Description
Motorola MVME330
Technical Specifications
- Processor: Based on the high-performance Motorola 680×0 series microprocessor architecture.
- Bus Standard: Fully compliant with the IEEE 1014 (VMEbus) standard.
- Memory Architecture: Supports DRAM with parity checking or ECC error correction.
- Non-Volatile Storage: Equipped with battery-backed NVRAM for saving system configurations and real-time clock data.
Functional Features
- System Controller Function: Capable of acting as the VME chassis system controller, managing bus arbitration and interrupts.
- Multiprocessor Support: Hardware design facilitates multiprocessor collaboration for seamless system expansion.
- Rich Peripheral Interfaces: Integrates serial communication, Ethernet, and local I/O interfaces to meet diverse application needs.
Application Scenarios
- Process Control: Distributed Control Systems (DCS) in oil refining, chemical, and power generation industries.
- Test and Measurement: Host controller module for Automated Test Equipment (ATE).
- Defense and Transportation: Ruggedized military computing platforms and railway signaling control systems.
Performance Parameters
- Bus Throughput: Supports multiple VMEbus data transfer modes to ensure high-bandwidth data exchange.
- Reliability: Features a high Mean Time Between Failures (MTBF), adapting to 7×24-hour uninterrupted operation.
Material Composition
Constructed with industrial-grade wide-temperature electronic components, a high-reliability PCB substrate, and a long-life backup battery.
Structural Characteristics
- Board Specification: Standard 6U or 3U VME dimensions (depending on the specific sub-model).
- Panel Design: Equipped with standard VME extractor handles and status indicator LEDs.
Working Principle
The processor executes real-time operating system instructions, accessing memory and peripherals via the local bus. The VME interface logic maps local resources into the VME address space, allowing other master modules in the chassis to directly access this board’s resources.
