Description

Motorola MVME162-020A

Technical Specifications
  • Microprocessor: 25 MHz MC68040 with FPU and MMU.
  • Memory: 4MB DRAM, 512KB battery-backed SRAM.
  • Non-Volatile Storage: 8KB NVRAM with real-time clock (RTC) and watchdog.
  • Expansion: Four IndustryPack ports with dedicated DMA channels.
Functional Features
  • Integrated 162Bug monitor/debugger for system diagnostics.
  • Supports VMEbus D64 block transfers for optimized throughput.
  • Provides seven-level interrupt handling and four-level requestor.
  • Features Global Control and Status Registers (GCSR) for multiprocessor communication.
Application Scenarios
Ideal for military ground systems, aerospace test stands, railway signaling, and heavy industrial machinery control.
Performance Parameters
  • DMA Support: High-performance DMA for VMEbus D64 and local bus memory burst cycles.
  • Serial I/O: Dual asynchronous channels supporting EIA-232/422 protocols.
  • Storage Temperature: -40°C to +85°C.
Material Composition
High-Tg printed circuit board with gold-plated VME edge connectors and industrial-grade capacitors.
Structural Characteristics
Double-high 6U VME board with front panel status LEDs (RUN, FAIL, STAT) and manual reset/abort buttons.
Working Principle
Executes boot firmware from Flash, initializes hardware, and loads the real-time operating system (RTOS). The CPU coordinates with the VMEChip2 to manage bus arbitration and data routing.
Installation Requirements
  • Verify system controller jumper settings (J1) if used as the VME arbiter.
  • Ensure adequate clearance for IndustryPack modules if installed.
  • Connect chassis ground properly to minimize EMI.
Usage Precautions
  • Keep SCSI ribbon cables within specified lengths if the SCSI option is utilized.
  • Route serial communication lines away from high-noise power cables.
  • Perform routine inspection of backplane contacts for oxidation.
