2 • Standard Features

The V7768/V7769 are single board computers loaded with either an Intel Core 2 

Duo or Celeron M processor and compatible with modern industry standard 

desktop systems. The V7768/V7769 therefore retain industry standard memory 

and I/O maps along with a standard interrupt architecture. The integrated 

peripherals described in this section (such as serial ports, USB ports, 

CompactFlash drive, video controller and Ethernet controller) are all memory 

mapped the same as similarly equipped desktop systems, ensuring compatibility 

with modern operating systems.

The following sections describe the standard features of the V7768/V7769.

2.1 BGA CPU

The V7768 is factory populated with either an Intel Core 2 Duo or Celeron M 

processor. The V7769 is factory populated with an Intel Core 2 Duo processor.

2.2 Physical Memory

The V7768/V7769 provide DDR2 Synchronous DRAM (SDRAM) as system 

memory. Memory can be accessed as bytes, words or longwords. 

The SDRAM is accessible to the VME bus through the PCI-to-VME bridge and is 

addressable by the local processor.

The V7768/V7769 have a maximum memory configuration of 2 GByte of DDR2 

SDRAM memory. This configuration calls for a single 2 GByte SODIMM (one 

200-pin SODIMM DDR2 module). The SDRAM is dual-ported to the VME 

through the PCI-to-VME bridge and is addressable by the local processor, as well 

as the VME slave interface by another VME master. Caution must be used when 

sharing memory between the local processor and the VME to prevent a VME 

deadlock and to prevent a VME master from overwriting the local processor’s 

operating system.

NOTE

When using the Configure utility of GE’s IOWorks Access to configure RAM, do not request more 

than 25 percent of the physical RAM. Exceeding the 25 percent limit may result in known bugs that 

causes unpredictable behavior during the boot sequence, and requires the use of an emergency 

repair disk to restore the computer. It is recommended that an emergency repair disk be kept upto-date and easily accessible.
