System Processor
The EBC-855 is based upon the Intel Pentium M or Zero Cache Dothan (ZCD) CPU
which supports two speeds: Pentium M 1.8 GHz and ZCD 1.0 GHz. It uses a MicroFCBGA Package of 479-pins based on 90 nm process technology featuring up to 2 MB
L2 Cache and 400 MHz Front-Side Bus(FSB).
System Controllers
The EBC-855 uses Intel 855GME for the North Bridge to interface to the CPU, DDR SDRAM
memory and the graphics interface. The 732-pin Micro-FCBGA packages support: a 400
MHz Front-Side Bus (FSB), host bus dynamic bus inversion (DBI), 64-bit host data bus
and 32-bit addressing. The memory system supports 200/266/333 MHz DDR SDRAM
device (up to 1 GB). There is also a graphics controller with LVDS and CRT support.
The Intel ICH4 South Bridge provides many I/O features. It contains two IDE ports
– Primary (HDD) and Secondary (CF) with ATA100, audio codec AC97, four USB ports
(2.0), SM Bus, LAN link to Intel Ethernet controller, general purpose I/O ports, low pin
count bus interface, PCI Bus interface, Real-Time Clock (RTC), watchdog timer and power
management.
Memory
The EBC-855 can support a maximum of 1 GB of RAM with the 200-pin SODIMM socket
located on the back of the board at DIMM1.
Qualied SODIMMS are available directly from WinSystems. WinSystems cannot
warrant the operation of systems using nonqualied SODIMM modules.
The RAM can be user supplied, but must meet the following criteria:
200-Pin SODIMM PC2700 DDR SDRAM with gold ngers (up to 1 GB)
Installation is accomplished by inserting the module into the connector at
approximately a 30 degree angle. Press rmly to fully seat the module into the
connector and then press the module downward to snap it into the retaining clamps.
Removal is accomplished by gently pulling outward on the retaining clamps until the
module springs up to the appropriate removal angle.
DMA
DMA is supported. Channel 2 is dedicated to the oppy disk controller. The LPT is
plug-and-play congurable. The other 8-bit DMA channels are wired to the PC/104
connector. 16-bit channels are not supported.
Interrupt Routing
All interrupts are routed to their respective PC/104 bus pins. The Digital I/O is the
only interrupt routing that is jumper selectable at J13. For further details, refer to
the Digital I/O Section later in this manual.

Power and Reset Interface
Visual
Index
Power is applied to the EBC-855 via the connector at J30 (Molex part number 26-60-
7091). The pin denitions for J30 are given below. An optional push-button-reset
(normally OPEN) may also be routed into J30, pin 9 if desired. Momentary closure to
ground forces a hardware reset.

Power Supply Selection
The EBC-855 supports either AT or ATX type power supplies. J21 species the style of supply
connected to the single board computer (SBC). An AT power supply is a simple on/off supply with
no interaction with the single board computer. Most embedded systems use this type of power
supply and it is the default setting.
ATX type power supplies function with a “soft” on/off power button and a +5 VSB (standby). If
an ATX compatible power supply is connected, J21 should be set accordingly and a power button
(momentary contact) connected between pin 2 (power button) and pin 1 (ground) of J29. The
+5 VSB signal on J29 provides the standby voltage to the EBC-855 but does not power any other
features of the board. When the power button is pressed, the EBC-855 pulls PSON (Power Supply
On) low and the power supply turns on all voltages to the single board computer. When the power
button is pressed again, the BIOS signals the event so ACPI-compliant operating systems can be
shutdown before the power is turned off. Since this is software driven, it is possible that a software
lockup could prevent the power button from functioning properly. For the BIOS to report the ATX
supply to ACPI-compatible operating systems, J21 must be setup correctly.
Note: True ATX power supplies are not applicable for embedded systems. They are typically
300W supplies and may not regulate properly with low power embedded systems such as the
EBC-855.

Power Fail Reset
A precision voltage comparator monitors the +5V status. Upon detection of an out-oftolerance condition, the board is reset. This action is critically important in order to detect
brownout or power fail conditions. The reset circuit also ensures that the power is nominal
before executing a power-on reset. This circuit also inhibits the processor’s memory
write line, preventing invalid data from being written to nonvolatile memory during power
uctuations.
BIOS
The EBC-855 BIOS provides conguration exibility, performance and AT-compatibility.
It includes enhancements required for embedded applications like the ability to
boot without a keyboard or video monitor present, and save settings to EEPROM.
Conguration options and instructions are discussed in more detail in the BIOS
Supplemental later in this manual.
Saving BIOS Setup
The EBC-855 provides two methods for saving BIOS setup data:
Standard battery backed CMOS RAM and Nonvolatile EEPROM.
The battery is enabled/disabled using connector J31. For further details, refer to the Battery
Backup Section later in this manual.
The EEPROM write/read functionality is enabled/disabled at J16, pins 3 and 4.

Real-Time Clock/Calendar
A real-time clock (RTC) is used as the AT-compatible clock/calendar. It supports a number of
features, including periodic and alarm interrupt capabilities. In addition to the time and date
keeping functions, the system conguration is kept in CMOS RAM contained within the clock
section.
Battery Backup
A connector is available at J31 to provide battery backup to the real-time clock
and CMOS. The battery input voltage range is 3.0V to 3.6V, ±5%. An extended
temperature lithium battery capable of backing up the EBC-855 is available from
WinSystems, part number BAT-LTC-E-36-27-1 (or BAT-LTC-E-36-16-1 if applicable).

Serial Interface
Visual
Index
The EBC-855 provides four, 16C550 compatible, RS-232 serial ports. COM1 and COM2 are
terminated at J28, the 50-pin Multi-I/O connector, and can be congured for RS-232,
RS-485 or RS-422. An adapter cable, part number CBL-247-1, is available from WinSystems
to adapt to the conventional I/O connectors. COM3 and COM4 are RS-232 only and are
terminated at J24. WinSystems offers an adapter cable, CBL-173-1, which adapts J24 to
two standard DB9M connectors. For additional information on cable connection, refer to the
cable drawings.
COM1 and COM2 Conguration
COM1 and COM2 addresses and interrupts are set using the BIOS CMOS setup. Both COM1 and
COM2 can be individually jumpered for any one of the following operating modes:
1. RS-232 Mode
2. RS-422 Mode with RTS transmitter enable
3. RS-422 Mode with auto transmitter enable
4. RS-485 Mode with RTS transmitter enable
5. RS-485 Mode with RTS transmitter enable and echo back
6. RS-485 Mode with auto transmitter enable
7. RS-485 Mode with auto transmitter enable and echo back
Modes 2, 4 and 5 require the RTS bit (MCR Bit 1) be set in order to Transmit.
Mode 4 requires that RTS (MCR Bit 1) be de-asserted in order to receive.
Each of the RS-422/RS-485 modes allow for jumper selection of transmit and/or receive termination
resistor(s). There is an 11-pin conguration jumper for COM1 and COM2 that allows the user
to select the operating mode and its optional features and termination. The jumper numbers
and corresponding port numbers are shown on the following pages. There are three choices for
termination when RS-422 or RS-485 modes are used.
TX(100) : Places a 100Ω resistor across the TX+/TX- pair
RX(100) : Places a 100Ω resistor across the RX+/RX- pair
TX/RX(300) : Places a 100Ω Resistor from +5V to TX/RX+, a 100Ω resistor
from TX/RX- to ground and a 100Ω resistor between TX/RX+ and
TX/RX-.

Flat Panel Connections
WinSystems provides at panel support with a series of cables and support hardware. Contact
your WinSystems’ Applications Engineer for the most current list of supported panels. This
manual does not attempt to provide any information about how to connect to specic
LCDs. Attempted connection to any at panel not directly supported by WinSystems is at the
user’s risk. Extreme care should be exercised to avoid damaging or destroying the panel. For
additional information contact your WinSystems’ Applications Engineer.
HAZARD WARNING: LCD panels can require a high voltage for the
panel backlight. This high-frequency voltage can exceed 1000 volts
and can present a shock hazard. Care should be taken when wiring
and handling the inverter output. To avoid the danger of shock and
to avoid the panel, make all connection changes with the power
removed.

Watchdog Timer
The EBC-855 features a watchdog timer, which can be used to guard against software lockups.
The watchdog can be congured from the CMOS setup utility or directly from software. (See
its description in BIOS Supplemental.) The selection in the CMOS setting serves as the default
timeout value as the processor boots. The BIOS option is for enabling the watchdog only during
boot.
The watchdog powers up disabled (566h = 00h) unless it is enabled in the CMOS setting.
When the watchdog is disabled at boot, it can be re-enabled through application software.
The watchdog is enabled by writing a timeout value other than zero into the I/O address 566h.
Writing 00h to the I/O address 566h will disable the watchdog.
The watchdog timer is serviced by writing the timeout to I/O port 566H. If the watchdog has
not been serviced within the allotted time, the circuit resets the CPU.
The timeout value written into port 566h is in seconds if port 565 bit 7 equals 1. If port 565 bit
7 equals 0, the timeout value written into port 566h is in minutes.
Note: It is recommended that the long timeout (300 seconds) be used with the watchdog enabled
when trying to boot any operating system.

BIOS Supplemental
General Information
The EBC-855 comes equipped with a Phoenix® BIOS to assure full compatibility with PC operating
systems and software. The basic system conguration is stored in battery backed CMOS RAM within
the clock/calendar. As an alternative to operate without a battery, the conguration may be stored
in an EEPROM. Access to this setup information is via the Setup Utility in the Phoenix® BIOS.
Entering Setup
To enter setup, power up the computer and press F2 when either the splash screen is displayed
(when enabled) or when the Press F2 for Setup message is displayed. Alternately, under certain
error conditions a message similar to: Press F1 to Continue or F2 for Setup may be displayed.
Press the desired key for the appropriate action. The BIOS will display the message: Entering
Setup and will continue with the remainder of the POST routines. It may take a number of seconds
before the main setup menu screen is displayed.
Navigation of the Menus
Use the Up and Down arrow keys to move among the selections and press ENTER when a selection
is highlighted to enter a sub-menu or to see a list of choices. Use the - and + keys to change
values for particular items. Pressing the letter corresponding to each menu option is a shortcut
that opens the next dialogue box with one key press.
The default conguration of each menu screen is shown on the following pages and is followed
by a brief description of each option where applicable. Values shown in bold typeface are factory
defaults while descriptions and options are italicized.
BIOS Conguration Location
The EBC-855 BIOS conguration table (CMOS image) is located in CMOS RAM. The values of this
table can be populated from either three (3) locations:
(1) CMOS RAM (when battery backed) and is user congurable
(2) EEPROM (nonvolatile) and is user congurable
(3) FLASH PROM – contains the BIOS and factory default conguration
Saving the BIOS Conguration
The Real-Time Clock and the CMOS RAM can be powered by an optional battery connected to J31.
If no battery is present, CMOS defaults are normally loaded each time the board is powered on.
The EEPROM feature allows the user to save BIOS conguration options without requiring a
battery. When a jumper is installed between J16 (3-4), the user can save the CMOS settings to
the EEPROM.
At system boot, the BIOS rst performs a checksum validation on the contents of the CMOS RAM.
Upon successful validation, the BIOS continues the process using values stored in CMOS RAM. If
a checksum error occurs, the BIOS attempts to load the conguration table from the EEPROM.
Checksum errors usually occur due to a low or disabled battery.
After a checksum validation, the BIOS conguration is loaded from the EEPROM and the boot
process continues. If the EEPROM is disabled or another checksum error occurs, the BIOS loads the
minimum BIOS conguration settings from the FLASH PROM and the boot process continues.
For applications where the battery is enabled, it is recommended to save the BIOS conguration
to both the CMOS RAM and the EEPROM. If a battery fails at a later point, the BIOS defaults will
be loaded from the EEPROM so operation can continue without user interaction. The disadvantage
to saving the CMOS setting to the battery backed CMOS RAM is that all of the custom settings are
lost when the battery fails or if the CMOS gets corrupted (CMOS checksum error).
090107 OPERATIONS MANUAL EBC-855 22
Resetting Factory Defaults
The EBC-855 can normally be returned to the factory default BIOS conguration by selecting Load
Setup Defaults in the Phoenix® BIOS Setup Utility.
When using battery backup, the CMOS setup data can be reset to defaults by momentarily adding
a jumper at J16 (1-2) with the system power off. Make sure to disable the EEPROM backup of
CMOS data when clearing CMOS to ensure that data within the EEPROM does not load instead of
factory CMOS setup defaults. (See below.)
To Disable EEPROM CMOS
To disable EEPROM CMOS backup data from loading at power-on, remove the jumper at J16 (3-4)
prior to boot up. After booting up, the J16 (3-4) jumper can be replaced and new CMOS setup
information saved to EEPROM through CMOS setup.
It is advisable to remove the jumper from J16 (3-4) when updating the BIOS. Follow the steps below
to ensure that data from a previous BIOS version in the EEPROM does not affect operation.
1) Reboot with jumper at J16 (3-4) removed after any BIOS update.
2) Enter Phoenix® BIOS Setup Utility.
3) Install a jumper at J16 (3-4).
4) Save settings to EEPROM from CMOS setup

Updating the BIOS FLASH PROM
The most recent EBC-855 BIOS is available on the WinSystems website, but it is highly recommended
that an Applications Engineer be consulted prior to any BIOS FLASH PROM update. If a BIOS
update is required, please follow the steps Resetting Factory Defaults above to ensure that the
data from a previous version is cleared from EEPROM.

Software Summary
WS16C48 Register Denitions – The EBC-855 uses the WinSystems exclusive ASIC device,
the WS16C48. This device provides 48 lines of digital I/O. There are 17 unique registers within
the WS16C48. The following table summarized the registers and the text that follows provides
details on each of the internal registers.

Register Details
Port 0 through 5 I/O – Each I/O bit in each of the six ports can be individually programmed
for input or output. Writing a 0 to a bit position causes the corresponding output pin to go to a
high-impedance state (pulled high by external 10 KΩ resistors). This allows it to be used as an
input. When used in the input mode, a read reects the inverted state of the I/O pin, such that
a high on the pin will read as a 0 in the register. Writing a 1 to a bit position causes that output
pin to sink current (up to 12 mA), effectively pulling it low.
INT_PENDING – This read-only register reects the combined state of the INT_ID0 through
INT_ID2 registers. When any of the lower three bits are set, it indicates that an interrupt is
pending on the I/O port corresponding to the bit position(s) that are set. Reading this register
allows an Interrupt Service Routine to quickly determine if any interrupts are pending and which
I/O port has a pending interrupt.
PAGE/LOCK – This register serves two purposes. The upper two bits select the register page in
use as shown here:
D7 D6 Page
0 0 Page 0
0 1 Page 1
1 0 Page 2
1 1 Page 3
Bits 5-0 allow for locking the I/O ports. A 1 written to the I/O port position will prohibit further
writes to the corresponding I/O port.
090107 OPERATIONS MANUAL EBC-855 64
POL0 - POL2 – These registers are accessible when Page 1 is selected. They allow interrupt
polarity selection on a port–by–port and bit-by-bit basis. Writing a 1 to a bit position selects the
rising edge detection interrupts while writing a 0 to a bit position selects falling edge detection
interrupts.
ENAB0 - ENAB2 – These registers are accessible when Page 2 is selected. They allow for port-byport and bit-by-bit enabling of the edge detection interrupts. When set to a 1 the edge detection
interrupt is enabled for the corresponding port and bit. When cleared to 0, the bit’s edge detection
interrupt is disabled. Note that this register can be used to individually clear a pending interrupt
by disabling and re-enabling the pending interrupt.
INT_ID0 – INT_ID2 – These registers are accessible when Page 3 is selected. They are used to
identify currently pending edge interrupts. A bit when read as a 1 indicates that an edge of the
polarity programmed into the corresponding polarity register has been recognized. Note that a
write to this register (value ignored) clears ALL of the pending interrupts in this register.
