Thermal Considerations
CPU DIE TEMPERATURE
The CPU die temperature is affected by numerous conditions, such as CPU utilization, CPU
speed, ambient air temperature, air flow, thermal effects of adjacent circuit boards, external heat
sources, and many others.
The CPU is protected from over temperature conditions by several mechanisms.
The CPU will automatically slow down by 50% whenever its die temperature exceeds 105° C.
When the temperature falls back below 105° C, the CPU resumes full speed operation.
As a failsafe, if the CPU die temperature climbs above 115° C, the CPU will turn itself off to
prevent damage to the chip.
MODEL DIFFERENCES
VersaLogic offers both standard and extended temperature models of the VL-EPMp-34. The
basic operating temperature specification for both models is shown below.
VL-EPMp-34S: 0° C to +60° C free air, no airflow
VL-EPMp-34E: -40° C to +85° C free air
To reliably function at extreme temperatures the extended temperature model specifications
deviate from the standard model in the following ways:
The DRAM interface is slowed. PC3-6400 memory runs at 600 MHz. PC3-8500
memory runs at 800 MHz.
The DRAM refresh rates are doubled.
The Front Side Bus speed is reduced to 800 MHz.
Maximum processor speed is limited to 1200 MHz.
The graphics core is limited to 400 MHz.
RoHS Compliance
The VL-EPMp-34 is RoHS-compliant.
ABOUT ROHS
In 2003, the European Union issued Directive 2002/95/EC regarding the Restriction of the use of
certain Hazardous Substances (RoHS) in electrical and electronic equipment.
The RoHS directive requires producers of electrical and electronic equipment to reduce to
acceptable levels the presence of six environmentally sensitive substances: lead, mercury,
cadmium, hexavalent chromium, and the presence of polybrominated biphenyls (PBB) and
polybrominated diphenyl ethers (PBDE) flame retardants, in certain electrical and electronic
products sold in the European Union (EU) beginning July 1, 2006.
VersaLogic Corporation is committed to supporting customers with high-quality products and
services meeting the European Union’s RoHS directive.

VL-EPMp-34 Reference Manual 5
Warnings
ELECTROSTATIC DISCHARGE
Warning! Electrostatic discharge (ESD) can damage circuit boards, disk drives and other
components. The circuit board must only be handled at an ESD workstation. If an
approved station is not available, some measure of protection can be provided by
wearing a grounded antistatic wrist strap. Keep all plastic away from the board,
and do not slide the board over any surface.
After removing the board from its protective wrapper, place the board on a
grounded, static-free surface, component side up. Use an antistatic foam pad if
available.
The board should also be protected inside a closed metallic anti-static envelope
during shipment or storage.
Note: The exterior coating on some metallic antistatic bags is sufficiently conductive to
cause excessive battery drain if the bag comes in contact with the battery.
LITHIUM BATTERY
Warning! To prevent shorting, premature failure or damage to the lithium battery, do not
place the board on a conductive surface such as metal, black conductive foam or
the outside surface of a metalized ESD protective pouch. The lithium battery may
explode if mistreated. Do not recharge, disassemble or dispose of in fire. Dispose
of used batteries promptly and in an environmentally suitable manner.
HANDLING CARE
Warning! Care must be taken when handling the board not to touch the exposed circuitry
with your fingers. Though it will not damage the circuitry, it is possible that small
amounts of oil or perspiration on the skin could have enough conductivity to cause
the contents of CMOS RAM to become corrupted through careless handling,
resulting in CMOS resetting to factory defaults.

HARDWARE ASSEMBLY
The VL-EPMp-34 uses a pass-through PCI-104 connector so that expansion modules can be
added to the bottom of the stack. There is no PC/104 (ISA) connector.
The entire assembly can sit on a table top or be secured to a base plate. When bolting the unit
down, make sure to secure all four standoffs to the mounting surface to prevent circuit board
flexing. Standoffs are secured to the top circuit board using four pan head screws. See page 10
for dimensional details. The 5mm x 15.25mm M3 standoffs and screws are available as part
number VL-HDW-105.
An extractor tool is available (part number VL-HDW-201) to separate the PC/104 modules from
the stack. Use caution when using the extractor tool not to damage any board components.

System Features
Power Supply
POWER CONNECTORS
Main power is applied to the VL-EPMp-34 through a 10-pin polarized connector, with mating
connector Berg 69176-010 (Housing) + Berg 47715-000 (Pins). See the table below for
connector pinout and page 13 for location information.
Warning! To prevent severe and possibly irreparable damage to the system, it is critical that
the power connectors are wired correctly. Make sure to use all +5VDC pins and all
ground pins to prevent excess voltage drop. Some manufacturers include a pin-1
indicator on the crimp housing that corresponds to pin-10 of the pinout shown in
Figure 11.

System Features
VL-EPMp-34 Reference Manual 20
Note: The +3.3VDC, +12VDC and -12VDC inputs are required only for expansion
modules that require these voltages.
POWER REQUIREMENTS
The VL-EPMp-34 requires only +5 volts (±5%) for proper operation. The higher voltages
required for the RS-232 ports are generated as needed on-board. Low-voltage supply circuits
provide the many power rails required by the CPU and other on-board devices.
The exact power requirement of the VL-EPMp-34 depends on several factors, including memory
configuration, CPU speed, peripheral connections, type and number of expansion modules and
attached devices. For example, driving long RS-232 lines at high speed can increase power
demand, and USB devices can draw considerable power depending on the device.
The VL-EPMp-34 is equipped with a voltage sensing reset circuit. The system will reset if
voltage drops below 4.63V typically (4.50V min./4.75V max.).
POWER DELIVERY CONSIDERATIONS
The VL-EPMp-34 draws up to 27W (5.4A) as measured on a typical time averaging ammeter.
The board can experience large, short-term current transients during operation, so care must be
taken to provide robust power to the board. A good power delivery method eliminates such
problems as voltage drop and lead inductance. Using the VersaLogic approved power supply and
power cable will ensure high quality power delivery to the board. Customers who design their
own power delivery methods should take into consideration the guidelines below to ensure good
power connections.
Also note that the 5V @ 3.9A (models S, SR) or 2.6A (models E, ER) typical operating current
does not include any off-board power usage that may be fed through the VL-EPMp-34 power
connector. PC/104 boards on the expansion site and USB devices plugged into the board will
source additional 5V power through the VL-EPMp-34 power connector.
Do not use wire smaller than 22 AWG. Use high quality UL 1007 compliant stranded
wire.
The length of the wire should not exceed 12". If a longer wire is used, a larger gauge
wire should also be used.
Avoid using any additional connectors in the power delivery system.
The power and ground leads should be twisted together, or as close together as possible
to reduce lead inductance.
A separate conductor must be used for each of the power pins.
All 5V pins and all ground pins must be independently connected between the power
source and the power connector.
Implement the remote sense feature on your power supply if it has one. Connect the
remote sense lines in tandem with one of the power connector 5V and ground pins. This
is done at the connector to compensate for losses in the power wires.
Use a high quality power supply that can supply a stable voltage while reacting to widely varying
current draws.

System Features
VL-EPMp-34 Reference Manual 21
CPU
The Intel Core 2 Duo processor combines fast performance, using Intel’s 45nm technology, with
advanced power savings features. The SP9300 model used on the VL-EPMp-34 has a maximum
clock rate of 2.26 GHz and a front side bus speed of 1066 MHz, and features 6 MB of L2 cache.
Other features include DDR3 SDRAM support and an integrated display controller. For more
CPU information see the VL-EPMp-34 support page.
System RAM
MEMORY
The VL-EPMp-34 has one DDR3 SO-DIMM socket with the following characteristics:
Storage Capacity Up to 4GB
Voltage 1.5V
Type 800 MHz PC3-6400 or 1067 MHz PC3-8500
CMOS RAM
CLEARING CMOS RAM
You can install a jumper at VN1 pins 5-6 for a minimum of three seconds to erase the contents of
the CMOS RAM and the real-time clock. When clearing CMOS RAM:
1. Power off the VL-EPMp-34.
2. Install a jumper on VN1[5-6] and leave it for three seconds.
3. Remove the jumper.
4. Power on the VL-EPMp-34.
Note: There is no battery on the VL-EPMp-34 mother board, only on the VL-CBR-3406
breakout board. Custom CMOS Setup values and RTC time will not be stored
unless the breakout board with the battery is installed.
CMOS Setup Defaults
The VL-EPMp-34 permits users to modify CMOS Setup defaults. This allows the system to boot
up with user-defined settings from cleared or corrupted CMOS RAM, battery failure or battery-
less operation. All CMOS setup defaults can be changed, except the time and date. CMOS Setup
defaults can be updated with the BIOS Update Utility. See the General BIOS Information page
for details.
EPMQ-34 Sugyon Page VL-
System Features
VL-EPMp-34 Reference Manual 22
Warning! If CMOS Setup default settings make the system unbootable and prevent the user
from entering CMOS Setup, the system can be recovered by switching to the
backup BIOS.
DEFAULT CMOS RAM SETUP VALUES
After CMOS RAM is cleared, the system will load default CMOS RAM parameters the next time
the board is powered on. The default CMOS RAM setup values will be used in order to boot the
system whenever the main CMOS RAM values are blank, or when the system battery is dead or
has been removed from the board.
Primary and Backup BIOS
The Primary system BIOS is field upgradeable using the BIOS upgrade utility (see the VL-
EPMp-34 Support Page for more information). The Backup BIOS is available if the Primary
becomes corrupted. Jumper VN[1-2] controls whether the system uses the Primary or Backup
BIOS. By default the Primary BIOS is selected (jumper removed).
Real Time Clock
The VL-EPMp-34 features a year 2000-compliant, battery-backed 146818-compatible real-time
clock/calendar chip. Under normal battery conditions, the clock maintains accurate timekeeping
functions when the board is powered off.
Note: There is no battery on the VL-EPMp-34 mother board, only on the VL-CBR-3406
breakout board. Custom CMOS Setup values and RTC time will not be stored
unless the breakout board with the battery is installed.
SETTING THE CLOCK
The CMOS Setup utility (accessed by pressing the Delete key during the early boot cycle) can be
used to set the time and date of the real time clock.
Watchdog Timer
A watchdog timer circuit is included on the VL-EPMp-34 board to reset the CPU if proper
software execution fails or a hardware malfunction occurs.
If the watchdog timer is enabled, software must periodically refresh the watchdog timer at a rate
faster than the timer is set to expire (1000 ms minimum). Writing 5Ah to the WDHOLD register
resets the watchdog timeout period. (See "Special Control Register" and "Watchdog Hold
Register.")
System Features
VL-EPMp-34 Reference Manual 23
Fan/Tachometer Monitor
The VL-EPMp-34 includes a fan/tachometer indicator circuit that can generate an interrupt if the
CPU fan speed drops below 1 Hz. Bit D0 of the FANTACH register enables or disables the fan
interrupt. Bit D7 indicates whether the fan is running at or above 1 Hz or below 1Hz. See
"Fan/Tachometer Control Register" for more information.

CONSOLE REDIRECTION
The VL-EPMp-34 can be operated without using the on-board video output by redirecting the
console to the serial communications port. CMOS Setup and some operating systems such as
DOS can use this console for user interaction.
Console redirection settings are configured on the Features tab of CMOS Setup. The default
setting (On Remote User Detect) causes the console not to be redirected to the serial port unless
a signal (a Ctrl-C character) is detected from the terminal. Console redirection can also be set to
Always or Never. Notes on console redirection:
When console redirection is enabled, you can access CMOS Setup by typing Ctrl-C.
The decision to redirect the console is made early in BIOS execution, and cannot be
changed later.
The redirected console uses 115200 baud, 8 data bits, 1 stop bit, no parity, and no flow
control.

SPI is, in its simplest form, a three wire serial bus. One signal is a Clock, driven only by the
permanent Master device on-board. The others are Data In and Data Out with respect to the
Master. The SPX implementation adds additional features, such as chip selects and an interrupt
input to the Master. The Master device initiates all SPI transactions. A slave device responds
when its Chip Select is asserted and it receives Clock pulses from the Master.
The SPI clock rate can be software configured to operate at speeds between 1 MHz and 8 MHz.
Please note that since this clock is divided from a 33 MHz PCI clock, the actual generated
frequencies are not discrete integer MHz frequencies. All four common SPI modes are supported
through the use of clock polarity and clock idle state controls.
VERSALOGIC SPX EXPANSION MODULES
VersaLogic offers a number of SPX modules that provide a variety of standard functions, such as
analog input, digital I/O, CANbus controller, and others. These are small boards (1.2” x 3.775”)
that can mount on the PC/104 stack, using standard PC/104 stand-offs, or up to two feet away
from the base board. For more information, contact VersaLogic at Info@VersaLogic.com.

SPIDATA3 contains the most significant byte (MSB) of the SPI data word. A write to this
register will initiate the SPI clock and, if the MAN_SS bit = 0, will also assert a slave select to
begin an SPI bus transaction. Increasing frame sizes from 8-bit use the lowest address for the
least significant byte of the SPI data word; for example, the LSB of a 24-bit frame would be
SPIDATA1. Data is sent according to the LSBIT_1ST setting. When LSBIT_1ST = 0, the MSbit
of SPIDATA3 is sent first, and received data will be shifted into the LSbit of the selected frame
size set in the SPILEN field. When LSBIT_1ST = 1, the LSbit of the selected frame size is sent
first, and the received data will be shifted into the MSbit of SPIDATA3.
Data returning from the SPI target will normally have its most significant data in the SPIDATA3
register. An exception will occur when LSBIT_1ST = 1 to indicate a right-shift transaction. In
this case the most significant byte of an 8-bit transaction will be located in SPIDATA0, a 16-bit
transaction’s most significant byte will be located in SPIDATA1, and a 24-bit transaction’s most
significant byte will be located in SPIDATA2.
