Description

Motorola MVME162-512C

Technical Specifications

  • Microprocessor: 32 MHz MC68040 enhanced 32-bit processor featuring an 8KB cache, Memory Management Unit (MMU), and Floating-Point Unit (FPU).
  • Memory: 4MB shared DRAM (expandable up to 16MB) and 512KB SRAM with battery backup.
  • Storage: 1MB Flash memory for onboard monitor/debugger firmware.
  • Interfaces: Dual serial ports (EIA-232-D and EIA-232-D/EIA-422), four IndustryPack ports, optional Ethernet, and SCSI.

Functional Features

  • Supports VMEbus A32/D64 block transfers and system controller functionality.
  • Features high-performance DMA for local bus memory burst cycles.
  • Includes six 32-bit timers and a watchdog timer for system reliability.
  • Provides remote RESET, ABORT, and STATUS control functions via the VMEbus.

Application Scenarios
Widely deployed in industrial automation, data acquisition stations, large-scale equipment control nodes, and telecommunications switching systems.

Performance Parameters

  • Bus Interface: A32/D64 VMEbus master/slave interface.
  • Power Requirements: +5V at 3.5A typical (4.5A max), ±12V at 100mA max.
  • Operating Temperature: 0°C to +55°C with forced air cooling.

Material Composition
Constructed with industrial-grade multi-layer PCBs, high-reliability CMOS components, and optional conformal coating for protection against harsh environments.

Structural Characteristics
Standard 6U VME form factor (233.35mm x 160.00mm) with P1/P2 backplane connectors, front panel status LEDs, and manual reset/abort pushbuttons.

Working Principle
The MC68040 CPU manages local memory and peripherals via a high-speed local bus. The VMEChip2 ASIC arbitrates and routes data across the VME backplane, while IndustryPack interfaces provide direct connections to external physical I/O modules.

Installation Requirements

  • Insert into a standard 6U VME chassis with proper card guides and secure with front panel screws.
  • Requires unobstructed forced air cooling (typically 100 CFM airflow).
  • Ensure strict adherence to backplane power (+5V, ±12V) and grounding specifications.

Usage Precautions

  • Strictly observe ESD (Electrostatic Discharge) handling procedures during installation.
  • Never insert or remove the board while system power is applied.
  • Periodically clean heat sinks and fans to prevent thermal throttling.
