Description
Motorola MVME162-322
Technical Specifications
- Processor: 25MHz or 33MHz MC68040 microprocessor.
- Memory: Onboard DRAM, expandable.
- Communication: Two or four serial ports (EIA-232/422), optional 10Base-T Ethernet.
Functional Features
- Deterministic Performance: 68040 architecture provides predictable hard real-time control performance.
- Software Ecosystem: Fully supports classic RTOS such as VxWorks, pSOS, and OS-9.
- Drop-In Replacement: 6U VME size allows direct replacement of identical series modules in legacy systems.
Application Scenarios
Semiconductor manufacturing equipment (CVD, etching), railway transit subsystems, and Automated Test Equipment (ATE).
Performance Parameters
- Power Supply: Draws +5V from the VME backplane, typical current 3.5A.
- Boot Time: Optimized bootloader (162Bug) 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 for easy insertion and removal in dense racks.
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 to prevent induced interference.
