EMERSON MOTOROLA MVME-147SRF / MVME147SRF MPU VME MODULE

MOTOROLA MVME147SRF MPU VME Module

Introduction

The MOTOROLA MVME147SRF is a high-performance, single-board computer (SBC) belonging to the legendary MVME147 series.

Built on the 68030 microprocessor architecture, the "SRF" variant is a specialized version of the MVME147S series.

It is designed for high-reliability industrial control and real-time processing within a 32-bit VMEbus environment.

The module integrates a full suite of I/O functions, including SCSI, serial, and parallel interfaces, making it a complete "computer on a board" for legacy automation and defense systems.

Related Models

MVME147-010: The standard 16MHz base model without Ethernet/Parity.

MVME147S-1: 25MHz version with 4MB/8MB RAM and Ethernet support.

MVME147SA/SB/SC: High-performance variations with up to 32MB RAM and 32MHz clock speeds.

MVME712M: The recommended Transition Module for external I/O cabling.

Application Cases

Legacy CNC Control: Providing the core processing power for large-scale milling and metallurgy machines that require stable VMEbus architecture.

Petrochemical Monitoring: Used in refineries for real-time data acquisition where serial communication with field sensors is critical.

Aerospace Defense: Integrated into ground support equipment and simulators that rely on the deterministic performance of the 68030 processor.

Power Distribution: Managing substation automation protocols via multi-channel serial interfaces.

Product Advantages and Features

Integrated Versatility: Consolidates a CPU, FPU, SCSI controller, and four serial ports onto a single 6U card, reducing the need for multiple peripheral boards.

Deterministic Real-Time Performance: The MC68030/68882 combination excels in executing complex mathematical algorithms for industrial motion control.

Rugged VME Design: Designed for harsh environments, featuring high tolerance for vibration and a wide operating temperature range (0°C to 55°C with forced air).

Simplified I/O: All major I/O is routed through the P2 connector, allowing for easy integration with transition modules like the MVME712M for rear-panel access.

Installation and Maintenance

Installation: Ensure the module is seated in Slot 1 if acting as the System Controller. 

Verify jumper header J3 (on SRF models) is configured correctly for your backplane power and interrupt requirements.

Firmware: The SRF model typically utilizes the 147Bug debugging and diagnostic package. Ensure the EPROMs are correctly seated in sockets U22 and U30.

Maintenance: Due to the age of these modules, the battery-backed Timekeeper RAM (M48T02/18) may require replacement to retain system configuration.

 Always use ESD protection when handling.

Unique Product Description

The MOTOROLA MVME147SRF is the backbone of "tried and true" industrial automation.

While newer platforms focus on high-speed consumer standards, the MVME147SRF prioritizes stability and longevity.

It is the ideal solution for maintaining systems where Ethernet is not required, focusing instead on pure processing power and reliable SCSI/Serial throughput.

For engineers maintaining critical infrastructure, the SRF version offers a streamlined, "no-nonsense" VME solution that has proven its reliability over decades of service.
