Description
Motorola MVME162-523
Technical Specifications
- Processor: 25MHz or 33MHz MC68040.
- Memory: Onboard DRAM, expandable.
- Communication: Two or four serial ports, optional 10Base-T Ethernet.
- Timers: Six tick timers with watchdog.
Functional Features
- Deterministic Performance: 68040 architecture provides predictable hard real-time control performance.
- Drop-In Replacement: 6U VME size allows direct replacement of identical series modules in legacy systems.
- High-Precision Time Control: Suitable for applications requiring precise timing control.
- Onboard Debugging: Simplifies system maintenance and troubleshooting.
Application Scenarios
Industrial automation, data acquisition, precision instrument control, and critical infrastructure monitoring.
Performance Parameters
- Power Supply: Draws +5V from the VME backplane, typical current 3.5A.
- Boot Time: Optimized bootloader reduces system startup time.
Material Composition
High Tg-value PCB material adapts to long-term high-temperature operation environments.
Structural Characteristics
Equipped with standard VME extraction handles and front-panel status indicator LEDs.
Working Principle
Executes onboard firmware self-test upon power-up, loads the RTOS, and responds to external events via the VME interrupt mechanism.
Installation Requirements
- Ensure stable +5V backplane power supply with ripple below 50mV.
- Check chassis grounding and follow ESD protection protocols.
Usage Precautions
- Maintain version consistency between firmware (162Bug) and OS BSP.
- Route serial cables away from high-voltage power lines.
