1.10. For Your Safety

Your new DIGITAL-LOGIC product was developed and tested carefully to provide all features

necessary to ensure its compliance with electrical safety requirements. It was also designed for a

long, fault-free life. However, this life expectancy can be drastically reduced by improper treatment

during unpacking and installation. Therefore, in the interest of your own safety and for the correct

operation of your new DIGITAL-LOGIC product, please comply with the following guidelines.

Attention!

All work on this device must only be carried out by sufficiently skilled personnel.

Caution, Electric Shock!

Before installing your new DIGITAL-LOGIC product, always ensure that your mains power is

switched off. This applies also to the installation of piggybacks or peripherals. Serious

electrical shock hazards can exist during all installation, repair and maintenance operations

with this product. Therefore, always unplug the power cable and any other cables which

provide external voltage before performing work.

Warning, ESD Sensitive Device!

Electronic boards and their components are sensitive to static electricity. In order to ensure

product integrity at all times, be careful during all handling and examinations of this product.

1.11. RoHS Commitment

DIGITAL-LOGIC AG is committed to develop and produce environmentally friendly products according to the

Restriction of Hazardous Substances (RoHS) Directive (2002/95/EC) and the Waste Electrical and Electronic

Equipment (WEEE) Directive (2002/96/EC) established by the European Union. The RoHS directive was

adopted in February 2003 by the European Union and came into effect on July 1, 2006. It is not a law but a

directive, which restricts the use of six hazardous materials in the manufacturing of various types of

electronic and electrical equipment. It is closely linked with the Waste Electrical and Electronic Equipment

Directive (WEEE) 2002/96/EC, which has set targets for collection, recycling and recovery of electrical goods

and is part of a legislative initiative to solve the problem of huge amounts of toxic e-waste.

Each European Union member state is adopting its own enforcement and implementation policies using the

directive as a guide. Therefore, there could be as many different versions of the law as there are states in

the EU. Additionally, non-EU countries like China, Japan, or states in the U.S. such as California may have

their own regulations for green products, which are similar, but not identical, to the RoHS directive.

DIGITAL-LOGIC AG MSM855/HLV/B/B2 Detailed Manual V1.0A

RoHS is often referred to as the "lead-free" directive but it restricts the use of the following substances:

 Lead

 Mercury

 Cadmium

 Chromium VI

 PBB and PBDE

The maximum allowable concentration of any of the above mentioned substances is 0.1% (except for

Cadmium, which is limited to 0.01%) by weight of homogeneous material. This means that the limits do not

apply to the weight of the finished product, or even to a component but to any single substance that could

(theoretically) be separated mechanically.

1.11.1. RoHS Compatible Product Design

All DIGITAL-LOGIC standard products comply with RoHS legislation.

Since July 1, 2006, there has been a strict adherence to the use of RoHS compliant electronic and

mechanical components during the design-in phase of all DIGITAL-LOGIC standard products.

1.11.2. RoHS Compliant Production Process

DIGITAL-LOGIC selects external suppliers that are capable of producing RoHS compliant devices. These

capabilities are verified by:

1. A confirmation from the supplier indicating that their production processes and resulting devices are

RoHS compliant.

2. If there is any doubt of the RoHS compliancy, the concentration of the previously mentioned

substances in a produced device will be measured. These measurements are carried out by an

accredited laboratory.

1.11.3. WEEE Application

The WEEE directive is closely related to the RoHS directive and applies to the following devices:

 Large and small household appliances

 IT equipment

 Telecommunications equipment (although infrastructure equipment is exempt in some countries)

 Consumer equipment

 Lighting equipment – including light bulbs

 Electronic and electrical tools

 Toys, leisure and sports equipment

 Automatic dispensers

It does not apply to fixed industrial plants and tools. The compliance is the responsibility of the company that

brings the product to market, as defined in the directive. Components and sub-assemblies are not subject to

product compliance. In other words, since DIGITAL-LOGIC does not deliver ready-made products to end

users the WEEE directive is not applicable for DIGITAL-LOGIC. Users are nevertheless encouraged to

properly recycle all electronic products that have reached the end of their life cycle.

2.7. MSM855/B/B2 Incompatibilities to a standard PC/AT

2.7.1. MSM855 / HLV

On the Intel855GME Design and in the PC-03 specification, no ISA-Bus is available. For the BIOS and the

SuperIO functions, the LPC-Bus is integrated. The LPC-Bus is a serialized ISA-Bus with some limitations.

Onboard is an LPC to ISA-Bridge integrated to generate a standard ISA-Bus. In using the combination of the

LPC-Bus and the LPC-Bridge there are some incompatibilities.

The LPC support the following bus cycles:

This means that all non-Busmaster I/Os and MEM Cycles are only 8bit wide and never 16bit wide. 16bit data

transfer is available in the BusMaster modus only.

2.7.2. ISA-Incompatibilitiy with ISA-PCCARD-Controller

Experience shows that ATA-Drives controlled in an ISA-PCMCIA Controller do not work.

Solution: Use a PCCARD-Controller on the PCI-Bus.

DIGITAL-LOGIC AG MSM855/HLV/B/B2 Detailed Manual V1.0A

2.7.3. ISA-Incompatibilitiy with 16bit I/O Transfer with FPGA-Decoder

Our experience shows that 16bit I/O-transfers decoded with an FPGA do not always work correct. Each case

must be tested..

Solution: Use two 8bit transfers instead one 16bit transfer. For time critical transfers we recommend using

the PCI-Bus.

2.7.4. ISA-Incompatibilitiy with 16bit Memory Transfer with FPGA-

Decoder

Experience shows that 16bit Memory-transfers decoded with an FPGA do not always work correctly. Each

case must be tested. Expect problems on odd addresses.

Solution: Use two 8bit transfers instead of one 16bit transfer. For time critical transfers we recommend

using the PCI-Bus.

2.10. High Frequency Radiation (to meet EN55022/EN61000)

Since the PC/104 CPU modules are very highly integrated embedded computers, peripheral lines are not

protected against radiation from the high frequency spectrum. To meet a typical EN55022 requirement, all

peripherals that go outside of the computer case must be externally filtered.

Typical signals that must be filtered:

Keyboard: KBCLK, KBDATA, VCC

Mouse: MSCLK, MSDATA, VCC

COM1/2/3/4: All serial signals must be filtered

LPT: All parallel signals must be filtered

CRT: Red, blue, green, hsynch and vsynch must be filtered

Typical signals that must not be filtered, since they are used internally:

IDE: Connected to the hard disk

Floppy: Connected to the floppy

LCD: Connected to the internal LCD

2.10.1. For Peripheral Cables:

Use a filtered version for all DSUB connectors. Select the filter specifications carefully. Place the filtered

DSUB connector directly on the front side and be sure that the shielding makes good contact with the case.

9pin DSUB connector from AMPHENOL: FCC17E09P 820pF

25pin DSUB connector from AMPHENOL: FCC17B25P 820pF

2.10.2. For Stack-Through Applications:

On each peripheral signal line that goes outside the computer case, place a serial inductivity followed by a

grounded capacitor of 100pF to 1000pF. In this case, no filtered connectors are needed. Place the filter

directly under or behind the onboard connector.

Serial Inductivity: TDK HF50ACB321611-T 100Mhz, 500mA, 1206 Case

Ground capacitor: Ceramic Capacitor with 1000pF

2.10.3. Power Supply:

Use a current-compensated dual inductor on the 5V supply.

For more information, please see Section 5.1.

2.11. RTC Battery Lifetime

An AT compatible date/time clock is located within the chipset. The device also contains a CMOS static RAM

compatible with that in standard ATs. System configuration data is normally stored in the clock chip's CMOS

RAM in a manner consistent with the convention used in other AT compatible computers.

There are two ways to connect an external 3.6V lithium battery.

1. The most commonly used connection:

MSM855

The LAN-adaptor includes the LAN-transformer and the lithium battery. We recommend connecting

the battery to J29 , the universal LAN-Adaptor-Connector. The LAN-adaptor and the LAN-cable are

included.

MSM855B/B2

There is an onboard battery socket for a BR1225.

2. Alternative connection:

Keyboard connector J8 (pin8 = battery 3.6V input, pin7 = GND).

If the the battery is connected to J8, the J29 must not be used to connect the RTC-battery.

The battery-backed clock may be set during the boot process by using DIGITAL-LOGIC's setup.

(inclusive of the diode which is already assembled onboard).

DIGITAL-LOGIC AG MSM855/HLV/B/B2 Detailed Manual V1.0A

3. CHIPSET DESCRIPTION

3.1. INTEL Processor Pentium-M

The Intel® Pentium® M processor is a high-performance, low-power mobile processor with several micro-

architectural enhancements over existing Intel mobile processors.

The following is a list of some of the key features on this processor:

 Supports Intel® Architecture with Dynamic Execution

 High-performance, low-power core

 On-die, primary 32kByte instruction cache and 32kByte write-back data cache

 On-die, 1/2MByte 2nd level cache with Advanced Transfer Cache Architecture

 Advanced Branch Prediction and Data Prefetch Logic

 Streaming SIMD Extensions 2 (SSE2)

 400/533MHz, source-synchronous processor system bus

 Advanced Power Management features including Enhanced Intel® SpeedStep® technology

 Micro-FCPGA and Micro-FCBGA packaging technologies

The Intel Pentium M processor is manufactured on Intel’s advanced 0.13/0.09 micron process technology

with copper interconnect. The processor maintains support for MMX™ technology and Internet Streaming

SIMD instructions and full compatibility with IA-32 software. The high-performance core features architectural

innovations like Micro-op Fusion and Advanced Stack Management that reduce the number of micro-ops

handled by the processor. This results in more efficient scheduling and better performance at lower power.

The on-die 32kB Level 1 instruction and data caches and the 1MB Level 2 cache with Advanced Transfer

Cache Architecture enable significant performance improvement over existing mobile processors. The

processor also features a very advanced branch prediction architecture that significantly reduces the number

of mispredicted branches. The processor’s Data Prefetch Logic speculatively fetches data to the L2 cache

before an L1 cache requests occurs, resulting in reduced bus cycle penalties and improved performance.

The Streaming SIMD Extensions 2 (SSE2) enable break-through levels of performance in multimedia

applications including 3-D graphics, video decoding/encoding, and speech recognition. The new packed

double-precision floating-point instructions enhance performance for applications that require greater range

and precision, including scientific and engineering applications and advanced 3-D geometry techniques,

such as ray tracing.

The Intel Pentium M processor’s 400MHz processor system bus utilizes a split-transaction, deferred reply

protocol. The 400MHz processor system bus uses Source-Synchronous Transfer (SST) of address and data

to improve performance by transferring data four times per bus clock (4X data transfer rate, as in AGP 4X).

Along with the 4X data bus, the address bus can deliver addresses two times per bus clock and is referred to

as a “double-clocked” or 2X address bus. Working together, the 4X data bus and 2X address bus provide a

data bus bandwidth of up to 3.2GBytes/second. The processor system bus uses Advanced Gunning

Transceiver Logic (AGTL+) signal technology, a variant of GTL+ signalling technology with low power

enhancements.

Note: The term AGTL+ has been used for Assisted Gunning Transceiver Logic technology on other Intel

products.

DIGITAL-LOGIC AG MSM855/HLV/B/B2 Detailed Manual V1.0A

3.1.1. Introduction

The processor features Enhanced Intel SpeedStep technology, which enables real-time dynamic switching

between multiple voltage and frequency points instead of two points supported on previous versions of Intel

SpeedStep technology. This results in optimal performance without compromising low power. The processor

features the Auto Halt, Stop-Grant, Deep Sleep, and Deeper Sleep low-power states. The Intel Pentium M

processor utilizes socket-able Micro Flip-Chip Pin Grid Array (Micro-FCPGA) and surface mount Micro Flip-

Chip Ball Grid Array (Micro-FCBGA) package technology. The Micro-FCPGA package plugs into a 479-hole,

surface-mount, Zero Insertion Force (ZIF) socket, which is referred to as the mPGA479M socket.

This document includes specifications for the Intel Pentium M processor at Highest Frequency Mode (HFM)

core frequencies of 1.30, 1.40, 1.50, and 1.60GHz, the Low Voltage Intel Pentium M processor at HFM core

frequency of 1.10GHz and the Ultra Low Voltage Intel Pentium M processor at HFM core frequency of

900MHz.

3.1.2. Deep Sleep State

Deep Sleep state is a very low power state the processor can enter while maintaining context. Deep Sleep

state is entered by asserting the DPSLP# pin while in the Sleep state. BCLK may be stopped during the

Deep Sleep state for additional platform level power savings. BCLK stop/restart timings on Intel 855PM and

Intel 855GME chipset-based platforms are as follows:

Intel® Pentium® M Processor Datasheet 14

3.1.3. Low Power Features

 Deep Sleep entry - DPSLP# and CPU_STP# are asserted simultaneously. The platform clock chip will

stop/tristate BCLK within 2 BCLKs +/- a few nanoseconds.

 Deep Sleep exit - DPSLP# and CPU_STP# are deasserted simultaneously. The platform clock chip

will drive BCLK to differential DC levels within 2-3 ns and starts toggling BCLK 2-6 BCLK periods later.

To re-enter the Sleep state, the DPSLP# pin must be deasserted. BCLK can be re-started after DPSLP#

deassertion as described above. A period of 30 microseconds (to allow for PLL stabilization) must occur

before the processor can be considered to be in the Sleep state. Once in the Sleep state, the SLP# pin must

be deasserted to re-enter the Stop-Grant state. While in Deep Sleep state, the processor is incapable of

responding to snoop transactions or latching interrupt signals. No transitions of signals are allowed on the

system bus while the processor is in Deep Sleep state. Any transition on an input signal before the processor

has returned to Stop-Grant state will result in unpredictable behavior.

3.1.4. Deeper Sleep State

The Deeper Sleep state is the lowest power state the processor can enter. This state is functionally identical

to the Deep Sleep state but at a lower core voltage. The control signals to the voltage regulator to initiate a

transition to the Deeper Sleep state are provided on the platform. Please refer to the platform design guides

for details.

DIGITAL-LOGIC AG MSM855/HLV/B/B2 Detailed Manual V1.0A

3.1.5. Enhanced Intel® SpeedStep® Technology

(only available with Pentium-M CPUs, not with Celeron-M CPUs)

The Intel Pentium M processor features Enhanced Intel SpeedStep® technology. Unlike previous

implementations of Intel SpeedStep, this technology enables the processor to switch between multiple

frequency and voltage points instead of two. This enables superior performance with optimal power savings.

Switching between states is software controlled unlike previous implementations where the GHI# pin was

used to toggle between the two states.

The key features of Enhanced Intel SpeedStep technology are:

 Multiple voltage/frequency operating points provide optimal performance at the lowest power.

 Voltage/Frequency selection is software controlled by writing to processor MSR’s (Model Specific

Registers) thus eliminating chipset dependency.

o If the target frequency is higher than the current frequency, Vcc is ramped up by placing a new

value on the VID pins and the PLL then locks to the new frequency.

o If the target frequency is lower than the current frequency, the PLL locks to the new frequency

and the Vcc is changed through the VID pin mechanism.

o Software transitions are accepted at any time. If a previous transition is in progress, the new

transition is deferred until its completion.

 The processor controls voltage ramp rates internally to ensure glitch free transitions.

 Low transition latency and large number of transitions possible per second.

o Processor core (including L2 cache) is unavailable for up to 10 µs during the frequency transition

o The bus protocol (BNR# mechanism) is used to block snooping

Low Power Features:

 No bus master arbiter disable required prior to transition and no processor cache flush necessary.

 Improved Intel Thermal Monitor mode.

o When the on-die thermal sensor indicates that the die temperature is too high, the processor can

automatically perform a transition to a lower frequency/voltage specified in a software

programmable MSR.

o The processor waits for a fixed time period. If the die temperature is down to acceptable levels, an

up transition to the previous frequency/voltage point occurs.

o An interrupt is generated for the up and down Intel Thermal Monitor transitions enabling better

system level thermal management.

Enhancements:

 Dynamic PSB Power Down

 BPRI# control for address and control input buffers

 Dynamic On Die Termination disabling

 Low VCCP (I/O termination voltage) switching power at all times monitoring requirements in the

Deeper Sleep state.

3.2. Graphic-Memory-Control Hub: INTEL 855GME

3.2.1. Processor Host Interface

The GMCH is optimized for the Intel Pentium M processor. Key features of the Intel Pentium M processor

system bus (PSB) are:

 Source synchronous double-pumped address.

 Source synchronous quad-pumped data.

 System bus interrupt delivery.

 Low voltage swing (Vtt = 1.05 V).

 Dynamic Power Down (DPWR#) support.

 GMCH supports a 64-B cache line size.

 Support for a 400MHz system bus frequency. Dual processor is not supported.

 Integrates AGTL+ termination resistors on all of the AGTL+ signals.

 Supports 64bit host bus addressing allowing the CPU to access the entire 4GB of the GMCH

memory address space.

 A 12-deep, In-Order queue to support up to twelve outstanding pipelined address requests on the

host bus.

 Drives DPWR# signal to the processor, which can then disable its sense amplifiers.

 Supports only one outstanding defer cycle at a time to any particular I/O interface.

 Host initiated I/O cycles are positively decoded to the GMCH configuration space and subtractively

decoded to the Hub Interface

 Host initiated memory cycles are positively decoded to DDR SDRAM.

 Memory accesses initiated from the Hub Interface to DDR SDRAM will be snooped on the system

bus.

3.2.2. Intel 855GME GMCH Host Bus Error Checking

The Intel 855GME GMCH does not generate, nor check, parity on Data, Address/Request, and Response

signals on the PSB.

3.2.3. Intel 855GME GMCH System Memory Interface

The GMCH System Memory Controller directly supports the following:

 One channel of PC1600/2100 SO-DIMM DDR SDRAM memory.

 DDR SDRAM devices with densities of 128, 256 and 512MB technology.

 Maximum System Memory with two, double-sided SO-DIMMs (four rows populated) supporting up

to 1GB system memory, and high density supporting up to 2GB system memory.

 Variable page sizes of 2, 4, 8 and 16kB. Page size is individually selectable for every row and a

maximum of 16 pages may be opened simultaneously

The GMCH System Memory interface supports a thermal throttling scheme to selectively throttle reads

and/or writes. Throttling can be triggered either by the on-die thermal sensor, or by preset write bandwidth

limits. Read throttle can also be triggered by an external input pin. The memory controller logic supports

aggressive Dynamic Row Power Down features to help reduce power and supports Address and Control line

Tri-stating when DDR SDRAM is in an active power-down or in self-refresh state. The GMCH System

Memory architecture is optimized to maintain open pages (up to 16kB page size) across multiple rows. As a

result, up to 16 pages across four rows is supported. To complement this, the GMCH will tend to keep pages

open within rows, or will only close a single bank on a page miss. The GMCH supports only four bank

memory technologies.

DIGITAL-LOGIC AG MSM855/HLV/B/B2 Detailed Manual V1.0A

3.2.4. Intel 855GME GMCH Internal Graphics

The GMCH IGD provides a highly integrated graphics accelerator delivering high performance 2D, 3D, and

video capabilities. With its interfaces to UMA using a DVMT configuration, an analog display, a LVDS port,

and two digital display ports (e.g., flat panel), the GMCH can provide a complete graphics solution.

The GMCH also provides 2D hardware acceleration for block transfers of data (BLTs). The BLT engine

provides the ability to copy a source block of data to a destination and perform raster operations (e.g.,

ROP1, ROP2, and ROP3) on the data using a pattern, and/or another destination. Performing these

common tasks in hardware reduces CPU load, and thus improves performance. High bandwidth access to

data is provided through the System Memory interface. The GMCH uses Tiling architecture to increase

System Memory efficiency and thus maximize effective rendering bandwidth. The Intel 855GME GMCH also

improves 3D performance and quality with 3D Zone Rendering technology.

The GMCH has four display ports, one analog and three digital. These provide support for a progressive

scan analog monitor, a dedicated dual channel LVDS LCD panel, and two DVO devices. Each port can

transmit data according to one or more protocols. The DVO ports are connected to an external device that

converts one protocol to another. Examples of this are TV-out encoders, external DACs, LVDS transmitters,

and TMDS transmitters. Each display port has control signals that may be used to control, configure and/or

determine the capabilities of an external device. The data that is sent out the display port is selected from

one of the two possible sources, Pipe A or Pipe B.

3.2.5. Intel 855GME GMCH Analog Display Port

Intel 855GME GMCH has an integrated 350MHz, 24bit RAMDAC that can directly drive a progressive scan

analog monitor pixel resolution up to 2048x1600 at 85Hz refresh and up to 2048x1536 at 72Hz refresh. The

analog display port can be driven by Pipe A or Pipe B.

3.2.6. Intel 855GME GMCH Integrated DVO Ports

The DVO B/C interface is compliant with the DVI Specification 1.0. When combined with a DVI compliant

external device (e.g., TMDS Flat Panel Transmitter, TV-out encoder, etc.), the GMCH provides a high-speed

interface to a digital or analog display (e.g., flat panel, TV monitor, etc.).

The GMCH provides two DVO ports that are each capable of driving a 165MHz pixel clock at the DVO B or

DVO C interface. When DVO B and DVO C are combined into a single DVO port, then an effective pixel rate

of 330MHz can be achieved. The DVO B/C ports can be driven by Pipe A or Pipe B. If driven on Pipe B, then

the LVDS port must be disabled.

3.2.7. Hub Interface

A proprietary interconnect connects the GMCH to the ICH4-M. All communication between the GMCH and

the ICH4-M occurs over the Hub Interface 1.5. The Hub Interface runs at 66MHz (266MB/s).

3.2.8. Address Decode Policies

Host initiated I/O cycles are positively decoded to the GMCH configuration space and subtractively decoded

to the Hub Interface. Host initiated System Memory cycles are positively decoded to DDR SDRAM and are

again subtractively decoded to the Hub Interface if under 4GB. System Memory accesses from the Hub

Interface to DDR SDRAM will be snooped on the PSB.

4. BUS SIGNALS

4.1. PC104 Bus

Note...

Not all of the signals are available on this board (please see Chapter 6 for a description of

the connectors).

AEN, output

Address Enable: used to degate the microprocessor and other devices from the I/O channel to allow

DMA transfers to take place. low = CPU Cycle, high = DMA Cycle

BALE, output

Address Latch Enable: provided by the bus controller and used on the system board to latch valid

addresses and memory decodes from the microprocessor. This signal is used so that devices on the

bus can latch LA17-23. The SA0-19 address lines latch internally according to this signal. BALE is

forced high during DMA cycles.

/DACK[0, 5-7], output

DMA Acknowledge: 0 to 3 and 5 to 7 are used to acknowledge DMA requests (DRQO through DRQ7).

They are active low. This signal indicates that the DMA operation can begin.

DRQ[0, 5-7], input

DMA Requests: 0 through 3 and 5 through 7 are asynchronous channel requests used by peripheral

devices and the I/O channel microprocessors to gain DMA service (or control of the system). A

request is generated by bringing a DRQ line to an active level. A DRQ line must be held high until the

corresponding DMA Request Acknowledge (DACK/) line goes active. DRQO through DRQ3 will

perform 8bit DMA transfers; DRQ5-7 are used for 16 accesses.

/IOCHCK, input

IOCHCK/: provides the system board with parity (error) information about memory or devices on the

I/O channel. low = parity error, high = normal operation

IOCHRDY, input

I/O Channel Ready: pulled low (not ready) by a memory or I/O device to lengthen I/O or memory

cycles. Any slow device using this line should drive it low immediately upon detecting its valid address

and a Read or Write command. Machine cycles are extended by an integral number of one clock cycle

(67 nanoseconds). This signal should be held in the range of 125-15600nS. low = wait, high =

normal operation

/IOCS16, input

I/O 16 Bit Chip Select: signals the system board that the present data transfer is a 16bit, 1 wait-state,

I/0 cycle. It is derived from an address decode. /IOCS16 is active low and should be driven with an

open collector (300 ohm pull-up) or tri-state driver capable of sinking 20mA. The signal is driven based

only on SA15-SAO (not /IOR or /IOW) when AEN is not asserted. In the 8bit I/O transfer, the default

transfers a 4 wait-state cycle.

/IOR, input/output

I/O Read instructs an I/O device to drive its data onto the data bus. It may be driven by the system

microprocessor or DMA controller, or by a microprocessor or DMA controller resident on the I/O

channel. This signal is active low.

/IOW, input/output

I/O Write: instructs an I/O device to read the data on the data bus. It may be driven by any

microprocessor or DMA controller in the system. This signal is active low.

DIGITAL-LOGIC AG MSM855/HLV/B/B2 Detailed Manual V1.0A

IRQ [10, 12, 14, 15], input

These signals are used to tell the microprocessor that an I/O device needs attention. An interrupt

request is generated when an IRQ line is raised from low to high. The line must be held high until

the microprocessor acknowledges the interrupt request.

/Master, input

This signal is used with a DRQ line to gain control of the system. A processor or DMA controller on the

I/0 channel may issue a DRQ to a DMA channel in cascade mode and receive a /DACK.

/MEMCS16, input

MEMCS16 Chip Select: signals the system board if the present data transfer is a 1 wait-state, 16bit,

memory cycle. It must be derived from the decode of LA17 through LA23. /MEMCS16 should be

driven with an open collector (300 ohm pull-up) or tri-state driver capable of sinking 20mA.

/MEMR, input/output

These signals instruct the memory devices to drive data onto the data bus. /MEMR is active on all

memory read cycles. /MEMR may be driven by any microprocessor or DMA controller in the system.

When a microprocessor on the I/0 channel wishes to drive /MEMR, it must have the address lines

valid on the bus for one system clock period before driving /MEMR active. These signals are active

low.

/MEMW, input/output

These signals instruct the memory devices to store the data present on the data bus. /MEMW is active

in all memory read cycles. /MEMW may be driven by any microprocessor or DMA controller in the

system. When a microprocessor on the I/O channel wishes to drive /MEMW, it must have the address

lines valid on the bus for one system clock period before driving /MEMW active. Both signals are

active low.

OSC, output

Oscillator (OSC): a high-speed clock with a 70 nanosecond period (14.31818 MHz). This signal is not

synchronous with the system clock. It has a 50% duty cycle. OSC starts 100µs after reset is inactive.

RESETDRV, output

Reset Drive: used to reset or initiate system logic at power-up time or during a low line-voltage outage.

This signal is active high. When the signal is active all adapters should turn off or tri-state all drivers

connected to the I/O channel. This signal is driven by the permanent Master.

/REFRESH, input/output

These signals are used to indicate a refresh cycle and can be driven by a microprocessor on the I/0

channel. These signals are active low.

SA0-SA19, LA17 - LA23 input/output

Address bits 0 through 19 are used to address memory and I/0 devices within the system. These 20

address lines, allow access of up to 1MBytes of memory. SAO through SA19 are gated on the system

bus when BALE is high and are latched on the falling edge of BALE. LA17 to LA23 are not latched and

addresses the full 16MByte range. These signals are generated by the microprocessors or DMA

controllers. They may also be driven by other microprocessor or DMA controllers that reside on the I/0

channel. The SA17-SA23 are always LA17-LA23 address timings for use with the MSCS16 signal.

This is advanced AT96 design. The timing is selectable with jumpers LAxx or SAxx.

/SBHE, input/output

Bus High Enable (system): indicates a transfer of data on the upper byte of the data bus, XD8 through

XD15. Sixteen-bit devices use /SBHE to condition data-bus buffers tied to XD8 through XD15.

SD[0-15], input/output

These signals provide bus bits 0 through 15 for the microprocessor, memory, and I/0 devices. D0 is

the least significant bit and D15 is the most significant bit. All 8bit devices on the I/O channel should

use D0 through D7 for communications to the microprocessor. The 16bit devices will use D0 through

D15. To support 8bit devices, the data on D8 through D15 will be gated to D0 through D7 during 8bit

transfers to these devices; 16bit microprocessor transfers to 8bit devices will be converted to two 8bit

transfers.

DIGITAL-LOGIC AG MSM855/HLV/B/B2 Detailed Manual V1.0A

/SMEMR, input/output

These signals instruct the memory devices to drive data onto the data bus for the first MByte. /SMEMR

is active on all memory read cycles. /SMEMR may be driven by any microprocessor or DMA controller

in the system. When a microprocessor on the I/0 channel wishes to drive /SMEMR, it must have the

address lines valid on the bus for one system clock period before driving /SMEMR active. The signal is

active low.

/SMEMW, input/output

These signals instruct the memory devices to store the data present on the data bus for the first

MByte. /SMEMW is active in all memory read cycles. /SMEMW may be driven by any microprocessor

or DMA controller in the system. When a microprocessor on the I/O channel wishes to drive /SMEMW,

it must have the address lines valid on the bus for one system clock period before driving /SMEMW

active. Both signals are active low.

SYSCLK, output

This is an 8MHz system clock. It is a synchronous microprocessor cycle clock with a cycle time of 167

nanoseconds. The clock has a 66% duty cycle. This signal should only be used for synchronization.

TC, output

Terminal Count: provides a pulse when the terminal count for any DMA channel is reached. The TC

completes a DMA-Transfer. This signal is expected by the onboard floppy disk controller. Do not use

this signal, because it is internally connected to the floppy controller.

/0WS, input

The Zero Wait State (/0WS) signal tells the microprocessor that it can complete the present bus cycle

without inserting any additional wait cycles. In order to run a memory cycle to a 16bit device without

wait cycles, /0WS is derived from an address decode gated with a Read or Write command. In order to

run a memory cycle to an 8bit device with a minimum of one-wait states, /OWS should be driven active

one system clock after the Read or Write command is active, gated with the address decode for the

device. Memory Read and Write commands to an 8bit device are active on the falling edge of the

system clock. /0WS is active low and should be driven with an open collector or tri-state driver

capable of sinking 20mA.

12V, +/- 5%

This signal is used only for the flat panel supply.

GROUND = 0V

This is used for the entire system.

VCC, +5V +/- 0.25V

This signal is used for logic and hard/floppy disk supply.

5. DETAILED SYSTEM DESCRIPTION

This system's configuration is based on the ISA and PCI architecture. Read all information carefully as this is

very new computer technology.

5.1. Power Requirements

This product is an ATX-compatible PC and may only be provided through the power supply connector X8 or

X14/X15 with 5Volts if using the ATX- or ACPI features.

If you do not use the ATX- or ACPI features power may also be provided to the board through the PC104

BUS.

If using the MSMPS104 power supply from DIGITAL-LOGIC, then the ATX- or ACPI features are also

supported on the PC104 BUS.

Attention!

The Pentium-M is a very fast-changing, high-performance processor. The input current is a

direct function of the selected performance. The power supply must be capable of delivering the

maximum possible current (approximately 8Amp). Futhermore the supply must be able to

deliver the inrush current at power-on phase. The inrush current of 15Amp is very high but short

(only a few milliseconds).

We recommend the following power supplies:

1. PC104 PSU: MSMPS104 Part Nr.: 806032 – without UPS function

Part Nr.: 806030 – with UPS function

2. Laboratory PSU: EA-PS 1016-100 (0-16V/10A) http://www.elektroautomatik.de

3. AC/DC Switching PSU: TRACO TOL75-05 (5V/15A/75W) http://www.tracopower.com

5.1.1. Power Supply Cords

Power supply cords must be capable of fulfilling the voltage tolerance over the entire performance ratio. That

means not more than 100mV voltage drop at 8Ampere.

Since board V1.0, we recommend using the X14/X15 connectors to supply the board!

Note…

If you use connector X8: it is important to connect Pin2 and Pin8 of the power supply with +5Volt

and also connect Pin1 and Pin7 with ground. We recommend using a 4-wire cable, not longer

than 20cm, to the power supply.

5.1.3. Minimum Power-Off Time

Attention!

If the power is switched off, there must be a minimum 10 second off period.

All capacitors must be fully discharged before a new power-on is performed.

5.1.4. ATX–Compatible Power Function

Pin Signal Pin Signal

Pin 1 Main switch * Pin 2 GND

Pin 3 Power button **

* J16 default setting: closed by a jumper between Pins 1 and 2. If this jumper is closed until the main supply

comes up, the computer system starts by booting.

If you want to use a push button to start the system:

If this jumper is open until the main supply comes up, the board will not start. You must connect a

push button (main button) to Pin 1-2. After pushing the main button, the board will start. (If you press

the main button for more than 4 seconds, the power will switch off.)

** If you want to use the PWRBTN signal (i.e. in W2k or XP), you must connect another push button to Pins

2-3 of Jumper J16 in order to shut down the Windows OS at the push of the button.

Attention!

After the system is shut down using the power button; to restart, the main button (connected to Pins

1-2) must be used.

The PWRBTN signal is low active and internally pulled to 3.3Volt.

5.1.5. MSM855-HLV-Input (High Level Voltage Input)

Note…

This product is only available with a separate part number (803012). For more information, please

contact your DIGITAL-LOGIC sales partner.

This product is also a MIL VG 96916-5-compatible PC. The board must be supplied through the power

supply connector or X14/X15 with 5-24Volt and 5V through the power pins of the PC104 bus.

The power dissipation of enclosed systems usually used for military mobile applications (24VDC supply) is

very critical depending on the system heat, especially in a harsh environment. For the thermal design power

(TDP) of the complete system, one must also be careful of the loss of DC/DC converters.

Starting with MSM855 Version 1.2, DIGITAL-LOGIC has solved this problem by providing HLV-Input which

allows the possibility of supplying the CPU board directly with 5-24V (approved to MIL VG 96916-5) on the

branch of the high power-consuming supply. For the additional peripheral 5V, a DC/DC converter with only

10W (instead 50-75W) can be used.

We recommend the following DC/DC converter: Eracom RP10S_DEW www.recom-international.de

5.3.4. Floppy Disk Interface

The onboard floppy disk controller and ROM-BIOS support one or two floppy disk drives in any of the

standard PC-DOS and MS-DOS formats shown in the table.

Supported Floppy Formats

Capacity Drive size Tracks Data rate DOS version

1.2MB 5-1/4" 80 500 KHz 3.0 - 6.22

720K 3-1/2" 80 250 KHz 3.2 - 6.22

1.4M 3-1/2" 80 500 KHz 3.3 - 6.22

Floppy Interface Configuration

The desired configuration of floppy drives (number and type) must be properly initialized in the board's

CMOS - configuration memory. This is generally done by using DEL or F2 at boot-up time.

Floppy Interface Connector

The table shows the pin-out and signal definitions of the board's floppy disk interface connector. It is

identical in pin-out to the floppy connector of a standard AT. Note that, as in a standard PC or AT, both

floppy drives are jumpered to the same drive select: as the 'second' drive. The drives are uniquely

selected as a result of a swapping of a group of seven wires (conductors 10-16) that must be in the

cable between the two drives. The seven-wire swap goes between the computer board and drive 'A';

the wires to drive 'B' are unswapped (or swapped a second time). The 26pin high density (1mm pitch

FCC) connector has only one drive and motor select. The onboard jumper defines the drive A: or B:.

Default is always A:.

DIGITAL-LOGIC AG MSM855/HLV/B/B2 Detailed Manual V1.0A

Floppy Disk Interface Technology

Only CMOS drives are supported. This means that the termination resistors are 1 KOhm and 5 1/4“-

drives are not recommended (TTL interface).

5.3.5. Speaker Interface

One of the board's CPU devices provides the logic for a PC compatible speaker port. The speaker logic

signal is buffered by a transistor amplifier, and provides approximately 0.1Watt of audio power to an external

8 Ohm speaker. Connect the speaker between VCC and speaker output to have no quiescient current.

5.3.6.1. USB Interface Protection

Since the MSM855B and the MSM855 V1.3, this protection is implemented in the PCB

For all other versions of the MSM855:

The following is an example of a USB protection circuit (for two USB channels).

Attention!

This circuit must be implemented by the customer or it's possible the USB port or USB devices will

be destroyed (i.e., due to over voltage).

5.3.7. Console Redirection

Use a Null-modem cable to connect COM1 or COM 2 of the MSM855 to the COM1 (COM2) port of the host

PC. In the BIOS setup of the MSM855 you can configure the console redirection:

On the host PC you must start a terminal program (MSDOS or WINDOWS) which is able to show a minimum

of 25 lines.

DIGITAL-LOGIC AG MSM855/HLV/B/B2 Detailed Manual V1.0A

5.4. Controllers

5.4.1. Interrupt Controllers

An 8259A compatible interrupt controller, within the chipset, provides seven prioritized interrupt levels. Of

these, several are normally associated with the board's onboard device interfaces and controllers, and

several are available on the AT expansion bus.

Interrupt Sources Used Onboard

IRQ0 ROM-BIOS clock tick function, from timer 0 Yes

IRQ1 Keyboard controller output buffer full Yes

IRQ2 Used for cascade 2. 8259 Yes

IRQ3 COM2 serial port Yes

IRQ4 COM1 serial port Yes

IRQ5 LPT2 parallel printer (if present) No *

IRQ6 Floppy controller Yes

IRQ7 LPT1 parallel printer Yes

IRQ8 Battery backed clock Yes

IRQ9 Free for user No *

IRQ10 Free for user No *

IRQ11 Free for user No *

IRQ12 PS/2 mouse Yes

IRQ13 Math. coprocessor Yes

IRQ14 Hard disk IDE / SCSI Yes

IRQ15 Free for user No **

* Depends on the LAN configuration.

** IRQ 15 – if the optional CF is not assembled, then free for user.

5.5. Timers and Counters

5.5.1. Programmable Timers

An 8253 compatible timer/counter device is also included in the board's ASIC device. This device is utilized

in precisely the same manner as in a standard AT implementation. Each channel of the 8253 is driven by a

1.190MHz clock, derived from a 14.318MHz oscillator, which can be internally divided in order to provide a

variety of frequencies.

Timer 2 can also be used as a general purpose timer if the speaker function is not required.

Timer Assignment

Timer Function

0 ROM-BIOS clock tick (18.2Hz)

1 DRAM refresh request timing (15µs)

2 Speaker tone generation time base

5.5.2. Watchdog

The watchdog timer detects a system crash and performs a hardware reset. After power up, the watchdog is

always disabled as the BIOS does not send strobes to the watchdog. In case the user wants to take

advantage of the watchdog, the application must produce a strobe at least every 800ms. If no strobe occurs

within the 800ms, the watchdog resets the system. Please refer to the driver/software/BIOS manual

855_BIOS, the chapter on Driver Installation, LINUX SM855 Watchdog Support.

The watchdog function has been available since board Version 1.0.
