Description
Motorola MVME167-04
Technical Specifications:
- Brand: Motorola
- Model: MVME167-04
- Processor: MC68040 32-bit Microprocessor
- Clock Speed: 33MHz
- Memory: Up to 128MB ECC-protected DRAM
- Bus Standard: Full 32-bit Master/Slave VMEbus with Block Transfer (BLT)
Functional Features:
- Ultimate Data Integrity: Features ECC-protected DRAM to automatically detect and correct single-bit errors, ensuring absolute data safety.
- Rich I/O Suite: Includes four DMA-enabled serial ports, a Centronics parallel port, a SCSI interface, and an Ethernet transceiver interface.
- Real-Time Execution: Equipped with four 32-bit tick timers and a hardware watchdog timer to guarantee precise task execution and automatic system recovery.
Application Scenarios:
Widely utilized in large automated testing platforms (ATE), advanced radar signal processing, nuclear power plant safety monitoring, and aerospace testing equipment.
Performance Parameters:
- Processing Speed: 33MHz clock speed combined with 128MB ECC memory delivers highly efficient data throughput and floating-point concurrency.
- System Monitoring: Front panel status LEDs (FAIL, STAT, RUN, SCON, LAN) provide instant visual feedback on system health.
Material Composition:
Constructed with multi-layer industrial-grade flame-retardant PCB substrates. Core components are strictly screened for wide-temperature operation and coated with conformal coating to resist moisture, salt spray, and mold.
Structural Characteristics:
Standard 6U VME form factor featuring a robust metal heat dissipation frame and standard VME P1/P2 edge connectors. The front panel provides a debug serial port and status indicators.
Working Principle:
Upon power-up, the MC68040 processor executes the boot firmware and loads the real-time operating system. It communicates with external I/O modules via the VME bus at high speeds, utilizing ECC memory to ensure accurate execution of complex control algorithms.
Installation Requirements:
The board must be smoothly inserted into a VME-compliant chassis backplane slot, ensuring connectors are fully engaged. VME address and interrupt request jumpers must be correctly configured according to system planning.
Usage Precautions:
Operators must wear anti-static wrist straps during handling. Hot-swapping the board while the system is powered on is strictly prohibited. Ensure the chassis interior has sufficient forced-air cooling to meet the processor’s thermal dissipation requirements.
