090107 OPERATIONS MANUAL EBC-855 3

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 Micro-

FCBGA Package of 479-pins based on 90 nm process technology featuring up to 2 MB

L2 Cache and 400 MHz Front-Side Bus(FSB).

Functional Capability

System Processor

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.

Qualied SODIMMS are available directly from WinSystems. WinSystems cannot

warrant the operation of systems using nonqualied 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 congurable. 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.

Memory

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.

090107 OPERATIONS MANUAL EBC-855 4

Power is applied to the EBC-855 via the connector at J30 (Molex part number 26-60-

7091). The pin denitions 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 species 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.

The EBC-855 BIOS provides conguration 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.

Conguration 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.

Power LED

An LED located at D20 indicates the state of the system as reected in this table.

Power Fail Reset

A precision voltage comparator monitors the +5V status. Upon detection of an out-of-

tolerance 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.

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 congured 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 Conguration

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 conguration 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.

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.
