2 Introduction

2.1 The microETXexpress®-PV COM

The Kontron microETXexpress®-PV Computer-on-Module (COM) extends the COM

Express® specification to include a small module form factor (95 x 95 mm)

with the commonly used COM Express® Type 2 connector for use on ultra-low

power embedded devices. The microETXexpress®-PV COM design enables the

development of energy-saving devices based on the second generation 1.66 GHz

Intel® Atom™ processor D510, D410, and N450 technology and the Intel® I/O

Controller Hub 82801HBM (ICH8M) with the secure development path of an

established, future-proof industry standard, the COM Express® Type 2 form

factor.

The Kontron microETXexpress®-PV module processor has an integrated memory

controller for up to 2 GB DDR2 RAM (2x 1GB configuration). The graphics core

has a maximum resolution of 1400x1050 VGA and 18-bit single channel LVDS for

WXGA (1366x768). With five PCI Express lanes for flexible configurations as

well as PCI, I

multi-interface, ultra-low power carrier board designs. These special

features make this 95 x 95 mm Computer-on-Module a key solution for

applications like infotainment, digital signage, POS/POI, medical technology,

2

C, SPI, and LPC bus, the microETXexpress®-PV COM is ideal for

and automation that require both mobile and compact stationary low power

devices.

All modules in the Kontron microETXexpress® family are compatible with the

COM Express® standard (Pin-out Type 2) and thus ensure easy

interchangeability as well as design scalability and future migration paths.

The microETXexpress®-PV COM is a complete PC with standard interfaces such as

USB, Gigabit Ethernet, SATA II, and PATA as well as additional options like

high-definition audio (HDA) and an LVDS flat panel interface.

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 such as IDE or parallel ATA (PATA) to Low Voltage

Differential Signaling (LVDS) interfaces including the PCI bus, PCI Express*,

and Serial ATA (SATA).

Kontron microETXexpress-PV User’s Guide

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

factor (125mm x 95mm)

» microETXexpress® modules are Kontron COM Express® modules in the 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(55mm x 84mm)

NOTE: The Kontron microETXexpress®-PV module takes advantage of new

features introduced in the PICMG COM COM.0R2.0 COM Express® Specification.

2.3 Understanding the COM Functionality

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

microETXexpress®-PV COM. The other two references, which are available from

your Kontron support representative or from PICMG, include:

» The COM Express® Specification, R2.0, 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 .

» 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

Compact form factor (95 x 95 mm) Computer-on-Module Express (COM Express) modules are very compact, highly integrated computers that use the Type 2 COM Express® connector pin-out. All microETXexpress® modules feature a standardized form factor and a standardized connector layout for a specified set of signals, as defined in the PICMG COM Express® specification. This standardization lets designers create a single-system baseboard that can accept present and future microETXexpress® modules.

Kontron microETXexpress® 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

Kontron microETXexpress-PV User’s Guide

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 Low Pin Count (LPC) interface signals are connected to the Intel® ICH8M. The LPC low-speed interface can be used for peripheral circuits. For example,

40

Kontron microETXexpress-PV User’s Guide

it can be used as an external super I/O controller to combine legacy-device support into a single IC. The implementation of this subsystem complies with the COM Express® specification. For additional implementation information, refer to the PICMG COM Express® Design Guide on the PICMG website.

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: Connecting more than one device to the LPC bus requires using a

clock buffer. 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.

Figure 6: Standard Clock Buffer

NOTE: When using a standard clock buffer on the baseboard, be aware that the

generated delay must be considered for the length matching of the layout.

4.1.16 Power Control Interface

Power Good (PWR_OK)

The microETXexpress®-PV 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 must be high-level (> 1.7V) to power on the module in normal ATX mode.

Power Button (PWRBTN#)

43

Kontron microETXexpress-PV User’s Guide

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.

To force a power-off the module, press and hold the power button for at least four seconds. Depending on the OS in use, only one press of the Power button initiate the clean power down of the module.

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.

WARNING: Please note that in order to fulfill the COM Express requirements, pressing the reset button will cause a complete power cycle.

Power Supply

The microETXexpress®-PV COM has a wide range of power input, from 4.75V to 18V DC. The supply voltage is applied through 24 pins (VCC) on the module connectors. In ATX mode with 5V standby voltage, the VCC input must be higher than the standby voltage.

In general, single supply mode means that the module is able to function with a single supply (no standby voltage is necessary). All other functions attributed to the ATX mode remain functional.

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 (Battery) Mode:

To enable the single supply mode the BIOS setup must be changed. The “Battery Mode” must be enabled from the Boot menu. Setting “Power Scheme” option to “Battery Mode” in the BIOS will enable the following features:

» The PWR_OK# state is ignored and the input voltage monitoring will be

enabled

An internal voltage monitor will let the board start (after a power button event or self-power up) when the input voltage is above 4.75V. The voltage monitor accomplishes this by controlling, via the CPLD, the BATLOW# signal of the ICH8M. When BATLOW# is asserted the ICH8M will defer the platform to leave the power states S3 – Suspend to RAM, S4 – Suspend to disk or S5 – Soft off. Once BATLOW# goes inactive the ICH8M will let the platform transition to S0.

» Onboard debug LED will be disabled

The onboard debug LED will be turned off to reduce the power consumption, especially when not in S0.

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® N450 Atom processor supports 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. Modules with either the D510 or D410 CPU do not support Enhanced Intel SpeedStep Technology. 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 Onboard Hardware Monitor

The microETXexpress®-PV COM has an onboard hardware monitor. The following

-

A voltage divider is present on this pin in order to be able to read the full range of input voltage. The reading must be multiplied by 2 to have the real value when using third party software.

-

To read this sensor properly when using third party software, the HWM GPIO 1 must be enabled. This feature prevents unnecessary drainage of the RTC battery.

5.4 Watchdog

This feature is implemented through the LPC on the CPLD and offers a dual-

stage watchdog. It first generates an NMI and, after 1mS, a reset is

generated. The application software should strobe the WDTimer 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 triggered through

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

For information about programming this feature, see the JIDA32/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.

5.5 JIDA Non-Volatile and CMOS Settings

The microETXexpress® -PV module allows saving the CMOS settings externally. If the RTC battery fails to keep CMOS voltage at a certain level, the external EEPROM restores the previous settings. If the CMOS is lost, all previous settings are restored and an error message is displayed on the POST screen: “CMOS Date/Time Not Set”.

From there, users have two choices: “Press F1 to Run SETUP” or “Press F2 to load default values and continue”. If the choice is to keep all previous settings, then Press “F1” and enter the new date and new hour. Press F10 to save and exit. Your previous settings are set correctly and the time and

49

date are set accordingly. Pressing F2 sets the date to the BIOS build date and the hour is set to 00:00:00. The default values are reloaded and the system will boot on the default bootable device.

5.6 General Purpose Input and Output (GPIO)

The microETXexpress®-PV COM provides eight GPIOs (always enabled)that can be accessed through the module connector described in the pin-out lists, in Section 4.1. The GPIO viewer can be enabled in the BIOS setup.

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

6 Design Considerations

6.1 Thermal Management

A heat spreader plate assembly is available from Kontron Embedded Modules for the microETXexpress®-PV COM. The heat spreader plate on top of this assembly is NOT a heat sink. It works as a COM Express®-standard thermal interface to be used 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 microETXexpress®-PV. About 80 percent of the power dissipated within the module is conducted to the heat spreader plate and can be removed by the cooling solution.

Kontron also has defined a passive heat sink that can be used in place of the heat spreader plate to provide additional cooling. You can use many thermalmanagement solutions with the heat spreader plates, including active and passive approaches. The optimum cooling solution varies, depending on the COM Express® application and environmental conditions. Drawings for both the heat spreader plate and the passive heat sink are available on request. Also, see the PICMG COM Express® Design Guide on the PICMG website for further information about thermal management.

6.2 Heat Spreader Dimensions

Documentation for the microETXexpress®-PV COM heat spreader and cooling solutions is provided at http://emdcustomersection.kontron.com.

6.3 Onboard Fan Connector

This section describes how to connect an optional fan to the connector located directly on the microETXexpress®-PV COM. With certain BIOS-settings 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. This feature requires an ACPI-compliant OS to function properly. The fan PWM control is done on the GND pin rather than the positive side. Please do not use pin 3 as a ground connection. See schematic below for more details.

6.3.1 Fan Connector Electrical Characteristics

The fan connector has two supply pins. One of the supply pins outputs a regulated +5V with a maximum current of 350mA. The second supply pin is connected directly from the VCC_12V supply from the COM Express connector .The maximum current supported on that output is 125mA @ 60°C ambient because it is current limited by a resettable fuse. The voltage is not limited to +12V on this pin.

WARNING: Be aware of the wide range input voltage and acceptable fan voltage

when connecting a fan to ht VCC_12V (Pin 2) output.

7.2 Memory Area

The first 640 KBytes of DRAM are used as main memory. With DOS, you can address 1 MByte of memory directly. Memory area above 1 MByte (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. See 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.
