MVME167-02B MOTOROLA VME bus single-board computer

Performance characteristics

I. High-performance processing capability

Powerful processor configuration

Equipped with the MC68030 enhanced 32-bit microprocessor of 16/25/33.33MHz, it belongs to the high-performance RISC architecture processor, supporting 32-bit data and address processing, and can efficiently handle complex operations and multi-task scheduling.

Optional 16/25/33.33MHz MC68882 floating-point coprocessors are available, significantly enhancing the floating-point operation speed (such as in scientific computing, signal processing, and other scenarios). Compared with the solution without coprocessors, the operation efficiency is increased by approximately 30% to 50%.

Flexible memory expansion

Supports shared DRAM ranging from 4MB to 32MB, and can be adapted to different task requirements through programmable Settings. For example, in industrial automation, multiple control programs and data caches can be run simultaneously.

Equipped with 4K x 8 SRAM and a battery-powered clock, it ensures that system time and key configuration data are not lost after power failure (such as parameter recovery after the restart of industrial equipment).

Ii. High reliability and stability design

Industrial-grade environmental adaptability

The operating temperature range is from 0°C to 55°C, meeting the temperature requirements of most industrial scenarios such as workshops and outdoor equipment. Compared with commercial-grade equipment (0°C to 40°C), it is more resistant to high temperatures.

It adopts MOTOROLA industrial-grade components, with strong anti-vibration and anti-interference capabilities, and is suitable for fields with extremely high reliability requirements such as aerospace and transportation (such as aircraft on-board control systems and high-speed rail signal processing).

Data persistence and fault-tolerance mechanism

The battery-powered clock and SRAM ensure that the system maintains real-time clock and critical configurations after power failure, avoiding program interruptions or parameter loss caused by power outages (such as in the continuous monitoring scenario of medical equipment).

Iii. Rich interfaces and scalability

High-speed communication on the VME bus

Supports A32/D32 VMEbus master/slave interfaces, with a maximum data transmission rate of up to 40MB/s (at a 33MHz clock), and can achieve high-speed data interaction with other modules in the VMEbus system (such as I/O modules and storage modules). It is suitable for scenarios that require real-time data transmission (such as multi-device collaborative control in industrial automated production lines).

Diversified external interfaces

Serial port: 4 EIA-232-D interfaces, which can be connected to devices such as sensors, PLCS, and serial printers. For example, in industrial monitoring, multiple temperature/pressure sensors can be connected for data collection.

Parallel port: Centronics printer port, supporting high-speed print output, suitable for industrial report generation or real-time data printing of medical equipment.

Storage expansion interfaces: 4 28/32-pin ROM/PROM/EPROM/EEPROM interfaces, which can expand program storage or data storage (such as solidifying industrial control programs, saving historical data).

Iv. Accuracy and Flexibility of Analog Output

High-precision analog output

Current output: 0~20mA range, resolution 0.625μA (12-bit accuracy), accuracy ±0.1% of full scale at 25°C, suitable for instrument control in industrial sites (such as valve opening adjustment, motor speed control).

Voltage output: Bipolar (-10 to +10V) or unipolar (0 to +10V), resolution 0.3125mV (12-bit), accuracy ±0.25%, capable of driving analog input devices or signal conditioning modules (such as waveform output for medical equipment).

Programmable configuration

Supports software configuration of analog output mode (current/voltage) and range, allowing for adaptation to different load requirements without hardware modification and enhancing system flexibility (similar to switching control modes for the same device across different production lines).

V. Universality and Ecological Advantages of the VME Bus Standard

Standardized architecture

The VME bus is a classic standard bus in the field of industrial control, featuring unified electrical and mechanical specifications. It facilitates seamless integration with other VME modules (such as digital I/O and communication modules), reducing system development and maintenance costs (for instance, in large-scale industrial control systems, modules can be directly replaced or expanded without the need to redesign the architecture).

Long life cycle support

MOTOROLA, as a leading manufacturer of VME bus devices, provides long-term technical support and spare parts supply for MVME167-02B, which is suitable for scenarios with high requirements for the equipment life cycle (such as aerospace equipment, with a service life of more than 10 years).

Six. Low power consumption and compact design

Low-power architecture

The MC68030 processor adopts a low-power design and, in combination with optimized power management, has an overall power consumption of less than 15W (under typical working conditions), making it suitable for environments with strict heat dissipation requirements (such as closed cabinets and mobile devices).

Compact veneer form

Adopting standard VME single board sizes (such as 6U or 3U), it occupies a small space and can build high-density systems (such as shipborne equipment and rail transit control cabinets) within a limited space.

Vii. Summary of Advantages in Application Scenario Adaptation

Industrial automation: With high reliability and real-time performance, it is used in production line control, robot collaboration, process monitoring, etc., and supports high-speed communication among multiple devices and analog control.

Aerospace: Resistant to harsh environments and long life cycle support, suitable for airborne data processing and satellite ground station equipment.

Medical equipment: High-precision analog output can be used for waveform generation of monitors, control of medical instruments, and data retention in case of power failure to ensure uninterrupted diagnosis and treatment processes.

Transportation: In high-speed rail signal systems and metro monitoring, it meets the requirements of high reliability and anti-vibration to ensure the safe operation of transportation.
