Description
The high reliability design and construction of this board also features latching I/O connectors,
watchdog timer, voltage sensing reset circuit, and self-resetting fuse on the 5V supply to the
keyboard, mouse, and USB 1.1 ports. An onboard programmable CPU temperature sensor is
included for use in difficult thermal situations. The sensor output can be used to turn on
additional fans, create local or remote warnings, or take other action through software triggers.
The EPM-CPU-10 socket 370 compliant 2-board computer will accept Intel Flip-Chip Pentium
and Intel Flip-Chip Celeron Chips. Processors speeds up to 850 MHz are available.
This exceptional processor card was designed from the ground up for OEM applications with
longevity and reliability as the focus. It is fully supported by the VersaLogic design team. Both
hardware and software (BIOS) customization are available. Please contact a VersaLogic
Applications Support Specialist to discuss these requirements. Each board is subjected to a 48-
hour burn-in and 100% functional testing and backed by a limited two-year warranty.

Configuration / Operation
Overview
ELECTROSTATIC DISCHARGE
Warning! Electrostatic discharge (ESD) can damage boards, disk drives, and other
components. The circuit board must be 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 anti-static foam pad if
available.
The board should also be protected during shipment or storage by keeping inside a
closed metallic anti-static envelope.
Note! The exterior coating on some metallic anti-static bags is sufficiently conductive to
cause excessive battery drain if the bag comes in contact with the bottom side of
the EPM-CPU-10.
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.

Physical Dimensions
HARDWARE ASSEMBLY
The EPM-CPU-10 consists of two boards which are mounted together with eight 5mm x 15mm
M3 threaded hex male/female standoffs (p/n VL-HDW-101) using the corner mounting holes.
These standoffs are secured to the top circuit board using four pan head screws.
Caution Extreme care must be taken not to damage components near the corner mounting
holes when tightening standoffs with nut driver tools.
Additional PC/104-Plus or PC/104 cards can be attached to the bottom of the EPM-CPU-10
board set and secured with standoffs or 5mm nuts.
PC/104-Plus expansion modules can be secured directly to the underside of the EPM-CPU-10.
PC/104 expansion modules can be secured to the underside of the EPM-CPU-10, however, the
40-pin and 64-pin ISA feedthrough connectors may need to be extended, and longer standoffs
might need to be used to provide adequate clearance between the PCI connector and the
components on the top side of the PC/104 module.
The entire assembly can sit on a table top or it can 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. Refer to the drawing on page 9 for dimensional details.
An extractor tool is available (part number VL-HDW-201) to separate the modules from the
stack.
