Product Short Description
Product Name
VMEbus Single-Board Computer (MC68030 Platform)
Product Overview
MVME167-33B is classic legacy 6U VME SBC based on MC68030 microprocessor, widely deployed in older industrial and military control systems. It provides stable low-to-medium performance computing for mature embedded applications.
Description
Technical & Performance Parameters
- Processor: MC68030, 33MHz, integrated MMU, no on-chip FPU
- Main Memory: 8MB soldered DRAM with parity detection
- Non-Volatile Memory: 512KB EPROM, 128KB lithium battery-backed SRAM and TOD clock
- Serial Interfaces: Multiple RS-232 asynchronous serial channels
- Bus Interface: VMEbus A24/A32, D8/D16/D32 transfer
- Operating Temperature: 0°C ~ 55°C
- Physical: 6U VME standard module
Functional Features
- Mature stable hardware design with decades of field operation history
- Programmable interval timers and system watchdog for fault recovery
- Supports legacy VME software stacks developed for MC68000 family processors
- Simple hardware configuration via DIP switches
Working Principle
MC68030 executes control firmware stored in EPROM. VMEbus interface communicates with other VME I/O modules. Serial ports connect to local operator terminals and remote monitoring equipment. Battery SRAM retains configuration parameters during power loss.
Application Scenarios
Legacy power station control systems, old railway signal equipment, marine legacy automation, factory production line retrofitting projects.
Usage Precautions
- Many units have reached end-of-service battery life; prioritize battery replacement before commissioning
- Spare parts supply is limited; avoid unnecessary hot swapping to reduce wear on backplane connectors
