| OVERVIEW |
The MCM-6117
is a 386SX-compatible STD Bus SBC that
provides a wide variety of I/O functions on a single
card. The I/O complement includes 4 serial COM
channels,
48 digital I/O lines, as well as the standard AT-peripherals
of keyboard controller, real time clock, line
printer port, plus IDE and floppy disk controllers.
It can replace both 386SX and V53-based STD Bus
SBCs
from WinSystems (MCM-SBC53) plus Ziatech's V53/V40
(ZT8901, ZT8801, & ZT8802) and Pro-Log's 7871.
The MCM prefix on the MCM-6117 card designates
a standard STD Bus board. The LPM prefix designates
a
CMOS STD Bus board. A MCM/LPM prefix indicates
the
card has the same features and functionality and
is available
in both CMOS and regular NMOS/TTL logic. The
differences between these two are the power requirements
and operational temperature range.
FUNCTIONAL CAPABILITY
Processor - The 386SX-compatible processor
and core
logic chipset are integrated into a highly efficient
single
chip device that includes the DRAM controller,
bus
interface and integrated peripheral controllers.
The AT-class
peripherals include two 8237 DMAs, 8254 timer,
two 82C59 interrupt controllers, real time clock
and
CMOS memory. The processor operates at system clock
speed of 33 MHz.
Memory - Up to 8 Mbytes of surface mounted DRAM
is populated on the board. These parts are soldered
directly to the board to improve reliability for
applications
subject to shock and vibration. The factory supplied
memory sizes are 2MB, 4MB or 8MB.
An industry-standard, Award BIOS is on the board
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.
16-Bit IDE Hard Disk Interface - A 40-pin
header connector
handles all command, data, and status I/O lines
to an industry standard interface. A status LED
provides
a visual status during data transfers.
Floppy Disk Support - Up to two 3.5" or 5.25" drives
from 360KB through 1.44MB formats are supported
by
the floppy disk controller. Both drives can be
daisy
chained on a single cable wired to a 34-pin connector
on 0.100-inch centers.
Solid State Disk (SSD) - A JEDEC standard,
32-pin machine-tooled socket is supported but not
populated. It can hold an M-Systems DiskOnChip®, Atmel PEROM
or additional BIOS extensions. The DiskOnChip®
can
store up to 1Gigabyte of data. It also includes
TrueFFS
® that is an embedded flash file system. This
file
system provides hard disk read/write compatibility,
automatic bad lock 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.
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.
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 such as loop-back
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 four
channels.
The RS-232 drivers have an on-chip charge pump
to generate the plus and minus voltages so that
the
MCM/LPM-6117 only requires +5 volts to operate.
Also RS-422, RS-485 or J1708 electrical levels
can be supported
on COM3 and COM4 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 MCM/LPM-6117
contains a
highly versatile WS16C48, 48-line digital I/O controller
that is TTL compatible. Each I/O line is individually
programmable for input, output, or output with read-back
operation. Each output 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 MCM/LPM-6117 to one I/O rack.
Line Printer Port - The MCM/LPM-6117 has a parallel
port that may be operated in standard and bi-directional
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 Controller - An 80C42 equivalent controller
supports a PC/AT-compatible keyboard. It is wired to
the 50-pin multi-I/O connector. The CBL-247-1 adapter
cable provides the mate to a PS-2 type keyboard.
Interrupt Sources - Two 82C59A compatible
interrupt controllers accept inputs from the onboard
peripherals, the INTRQ* lines from the STD Bus, and
the PC/104 Bus interrupt sources. The MCM/LPM-6117
contains a 10- pin interrupt connector at the top of
the card (OTT). This provides backward compatibility
for WinSystems' MCM/LPM-286, MCM/LPM-386SX, MCM/LPM-486SLC,
and MCM/LPM-DX5 boards. It also provides five additional
interrupt sources to the board in addition to those
provided through the STD Bus backplane.
STD Bus I/O - The MCM/LPM-6117 conforms
to the PC-AT I/O map and STD Bus standard 10-bit addressing.
It will support older STD Bus I/O boards that decode
only
8 address bits, 8 bits with IOEXP*, and the newer 10-bit
cards.
Status LED - A red 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,
re-triggerable watchdog timer is provided. This timer
must be updated at least once every 1.5 seconds 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 piezo transducer
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. Also, a 3-pin header is
provided
for the speaker output. An optional ADP-SPEAKER
is available from WinSystems that includes an amplifier
and speaker for remote mounting.
Reset - A precision voltage monitors the
+5 volt 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.
Battery - A 350-mAH battery supplies MCM/LPM-6117
the 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.
Expansion Options - The MCM/LPM-6117 provides
a common computer core from which engineers can add
user designed or off-the-shelf boards to match their
exact configuration. The board can support 2 different
modes: STD Bus or PC/104 bus.
STD Bus - This board supports both 8-
and 16-bit transfers
on the STD Bus. Logic automatically detects the
memory and I/O transfer data path widths and aligns
the
transfers accordingly.
As the approved IEEE-961 standard, the STD Bus is popular
worldwide. It provides a simple-to-use I/O bus in a
small card size (4.5 x 6.5-inches). The cards mount
securely in card cages that can tolerate shock and
vibration which makes them ideal for rugged industrial
applications.
STD Bus Card Cages & Backplanes - WinSystems has a
wide selection of backplanes, assembled card cages,
and powered
racks. These units are designed to provide the highest
integrity and reliability needed as a foundation for
an
embedded system.
The backplanes and card cages work with STD Bus
processors from the original Z80 to the newest Pentium
CPUs. WinSystems has correctly designed our back-planes
to minimize noise and crosstalk while maintaining
good power distribution, massive ground planes
and a constant characteristic impedance on the signal
lines. Our card cages do not require termination.
Termination adds unwanted capacitance and loads the
bus drivers which results in slower data transitions
and
skewed signals.
Three mounting configurations are available for card
cages: rack mount, table mount, or wall mount. Board
spacing is available in either 0.625 or 0.75-inches.
From
2 to 26 slots are available. All offer a vertical card
orientation
to take advantage of convection cooling. They are
constructed of aluminum for lightweight and strength.
WinSystems also offers card cages with 50W or 100W
power supplies. These are triple output, high-efficiency
supplies that mount inside the card cage. They are
universal
input switchers that accept a range of 110 to
220VAC. An ON/OFF switch and momentary Reset
switch are mounted on a panel for operator convenience.
Multiple backplanes and other options can be installed
in a card cage to allow more than one system to occupy
a single container. To configure and price a custom
backplane or card cage, contact the factory applications
engineer with your specification.
PC/104 Bus - The MCM/LPM-6117 has a 16-bit PC/104
connector. 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.
For more detailed information on the PC/104 Bus and
a
copy of the specification, refer to WinSystems' Volume
2
or Volume 3 Data Book or write the PC/104 Consortium.
Multi-I/O Connector - 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
5-pin
PS/2 connector socket.
SOFTWARE SUPPORT
Software Developers Kit - WinSystems offers
the SDK2-STD-CX15 software developers kit to supply
the necessary
hardware, software and cables to begin program
development with a STD Bus system. 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 supply
housed in an enclosure. A 15-slot, STD Bus card cage
is
mounted on top of the enclosure.
The power supply is a 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
