Technical Specifications:

 

  • Processor: Intel Ultra-Low Voltage Celeron at 400 MHz or 650 MHz, featuring a 100 MHz front-side bus and 256 KB on-die L2 cache for low-power, high-efficiency operation .
  • Memory: Up to 512 MB PC-100 SDRAM for system storage, with optional 1 GB bootable CompactFlash via the secondary IDE interface .
  • Interfaces:
    • VMEbus: Compliant with VME64 standards (A32/D32 addressing, MBLT/BLT protocols) for deterministic data transfer .
    • Communication: Two 10/100BASE-TX Ethernet ports, two USB 1.1 ports, and two RS-232 serial ports for connectivity .
    • Display: VGA output supporting 1600×1200 resolution with 4 MB dedicated video memory .
  • Expansion: One PMC slot for adding specialized I/O modules (e.g., analog/digital I/O, fiber-optic interfaces) .
  • Power: <25W total consumption, sourced via VMEbus (+5V DC) with reverse polarity protection .
  • Environmental:
    • Temperature: Operational range from -20°C to +70°C (-40°C to +85°C in extended variants), with some models (e.g., VME-7700RC) limited to 0°C to +70°C .
    • Shock/Vibration: Withstands 30g shock (11 ms duration) and 5g RMS vibration (10–500 Hz) .
    • Humidity: 5–95% RH (non-condensing) .
  • Mechanical: 6U VME form factor (233×167×28 mm) with passive cooling and rugged metal enclosure .

 

Functional Features:

 

  • Multi-CPU Architecture: Transparent PCI-to-VME bridge enables operation as a system controller or peripheral CPU in multi-processor configurations .
  • Real-Time Capabilities: Built-in watchdog timer and deterministic VMEbus communication for mission-critical applications .
  • Software Compatibility: Supports Windows 2000/XP, Linux, QNX, and VxWorks, with board support packages (BSPs) for driver integration .
  • Data Security: 32 KB non-volatile SRAM for parameter storage and BIOS settings .
  • Diagnostics: LED indicators for power status, Ethernet activity, and system health .
  • PMC Expansion: Single PMC slot allows customization with third-party modules for specialized I/O requirements .
