VMIVME-7805 / VME-7805RC VME Single Board Computers – Based on M4 Processor
Overview
The VMIVME-7805 / VME-7805RC are full-featured, Pentium-compatible Single Board Computers (SBCs) in a single-slot, passively cooled Eurocard form factor. Built on Intel's advanced 852GM chipset with a 400 MHz front-side bus, these boards deliver desktop-class performance in a rugged VMEbus environment.
Fully compliant with VMEbus Specification Rev. C.1, the VMIVME-7805/VME-7805RC feature a transparent PCI-to-VME bridge, enabling operation as either a system controller or a peripheral CPU in multi-CPU architectures.

Desktop-Class Features in a Single VME Slot
The VMIVME-7805/VME-7805RC bring capabilities typically found in desktop systems to embedded VME applications:
Up to 1 GByte PC1600 DDR SDRAM
Internal SVGA and DVI controller
Two built-in Ethernet controllers
IDE drive support (via VME P2)
Floppy drive support (via VME P2)
Two high-performance 16550-compatible serial ports (COM1 and COM2)
Front-panel USB 2.0 connection
Real-time clock/calendar
Front-panel reset switch
Miniature speaker
Keyboard/Mouse port
These boards are capable of running today's desktop operating systems, including Microsoft Windows and a wide variety of Linux distributions.
Embedded Application Features
For embedded and real-time applications, the VMIVME-7805/VME-7805RC offer:
I²C bus support
Remote Ethernet booting
Up to 1 GByte CompactFlash (optional)
Four general-purpose programmable timers (two 16-bit, two 32-bit)
Software-selectable Watchdog Timer with reset
32 KByte Nonvolatile RAM
Additionally, a PMC expansion site with front-panel access provides flexible I/O expansion.
The boards support leading embedded operating systems, including VxWorks®, LynxOS, and Microsoft Windows XP.
Intel 852GM Chipset: Optimized Graphics and Memory Performance
The VMIVME-7805/VME-7805RC incorporate the Intel 852GM chipset — an optimized integrated graphics solution featuring:
400 MHz processor system bus controller
Integrated 32-bit 3D core at 133 MHz with Dynamic Video Memory Technology (DVMT)
Graphics controller interface
One digital video out (DVO) port
DDR200 memory technology support
High-speed accelerated hub architecture for communication with the ICH4-M I/O controller.
Low-power design with advanced power management
Support for up to 1 GByte DDR system memory
The 852GM functions as a Graphics Memory Controller Hub (GMCH), providing the processor interface, system memory interface (DDR SDRAM), hub interface, and CRT/DVO output.
