VMIC VMIVME-9304 Single Board Computer

Module Feature

VMIC VMIVME-9304 is a single-slot 6U VMEbus single board computer powered by PowerPC 750FX processor running at 800 MHz, equipped with 32 KB L1 instruction cache,32 KB L1 data cache and 512 KB L2 cache. It supports up to 1 GB DDR memory via SODIMM socket, onboard 64 MB boot flash and CompactFlash storage slot for persistent application and OS image storage. Integrated 2D SVGA graphics controller supports max 1280×1024 resolution. Dual independent 10/100/1000BASE-T gigabit Ethernet ports provide redundant network communication. Serial interfaces include two software configurable RS232/422/485 channels with hardware flow control. Dual USB2.0 host ports and battery-backed real-time clock are integrated on the board. One PMC mezzanine expansion slot accepts 3.3 V /5 V PMC modules for analog I/O, fiber RFM or additional communication interfaces. VME64 bus compliance supporting A24/A32 addressing, D32/D64,BLT and MBLT64 block transfer modes. Programmable hardware watchdog timer can trigger NMI or full system reset for fail-safe operation. Rugged Eurocard construction, widely used in gas turbine control, hardware-in-loop simulation, aerospace test benches and high-reliability industrial VME chassis.

Working principle

PowerPC 750FX processor executes real-time operating system and user control application. VME64 bridge chip implements full VME master and slave capability to access registers and memory of other VME modules. PMC slot extends system function by mounting mezzanine I/O or communication boards. Dual gigabit controllers handle redundant Ethernet data transmission; multi-protocol UART chips drive configurable RS serial ports. Battery-backed RTC retains system time across power cycles. Flash and CompactFlash store boot firmware and application data. Hardware watchdog continuously monitors software heartbeat; timeout event triggers hardware reset or fault interrupt to avoid system hang. VME interrupt controller accepts interrupt signals from peripheral VME modules and forwards to PowerPC core.

Installation

Follow ESD safety procedure before handling. Fully power off VME chassis. Insert VMIVME-9304 into vacant 6U VME slot and lock front panel ejector latches. Install PMC mezzanine module if required. Connect front panel Ethernet, serial, USB and video peripherals. Power on chassis and enter bootloader to configure boot sequence and watchdog parameters. Install OS and VMIC VME drivers, run POST and full peripheral diagnostic before commissioning.

Interface

VME J1/J2 backplane connector, PMC mezzanine site, dual RJ45 gigabit Ethernet, dual DB9 serial ports, SVGA video, dual USB2.0, CompactFlash slot, fault status signal pins.

Diagnostic

Board fails POST: faulty SODIMM memory, defective CPU chip, insufficient chassis airflow or abnormal backplane power. VME block transfer unstable: poor backplane contact, missing bus termination, VME bridge hardware fault. Network link failure: damaged cable, PHY chip damage or duplex mismatch. RTC time loss: backup battery depletion. Watchdog fails to trigger: wrong bootloader watchdog parameter setup
