Architecture
CPU Chip
The Intel Celeron M processors have a new micro-architecture, but remain software
compatible with previous members of the Intel microprocessor family. The Celeron M has
longer pipeline stages and thus does more per clock cycle, which allows it to run at a lower
clock frequency thus saving power. The Celeron M has a large L2 cache (1MB on 160nm)
which boosts performance. A Celeron M is comparable in performance to a Pentium 4
running at 50% higher clock rate, but dissipates less than half the power. With a junction
temperature range of 0 to 100C, and a max power dissipation ranging from 10W to 24Watts,
the Celeron M is capable of withstanding a great deal of thermal stress while reducing the
overall power dissipation for the product.
PCI Local Bus Interface
The Intel 855GME / 6300ESB chipset supports the Celeron M processors with up to 400MHz front
side bus. The XVME 689-VR7 incorporates one PCI-X bus which is used to service the two Intel
82546EB Ethernet controllers and the on-board PMC site. The PMC site supports both 32-bit/33MHz
and 64-bit/66MHz bus speeds with 5V I/O support. The XVME 689-VR7 supports on PCI bus for 32-
bit/33MHz operation, this bus services the PCI to VME bridge chip known as the tundra Universe II
chip and the 80-pin expansion connector used to connect the XVME-976-209 Dual PMC carrier
modules. These carrier modules can be “stacked” to allow for up to five (5) PMC sites on one XVME
689-VR7.
PCI-X, or PCI extended, is an enhanced version of PCI (Peripheral Component Interconnect)
computer bus. Although PCI-X is backward-compatible with traditional PCI devices and systems, this
specification implements additional features and performance improvements include 3.3V signaling,
increased speed grades, and adaptation to other form factors. PCI-X effectively doubles the speed and
amount of data exchanged between the computer processor and peripherals. PCI-X bus was designed
for and is ideally suited for server cards such as Fibre Channel, RAID, high-speed networking, and
other demanding devices.
Onboard Memory
SDRAM Memory
The XVME 689-VR7 has a socket for a single 200-pin SODIMM, providing 256 MB, 512MB, 1GB
and 2GB of ECC DDR 266/333MHz SDRAM. Approved SDRAM suppliers are listed in 0.
Flash BIOS
The XVME 689-VR7 system BIOS is contained in a 1MB flash device to facilitate system BIOS
updates. Contact Xembedded support for available updates at [e-mail] if needed. Be
sure to record your current version number and the reason for the request.
Video Controller
The 855GME Graphics and Memory Controller Hub (GMCH) has a built-in 2D/3D graphics controller. The
maximum video modes supported are listed in the following table. The highest supported interlaced monitor
mode is 1280x1024, 16-bit/65k color, and 43 Hz. Video output is available on the front panel through a
standard 15-pin D shell connector. The graphics controller is in the 855GME which uses up to 64MB main

memory as video memory. The 855GME has a built-in 3D graphics engine and its display / render core
frequency is up to 200MHz.
Table 1-1 Maximum Video Modes Supported
Resolution Bit Depth/Colors Vertical Refresh
640x480 24-bit/16M color 100 Hz
800x600 24-bit/16M color 100 Hz
1024x768 24-bit/16M color 100 Hz
1280x1024 24-bit/16M color 75 Hz
1600x1200 16-bit/65k color 60 Hz
Ethernet Controller
The 82546GB dual Giga-bit Ethernet controller provides a pair of 10/100/1000baseT Ethernet interfaces. The
82546GB contains both the MAC and the physical layer. The RJ-45 connectors on the module's front panel
provide auto-sensing for 10Base-T, 100Base and 1000Base -TX connections. Each RJ-45 connector has two
indicator lights. When mounted vertically, the top light is the link/activity light and the bottom light (the one
closer to the COM ports) is the 10Base-T/100Base-TX indicator. When it is off, the connection is 10Base-T;
when it is on, the connection is 100Base-TX. When the Ethernet is switched to the rear optional P0 no lights
are available to indicate link or speed. The use of the XVME 990-VR7 is required to connect RJ-45 cables to
the rear of the XVME 689-VR7 processor boards.
Storage Devices (Hard Drive, Floppy, Compact PCI and On-Board Drive)
EIDE and Floppy Drives
The XVME 689-VR7 primary IDE and floppy drive signals are routed through the P2 connector inner three
rows (available in a legacy 96-pin back plane), providing a simplified method of connecting up to two IDE
devices and one external floppy drive. The secondary IDE master signals support the optional on-board hard
drive or on-board Compact Flash site and the secondary IDE slave signals are not supported.
The XVME-689-VR7 is NOT compatible with the XVME-977 and/or the XVME-979 mass storage modules.
For applications that require mass storage outside the VMEbus chassis, the XVME 9090-VR7 rear transition
module plugs onto the VMEbus J2 connector. This module provides industry standard connections for IDE and
floppy signals. One floppy drive can be connected to the XVME 990-VR7. This drive may be 2.88 MB,
1.44 MB, 1.2 MB, or 720 KB, 360 KB in size. For more information on the XVME 990-VR7, refer to Chapter
5.

Introduction

Caution
The IDE controller supports enhanced PIO modes, which reduce the cycle times for
16-bit data transfers to the hard drive. Check with your drive manual to see if the
drive you are using supports these modes. The higher the PIO mode, the shorter the
cycle time. As the IDE cable length increases, this reduced cycle time can lead to
erratic operation. As a result, it is in your best interest to keep the IDE cable as
short as possible.
The PIO modes can be selected in the BIOS setup. The Auto configuration will
attempt to classify the connected drive if the drive supports the auto ID command.
If you experience problems, change the Transfer Mode to Standard.
Caution
The total cable length must not exceed 18 inches. Also, if two drives are connected,
they must be no more than six inches apart. See SATA below for longer cable
lengths.
Serial ATA Hard Drive
The XVME 689-VR7 features two (2) SATA-150 drive interfaces out the rear P2 VMEbus connector. The
use of the optional rear transition module (XVME 990-VR7) allows for the connection of two drives using
standard SATA cables. If your application requires the external drives to be mounted in a location that
requires a long cable run, the SATA drives are better suited to that application. SATA cable can be up to 1
meters or 39” long, EIDE have be less than 18” long.
Serial ATA – 7-pin connector
The 0.5” wide cable connector directly connects the 4 signal wires and 3 ground lines to the receiving
terminal in a single row. Because the connector includes the shielding ground pins, very little crosstalk is
introduced. Note that the receiving terminal uses extended connectors for the 3 ground signals so that the
ground reference between the device and host can be shared prior to signals being applied at the input. A
similar mating sequence is enforced with the new 7/8” wide 15-pin single row power connector. This
feature is necessary to accommodate hot-plugging. The 7-pin plugs from both channels of the SATA-150
are on the XVME 990-VR7, the use of this rear transition module make it possible to connect to a SATA
drive. Contact www.serialata.org for more information on the SATA interface.
On-Board Hard Drive (Optional module XVME-913)
The on-board hard drive resides as a master on the secondary EIDE port. The XVME-913 is a kit of parts
including; 1.8” hard drive, cable, 4 brackets, screws and standoffs. There are no unique drivers required.
The XVME 689-VR7 can be booted from the on-board hard drive if configured in the BIOS Boot menu.
NOTE: The XVME 689-VR7 module can accept either an on-board 1.8” hard drive (XVME-913) or the
Compact Flash carrier (XVME-912) but not both.
Compact Flash Site (Optional module XVME-912)
The compact flash socket on the optional carrier module will support type I or type II Compact Flash cards.
The compact flash resides as a master on the secondary IDE port. There are no unique drivers required. The
XVME 689-VR7 can be booted from the compact flash drive if configured in the BIOS Boot menu. NOTE:
The XVME 689-VR7 module can accept either an on-board 1.8” hard drive (XVME-913) or the Compact
Flash carrier (XVME-912) but not both.

Introduction
1-5
VMEbus Interface
The XVME 689-VR7 uses the PCI local bus to interface to the VMEbus via a PCI to VME bridge device (Tundra
Universe IID). The VMEbus interface supports full DMA to and from the VMEbus, integral FIFOs for posted writes,
block mode transfers, and read-modify-write operations. The interface contains one master and eight slave images
that can be programmed in a variety of modes to allow the VMEbus to be mapped into the XVME 689-VR7 local
memory. This makes it easy to configure VMEbus resources in protected and real mode programs The XVME 689-
VR7 also incorporates onboard hardware byte-swapping (see Table 1-2). For a complete API, the Xembedded Board
Support Packages tailored to your operating system will allow quick programming of your application.
Serial and Parallel Ports
XVME-689-VR7 includes four high-speed 16550-compatible serial ports (RS-232C) with Com 4 capable of RS-232
and RS-422/485 configurations. The Parallel port can be configured for ECP or EPP parallel port. This is done in the
SMC SCH3114 LPC Super I/O and programmed via the BIOS. Com ports 1 and 4 are RJ-45’s on the front panel and
Com 2 and 3 are available out the P2 VMEbus connector and requires the use of the XVME-990-VR7 which
provides a standard DB-9 connection. The COM 4 port differ from front to back (P2), the front COM port 4 CAN
NOT be configured as a RS-232/422/485 but the rear P2 COM port 4 can be configured in this way.
Keyboard / Mouse Interface
A combined keyboard and mouse port PS/2 connector is provided on the front panel. A PS/2 splitter cable part
number 140232 (provided with the module) may be used to separate the two ports so that both devices may be
simultaneously connected to the module. IF a mouse is not required, a keyboard can be connected directly to the
PS/2 port. The keyboard and mouse are controlled in the SMC SCH3114 LPC Super I/O.
PMC Expansion
The XVME 689-VR7 provides an on-board PMC site for use with standard 32/64-bit, 33/66MHz PMC and PMC-X
modules. The PMC site is serviced by the on-board PCI-X bus. For electrical isolation, the PMC front panel bezel is
not connected to the main CPU ground. PCI-X, or PCI extended, is an enhanced version of PCI (Peripheral
Component Interconnect) computer bus. Although PCI-X is backward-compatible with traditional PCI devices and
systems, this specification implements additional features and performance improvements include 3.3V signaling,
increased speed grades, and adaptation to other form factors. PCI-X effectively doubles the speed and amount of data
exchanged between the computer processor and peripherals. PCI-X bus was designed for and is ideally suited for
server cards such as FPGA, DSP, Fibre Channel, RAID, high-speed networking, and other demanding devices. If a
standard PCI PMC card is fitted on the XVME 689-VR7 PMC site, the on-board PCI-X bus reverts to the PCI bus
speed.
Additional PMC Expansion Options
The XVME 689-VR7 supports optional PMC (PCI Mezzanine Card) expansion using XVME-976-209 expansion
module. The XVME-976-209 provides two PCI Mezzanine Card (PMC) sites. The XVME-976-209 module is
designed to plug directly into the XVME 689-VR7 using the 80-pin expansion board connector. Another XVME-
976-209 can be used to extend the XVME 689-VR7 and first XVME-976-209 to five PMC card sites.
Watchdog Timer
The XVME 689-VR7 has a long duration watchdog timer which can count from 1 to 255 seconds or from 1 to 255
minutes. The BIOS supports various system events which can be routed to the watchdog timer. The timer when
enabled can generate either an interrupt or a master reset depending on how the watchdog timer is configured.

Introduction

Note
The timeout range is from 1.0 second to 2.25 seconds; it will typically be 1.6
seconds.
Software Support
The XVME 689-VR7 is fully PC-compatible and will run "off-the-shelf" PC software, but most packages
will not be able to access the features of the VMEbus. To solve this problem, Xembedded has developed
extensive Board Support Packages (BSPs) that simplify the integration of VMEbus data into PC software
applications. Xembedded’s BSPs provide users with an efficient high-level interface between their
applications and the VMEbus-to-PCI bridge device. Board Support Packages are available for MS-DOS

Switch Settings
The XVME 689-VR7 has one four-pole switch (SW1) shown in Figure 2-2. The switches
functions are explained in table 2-2. This switch controls the system response to the front panel
Abort switch. Figure 2-2 shows the switch settings required to reset on the XVME 689-VR7
CPU, to reset only the VME backplane, or to reset both. The XVME 689-VR7 is shipped with
all four switches in the closed position (which causes the push button reset switch to reset both
the XVME 689-VR7 and the VME backplane).
Figure. 2-2
SW1 XVME 689-VR7 has a 4 position DIP switch to control the following functions.
Table 2-2 Four-Pole Switch (SW1) Functions

1 Do not respond to SYSRESET* Respond to SYSRESET*
2 Toggle switch does not cause SYSRESET* Toggle switch causes SYSRESET*
3 SYSFAIL* asserted on Power Up SYSFAIL* not asserted on Power
4 No local reset Toggle switch causes local reset
Registers
The XVME 689-VR7 modules contain the following Xembedded-defined I/O registers: 218h,
219h, 233h, and 234h.
