Description

Motorola MVME162-833

Technical Specifications

  • Processor: 32 MHz enhanced 32-bit microprocessor.
  • Memory: 8MB ECC DRAM with hardware-level error detection and correction.
  • Processor Options: MC68040 with FPU or MC68LC040 without FPU.
  • VME Standard: Fully compliant with IEEE 1014-1987 (VMEbus).

Functional Features

  • Memory Error Correction: Automatically corrects single-bit memory errors and reports multi-bit errors, significantly reducing system crash rates.
  • Rich Peripherals: Integrated SCSI bus interface and Ethernet (LAN) transceiver interface, both supporting DMA.
  • Watchdog Mechanism: Built-in hardware watchdog timer automatically triggers a reset if the system locks up.
  • Multi-OS Support: Broadly compatible with VxWorks, OS-9, and other RTOS environments.

Application Scenarios
Nuclear power plant monitoring, medical equipment control, precision instrument manufacturing, and defense/military applications requiring extreme data accuracy.

Performance Parameters

  • Interrupt Handling: Supports up to 7 VME interrupt request levels and interrupt handling mechanisms.
  • DMA Performance: Supports VMEbus D16/D32/D64 BLT (Block Transfer) modes for high-throughput data transfers.
  • Physical Dimensions: With front panel: Height 261.85mm, Depth 188mm, Thickness 20.32mm.

Material Composition
High Tg-value PCB material, IPC-A-610 industrial-grade soldering standards, and radiation-tolerant or industrial wide-temperature packaged critical chips.

Structural Characteristics
Front panel provides standard VME ejector handles for safe insertion/extraction in dense racks. Rear P2 connector supports additional I/O signal routing.

Working Principle
During boot, 162Bug firmware runs POST, initializes the ECC DRAM controller and VME interface. The RTOS then uses VMEchip2 to respond to external interrupts and MCchip to manage onboard Ethernet and SCSI devices.

Installation Requirements

  • Verify backplane P1/P2 connector pin definitions match board requirements.
  • Ensure proper ejection handle engagement during installation.

Usage Precautions

  • Never hot-swap the board.
  • Regularly inspect front-panel connectors, ejector handles, and backplane contacts.
  • Keep firmware and OS BSP versions aligned.
