Description
Motorola MVME162-263
Technical Specifications
- Processor: MC68040 or MC68LC040 microprocessor.
- Memory Configuration: Onboard 1MB, 4MB, or 8MB parity-protected DRAM.
- Non-Volatile Storage: 512KB SRAM (battery-backed) and 1MB Flash memory.
- Interface Configuration: 4 IndustryPack interfaces, each with a dedicated DMA channel.
Functional Features
- Modular Expansion: Supports up to 4 single-width or 2 double-width IndustryPack modules for flexible I/O configuration.
- System Control: Functions as a VMEbus system controller, supporting A32/D64 data transfers.
- High-Precision Sampling: Achieves ±1ms sampling accuracy in power monitoring systems.
- Status Monitoring: Front panel features four status LEDs: FAIL, RUN, SCON, and FUSES.
Application Scenarios
Widely applied in substation automation systems, process control, robotics, and test/measurement equipment requiring high-precision data acquisition.
Performance Parameters
- Interrupt Handling: Equipped with a 4-level requestor, 7-level interrupter, and interrupt handler.
- Timers: Includes six 32-bit timers (four without VMEbus) and a watchdog timer.
Material Composition
High-reliability industrial-grade PCB with impedance-matched critical signal traces and conformal coating.
Structural Characteristics
Standard 6U VME size, featuring physical ABORT and RESET buttons on the front panel for convenient field debugging and emergency resets.
Working Principle
Acts as the core controller of the VME system, reading field data from IndustryPack modules via VME bus polling or interrupts. After internal logical processing, it issues control commands to actuators.
Installation Requirements
- Align with the guide rails and apply even pressure when inserting into the VME slot.
- Ensure front-panel buttons are not obstructed by the chassis panel.
Usage Precautions
- Check memory expansion module compatibility if the system experiences frequent reboots.
- Regularly verify the connection status of IndustryPack modules to prevent loosening due to vibration.
