Description
Motorola MVME162-021
Technical Specifications
- Microprocessor: 25 MHz MC68040 with integrated FPU.
- Memory: 4MB parity-protected DRAM, 512KB SRAM.
- Communication: Dual serial ports (EIA-232-D and EIA-232-D/EIA-530).
- Network: Optional 10Base-T Ethernet with DMA.
Functional Features
- Seamless integration with VxWorks, pSOS, and OS-9 operating systems.
- Supports up to four single-width or two double-width IndustryPack modules.
- Provides deterministic real-time response for hard control loops.
- Includes on-board diagnostics and manufacturing test support.
Application Scenarios
Used in SCADA systems, automated test equipment (ATE), medical imaging systems, and power grid monitoring.
Performance Parameters
- Interrupt System: Seven-level VMEbus interrupter and handler.
- Bus Width: A16/A24/A32 addressing with D8/D16/D32/D64 data paths.
- Relative Humidity: 5% to 90% non-condensing.
Material Composition
Robust industrial components with lead-free or tin-lead soldering depending on manufacturing date.
Structural Characteristics
Standard 6U Eurocard dimensions with P1/P2 connectors and front panel I/O access.
Working Principle
Processes real-time interrupts from VMEbus or local IndustryPack I/O, executing control algorithms and updating outputs via DMA or polled I/O.
Installation Requirements
- Slide into VME slot and secure with front panel ejector handles.
- Configure serial port jumpers (J11) for DTE/DCE mode as required.
- Verify +5V backplane power stability before system boot.
Usage Precautions
- Do not exceed the maximum ambient temperature of 55°C without increased airflow.
- Handle the board by the edges to avoid damaging surface-mount components.
- Backup NVRAM configuration data before performing firmware updates.
