

» microETXexpress® modules are Kontron COM Express™ modules in a compact form

factor (95mm x 95mm)

» nanoETXexpress® modules are Kontron COM Express™ compatible modules in an

ultra-small form factor that follow pin-out type 1 or type 10 (55mm x 84mm)

2.3 Understanding the COM Functionality

All Kontron microETXexpress® and ETXexpress® modules contain two connectors (X1A and X1B), each with two rows. The primary connector rows are Row A and Row B (connector X1A). The secondary connector rows are Row C and Row D (connector X1B). There are a few different orderable SKUs for the EXTexpressAI module; one for a module that uses COM Express connector Type 2 and another SKU for a version using the new pin-out Type 6 connector. Additional SKUs for ETXexpress-AI modules that support non-ECC memory are also available. Type 6 is a new addition to the PICMG COM Express standard and it is documented in Revision 2.0 of the PICMG specification. The Type 6 pin-out is based on Type 2 and also supports new features on the secondary connector (rows C and D). The key changes are:

» The PCI interface is no longer supported and the pins are used instead for

digital display interfaces (DDI) and two additional PCI Express lanes

» The IDE (PATA) parallel interface is no longer supported and the pins are

used instead for additional transmit and receive pairs for four USB 3.0 ports. (USB 3.0 is not supported on the ETXexpress-AI module.)

» Three dedicated DDI ports have been added. Ports 1, 2, and 3 can be

configured individually for Display Port (DP), HDMI, or DVI and port 1 can also be used for SDV0.

» SDVO is no longer supported on the PEG port. Instead SDVO is multiplexed on

DDI port 1.

» Two optional two-wire RS232 serial ports have been added using pins

formerly assigned to 12V signals.

The primary connector (Row A and Row B) on the ETXexpress®-AI COM features the following functionality:

» Analog VGA graphics » LVDS 24-bit dual channel » Gigabit Ethernet LAN » Serial ATA (SATA) » PCI Express*

» Intel® High Definition Audio (HDA)

The secondary connector (Row C and Row D) supports the following buses and I/O:

» SDVO/DP/DVI/HDMI (Type 6 only) » DP/DVI/HDMI (Type 6 only) » PCI Express (Type 6 only) » PCI 32/33 (Type 2 only) » Parallel ATA (PATA) via SATA-to-PATA bridge (Type 2 only build option)

NOTE: For full descriptions of the COM Express Type 2 and Type 6 pin-outs,

refer to the PICMG documentation that can be obtained from the the PICMG website.

2.4 COM Express™ Documentation

This product manual serves as one of three principal references for this COM

Express™ module design. It documents the specifications and features of the

ETXexpress®-AI COM. The other two references, which are available from your

Kontron support representative or from PICMG, include:

» The PICMG COM Express™ Specification, which defines the COM Express™ module

form factor, pin-out, and signals. This document can be obtained by filling out the order form on the PIGMG website at http://www.picmg.com . NOTE: The version that documents the Type 6 connector is Revision 2.0

» The PICMG COM Express™ Design Guide, which serves as a general guide for

baseboard design, with a focus on maximum flexibility to accommodate a wide range of COM Express™ modules. This guide is on the PICMG website at

http://www.picmg.com .

2.5 COM Express™ COM Benefits

Basic form factor (125mm x 95 mm) Computer-on-Module Express (COM Express) modules are highly integrated computers. All ETXexpress® modules feature a standardized form factor and a standardized connector layout for a specified set of signals. Each ETXexpress® module is based on the Connector Type 2 pinout or new Type 6 pin-out of the COM Express™ specification (PICMG COM.0 R2).

5

Kontron ETXexpress-AI User’s Guide

This standardization lets designers create a single-system baseboard that can accept present and future COM Express modules.

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

» Graphics » USB ports » Ethernet » Audio » IDE/PATA and SATA hard disk drive formats

Baseboard designers can optimize exactly how each of these functions is implemented physically for the intended application by placing connectors precisely where they are needed on a baseboard that is designed for an optimal fit in the system packaging.

A peripheral PCI bus 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 super-component simplifies packaging, eliminates cabling, and significantly reduces system-level total cost of ownership.

A single baseboard design can use a range of COM Express modules. This flexibility enables product differentiation at various price/performance points, and the design of future-proof systems with a built-in upgrade path. The modularity of a COM Express solution also ensures against obsolescence as computer technology evolves. A properly designed COM Express baseboard can work with several successive generations of COM Express modules.

A COM Express baseboard design has many of the advantages of a custom, computer-board design, but delivers better obsolescence protection, greatly reduced engineering effort, and faster time to market.

The testing performed to capture the supply current data used tested modules mounted on a Kontron evaluation board with a mouse and keyboard connected. The power consumption tests were executed in Windows XP (with SP3) using a tool to stress the CPU at 100% load. The power measurement values were captured after 15 minutes of full load or a stable CPU core temperature of 90°C. To ensure a stable die temperature, a corresponding heatsink was used to hold the temperature under the critical trip point. All boards were equipped with a 2x1024-MB DDR3 SDRAM with ECC. The modules were tested using the maximum CPU frequency. For more detailed information, refer to the “Power Consumption” diagrams on the EMD Customer section of the Kontron website.

TM

The LPC bus does not support DMA (Direct Memory Access) and therefore imposes limitations for ISA bus and standard I/Os (SIOs) like floppy or LPT interface implementations.

WARNING: When more than one device is connected to the LPC bus, a clock

buffer is required. Because of the power management of the LPC bus, you must use great care with clock buffers that require synchronization as they could prevent the board from booting up.

4.4.10 Power Control Interface

Power Good (PWR_OK)

The ETXexpress®-AI COM provides an external input for a power-good signal (pin B24). The implementation of this subsystem complies with the COM Express™ Specification. PWR_OK is internally pulled up to 3.3V and must be high-level to power on the module.

Power Button (PWRBTN#)

The power button (pin B12) is available through the module connector as defined in the pin-out list. To start the module using the power button, the PWRBTN# signal must be at least 50ms (50ms ≤ t < 4sec) at low-level power.

You can put the module into power-off mode by pressing the power button for at least four seconds.

Reset Button (SYS_RESET#)

The reset button (pin B49) is available through the module connector as defined in the pin-out list. The module stays in reset as long as SYS_RESET# is grounded.

Power Supply

The ETXexpress®-AI COM has a wide range of power inputs, from 8V to 18V DC. The supply voltage is applied through 42 pins (VCC) on the module connector. In ATX mode with 5V standby voltage, the VCC input must be higher than the standby voltage.

In general, single supply mode means the module starts as soon as power is applied to the module and ATX mode is for power button-controlled operation.

ATX Mode / Single Supply Mode

ATX Mode:

When an ATX power supply is connected, PWR_OK is set to low-level and VCC is off. Pressing the power button enables the ATX PSU setting PWR_OK to highlevel and powers on VCC. The ATX PSU is controlled by the PS_ON# signal, which is generated by SUS_S3# via inversion.

Single Supply Mode:

In single supply mode the module starts automatically when VCC power is connected and Power Good input is open or at high-level (internal PU to

3.3V). PS_ON# is not used in single supply mode.

To power on the module from the S5 state, press the power button or reconnect VCC.

2

C application notes and JIDA specifications, which are available on the Kontron website at

http://emdcustomersection.kontron.com/.

See the Chapter 8, “BIOS Operation” for supported I

2

C features.

SMBus

System Management Bus (SMBbus) signals are connected to the SMBus controller, which is located on the QM57 platform controller hub. The SMBus is a two-wire bi-directional bus (clock and serial data) used for system management tasks such as reading parameters from a memory card or reading temperatures and voltages of system components.

The SMBus uses the same signaling scheme as the I

2

C bus.

PCI Bus

The Intel® QM57 PCH provides a standard PCI 2.3 32-bit/33 MHz interface on the COM Express™ connector Type 2 implementation. The COM Express Type 6 connector does not support a PCI interface.

Kontron ETXexpress-AI User’s Guide

5 Special Features

5.1 Hyper-Threading

Hyper-Threading (officially termed Hyper-Threading Technology or HTT) is an Intel-proprietary technology used to improve parallelization of computations performed on PCs. Hyper-threading works by duplicating certain sections of the processor—those that store the architectural state -- but not duplicating the main execution resources. A hyper-threading equipped processor can appear to be two "logical" processors to the host operating system, thus allowing the operating system to schedule two threads or processes simultaneously. Hyper Threading Technology support always depends on the operating system.

5.2 Enhanced Speedstep Technology

The Intel® Core™ i7 and Core™ i5 processors support the Intel® Enhanced SpeedStep™ technology, which automatically switches the processor between maximum performance mode and battery-optimized mode, depending on the needs of the application being run. Speedstep technology lets you optimize the system performance to match application requirements. When powered by a battery or running in idle mode, the processor drops to lower frequencies (by changing the CPU ratios) and voltage to conserving battery life while maintaining a high level of performance. The frequency is set back to high automatically, allowing you to customize performance.

NOTE: To use Enhanced SpeedStep™ technology, you need an operating system

that supports it.

Disabling Speedstep in the BIOS enables manual control of CPU performance. You can set the CPU performance state in the BIOS setup or use third-party software to control CPU performance states.

5.3 Watchdog

This feature is implemented within an I2C Watchdog and offers a single-stage watchdog. You can configure the Watchdog Timer (WDTimer) using the Kontron EAPI, or through the BIOS setup, or directly through register settings. The application software should strobe the WDTrigger to prevent a timeout. The WDTrigger resets and restarts the system after a timeout to provide a way to recover from program crashes or lockups.

The Watchdog can be enabled through:

» BIOS Setup » K-Station

64

Kontron ETXexpress-AI User’s Guide

» Direct programming over register settings

The Watchdog can be triggered through

» K-Station » Direct programming (i.e., writing data into one register of the CPLD)

For information about programming this feature, see the K-Station driver packet in the Kontron Customer section or contact your local sales support representative to get an application note about low level programming.

5.4 General Purpose Input and Output (GPIO)

The ETXexpress®-AI COM provides eight GPIOs that can be accessed through the module COM Express™ connector described in the pin-out lists, in Chapter 4, “COM Connectors”.

NOTE: GPIO cannot drive applications faster than 2 msec. Data transfer

rates up to 1 kHz maximum are recommended.

5.5 Fast I2C

The ETXexpress®-AI COM integrates two configurable I2C buses. The external I2C clock and data signals are provided via the CPLD on COM Express™ connector pins B33/B34 and the (LVDS) I PCH are assigned to COM Express™ connector pins A83/A84. The I offers full multimaster and clock stretching support.

7.2 Memory Area

The first 640 KBytes of DRAM are used as main memory. With DOS, you can address 1 MB of memory directly. Memory area above 1 MB (high memory, extended memory) is accessed under DOS via special drivers such as HIMEM.SYS and EMM386.EXE, which are part of the operating system. Please refer to the operating system documentation or special textbooks for information about HIMEM.SYS and EMM386.EXE.

Other operating systems (Linux or Windows versions) allow you to address the full memory area directly.
