MOTOROLA MVME-167-32B
Product Introduction
The Motorola MVME-167-04B is a legacy mid-tier SBC from Motorola’s MVME-167 series, engineered to deliver balanced performance and cost-efficiency for mid-scale VMEbus-based automation systems. As a 3U VME device, it bridges the gap between entry-level SBCs like the Motorola MVME712-101 and high-memory models such as the Motorola MVME-167-32B, offering ECC DRAM (critical for data integrity) and integrated I/O—without the 32 MB memory overhead of its higher-end sibling.
In automation architectures, the Motorola MVME-167-04B acts as a “right-sized processing node”: its 25 MHz MC68040 processor handles moderate computational tasks (e.g., basic PID control), 4 MB ECC DRAM ensures error-free data storage for daily operations, and integrated serial/Ethernet/SCSI enable seamless connectivity. For example, in a regional food processing plant, the Motorola MVME-167-04B can monitor 6 mixing tanks (via serial sensors), log batch data to a SCSI drive, and send production status to a plant HMI via Ethernet—all without performance bottlenecks. Today, it remains a practical choice for maintaining legacy systems in sectors like beverage manufacturing, municipal water treatment, and small-scale semiconductor testing, where overinvesting in high-memory SBCs is unnecessary.
Core Advantages and Technical Highlights
Cost-Effective ECC DRAM for Critical Data: Unlike entry-level SBCs (e.g., Motorola MVME712-101) with non-ECC memory, the Motorola MVME-167-04B includes 4 MB ECC DRAM—correcting single-bit errors and detecting multi-bit errors—to protect critical data like recipe parameters or sensor logs. In a beverage bottling plant, this means the Motorola MVME-167-04B retains accurate fill-volume settings even in dusty, vibration-prone environments, preventing product waste due to data corruption. This feature reduces data-related downtime by 35% compared to non-ECC alternatives, while costing 40% less than the 32 MB Motorola MVME-167-32B.
Expandable Memory for Growing Needs: The Motorola MVME-167-04B’s DRAM (4–8 MB) is expandable—unlike the fixed 32 MB of the Motorola MVME-167-32B—letting users scale memory as their system evolves. For a small pharmaceutical lab starting with 2 bioreactors, 4 MB suffices to store sensor data and control logic; if the lab adds 2 more reactors later, upgrading to 8 MB (via industry-standard DRAM modules) avoids replacing the entire SBC. This scalability cuts long-term costs by 25%, as users only pay for the memory they need upfront.
Integrated I/O for Simplified Wiring: The Motorola MVME-167-04B integrates 16 digital I/O channels, 2 serial ports, Ethernet, and SCSI-1 in one slot—eliminating the need for 2–3 add-on modules. In a municipal wastewater pump station, this means the Motorola MVME-167-04B can control 8 pump relays (digital outputs), monitor 8 pressure sensors (digital inputs), connect to a remote SCADA system (Ethernet), and store pump runtime logs (SCSI)—all with a single module. This integration reduces chassis slot usage by 50% and simplifies troubleshooting, as all critical interfaces are centralized.
Typical Application Scenarios
The Motorola MVME-167-04B excels in cost-sensitive, mid-scale automation tasks. In a regional brewery’s fermentation control system (paired with Motorola MVME-705-1 for extra serial ports), the Motorola MVME-167-04B manages 4 fermentation tanks: its ECC DRAM stores temperature/PH setpoints, 25 MHz processor runs basic PID algorithms to adjust cooling, 16 digital I/O channels control tank valves, and Ethernet sends daily yield data to the brewery’s ERP system. The module’s 0°C–60°C operating range withstands the brewery’s cool ambient conditions, while ECC DRAM resists EMI from nearby compressors—preventing fermentation errors that would ruin batches.
In a small semiconductor testing lab, the Motorola MVME-167-04B controls a basic wafer probe station: serial ports connect to 4 test sensors (measuring voltage/current), SCSI stores test results for 100+ wafers per day, and digital I/O channels activate probe positioning motors. The expandable DRAM lets the lab upgrade from 4 MB (for small batches) to 8 MB (for high-volume testing) without replacing the SBC. For the lab, the Motorola MVME-167-04B avoids the $50k cost of the Motorola MVME-167-32B, as it meets testing requirements while staying within budget.

Installation, Commissioning and Maintenance Instructions
Installation preparation: Before installing Motorola MVME-167-04B, power off the VME chassis and verify compatibility with ±12 VDC (0.5 A max) and +5 VDC (2.4 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, terminated SCSI-1 cable, torque wrench (0.5–0.8 N·m for terminals), and a serial terminal (for EEPROM configuration). Avoid installing near high-EMI sources (e.g., variable-frequency drives, high-voltage lines) to prevent Ethernet/SCSI signal interference.
Maintenance suggestions: Monthly, inspect Motorola MVME-167-04B’s LEDs—steady green ECC “OK” LED confirms no memory errors; blinking Ethernet “activity” LED indicates data transfer. Quarterly, clean the VME connector with compressed air (low pressure) to remove dust. Every 2 years, replace the TOD clock/SRAM backup battery (3V lithium) and run ECC DRAM self-tests via diagnostic firmware. If expanding memory, use only ECC-compliant DRAM modules to maintain data integrity. If SCSI transfers slow, check cable termination (120Ω at end devices); if I/O channels fail, use the on-board debugger to isolate faults. Store a backup EEPROM with system configurations to minimize downtime during replacement.
