Chapter 2 Introduction

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 appli­cations.

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.

(1)

Note:

 Operating: +5° to +55°C

 Non operating: -10° to +80°C

1 The 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 manu­facturer’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.

Chapter 6 ISA Bus Expansion

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.

Chapter 7 Graphics Interface

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).

Chapter 15 Power Connector

15. Power Connector

In some applications, the PC/104-520 is intended for use as a stand-alone module without a backplane. You
need to have a power connector available on the board for direct power supply. The PC/104-520 is a +5V
only board. Peripherals can obtain additional voltage from the power connector next to the PC/104 bus. The
additional voltages (+12V, -5V and -12V) are not generated onboard the PC/104-520.

15.1 Connector

The pinout of the power connector P6 (8 pins) is shown in the table below.

To find the location of the power connector on the PC/104-520 board, please see the Appendix “Connector
Layout”.

15.2 Power Pins

Every power pin on the power connector as well as on the PC/104 bus connector is limited to a maximum
current of 1A per pin.

If a system using a PC/104-520 is only supplied from the power connector, the following limitations apply:

Power Number of Pins Max. Current

VCC (+5V) 2 2A

+12V 1 1A

-12V 1 1A
GND 2 2A

Kontron User's Guide PC/104-520

29

Chapter 15 Power Connector

A system using the PC/104-520 also can be supplied from the PC/104 bus connectors. If only those supply
voltages pins are used, the following limitations apply:

Power Number of Pins on

Max. Current

ISA Part

VCC (+5V) 4 4A

+12V 2 2A

-12V 2 2A
GND 8 8A

Modules on the PC/104 bus consuming a higher supply current must provide power supply through an
additional connector.

Note: The PC/104-520 is not a replacement for a backplane. Use all power pins on the power connector and on the

PC/104 connectors for power supply to the PC/104-520, and also use all additional power connectors on addi­tional I/O cards if your system exceeds the above limitations. It is not acceptable to use only the power pins of
the PC/104 connector for power supply to the full PC/104 stack.

15.3 External Battery

You can connect an external battery to Pin 3 (BATT) of the power connector instead of Pin 9 of the KBD
connector. For more information refer to the Keyboard chapter of this manual.

Note: Pin 3 (power connector) and Pin 9 (KBD connector) are connected to the same signal. The pins are not de-

coupled, therefore do not connect two batteries.

When CMOS memory (containing your system's configuration) is erased, the CPU is reset to the delivery de­fault. Hint: the flash memory (including a copy of the CMOS memory) is not affected by this operation.

Chapter 16 Watchdog Timer

16. Watchdog Timer

The watchdog timer (WDT) is integrated in the Winbond W83977F controller of the PC/104-520 and can
issue a reset to the system. The watchdog timer circuit has to be triggered within a specified time by the
application software. If the watchdog timer is not triggered because proper software execution fails or a
hardware malfunction occurs, it resets the system.

16.1 Programming

16.1.1 Initialization

You can initialize the watchdog timer from the application software (sourcecode on request) or BIOS setup.
Setup option uses a fixed timeout period of 32 seconds.

Likewise a JIDA call (INT 15h) is available. Register values:

AX = 0E000h
BX = 0h  Watchdog off / BX = 1h  timeout 1 sec. / BX = 2h  2 sec. / BX = 3h  4 sec.
BX = 4h  8 sec. / BX = 5h  16 sec. / BX = 6h  32 sec.
CX = 0h
DX = 0h

16.1.2 Trigger

The watchdog needs to be triggered out of the application software within a specified timeout period. You
can only do this in the application software by using low-level programming.

Likewise a JIDA call (INT 15h) is available. Register values:

AX = 0E001h
BX = CX = DX = 0h

16.1.3 Utility SC520Wdt

SC520Wdt is a program to activate, deactivate and trigger the watchdog. Syntax:

19.10 Kontron BIOS Extensions

Besides the INSYDE System BIOS, the PC/104-520 comes with a few BIOS extensions that support special
features. All extensions are located in the onboard Flash. Some extensions are permanently available; some
are active during boot-up.

Supported features include:

 JIDA standard (only JIDA16)

 Remote Control feature (special protocol, not JRC)

19.10.1 JIDA BIOS Extension

The JUMPtec Intelligent Device Architecture (JIDA) interface is integrated into the BIOS of the PC/104-520
module. This interface enables hardware-independent access to features that cannot be accessed via
standard APIs.

The JIDA BIOS extension is not a true extension BIOS. It is part of the system BIOS and is located in the
system BIOS segments after boot-up. It is permanently available and supports the JIDA 16-bit standard.

The JIDA 16-bit standard is a software interrupt 15h driven interface for programmers and offers lots of
board information functions. For detailed information about programming, refer to the JIDA specification
and a source code example (JIDAI???.ZIP), which you can find on the Kontron Website. The three question
marks represent the revision number of the file. You also can contact technical support for this file.

19.10.2 Remote Control Client Extension

You can remotely control the PC/104-520 using software available from Kontron. This software tool can
communicate with the board via one of the serial or the parallel port. During boot-up, the system BIOS
scans the ports for an available connection. If detected, it starts the remote session.

The connection between the target system (PC/104-520) and the host (Desktop PC) occurs over the serial or
parallel port via a special cable:

A.1 Interrupt Request Lines

Please note that Kontron PC/104 devices were designed after the draft of P996 Specification for ISA
systems. Because of this, shareable interrupts are not supported. Some PC/104 add-on board manu­facturers do not follow the P996 Specification and allow shareable interrupts. If you want to use such
PC/104 boards with Kontron devices, contact the manufacturer of the add-on board and ask about switching
to non-interrupt sharing. Please ensure that the chosen interrupt is not already in use by a PCI device.
