VMIVME-7750 Intel 133MHz Front-Side Bus Pentium III Processor - VMEBus SBC

VMIC’s VMIVME-7750 is a full-featured Pentium III compatible computer in a single-slot, passively cooled, Eurocard form factor that utilizes the advanced technology of Intel’s 815E chipset running at a front-side bus rate of 133 MHz. 

The VMIVME-7750 is compliant with the VME Specification Rev. C.1 and features a transparent PCI-to-VME bridge, allowing the board to function as a system controller or peripheral CPU in multi-CPU systems. The VMIVME-7750 provides features typically found on desktop systems such as: 

• Up to 512MB PC133 SDRAM 

• Built-in SVGA support with 4 Mbytes DRAM display cache 

• Built-in dual 10/100 Mbit Ethernet 

• IDE drive support 

• Floppy drive support 

• Two RS232 serial ports 

• Dual USB ports 

• Real-Time clock/calendar 

• Front panel reset switch 

• Miniature speaker 

• Keyboard/Mouse port 

The 815E chipset allows the VMIVME-7750 to provide enhanced features such as 133MHz front-side bus support and ATA-100 IDE support. 

The VMIVME-7750 is capable of executing many of today’s desktop operating systems such as Microsoft’s Windows 95, Windows 98SE, Windows NT 4.0, Windows 2000 and a wide variety of Linux-based operating systems. 

The standard desktop features of the VMIVME-7750 are described in Chapter 2 of this manual.

The VMIVME-7750 provides features useful to embedded applications such as: 

• I2C bus support 

• Remote Ethernet booting 

• Up to 512 Mbytes of bootable compact flash (optional) 

• Four general-purpose programmable timers (two 16-bit and two 32-bit) 

• Software-selectable Watchdog Timer with reset 

• 32KB Non-volatile SRAM 

Additionally, the VMIVME-7750 offers a PMC expansion site with front-panel access. The VMIVME-7750 is capable of executing many of today’s embedded operating systems such as VxWorks, QNX, Solaris, LynxOS and Microsoft’s embedded Windows NT. The embedded features of the VMIVME-7750 are described in Chapter 3 of this manual. 

The VMIVME-7750 is suitable for use in a variety of applications, such as: telecommunications, simulation, instrumentation, industrial control, process control and monitoring, factory automation, automated test systems, data acquisition systems and anywhere that the highest performance processing power in a single VME slot is desired.

Intel 815E Chipset The VMIVME-7750 incorporates the latest Intel chipset technology, the 815E. This chipset departs from previous generation devices by utilizing a new Advanced Hub Architecture (AHA). The AHA allows for increased system performance by separating many high-bandwidth I/O accesses (like IDE or USB devices) from PCI accesses, relieving bottlenecks on the PCI bus. Furthermore, the 815E chipset brings new levels of integration to motherboard chipsets and provides additional features (like ATA-100 support) over other chipsets.

The VMIVME-7750 requires +5V, +12V and -12V from the VME backplane. Below are the voltage and current requirements.

 Supply Current (Typical) Current (Maximum) +5V 5.8A 7A +12V 105mA 200mA -12V 50mA 75mA The VMIVME-7750 provides power to the PMC site in accordance with the PMC specification. The maximum current provided on the +5V supply is 1.5A per PMC site. The maximum current provided on the +3.3V supply is 1.5A per PMC site. The +12V and -12V supplies are provided to the PMC site and to the rear-transition board (such as the ACC-0562 board). The total +12v or -12v current provided to the VMIVME-7750 (as indicated above), the PMC site and the rear-transition board must not exceed 750mA each, in accordance with the VMEbus Specification.
