Description
Motorola MVME162-021A
Technical Specifications
- Microprocessor: 25 MHz MC68040 with 8KB cache and FPU.
- Memory: 4MB DRAM, 512KB battery-backed SRAM.
- Firmware: 1MB Flash for 162Bug and user applications.
- I/O Expansion: Four 16/32-bit IndustryPack ports.
Functional Features
- Advanced DMA controller for fast local memory to VMEbus transfers.
- Integrated real-time clock with battery backup.
- Supports network boot and remote debugging.
- Provides comprehensive error reporting via front panel LEDs.
Application Scenarios
Deployed in nuclear power plant instrumentation, offshore oil rig controls, and defense communication systems.
Performance Parameters
- Task Switching: Low-latency context switching for multitasking RTOS.
- Bus Arbitration: Supports VMEbus system controller functions.
- Power Dissipation: Typical 20W, dependent on configuration.
Material Composition
Multi-layer FR4 PCB with gold-plated edge fingers and conformal coating for moisture resistance.
Structural Characteristics
6U VME form factor with front panel indicators for RUN, FAIL, SCON, LAN, SCSI, and FUSE status.
Working Principle
The system boots from Flash or network, initializes the MC68040 and VMEChip2, and begins executing the application code while managing hardware interrupts.
Installation Requirements
- Ensure the VME chassis provides adequate cooling airflow (minimum 10 CFM).
- Check that the backplane P2 connector supports required I/O signals.
- Secure all external cables to prevent strain on front panel connectors.
Usage Precautions
- Monitor the FUSE LED; if illuminated, check for backplane short circuits.
- Replace the SRAM battery every 3-5 years to maintain data integrity.
- Avoid operating in environments with high levels of conductive dust.
