| OVERVIEW |
The EBC-BX is a feature-rich, single
board computer (SBC) populated with either a low power Celeron® or
low power Pentium® III CPU. The powerful CPU gives engineers a high-performance,
cost-effective, and low-power x86 engine for computational-demanding,
embedded applications. It is a drop-in upgrade to Win-Systems’ EBC-TXPlus
or EBC-LP. It is configured with either a 400 MHz or 700 MHz CPU with
10/100 Ethernet networking capability, advanced video support, four
serial channels, 48 digital I/O lines, and the standard AT peripheral
feature set. The board measures only 5.75 x 8.0-inches and is EBX-compliant.
It supports expansion with PC/104 or PC/104-Plus connectors or with
USB. Its PC software compatibility assures easy program development,
and checkout.
FUNCTIONAL CAPABILITY
Processor - The
EBC-BX is populated with either a 400 MHz Celeron® or
700 MHz Intel® Pentium® III processor.
They are supported from Intel's Embedded Architecture
Division for longer-term availability. Each is
a low power, surface mount BGA2 part designed for
thermally
sensitive and space-constrained applications. Both feature an on-die L1 16KB
instruction and 16KB Write-back data cache operating at the CPU's core frequency.
The 400 MHz Celeron ® includes 128KB of on die L2 cache. The 700 MHz Pentium ® III
includes 256KB of on-die L2 cache operating at the CPUs core frequency. The Pentium ® III's
dual independent bus architecture offers up to three times the bandwidth over
a single bus architecture providing leading edge, low-power processor performance.
System Controller -
The EBC-BX uses the industry standard 440BX chip
set. It consists of an Intel 82443BX North bridge
and South Bridge PCI-ISA-IDE Xcelerator. The 82443BX
provides a host-to-PCI bridge, optimized synchronous
DRAM controller and data path, and an Accelerated
Graphic Port (AGP) interface. It supports the 100
MHz 64-bit Host and SDRAM Bus interface, 32- bit/33MHz
PCI Bus interface, power management, and it integrates
the PCI arbiter. The 82443BX works with the South
Bridge to provide the PCI-to-ISA/IDE bridge functions
along with other features such as a fast IDE interface
(PIO mode 4 and Ultra DMA/66), Plug-n-Play port,
and USB controller functions. It also provides
the core logic that makes the board PC/AT software
compatible including integrated peripheral controllers
(two 82C37 DMAs, 82C54 timer, two 82C59 PICs, RTC,
and CMOS memory) and the ISA bus for PC/104 expansion.
Memory - Up to 256Mbytes
of Synchronous Dynamic RAM (SDRAM) can be installed
on the board by using 168-pin DIMM. A PC-100 compatible
part (non-registered, unbuffered) with gold-plated
fingers is the recommended SDRAM. They are available
from independent memory suppliers such as Crucial
Technology or directly from WinSystems. The board
is shipped from the factory with no memory installed
that permits the user to install and/or upgrade
the memory capacity in the field.
BIOS - An industry-standard,
Award BIOS is onboard to provide configuration
flexibility, performance and AT-compatibility.
It is set with a factory default that can be modified
by the user. The BIOS is located in an EEPROM that
can be modified without removing the storage device
from the board. It will support diskless, keyboard-less,
and videoless operation as well as BIOS shadowing.
Also BIOS extensions can be programmed into another EPROM for remote boot from
the Ethernet, video extensions, etc. This socket is shared with the SSD.
Direct Memory Access (DMA) - Seven DMA channels are supported with Channel
2 dedicated to the floppy disk controller. The LPT is jumper selectable for ECP
operation. The other DMA channels are wired to the PC/104 connector.
Floppy Disk Support -
Up to two 3.5” or 5.25” drives from
360KB through 1.44MB formats are supported by the
CMOS 765B floppy disk controller. It has an enhanced
advanced digital data separator for different data
rates, programmable pre-compensation rates, plus
underflow and overflow protection. Open drain,
push-pull drivers are wired to a standard, single
34-pin connector on 0.100-inch centers. Both drives
can be daisy chained from a single cable.
UDMA/66 EIDE Hard Disk
Interface - The EBC-BX incorporates a PCI
EIDE local bus interface for independent timing
of up to 4 drives. PIO Mode 4 and Bus Master IDE
transfers of up to 28 Mbytes/sec are sup-ported.
Also, it supports Ultra DMA/66 synchronous DMA
mode transfers up to 66 Mbytes/sec. Both the Primary
and Secondary interface channels are wired to a
separate 40-pin header connector on 0.100-inch
centers. Each channel has an LED that blinks during
data transfer to provide visual status information.
Solid State Disk (SSD) Support - A JEDEC standard 32- pin, machine-tooled socket
is provided to accept an M-Systems’ DiskOnChip® (DOC). The DOC offers
from 8 meg to 1 gigabyte storage capacities in a single device. It includes an
internal flash file system that provides
hard disk read/write compatibility, automatic bad block management, and wear-leveling.
A designer can use an onboard semiconductor device for applications where the
environment is too harsh for mechanical hard disks or floppy disk drives while
offering significant speed
advantages.
Ethernet Controller - An Intel 82551ER is the 32-bit
PCI Ethernet controller chip used for high-speed data transfer. It has auto negotiation
capability for speed, duplex, and flow control. It supports IEEE 802.3 10-BaseT
and 100BaseT in either full- or half-duplex mode at both 10
and 100 Mbps. In full-duplex mode, it adheres to the IEEE 802.x Flow Control
Specification.
Two large 3Kbyte transmit and receive FIFOs help prevent data underruns and overruns.
It has fast back-to- back transmission support with minimum interframe spacing.
It also has improved dynamic transmit chaining with multiple priorities transmit
queues. There are three LEDs on the board that provide status information. The
red LED indicates 100BaseT, the yellow indicates Link, and the green is the Rx/Tx
packet data.
The 82551ER chip is very popular both in the commercial and industrial PC-compatible
market. This means that most PC-compatible drivers, utilities and 10/100 Ethernet
supported operating systems will work directly with the EBC-BX. The configuration
information describing the device’s architecture, address, interrupt, etc.
is stored in a serial EEPROM.
Networking - The EBC-BX
supports remote booting with an onboard EPROM socket
for use as a diskless network computer. Optionally,
a 64KB Flash can be populated for boot block support.
The Intel 82551ER is supported by numerous network OSs
and kernels.
Video Controller - An
Asiliant 69000 high-performance PCI flat panel/CRT
controller provides a sophisticated graphics accelerator
video engine. It has a 66 MHz, 1x AGP interface to
the CPU to improve its performance. It supports a wide
variety of monochrome and color active and passive
LCD panel displays. The 69000 supports up to 16.7M
colors on 24-bit, active matrix LCDs. Programmable
horizontal and vertical stretching capabilities are
available for text and graphics modes for optimal display
on 800x600, 1024x768 and 1280x1024 panels. It also
has support for 16:9 aspect ratio panels.
Two megabytes of video memory is on the chip which is sufficient to support the
screen resolutions and maximum number of colors displayed required by most applications.
As an option, the EBC-BX can also be supplied with an Asiliant 69030 controller.
This controller has 4MB of internal video RAM rather than the standard 2MB that
is integrated into the 69000 controller. More memory permits more color depth
at higher resolutions. Contact a factory application engineer for more details
and pricing.

CRT Video Interface -
A triple 8-bit integrated RAM-DAC provides CRT support.
The CRT video output signals are wired to a 14-pin
dual-in-line connector at the edge of the board. An
optional CBL-234-1 interface cable adapts it to a standard
female 15-pin “D-Sub” type connector commonly
used for VGA. Simultaneous operation of the CRT and
LCD is supported.
Flat Panel Display Support -
The EBC-BX supports most flat panel display technologies
including plasma, electro luminescent (EL), active
matrix TFT/MIM LCD, passive STN and single panel, Single
Drive (SS). It will support mono and color displays.
The board properly sequences the power for logic voltage
and the backlight inverter to provide intelligent and
safe power sequencing to the panel.
FP-100 Interface - Since
there is not an electrical or mechanical interface
standard for flat panels, WinSystems has developed
a flat panel interface system configuration to work
with the different interface signals, timing requirements,
and connectors that vary between panel technologies
and suppliers. The FP-100 video bus supports panels
up to 24-bits per pixel. It has power, timing and control
signals for various panel types. The logic levels are
3.3 volts but are 5.0V tolerant. Also, 4 lines are
assigned to allow the EBC-BX to read an ID jumper setting
on the personality module or cable to auto configure
the BIOS for the correct panel type.
Two, 50-pin, 2-mm connectors are used for the flat panel interface. Most connections
can be made directly with a modified cable, others will require a flat panel
adapter module. Contact a WinSystems factory application engineer with your specific
panel requirements.
Software drivers are available with high-resolution drivers for various software
packages including Linux, DOS, Windows XP/CE/NT, and certain RTOS applications.
A BIOS extension in the onboard EPROM provides PC video compatibility for the
various modes of operation for the different panels. Video BIOS modifications
can be made for custom panel types.
USB - The Universal
Serial Bus offers users simple connectivity with peripheral
devices. This board has a USB port that supports transfers
at either 1.5 or 12 Mbits/sec. The USB is wired to
a 4-pin connector. An optional CBL-249-1 is the interface
cable adapter to a standard female USB connector.
Serial Communications -
Four independent, full-duplex, RS-232 serial asynchronous
channels are onboard. Both the send and receive registers
of each channel has a 16-byte FIFO. This device is
a dual 16C550 compatible UART that offers software
compatibility with PC-type driver programs.
Independent control of transmit, receive, line status and data set interrupts
are on all channels. Each channel is setup to provide internal diagnostics as
loopback and echo mode on the data stream. An independent on-chip software programmable
baud rate generator is selectable from 50 through 115.2 kbits/sec. Individual
modem handshake control signals are supported for all channels.
RS-232 interface levels are supported on all channels. The RS-232 drivers have
an on-chip charge pump to generate the plus and minus voltages so that the EBC-BX
only requires +5 volts to operate.
Also RS-422, RS-485 or J1708 electrical levels can be supported on COM1 and COM2
by removing the RS-232 transceivers and installing the optional CK-75176 chip
kit.
All serial channels are configured as Data Terminal Equipment (DTE). COM1 and
COM2 are wired to a 50- pin connector at the edge of the board. WinSystems offers
the optional CBL-247-1, which adapts each serial channel to 9-pin male “D” connectors.
COM3 and COM4 are wired to a 20-pin connector on the board. WinSystems offers
the optional CBL-173-1, which adapts each serial channel to 9-pin male “D” connectors.
48-line Parallel I/O - The EBC-BX contains a highly versatile WS16C48,
48-line digital I/O controller. Each I/O line is individually programmable for
input, output, or output with read-back operation. Each out-put channel is latched
and has an open collector driver (with a pull-up resistor) capable of sinking
12mA of current.
The major feature of this controller is its ability to monitor 24 of the lines
for both rising and falling digital edge transitions, latch them and then interrupt
the host processor notifying that a change-of-input status has occurred. Transition
polarity is programmable and enabled on a bit-by-bit basis. Each line’s
transition is latched by the event so that even short duration pulses will be
recognized. An interrupt ID register is maintained for each line for writing
more efficient Interrupt Service Routines. This is an efficient way of signaling
the CPU of real-time events without the burden of polling the digital I/O points.
The WS16C48 has its I/O lines connected to two, 50-pin occurred. Transition polarity
is programmable and enabled on a bit-by-bit basis. Each line’s transition
is latched by the event so that even short duration pulses will be recognized.
An interrupt ID register is maintained
for each line for writing more efficient Interrupt Service Routines. This is
an efficient way of signaling the CPU of real-time events without the burden
of polling the digital I/O points.
The WS16C48 has its I/O lines connected to two, 50-pin connectors. Twenty-four
data lines are alternated with 24 ground lines for reduced noise and crosstalk.
Also +5 volts and ground are included in the cable. The pinout is compatible
with the industry standard 4 to 24 position I/O module mounting racks (Opto-22,
etc.) for use with high-level AC and DC opto-isolated solid state relays. An
optional CBL-115-4, 50-pin conductor ribbon cable connects the EBC-BX to one
I/O rack.
Printer Port - The EBC-BX
has a parallel port that may be operated in standard
and bidirectional as well as Extended Capabilities
Port (ECP - IEEE-1284) and Enhanced Parallel Port (EPP)
modes. The controller chip is designed to provide enhanced
ESD and latch-up protection of up to 4KV/300mA.
The printer port can also be used as two additional general-purpose I/O ports
if a printer is not required. The first port is configured as 8 input or output
only lines. The other port is configured as 5 input and 3 output lines.
Keyboard/Mouse Controller -
An 80C42 equivalent controller supports a PC/AT-compatible
keyboard. The optional CBL-247-1 adapter cable provides
the mate to a PS/2 type keyboard plug.
A standard mouse controller is on board. Its input is accessible through a 5-pin
connector. WinSystems’ optional CBL-225-1 adapter cable interfaces the
mouse cable connector to this board.
Multi-I/O Connector Cable Adapter -
WinSystems offers the optional CBL-247-1, Multi-I/O
cable adapter for the COM1, COM2, LPT1 and keyboard.
These four ports are combined into one 50-pin header
at the edge of the board. The CBL-247-1 is a 1-foot
adapter cable that offers a more convenient termination.
COM1 and COM2 are 9-pin male “D” connectors
with strain relief. LPT1 is a 25-pin “D” female
socket with strain relief. The keyboard is a standard
6-pin PS/2 connector socket.
Interrupts - Two 82C59A compatible interrupt controllers accept inputs
from the onboard peripherals and the PC/104 Bus for a total of twelve selectable
interrupt sources. Also four PCI interrupt sources are supported on the PC/104-Plus
Bus which are PnP compliant.
Status LED - A green
status LED is also available to monitor system activity.
Under a user’s program control, it can indicate
error conditions or blink different patterns to provide
a visual indication of system status.
Real Time Clock - An
MC146818A-compatible clock supports a number of features
including periodic and alarm interrupt capabilities.
In addition to the time and date keeping functions,
the system configuration is kept in CMOS RAM contained
within the clock section.
Watchdog Timer - A software/hardware
enabled, retriggerable watchdog timer is provided.
This timer must be updated at least once every 1.5
or 15 seconds (jumper selectable) otherwise a failure
is assumed and the board will be reset. This circuit
is important for use in remote and unattended applications.
Timers - Three, independent
82C54 compatible 16-bit timers are supported. Channel
0 is wired to interrupt Channel 0, Channel 1 generates
the DRAM refresh using DMA Channel 0, and the speaker
port uses Channel 2.
Speaker - An onboard
speaker is available for sound generation. A beep code
is generated that corresponds to any BIOS error codes
(if required) during the power up or reset sequence.
Power - Power is supplied
via a 9-pin connector. For most applications, the board
only requires +5 volts. However, some flat panels may
require +12 volts for the backlight inverter. Additional
the ±12V is wired to the PC/104 connector.
Reset - A precision
comparator monitors the status of 3 critical board
voltages. 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.
Battery - A 350 mAH
battery supplies the EBC-BX board with standby power
for the real time clock and CMOS setup RAM. A power
supervisory circuit senses the off- board voltage and
automatically switches to internal power when it drops
below normal.
Standalone Operation -
The board can be used as a complete, standalone embedded
controller mounted on a flat surface using a set of
standoffs. The EBC-BX measures 5.75 x 8.0 inches (146mm
x 203mm).
PC/104 Expansion -
The EBC-BX provides a common computer core from which
engineers can add off-the-shelf or user-designed, application-specific
PC/104 modules. PC/104 modules are self-stacking and
plug together in a “piggy back” configuration
to serve as a mezzanine expansion bus. PC/104 modules
are very compact, measuring only 3.6 x 3.8 inches,
and are offered by WinSystems and a number of third
party companies worldwide. Module functions include
specialty serial I/O, digital I/O, networking, GPS,
modem, audio, SCSI, etc.
The EBC-BX has both a 16-bit PC/104 and a 32-bit PC/104-Plus interface and connector.
PC/104 is the ISA bus and PC/104-Plus is the PCI bus for I/O functions requiring
higher data transfer speeds.
SOFTWARE SUPPORT
Software - The EBC-BX
is designed to run both 16-bit and 32-bit x86 instruction
set software. It is compatible with Microsoft’s
Windows operating systems, such as Windows CE, Windows
XP, Windows NT® and Windows NTE as well as the
applications that run on them. It also supports Linux
and other PC-compatible x86 operating systems such
as QNX, VxWorks, and OS9000. It will also run other
real-time executives that require a “PC-AT” hardware
environment.
Software Developers Kit - WinSystems offers the SDK3- EBC-307-D software
developers kit to provide the necessary hardware, software and cables to begin
program development with the EBC-BX board. One of the configurations consists
of DOS 7.x, CBL-247-1 Multi-I/O cable, CD-ROM drive, a 2GB or larger hard disk
plus controller cable, a 1.44 MB high density 3.5 inch floppy disk plus controller
cable and triple output power supply housed in an enclosure. Also a PCM-POST
module is included for debugging support.
The power supply is an 80-Watt universal switcher that will accept input voltages
from 85 VAC to 264 VAC. Output voltages are +5 volts at 12A, +12 volts at 3A,
and -12 volts at 1A. The power supply, floppy disk and hard disk are mounted
in a black aluminum enclosure. The packaging permits easy access to the board,
PC/104 modules and peripherals during program development.
