Description

The GE VMIVME-7807RC (also designated as VME-7807RC-424001, with full manufacturer part number 350-93007807-424001-K) is a high-reliability, conduction-cooled VME64x single-board computer (SBC) based on the PowerPC 750FX RISC processor. Developed by VMIC and later maintained under GE Intelligent Platforms (now part of Emerson), this module targets mission-critical embedded applications in defense, aerospace, nuclear power, rail signaling, and industrial automation—where long lifecycle support, deterministic real-time performance, and environmental ruggedness are paramount.

Operating at up to 700 MHz, the VMIVME-7807RC integrates 512 MB of DDR SDRAM with ECC (Error-Correcting Code) for data integrity, 16 MB of Boot Flash, and dual 10/100/1000BASE-T Ethernet ports via onboard Marvell controllers. It features a 64-bit/66 MHz VMEbus interface compliant with ANSI/VITA 1.1 (VME64x), supporting both A24/A32 addressing and D16/D32/D64 data transfers, enabling high-throughput communication with other VME modules in data acquisition or control chassis.

Designed for harsh environments, the VMIVME-7807RC supports conduction cooling (ideal for sealed or forced-air-free systems) and operates across an extended temperature range of -40°C to +70°C. It includes hardware-level reliability features such as a watchdog timer, real-time clock (RTC), and PMC (PCI Mezzanine Card) site for I/O expansion (e.g., serial, CAN, or FPGA-based custom interfaces).

This SBC is commonly deployed in legacy and modernized control systems that require decades-long availability—such as turbine protection in power plants, radar signal processing in military vehicles, or safety interlocks in nuclear facilities—where software stability on real-time operating systems like VxWorks, LynxOS, or LinuxPPC is essential.

Technical Specifications

Main Features and Advantages

✅ Real-Time Performance: The PowerPC 750FX core delivers deterministic interrupt response and low-latency I/O handling—critical for closed-loop control and high-speed data acquisition.

✅ High Reliability & Data Integrity: ECC memory prevents silent data corruption caused by cosmic rays or electrical noise—essential in safety-critical and remote installations.

✅ Long-Term Availability: GE/VMIC historically provided >15-year lifecycle support for VME products, making the VMIVME-7807RC a trusted choice for systems requiring decades of operation without redesign.

✅ Rugged Mechanical Design: Conduction-cooled variant eliminates fans, enabling use in dusty, explosive, or vacuum environments (e.g., submarines, space simulators, oil rigs).

✅ Flexible I/O Expansion: The integrated PMC site allows customization—adding ARINC-429, MIL-STD-1553, CANbus, or custom FPGA logic without consuming VME slots.

✅ Legacy & Modern OS Compatibility: Proven driver support across major real-time operating systems ensures smooth integration into both brownfield upgrades and new developments.

Application Field

Installation & Maintenance Tips

• Cooling: Ensure proper thermal contact between the board’s conduction frame and the chassis cold plate—use thermal grease if required.

• Firmware: Update the onboard BIOS (POST code monitor) to the latest version for improved VME arbitration and error reporting.

• OS Drivers: Use GE-provided BSPs (Board Support Packages) for VxWorks/Linux to ensure optimal DMA and interrupt handling.

• Redundancy: In critical systems, deploy dualVMIVME-7807RC units with shared storage or heartbeat monitoring for failover.

• Obsolescence Planning: Although still available through authorized distributors, consider migration paths to VPX or CompactPCI-SI if designing new systems.
