Motorola MVME-162-532A

Product Introduction

The Motorola MVME-162-532A is a legacy industrial VMEbus mid-tier real-time SBC designed to balance processing power and expandability for 1990s–2000s-era automation systems. Unlike entry-level SBCs like Motorola MVME-147-011, Motorola MVME-162-532A integrates a MC68040 processor with FPU—enabling precise mathematical operations for tasks like closed-loop process control—while its 4 Industry Pack® ports support customizable I/O for analog sensors, digital actuators, or specialized communication modules.

As a workhorse in Motorola’s VME lineup, Motorola MVME-162-532A acts as a “flexible control hub” for industrial systems. It connects to peripheral modules (e.g., Motorola IP-320 for analog data) via Industry Pack ports and communicates with central controllers via Ethernet or serial links. For example, in a 1990s automotive assembly line, Motorola MVME-162-532A processed robotic arm position data (via FPU) and coordinated with conveyor controllers—its battery-backed SRAM ensuring critical calibration data survived power outages. Today, it remains vital for legacy systems where replacement would require costly rewiring of Industry Pack-based I/O.

Core Advantages and Technical Highlights

FPU-Powered Precision for Complex Calculations: The MC68040’s integrated FPU in Motorola MVME-162-532A delivers 5x faster floating-point performance than FPU-less SBCs like Motorola MVME-147-011. In a chemical plant’s pH control system, Motorola MVME-162-532A uses the FPU to calculate dosage adjustments (±0.01 pH accuracy) based on sensor data—avoiding chemical waste and ensuring compliance with process standards. This precision made it a top choice for applications where rounding errors would compromise quality or safety.

Industry Pack Expansion for Customizable I/O: With 4 Industry Pack® ports (each with dedicated DMA), Motorola MVME-162-532A adapts to diverse tasks without replacing the entire SBC. A water treatment plant added Motorola IP-320 (analog I/O) and Motorola IP-485 (RS-485) modules to Motorola MVME-162-532A—monitoring turbidity (analog) and controlling pumps (digital) via one SBC. This flexibility reduced chassis slot usage by 60% vs. using separate I/O modules, cutting hardware costs and simplifying maintenance.

Reliable Data Integrity Features: Motorola MVME-162-532A’s programmable DRAM parity and battery-backed SRAM protect against data loss in harsh environments. In a power substation, DRAM parity detected and corrected single-bit errors from electrical interference—preventing incorrect load calculations that could trigger equipment shutdowns. The 512 KB SRAM preserved substation configuration data during power outages, enabling instant system recovery without manual reconfiguration.

Typical Application Scenarios

In a 1990s-era paper mill, Motorola MVME-162-532A controlled the paper rolling process—paired with Motorola IP-320 (analog I/O) to monitor roll tension (4–20mA) and Motorola MVME341A (serial module) to send production data to a central SCADA system. The MC68040’s FPU calculated tension adjustments in real time (±0.1 N accuracy), ensuring uniform paper thickness. Its -20°C–65°C operating range withstood the mill’s hot, humid environment, while Industry Pack expansion let the mill add a temperature monitoring module later—avoiding a full SBC upgrade.

For a regional wastewater treatment plant, Motorola MVME-162-532A managed 8 aeration tanks. It used 2 Industry Pack analog modules to measure dissolved oxygen (0–10V) and 2 digital modules to control air blowers. The battery-backed SRAM stored blower runtime logs during power outages, and the optional Ethernet port sent daily water quality reports to a county server. Motorola MVME-162-532A’s reliability kept the plant compliant with EPA regulations for over 15 years, with minimal unplanned downtime.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing Motorola MVME-162-532A, verify the VME chassis supports double-high 6U modules and A32/D64 addressing. Confirm the power supply provides +5V DC (±5%) and +12V DC (±10%) – use a multimeter to check for ripple (<50mV) that degrades DRAM parity. Gather tools: anti-static wristband (protects MC68040), torque screwdriver (0.5 N·m for 6U mounting), and Industry Pack alignment tool (to avoid damaging ports). If adding Ethernet, ensure the transceiver is compatible with 32-bit DMA; label Industry Pack cables by port to simplify troubleshooting.

Maintenance suggestions: For daily upkeep, check Motorola MVME-162-532A’s LEDs – steady power, blinking processor activity, and no parity fault lights indicate normal operation. Test DRAM parity monthly via the host OS; replace DRAM if multi-bit errors occur. Clean the module’s vents quarterly with compressed air (20 PSI max) to prevent overheating. Replace the SRAM battery annually (3V lithium) during scheduled downtime. Store spare Motorola MVME-162-532A units in anti-static bags (15°C–25°C, 40%–60% humidity) to preserve the MC68040 and flash memory.
