Description
Motorola MVME162-026A
Technical Specifications
- Microprocessor: 25 MHz MC68040 with FPU.
- Memory: 4MB DRAM, 512KB SRAM.
- Network: Integrated 10Base-T Ethernet with DMA.
- Storage: SCSI-2 interface with DMA support.
Functional Features
- Drop-in replacement for legacy MVME162 systems.
- Supports VxWorks and pSOS for software continuity.
- Provides comprehensive board-level diagnostics.
- Features non-volatile configuration storage.
Application Scenarios
Used in semiconductor process tools, railway subsystems, and defense ground support equipment.
Performance Parameters
- Data Transfer: High-speed DMA for Ethernet and SCSI.
- Bus Support: A32/D64 VMEbus master/slave.
- Power: +5V from VME backplane.
Material Composition
Ruggedized PCB with conformal coating and industrial-grade connectors.
Structural Characteristics
6U VME form factor with front panel Ethernet and SCSI access (via transition module or direct).
Working Principle
Manages network and storage I/O via DMA, freeing the CPU for real-time control tasks while maintaining VMEbus communication.
Installation Requirements
- Use MVME712 transition module if standard I/O connectors are required.
- Ensure SCSI bus is properly terminated.
- Verify Ethernet link status via front panel LED.
Usage Precautions
- Do not exceed SCSI cable length specifications.
- Protect Ethernet ports from electrical surges.
- Regularly inspect and clean air filters in the VME chassis.
