Introduction

Cautions
Electrostatic Discharge
CAUTION:
Electrostatic discharge (ESD) can damage circuit boards, disk drives, and other
components. Handle circuit board at an ESD workstation. If an approved station is not
available, wearing a grounded antistatic wrist strap provides some measure of
protection. 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.
Ship and store the board inside a closed metallic antistatic envelope for protection.
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 bottom side of the Lion.
Handling Care
CAUTION:
Avoid touching the exposed circuitry with your fingers when handling the board. 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.
Earth Ground Requirement
CAUTION:
All mounting standoffs (four on PC/104 boards, eight on EBX and EPIC boards) should
be connected to earth ground (chassis ground). This provides proper grounding for EMI
purposes.

Jumper block V1 is located on the bottom side of the board. The board ships with two jumpers
installed, but only one side of each jumper is placed on a pin of the V1 jumper block. In this
configuration, the jumpers do not connect any signals. They are placed this way in case you need
to configure the COM ports for RS-485 termination.

Power Supply
Power Connectors
Main power is applied to the Lion through a 12-pin polarized connector (J19), with mating
connector Molex 55959-1230 (housing) + Molex 51353-1200 (pins). See Table 7 for connector
pinout.
CAUTION:
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 +5 VDC pins and all ground
pins to prevent excess voltage drop. The power connector is not fuse or diode
protected. Proper polarity must be followed otherwise damage will occur.

Power Requirements
The Lion requires +5.15 VDC 2 %) for proper operation. Variable low-voltage supply circuits
provide power to the CPU and other on-board devices. +/- 12V and 3.3V power can also be
provided if a PCIe/104 Express expansion card requires these power rails but these are not
required for the EPMe-42.
The exact power requirement of the VL-EPMe-42 depends on several factors, including memory
configuration, CPU clock rate, peripheral connections, and the type and number of expansion
modules and attached devices.
Power Delivery Considerations
Using the VersaLogic approved power supply (VL-PS- ATX12- 300A) and power cable (VL-CBR-
1205) ensures 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.
In addition, the specifications for typical operating current do not include any off-board power
usage that may be fed through the Lion power connector. Expansion boards and USB devices
plugged into the board will source additional power through the Lion 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 18 inches.
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 power input pins and all ground pins must be independently connected between the
power source and the power connector.
Use a high quality power supply that can supply a stable voltage while reacting to widely
varying current draws.

powered. The battery connection can be made to either (but not both) of the following:
J12 external battery connector
J13 user I/O connector
Integrator’s Note:
There is no on-board battery. The Lion board will operate without a battery, but to save the date
and time, use a VL-CBR-4005 paddleboard (which includes a battery) or connect an external
battery to connector J12.

Serial Ports
The Lion features four on-board 16550-based serial communications channels Two are standard
PC I/O address (COM1,COM2) and two are via HSUARTs in the Kaby Lake processor (COM3,
COM4). COM1, COM2 are multiprotocol RS-232/422/485 ports. COM3, COM4 are RS-232.
COM Port Configuration (COM1, COM2)
Use the BIOS Setup utility to select between RS-232 and RS-422/485 operating modes.
Jumper block V1 configures the serial ports for RS-422/485 operation. See Jumper Summary for
details. The 120 termination resistor should be enabled RS-485 endpoint stations; termination is
optional for RS-422. It should be disabled for all RS-232 modes and RS-485 intermediate stations.
If RS-485 mode is used, the differential twisted pair (TxD+/RxD+ and TxD-/RxD-) is formed by
connecting plus-to-plus and minus-to-minus.
RS-485 Mode Line Driver Control
The transmit line driver can be automatically turned on and off based on data availability in the
UART output FIFO. This mode can be enabled in the BIOS Setup utility. The transmit line driver

Lion (VL-EPMe-42) Reference Manual 28
The VersaLogic VL-CBR-2402 cable is a USB 3.0 Type-C to Type-A socket adapter. The VL-
CBR-2402 cable can be used to connect the Lion to any certified USB 3.0 hubs.
LEDs
FPGA Controlled LEDs
The FPGA controls three LEDs (the Blue is an individual LED and the Green/Yellow is a dual-
package):
Blue used for SATA (and mSATA) activity indication.
Green used for Power-Good indication when in S0 (and will do a very low duty cycle
pulse when in sleep modes as an indication that the board is still powered).
Yellow used for errors or debug (software enables this).
The Yellow LED can be also used for debug purposes.
Power LEDs
The power LED on the VL-CBR-4005 indicates that the paddleboard is being powered by the 3.3
V supply (though it does not indicate that all S0 power supplies are within specified limits). The
LED is lit only when the board is in the S0 power state. If the board enters a Sleep or Hibernate
mode, the LED will not be lit.
Power Button
Connector J13 includes an input for a power button. Shorting J13 (pin 17) to ground causes the
board to enter an S5 power state (similar to the Windows Shutdown state). Shorting it again
returns the board to the S0 power state and reboots the board. The button can be configured in
Windows to enter an S3 power state (Sleep, Standby, or Suspend-to-RAM), an S4 power state
(Hibernate or Suspend-to-Disk), or an S5 power state (Shutdown or Soft-Off).
The input can be connected to ground using the normally open contacts of a pushbutton switch or
a relay, or with a switching transistor (open-collector or open-drain) capable of sinking 1 mA. The
input must be driven to a voltage between 0 V and 500 mV to be recognized by the Lion. Do not
add an external pull-up resistor to this signal.
This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
In configurations where a power button is not connected to the board, if the system is put into an
S5 state, power can be restored by turning off the power supply and turning it back on. This
behavior is set by default in the BIOS.

Supported Power States
The table below lists the supported power states.
Table 15. Supported Power States
Power state Description
S0 (G0) Working
S1 (G1-S1)
All processor caches are flushed, and the CPUs stop executing instructions. Power to
the CPUs and RAM is maintained.
Devices that do not indicate they must remain on may
be powered down.
S3 (G1-S3) Commonly referred to as Standby, Sleep, or Suspend-to-RAM. RAM remains powered.
S4 (G1-S4)
Hibernation or Suspend-to-Disk. All content of main memory is saved to non-volatile
memory, such as a hard drive, and is powered down.
S5 (G2)
Soft Off. Almost the same as G3 Mechanical Off, except that the power supply still
provides power, at a minimum, to the power button to allow return to S0. A full reboot is
required. No previous content is retained. Other components may remain powered so
the computer can "wake" on input from the keyboard, clock, modem, LAN, or USB
device.
G3 Mechanical off (ATX supply switch turned off).
Pushbutton Reset
Connector J13 includes an input for a pushbutton reset switch. Shorting J13 (pin 18) to ground
causes the Lion to reboot.
The input can be connected to ground using the normally open contacts of a pushbutton switch or
a relay, or with a switching transistor (open-collector or open-drain) capable of sinking 1 mA. The
input must be driven to a voltage between 0 V and 500 mV to be recognized by the Lion. Do not
add an external pull-up resistor to this signal.
This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
Speaker
Connector J13 includes a speaker output signal at pin 15. The VL-CBR-4005 paddleboard
provides a Piezo-electric speaker (as shown in Figure 7).

SPX Expansion Bus
Up to two serial peripheral expansion (SPX) devices can be attached to the Lion at connector J17
using a VL-CBR-0901 cable. The SPX interface provides the standard serial peripheral interface
(SPI) signals: SCLK, MISO, and MOSI, as well as two chip selects, SS0# SS1#
The +5 V power provided to pin 1 of J17 is protected by a 1 A resettable fuse.
Interfaces and Connectors
37 Lion (VL-EPMe-42) Reference Manual
Table 23. SPX Expansion Bus Pinout
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 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 0.75 MHz and 6
MHz. Because this clock is divided from a 24Mhz LPC 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.

Thermal Considerations
This chapter discusses the following topics related to thermal issues:
Selecting the correct thermal solution for your application (begins below)
EPMe-42 thermal characterization (begins on page 42)
Installing the passive (HDW-406 heat sink) and active (HDW-413 fan) thermal solutions
available from VersaLogic (begins on page 45)
Selecting the Correct Thermal Solution for Your Application
This section provides guidelines for the overall system thermal engineering effort.
Heat Plate
The heat plate supplied with the Lion is the basis of the thermal solution. The heat plate draws
heat away from the CPU chip as well as other critical components such as the power supply /
management unit, the PCIe-to-PCI Bridge, and the Ethernet interfaces. Other components rely on
the ambient air temperature being maintained at or below the maximum specified 85ºC.
The heat plate is designed with the assumption that the user’s thermal solution will maintain the
top surface of the heat plate at 90 ºC or less. If that temperature threshold is maintained, the CPU
(and the other noted components) will remain safely within their operating temperature limits.
CAUTION:
By itself, the heat plate is not a complete thermal solution. Integrators should either implement a
thermal solution using the accessories available from VersaLogic or develop their own thermal
solution that attaches to the heat plate, suitable for environments in which the EPMe-42 will be
used. As stated above, any thermal solution must be capable of keeping the top surface of the
heat place at or below 90ºC and the air surrounding the components in the assembly at or below
85 ºC.
The heat plate is permanently affixed to the Lion and must not be removed. Removal of the heat
plate voids the product warranty. Attempting to operate the Lion without the heat plate voids the
product warranty and can damage the CPU.

Thermal Considerations
39 Lion (VL-EPMe-42) Reference Manual
System-level Considerations
The EPMe-42 thermal solutions either the HDW-406 heat sink alone or with the HDW-413 fan
are part of the larger thermal system of the application. Other PC/104 boards stacked under the
Lion and any other nearby heat sources (power supplies or other circuits), all contribute to how the
EPMe-42 will perform from a thermal standpoint.
The ambient air surrounding the EPMe-42 needs to be maintained at 85ºC or below. This can
prove to be challenging depending on how and where the EPMe-42 is mounted in the end user
system. Standard methods for addressing this requirement include the following:
Provide a typical airflow of 100 linear feet per minute (LFM) / 0.5 linear meters per second
(as described in the section titled EPMe-42 Thermal Characterization, beginning on page
42) within the enclosure
Position the EPMe-42 board to allow for convective airflow
Lower the system level temperature requirement as needed
The decision as to which thermal solution to use can be based on several factors including (but
not limited to) the following:
Number of CPU cores in the SoC (single, dual, or quad)
CPU core program utilization
Temperature range within which the EPMe-42 will be operated
Air movement (or lack of air movement)
Video processing intensity
Memory access demands
High speed I/O usage (PCIe, USB 3.0, SATA usage)
Most of these factors involve the demands of the user application on the EPMe-42 and cannot be
isolated from the overall thermal performance. Due to the interaction of the user application, the
Lion thermal solution, and the overall environment of the end system, thermal performance cannot
be rigidly defined.

Thermal Considerations
Lion (VL-EPMe-42) Reference Manual 40
CPU Thermal Trip Points
The CPU cores in the Lion have their own thermal sensors. Coupled with these sensors are
specific reactions to four thermal trip points. The table below describes the four thermal trip points.
Table 24. CPU Thermal Trip Points
Trip Point
Description
Active (Note 1) The fan is turned on when this temperature is reached
Passive (Note 2)
At this temperature, the CPU cores throttle back to a lower speed. This
reduces the power draw and the temperature.
Critical (Note 3)
At this temperature, the operating system typically puts the board into a
sleep or other low-power state.
Maximum core temperature
The CPU turns itself off when this temperature is reached. This is a fixed
trip point and cannot be adjusted.
Notes:
1. The default value in the BIOS Setup utility for this trip point is 55ºC.
2. The default value in the BIOS Setup utility for this trip point is 105ºC.
3. The default value in the BIOS Setup utility for this trip point is 110ºC.
These trip points allow maximum CPU operational performance while maintaining the lowest CPU
temperature possible. The long-term reliability of any electronic component is degraded when it is
continually run near its maximum thermal limit. Ideally, the CPU core temperatures would be kept
well below 100ºC with only brief excursions above.
CPU temperature monitoring programs are available to run under both Windows and Linux. The
table below lists some of these hardware monitoring programs.

Thermal Specifications, Restrictions, and Conditions
Graphical test data is in the section titled EPMe-42 Thermal Characterization, beginning on page
42. Refer to that section for the details behind these specifications. These specifications are the
thermal limits for using the EPMe-42 with one of the defined thermal solutions.
Due to the unknown nature of the entire thermal system, or the performance requirement of the
application, VersaLogic cannot recommend a particular thermal solution. This information is
provided for user guidance in the design of their overall thermal system solution.

Overall Restrictions and Conditions
Ranges shown assume less than 90% CPU utilization.
Keep the maximum CPU core temperature below 100ºC.
The ambient air surrounding the EPMe-42 needs to be maintained at 85ºC or below. This
includes the space between this CPU board and any board it is stacked on top of it.
Included is the space beneath an installed mini PCIe expansion board and the installed
SODIMM. A recommended overall air flow of 100 Linear Feet per Minute (LFM) / 0.5
Linear Meters per Second (LMS) addresses this requirement. If this air flow is not
provided, other means to keep the adjacent air at 85ºC or below must be implemented.
Heat Plate Only Restrictions and Conditions:
The heat plate must be kept below 90°C. This applies to a heat plate mounted directly to
another surface.
Heat Sink Only Considerations:
At 85°C air temperature and 90% CPU utilization, there will be little if any thermal
margin to a CPU core temperature of 100°C or the passive trip point (see test data). If this
is the use case, consider adding a fan or other additional air flow.
Heat Sink with Fan Considerations:
The heat sink and fan combination cools the CPU when it is running in high temperature
environments, or when the application software is heavily utilizing the CPU or video
circuitry. The fan assists in cooling the heat sink and provides additional air movement
within the system.
Integrator’s Note:
The ambient air surrounding the EPMe-42 needs to be maintained at 85ºC or below.

performance can be greatly enhanced by increasing the overall airflow beyond 0.5 meters per
second.
The system power dissipation is primarily dependent on the application program - that is, its use
of computing or I/O resources. The stress levels used in this testing are considered to be at the
top of the range of a typical users needs.
