| OVERVIEW |
The EBC-LP
is a feature-rich, Pentium-based single board
computer (SBC) for industrial applications. The
powerful
CPU gives engineers a high-performance, cost-effective,
and low-power x86 engine for computational-demanding,
embedded applications.
It is configured with either a 166 MHz or 266 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 and PC/104-Plus
connectors or with USB. The 166 MHz board does
not
require a fan and will operate over an extended
temperature
range that makes it ideal for rugged applications
requiring an embedded PC. Its PC software compatibility
assures easy program development, and
checkout.
FUNCTIONAL CAPABILITY
Processor - The EBC-LP is populated with
the Intel® low
power embedded 166 MHz or 266 MHz Pentium® processor
with MMX® technology. It provides additional
performance and low power for embedded applications.
Its superscalar architecture can execute two
instructions per clock cycle, and its enhanced
branch
prediction and separate 16KB code and data caches
also
increases performance.
System Controller - An Intel 430TX PCIset is the
system
controller for this SBC. It consists of the 82439TX
System Controller (MTXC) and the 82371AB PCI-ISA-IDE
Xcelerator. The MTXC provides an integrated solution
for the system controller and data path components
for
a Pentium/K6 processor system. It has the 64-bit
Host
and SDRAM bus interface, 32-bit/33MHz PCI Bus inter-face,
L2 cache controller, and it integrates the PCI
arbiter.
The MTXC also implements extensive power management
features. The MTXC works with the PIIX4E 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/33), Plug-n-Play port (PnP), 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 256 Mbytes of Synchronous
Dynamic RAM (SDRAM) can be installed on the board
by using a
168-pin DIMM. A PC-66 or PC-100 compatible part
(non-registered, unbuffered) with gold-plated fingers
is
the recommended SDRAM. They are available from
independent memory suppliers 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.
The EBC-LP is shipped with 512KB of onboard
pipelined burst external cache to further improve
the
performance of the system. A 64K x 64 SRAM is the
cache device that is direct mapped in Write Back
mode.
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, keyboardless,
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/33 EIDE Hard Disk Interface - The
EBC-LP 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 14 Mbytes/sec are
sup-ported.
Also, it supports Ultra DMA/33 synchronous
DMA mode transfers up to 33 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
to 1GB 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-LP. The configuration information
describing the device's architecture, address, interrupt,
etc. is stored in a serial EEPROM.
Networking - The EBC-LP 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 supports a wide
variety of monochrome and color active and passive
LCD panel displays. The 69000 can support up to
16.7M colors on 24-bit, active matrix LCDs.
Programmable horizontal and vertical stretching capabilities
are also 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.
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-LP
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-LP 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 98/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-LP
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-LP 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
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-LP to one I/O rack.
Printer Port - The EBC-LP 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-LP 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-LP measures
5.75 x 8.0 inches (146mm x 203mm).
PC/104 Expansion - The EBC-LP 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-LP 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-LP is designed to run both 16-bit
and 32-bit x86 instruction set software. It is compatible
with Microsoft® Windows operating systems, such as
WindowsCE, Windows98, WindowsNT®
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-
EBX-306-D software developers kit to provide the necessary
hardware, software and cables to begin program
development with the EBC-LP board. One of the con-figurations
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
