Motorola MVME-162-532A

Product Introduction

The Motorola MVME-162-532 is a legacy industrial VMEbus entry-level mid-tier real-time SBC designed to deliver core processing functionality at a lower cost—serving as the foundational variant of the more feature-rich Motorola MVME-162-532A. Unlike its upgraded sibling (which adds FPU, DRAM parity, and Ethernet), Motorola MVME-162-532 retains the MC68040 processor’s core performance but streamlines non-essential features—making it ideal for 1990s-era automation tasks where complex calculations (e.g., closed-loop pH control) are not required.

As a cost-efficient solution in Motorola’s VME lineup, Motorola MVME-162-532 acts as a “basic control hub” for industrial systems. It connects to simple peripheral modules (e.g., Motorola IP-310 for basic analog I/O) via 2 Industry Pack ports and communicates with local controllers via serial links. For example, in a 1990s small-scale packaging plant, Motorola MVME-162-532 monitored conveyor belt sensors (via serial ports) and activated sorting actuators—its battery-backed SRAM ensuring production counts survived power outages. Today, it remains critical for legacy systems where upgrading to Motorola MVME-162-532A would be unnecessary and cost-prohibitive.

Core Advantages and Technical Highlights

Cost-Efficient Core Processing: Motorola MVME-162-532 delivers 70% of Motorola MVME-162-532A’s processing power at 50% of the cost, making it ideal for budget-constrained users. A 1990s food canning plant used Motorola MVME-162-532 to control can labeling machines—processing sensor data (e.g., “can present” signals) and triggering label applicators without needing a FPU. This avoided the $1,200+ premium for Motorola MVME-162-532A’s unused floating-point capabilities, while the MC68040’s MMU still ensured stable memory management for daily operations.

Simplified Expansion for Basic I/O Needs: With 2 16-bit Industry Pack ports, Motorola MVME-162-532 supports essential I/O without the complexity of DMA or 32-bit expansion. A rural water pump station added Motorola IP-310 (8-channel analog input) to Motorola MVME-162-532—monitoring 4 pump pressure sensors (0–10V) and sending alerts via serial ports if pressure dropped. This setup used 50% fewer chassis slots than discrete I/O modules, cutting hardware costs and reducing wiring time by 40%—critical for remote sites with limited maintenance resources.

Reliable Operation for Mild Environments: Motorola MVME-162-532’s 0°C–60°C operating range and 40 g shock resistance meet the needs of indoor industrial settings (e.g., factory floors, warehouse control rooms) where extreme temperatures are rare. In a 1990s electronics assembly workshop, Motorola MVME-162-532 operated reliably for 12+ years in controlled 20°C–25°C conditions, managing PCB inspection sensor data without overheating or vibration-related failures. Its simplified design also meant fewer components to fail, reducing unplanned downtime by 30% vs. more complex SBCs.

Typical Application Scenarios

In a 1990s small-scale textile mill, Motorola MVME-162-532 controlled yarn winding machines—paired with Motorola IP-310 (basic analog I/O) to monitor thread tension (4–20mA) and Motorola MVME-340B (serial module) to log production yards to a local printer. Without needing a FPU, the MC68040 processor still handled tension threshold checks (e.g., “stop if tension > 5 N”) in real time, ensuring consistent yarn quality. Its 0°C–60°C operating range withstood the mill’s warm (30°C–35°C) environment, while the 256 KB SRAM preserved daily production logs during power outages.

For a 1990s regional grocery distribution center, Motorola MVME-162-532 managed 6 walk-in cooler temperature sensors. It used 1 Industry Pack analog module to read temperature data (0–5V) and 1 digital module to activate alarm buzzers if temperatures exceeded 5°C. The serial port sent weekly temperature reports to a store manager’s computer, and the battery-backed SRAM stored alert logs for audit. Motorola MVME-162-532’s reliability kept food safe for over a decade, with no unplanned downtime—proving its value for low-complexity, high-criticality tasks.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing Motorola MVME-162-532, verify the VME chassis supports double-high 6U modules and A32/D32 addressing. Confirm the power supply provides +5V DC (±5%) and +12V DC (±10%) – use a multimeter to check for ripple (<100mV, as DRAM lacks parity to correct errors). Gather tools: anti-static wristband (protects the MC68040), torque screwdriver (0.5 N·m for 6U mounting), and Industry Pack alignment tool (to avoid damaging ports). Ensure connected Industry Pack modules are 16-bit (e.g., Motorola IP-310); 32-bit modules will not function with Motorola MVME-162-532.

Maintenance suggestions: For daily upkeep, check Motorola MVME-162-532’s LEDs – steady power and blinking processor activity indicate normal operation. Test DRAM monthly via the host OS (look for uncorrectable errors, as there is no parity); replace DRAM if errors occur. Clean the module’s vents quarterly with compressed air (15 PSI max) to prevent overheating in warm environments. Replace the SRAM battery annually (3V lithium) during scheduled downtime. Store spare Motorola MVME-162-532 units in anti-static bags (15°C–25°C, 40%–60% humidity) to preserve the MC68040 and EPROM.
