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
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*

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).

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.

All dimensions are shown in millimeters. The COM Express™ specification says
that these holes should be ± 0.25mm [±0.010"], unless otherwise noted. The
tolerances for placement of the COM Express connector with respect to the peg
holes (dimensions [16.50, 6.00]) should be ± 0.10mm [±0.004. The pads are
tied to the PCB ground plane.

3.4.2 Supply Current (Windows XP SP3)
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.
