MOTOROLA MVME-167-01B

Product Introduction

The Motorola MVME-167-01B is a legacy entry-tier SBC from Motorola’s MVME-167 series, engineered to deliver essential data integrity and basic processing for ultra-budget mid-scale VMEbus-based automation systems. As a 3U VME device, it bridges the gap between basic controllers like the Motorola MVME-201 and value-tier models such as the Motorola MVME167-03B, offering ECC DRAM (a key upgrade from non-ECC entry controllers) and integrated connectivity—without the memory, I/O, or speed overhead of higher MVME-167 variants.

In automation architectures, the Motorola MVME-167-01B acts as a “budget-critical processing node”: its 16 MHz MC68040 processor handles light tasks (e.g., auxiliary equipment monitoring), 1 MB ECC DRAM protects essential data (e.g., simple sensor logs), and streamlined interfaces enable connectivity without extra hardware. For example, in a small municipal wastewater plant’s pump monitoring system, the Motorola MVME-167-01B can track 4 pump statuses (digital inputs), trigger alarm lights (digital outputs), log runtime to a SCSI drive, and send basic alerts to a local Ethernet HMI—all within its performance limits. Today, it remains a reliable choice for maintaining legacy systems in sectors like small-scale agriculture, auxiliary lab equipment, and low-volume manufacturing, where budget constraints demand stripped-back, essential functionality.

Core Advantages and Technical Highlights

Entry-Level ECC DRAM for Essential Data Protection: Unlike basic controllers (e.g., Motorola MVME-201) with no error correction, the Motorola MVME-167-01B includes 1 MB ECC DRAM that detects and fixes single-bit errors—critical for applications where even minor data corruption risks equipment damage. In a small greenhouse’s fan control system, this means the Motorola MVME-167-01B retains accurate temperature thresholds even in dusty environments, preventing fan failures that could kill crops. This feature reduces data-related downtime by 25% compared to non-ECC alternatives, while costing 30% less than the Motorola MVME167-03B.

Streamlined Connectivity for Low-Speed Tasks: The Motorola MVME-167-01B integrates only essential interfaces (1 serial, 1 Ethernet, 1 SCSI) and 8 digital I/O channels—avoiding the cost of unused ports. In a small university lab’s sample stirrer system, the Motorola MVME-167-01B uses its serial port to connect a speed sensor, digital outputs to control stirrer on/off, Ethernet to send daily run logs to a lab PC, and SCSI to store 1 month of data. The half-duplex Ethernet (low-bandwidth) and PIO-mode SCSI (2 MB/s) are perfectly sized for slow, intermittent data transfers, eliminating the expense of high-speed features in the Motorola MVME167-03B.

Ultra-Low Power for Compact, Battery-Powered Setups: The Motorola MVME-167-01B draws just 1.2 A typical at +5 VDC—25% less than the Motorola MVME167-03B—making it ideal for space-constrained, battery-powered systems (e.g., portable environmental sensors or remote pump monitors). In a mobile soil testing unit, the module’s low power draw extends battery life to 8+ hours during fieldwork, while its 3U form factor fits in a compact enclosure. This efficiency also cuts heat generation, removing the need for fans and extending component life by 4–6 years.

Typical Application Scenarios

The Motorola MVME-167-01B excels in ultra-budget, low-speed automation tasks. In a small-scale organic farm’s irrigation system (paired with Motorola MVME-050 for extra I/O), the Motorola MVME-167-01B manages 4 drip lines: its 4 digital inputs read soil moisture sensors, 4 digital outputs activate solenoid valves, 1 serial port connects to a rain gauge, and Ethernet sends weekly water usage to a farm laptop. The ECC DRAM ensures no valve settings are corrupted during power blips, while the 16 MHz processor handles simple “moisture low → valve on” logic without lag—preventing overwatering that wastes resources.

In a small electronics repair shop’s soldering station monitor, the Motorola MVME-167-01B tracks 4 station temperatures: digital inputs read thermocouple signals (via a converter), digital outputs trigger “overtemp” alarms, SCSI stores 2 weeks of temperature logs, and Ethernet sends alerts to a shop PC. The module’s 0°C–60°C operating range withstands the shop’s heat, while the battery-backed SRAM retains alarm thresholds during power outages. For the shop, the Motorola MVME-167-01B avoids the $20k cost of the Motorola MVME167-03B, as it meets basic monitoring needs while staying within a tight budget.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing Motorola MVME-167-01B, power off the VME chassis and verify compatibility with ±12 VDC (0.3 A max) and +5 VDC (1.6 A max) to prevent electrical damage. Use an anti-static wristband and mat to protect the processor and ECC DRAM from ESD. Gather tools: Phillips screwdriver (chassis mounting), Cat5 Ethernet cable (low-bandwidth rated), short SCSI-1 cable (4-foot max for PIO-mode signal integrity), torque wrench (0.4–0.6 N·m for terminals), and a serial terminal (for EEPROM configuration). Avoid installing near high-EMI sources (e.g., small heaters, power strips) to prevent Ethernet/SCSI signal corruption—critical for the module’s low-speed interfaces.

Maintenance suggestions: Monthly, inspect Motorola MVME-167-01B’s LEDs—steady green ECC “OK” LED confirms no errors; slow-blinking Ethernet LED indicates basic connectivity. Quarterly, clean the VME connector with compressed air (low pressure) to remove dust. Every 24 months, replace the TOD clock/SRAM backup battery (3V lithium) and run ECC self-tests via the serial terminal (use Motorola’s lightweight diagnostic firmware). If expanding memory, use only 32-bit ECC DRAM modules (1 MB–2 MB) to retain error protection. If SCSI transfers slow, check cable length (keep under 4 feet); if I/O channels fail, repurpose spare channels via EEPROM (e.g., use an unused input as an output). Store a backup EEPROM with system settings to minimize downtime during replacement.
