1 Introduction
The VSBC-6872 is an advanced VMEbus Single-Board Computer based on the Freescale MPC8270
PowerQUICC II processor. It is specifically designed to target embedded applications and features a
complete A32/D32 VMEbus interface with System Controller and Master/Slave capabilities. The VME
interface can be easily configured to fit a wide range of applications and to provide great flexibility at
system level for integration.
The Freescale MPC8270 offers an integrated solution to deal with high-end applications. Its low power
consumption level opens this system to a large range of network applications and system supervisions.
Three on-chip Fast Ethernet 10/100 Mbps controllers are available for standard network applications with
CAT5 cables.
Four high-speed multi-protocol serial links are also available. The Communication Processor Module
allows a management of several protocol types.
The memory controller supports SDRAM memory which offers a high-performance level for the system
executive core.
The non-volatile storage is based on Flash devices, which supports boot capability. The Flash memory is
organized in a two-bank structure. One bank of Flash, the on-board Real-Time Clock (RTC) and the
SRAM memory are accessible from the VMEbus through A24 slave access.
The Freescale MPC8270 has an on-chip 32-bit/66MHz PCI bridge used for connecting a dual S-ATA
controller and one PMC expansion module. The dual S-ATA controller can be used to connect mass
storage peripherals.
A CompactFlash card interface operating in True IDE mode offers an additional data storage capability.
The VSBC-6872 represents a flexible configuration, with one PMC module which can be used for
application extension. This PMC interface supports 32-bit modules, with a PCI clock frequency of 31.25 or
62.5 MHz. The VSBC-6872 can be customized through a wide range of PMC modules available from
ACTIS Computer or third-party manufacturers. The PMC module typical applications are network
controller, storage controller, acquisition system, etc.
Please refer to http://www.actis-computer.com/ for a complete list of available modules, or contact your
local ACTIS Computer representative.

2 Getting started
2.1 Unpacking instructions
If the shipping carton is damaged upon receipt, request that the carrier’s agent be present during the
unpacking and inspection of the equipment.
Unpack the equipment from the shipping carton. Carefully check the packing list and verify that all items
are present. Save the packing material for storing and reshipping of equipment.
Avoid touching areas of integrated circuitry; static discharge can damage circuits.
2.2 Hardware Configuration
To produce the desired configuration and ensure proper operation of the VSBC-6872, you may need to
carry out certain hardware modifications before installing the board.
The VSBC-6872 provides software control over most options: by setting bits in control registers after
installing the board in a system, you can modify its configuration.
For detailed specification and register setting, please consult the Freescale literature:
"MPC8260 PowerQUICC II™ Family Reference Manual"
"MPC8280 PowerQUICC II™ Specification"
“MPC8280 Hardware Specifications"
Some options are not software programmable. Such options are controlled through installation or removal
of jumpers or interface modules on the base board itself. For jumper configuration, please refer to 7.2
Board jumpers and 7.3 Serial Communication port jumpers.
2.3 Base board configuration
The Figure 3 shows the location of the connectors and jumpers on the VSBC-6872.
The VSBC-6872 is factory tested and shipped with the configurations described in the following sections.
The board’s factory-installed debug monitor operates properly with these factory settings.
2.4 Expansion module installation
The VSBC-6872 supports one PMC module. Please refer to 7.10.1 Installing a PMC for a detailed
installation procedure.
2.5 Board installation
Before installing the VSBC-6872 into a VMEbus backplane, make sure that the SLOT1 jumper is set
according to the slot location. If the VSBC-6872 is installed in slot 1 location, the System Controller must
be enabled and then SLOT1 jumper has to be plugged in. For all other locations, the System Controller of
the VSBC-6872 must be disabled and the SLOT1 jumper must be removed.

2.6 ECMon monitor
The VSBC-6872 is provided with an installed board monitor utility. It features debugging capability and
bootloader support with a user interface through a console port. It supports the primary board initialization
for memory and peripheral bus controllers, and offers an easy to use board setup for board support
package operation.
The ECMon debugger requires the use of the console port connected to a standard terminal. Please refer
to the Figure 3 - Component location - top assembly section to find the console port P5[D] connector. Use
the enclosed cable - part number CAB-RJ45-DB9 - which provides a direct connection to DB-9 female
connector.
The terminal equipment need to have the following setting: data = 8-bit/char, stop bit = 1, parity=none,
flow control=Xon/Xoff.
Terminal setting
Baud rate 9600 bps
Data bit 8-bit/char
Stop bit 1
Parity none
Flow control Xon/Xoff

3 Functional description
3.1 Freescale MPC8270 processor
The VSBC-6872 is based on the Freescale MPC8270 high-end PowerQUICC II processor which is
specifically designed to address embedded applications. This processor architecture offers a very
attractive design density by providing several on-chip peripheral controllers for a flexible Single Board
Computer product.
This chip contains a RISC processor core, SDRAM controller, 32KB RAM CACHE, one PCI bus interface,
three Ethernet interfaces, four multi protocol serial ports, one control for external memories and
peripherals, DMA function, two standard serial ports, one I
2
C interface, one SPI interface and general
purpose I/Os.
The PowerQUICC II features two standard on-chip buses: the 60x Bus and the Peripheral PCI Bus. The
60x bus is used to access all the memories (SDRAM, flash, SRAM) and other devices with CPU access
type (CompactFlash).
A Communication Processor Module manages the communication protocol of Ethernet ports and serial
ports.
