Product Introduction

The **Motorola MVME 162-23** is a reliable entry-to-mid-range 3U VMEbus Single-Board Computer (SBC) powered by the MC68030 processor, designed for legacy industrial automation and embedded control applications. As a practical model in Motorola’s MVME162 series, it combines stable 68000-series processing performance with essential connectivity and expansion capabilities, serving as a cost-effective core control unit in moderate-complexity legacy automation systems.

Equipped with 8 MB DRAM (expandable to 16 MB) for data processing, 1 MB EPROM for firmware storage, and 32 KB SRAM for cache, the **Motorola MVME 162-23** ensures smooth execution of standard real-time control algorithms. Its single RS-232C port enables serial connectivity with peripheral devices, while the Centronics parallel port supports printer or basic high-speed I/O connections. The single Industry Pack (IP) port allows modular expansion for application-specific needs. With a wide operating temperature range of -40°C to +85°C and compliance with VMEbus standards, this module seamlessly integrates into harsh industrial environments and legacy VME ecosystems.

Core Advantages & Technical Highlights

Stable 68030 Processing: The 25 MHz MC68030 processor with MMU delivers reliable computational power optimized for moderate legacy real-time control tasks. Its 32-bit architecture ensures efficient handling of data and instructions, enabling the **Motorola MVME 162-23** to run mature control algorithms without software overhauls—ideal for maintaining or upgrading entry-to-mid-range legacy automation systems.

Balanced Memory & Connectivity: The 8 MB DRAM (expandable to 16 MB) provides sufficient space for running typical industrial applications and storing process data. Essential communication interfaces (1 x RS-232C, 1 x Centronics parallel) offer seamless connectivity with common legacy peripherals, eliminating the need for extra adapters and simplifying system integration.

Cost-Effective Expansion: One Industry Pack port allows addition of specialized I/O modules (e.g., analog I/O, digital I/O, communication cards), providing targeted scalability to adapt to evolving application needs without replacing the core SBC. This modularity balances functionality and cost, extending the product’s lifecycle in budget-conscious industrial environments.

Reliable VMEbus Integration: The VMEchip1 controller supports 32-bit VMEbus data transfers and functions as both master and slave, enabling efficient communication with other VMEbus modules (e.g., I/O cards, memory modules). This ensures backward compatibility with legacy VME systems, protecting existing infrastructure investments in moderate-complexity setups.

Industrial-Grade Durability: Operating from -40°C to +85°C, the **Motorola MVME 162-23** withstands extreme temperatures, vibration, and electromagnetic interference (EMI) common in manufacturing plants, light industrial machinery, and remote control systems. Its rugged mechanical design and high-quality components ensure long-term stable operation, minimizing unplanned downtime.

Typical Application Scenarios

Mid-Scale Manufacturing Control: In packaging machinery lines, the **Motorola MVME 162-23** serves as the main controller for conveyor systems and packaging actuators. Its MC68030 processor runs sequential control software, while the RS-232C port connects to position sensors and basic HMI terminals. The Industry Pack port adds digital I/O for controlling solenoid valves, ensuring efficient and reliable packaging processes.

Industrial Equipment Retrofit: In retrofitting older textile or food processing machines, the **Motorola MVME 162-23** replaces obsolete 8-bit or 16-bit controllers while maintaining compatibility with existing sensors and small motor drives. Its parallel port connects to legacy printers for production batch logs, and the rugged design withstands the dusty, moderate-vibration environment of industrial facilities.

Remote Monitoring & Control: In legacy environmental monitoring stations (e.g., water treatment plants, weather stations), the **Motorola MVME 162-23** processes data from basic sensors (e.g., pH sensors, temperature probes) and transmits it to central systems via the RS-232C port. Its VMEbus interface integrates with simple data logging modules, and the watchdog timer ensures system stability in remote, unmanned locations.

Entry-Level Test & Measurement: In low-volume production test rigs or educational laboratories, the **Motorola MVME 162-23** controls basic data acquisition from sensors (e.g., pressure gauges, thermometers) and outputs test results to strip chart recorders via the parallel port. Its compatibility with legacy OS (e.g., OS-9) ensures continuity of simple test procedures developed over years.
