2.2 PC/104 an Embedded PC Standard
By standardizing hardware and software around the broadly supported PC architecture, embedded system
designers can substantially reduce development costs, risks, and time-to-market.
For these reasons, companies that embed microcomputers as controllers within their products seek ways to
reap the benefits of using the PC architecture. However, the standard form factor of a PC bus (12.4” x 4.8”)
and its associated card cages and backplanes are too bulky and expensive for most embedded control appli-
cations.
The only practical way to embed the PC architecture in space and power sensitive applications has been to
design a PC chip by chip directly into the product. But this runs counter to growing trend away from
“reinventing the wheel.” Whenever possible, management encourages outsourcing of components and
technologies to reduce development costs and accelerate product design cycles.
A need has arisen for a more compact implementation of the PC bus, satisfying the reduced space and power
constraints of embedded control applications. PC/104 was developed in response to this need. It offers full
architecture, hardware and software compatibility with the PC bus but in ultra-compact (3.6” x 3.8”)
stackable modules. PC/104 is ideally suited to the unique requirements of embedded control applications.
Although configuration and application possibilities with PC/104 modules are practically limitless, there are
two ways to use them in embedded system designs:
Standalone module stacks
PC/104 modules are self-stacking. The modules are used like ultra-compact bus boards
but do not need backplanes or card cages.
Component line applications
In this configuration, the modules function as highly integrated components, plugged
into custom carrier boards that contain application specific interfaces and logic.

4.4 Environmental Specifications
4.4.1 Temperature
The AMD SC520 is specified for proper operation when case temperature is within the specified range of
+5°C to +85°C.
Operating: +5° to +55°C (1)
Non operating: -10° to +80°C
Note: 1The maximum operating temperature is the maximum measurable temperature on any spot on a module’s
surface. You must maintain the temperature according to the above specification.
4.4.2 Humidity
Operating: 10% to 90% (non condensing)
Non operating: 5% to 95% (non condensing)
4.5 MTBF
The following MTBF (Mean Time Between Failure) values were calculated using a combination of manu-
facturer’s test data, if the data was available, and a Bellcore calculation for the remaining parts. The
Bellcore calculation used is “Method 1 Case 1”. In that particular method the components are assumed to be
operating at a 50% stress level in a 40°C ambient environment and the system is assumed to have not been
burned in. Manufacturer’s data has been used wherever possible. The manufacturer’s data, when used, is
specified at 50°C, so in that sense the following results are slightly conservative. The MTBF values shown
below are for a 40°C in an office or telecommunications environment. Higher temperatures and other
environmental stresses (extreme altitude, vibration, salt water exposure, etc.) lower MTBF values.
System MTBF (hours) : tbd
Note: Fans usually shipped with Kontron Embedded Modules GmbH products have 50,000-hour typical operating life.
The above estimates assume no fan, but a passive heat sinking arrangement. Estimated RTC battery life (as
opposed to battery failures) is not accounted for in the above figures and need to be considered for
separately. Battery life depends on both temperature and operating conditions. When the Kontron unit has
external power; the only battery drain is from leakage paths.

6. ISA Bus Expansion
The design of the PC/104-520 follows the standard PC/104 form factor and offers ISA bus signals for the use
of standard PC/104 adapter cards.
6.1 PC/104 Bus (ISA part)
The PC/104 bus consists of two connectors that use 104 pins in total.
XT bus connector (64 pins)
AT bus connector (40 pins, which is optional for 16 bit data bus system)
The pinout of the PC/104 bus connectors corresponds to the pinout of the ISA bus connectors with some
added ground pins. The two PC systems with different form factors are electrically compatible.
The XT bus connector, Row A and B.
The corresponding 64-pin stackthrough header (ISA bus = 62pins) has two added ground pins at the end of
the connector (Pin A32 and Pin B32). The pinout between PC/104 bus and XT ISA bus is identical between
A1 - A31 and B1 - B31.
The AT bus extension connector, Row C and D.
The corresponding 40-pin stackthrough header (ISA bus = 36 pins) has four added ground pins, two on each
side of the connector. To avoid confusion, the first two pins are defined as Pin C0 and Pin D0. The additional
ground pins at the end of the connector are defined as C19 and D19. The pinout between PC/104 bus and AT
ISA bus is identical between C1 - C18 and D1 - D18.
6.1.1 PC/104 Connectors
The PC/104-520 features both – XT bus and AT bus extension – on two, dual-row socket connector with
2.54mm x 2.54mm grid (0.1” x 0.1”).
The PC/104 XT bus is available through the X4B connector. The PC/104 AT bus is available through the X4C
connector.
A detailed description of the signals including electrical characteristics and timings is beyond the scope of
this document. Please refer to the official ISA bus and PC/104 specifications for more details.
6.1.2 PC/104 Configuration
When using add-on boards on the PC/104 bus, make sure that there are no resource conflicts in the system.
Carefully choose hardware interrupts, DMA channels, memory and I/O address ranges to avoid resource
conflicts, which are often the reason for a board or a feature not functioning correctly.
PC/104 adapter cards are mounted in a stack-through manner. Adapter cards are designed with plugs on
their undersides that mate with the PC/104 socket connectors of PC/104-520. PC/104 adapters can support
the socket connector version on their topside and allow additional stacking of adapters.
Whenever possible use the PC/104-520 as top module of the PC/104 stack as the CPU board is normally the
board with the highest heat dissipation.

7. Graphics Interface
The graphics controller supports CRT monitors and a variety of LCD panels with single or double clock, color
depths of 18/24 bit and resolutions up to XGA (1024x768).
7.1 CRT Connector
The CRT monitor interface is available through the J4 connector (10 pins). To have the signals available on a
standard DSUB-15 CRT monitor connector, an adapter cable is required. A 15-pin DSUB cable is available
from Kontron (KAB-PC104520-VGA, Part Number 96229-0200-00-0).

7.2 LCD Panel Connector
The interface for the LCD Panel is available through the J3 connector (50 pins) on the top side of the board.
Detailed information about available panel cables on request.
When using a LCD Panel, additional voltages may be required to drive the display’s logic and to supply the
backlight converter. The display logic may require +5V for standard or +3.3V for low-power LCDs. The on-
board 3.3V-circuitry of the PC/104-520 and the +3.3V logic voltage of low-voltage panels are share the
same voltage regulators.
To find the location of the LCD Panel interface connector on the PC/104-520 board, please see the Appendix
“Connector Layout”.
Note: You need to supply the +12V for the backlight converter additionally when using such a converter type.

7.3 Connecting a LCD Panel
To determine whether your panel display is supported, check the Kontron Website for panel lists. We regu-
larly update the list of panels that have been tested with the PC/104-520.
If you use one of those cables supplied by Kontron, configuration is easy:
Check whether you have the correct cable for the panel you plan to use. Inspect the cable for
damages. Disconnect the power from your system.
Check Jumper J16 for correct Panel voltage (J16 1-2 = 5V 2-3 = 3.3V). Hint: J16 1-2 default.
