26 VMIVME-7807/VME-7807RC Hardware Reference Manual
2 • Standard Features
The VMIVME ‐ 7807/VME ‐ 7807RC are Pentium M processor ‐ based single board
computers compatible with modern industry standard desktop systems. The
VMIVME ‐ 7807/VME ‐ 7807RC 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, IDE drives, floppy
drives, 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
VMIVME ‐ 7807/VME ‐ 7807RC.
2.1 BGA CPU
The VMIVME ‐ 7807/VME ‐ 7807RC are factory populated with a Pentium M
processor.
To change the memory size or CompactFlash size contact Customer Care to
receive a Return Material Authorization (RMA).
2.2 Physical Memory
The VMIVME ‐ 7807/VME ‐ 7807RC provide DDR Synchronous DRAM (SDRAM)
as onboard system memory. Memory can be accessed as bytes, words or
longwords.
The VMIVME ‐ 7807/VME ‐ 7807RC accept one 200 ‐ pin DDR SDRAM SODIMM
along with the optional solder ‐ in 512 MByte onboard memory, for a maximum
capacity of 1.5 GByte. The onboard DRAM is accessible to the VME through the
PCI ‐ to ‐ PCI bridge and is addressable by the local processor.
NOTE
Memory capacity may change due to part availability.
