Description

Motorola MVME162-513

Technical Specifications

  • Processor: MC68040 or MC68LC040 32-bit microprocessor.
  • Memory: Onboard 1MB, 4MB, or 8MB parity-protected DRAM.
  • Non-Volatile Storage: 512KB SRAM (battery-backed) and 1MB Flash memory.
  • Communication Interfaces: Two serial ports (EIA-232-D and EIA-232-D/EIA-530), with optional LAN Ethernet and SCSI interfaces.

Functional Features

  • High-Precision Timing: Equipped with six tick timers with watchdog timers to ensure precise time measurement and event triggering.
  • High-Speed Bus Interface: Supports bidirectional data transfer between the local bus and VMEbus, featuring system controller functionality.
  • Data Integrity: Memory includes parity protection, combined with battery-backed SRAM, ensuring critical configuration parameters are not lost during power outages.
  • Multi-System Compatibility: Supports various embedded and real-time operating systems, including VxWorks and Linux.

Application Scenarios
Widely used in industrial automation control systems, precision instrument control, data acquisition systems, and legacy system maintenance requiring high reliability.

Performance Parameters

  • Bus Width: Supports A16/A24/A32 address space and D8/D16/D32 data widths.
  • Timing Precision: Features microsecond-level timing and interrupt response capabilities.

Material Composition
Constructed using industrial-grade multi-layer printed circuit boards (PCBs), populated with high-reliability integrated circuits, memory, and precision communication transceiver components.

Structural Characteristics
Standard 6U VME form factor (approximately 233 x 160 mm), featuring front-panel status indicator LEDs and debug interfaces, with slide-in installation support.

Working Principle
Upon power-up, the onboard firmware (162Bug) performs a self-test and loads the operating system. The processor communicates with other system modules via the VME bus and utilizes a DMA controller to achieve efficient data handling and execute real-time control logic.

Installation Requirements

  • Must be inserted into a compatible 6U VME backplane slot.
  • Ensure the system is completely powered off before installation and wear an anti-static wrist strap.
  • Ensure the chassis provides forced air cooling conditions.

Usage Precautions

  • Never insert or remove the module while powered on.
  • Regularly clean heat sink dust to ensure proper heat dissipation.
  • Charge the onboard backup battery before long-term storage to prevent NVRAM data loss.
