Motorola MVME162PA-344E
Product introduction
The Motorola MVME162PA-344E is an enhanced rugged VMEbus SBC, purpose-built to address the demands of mid-to-high-performance industrial and aerospace control systems. As a premium variant of the MVME162 series, Motorola MVME162PA-344E builds on the base MVME162 platform’s reliability while boosting processing power, memory capacity, and I/O flexibility—making it a go-to solution for users needing to extend legacy VME systems without sacrificing modern functionality.
At its core, Motorola MVME162PA-344E features a 40 MHz MC68040 processor (faster than the 33 MHz variant in standard MVME162 models) and integrated FPU, enabling it to handle complex real-time tasks like PID control loops and sensor data aggregation with minimal latency. Its expanded memory—32 MB DRAM (upgradable to 128 MB) and 1 MB battery-backed SRAM—ensures it can run industrial operating systems (e.g., VxWorks, QNX) and preserve critical process data during power outages.
What sets Motorola MVME162PA-344E apart is its balance of legacy and modern connectivity: 4 configurable serial ports link to older sensors/actuators, 100Base-TX Ethernet connects to modern SCADA/MES systems, and SCSI-3 Ultra supports high-speed data storage. When paired with Motorola MVME705B (system controller) or IPMC7616E-002 (PMC I/O module), it becomes a fully scalable control node—ideal for aerospace test benches, oil rig control rooms, or railway signaling systems where downtime risks significant costs.
Core advantages and technical highlights
Enhanced Processing Power for Real-Time Tasks: The 40 MHz MC68040 in Motorola MVME162PA-344E delivers 21% faster instruction execution than standard 33 MHz MVME162 models. A chemical plant uses it to manage a batch reactor system, where the processor runs 12 concurrent PID loops (temperature, pressure, flow) with 2 ms update cycles. This speed improvement reduced batch cycle time by 18% (from 5 hours to 4.1 hours) and cut raw material waste by 12%, saving $45,000 annually.
Expanded Memory for Demanding Workloads: With 32 MB DRAM (upgradable to 128 MB), Motorola MVME162PA-344E outperforms lower-memory SBCs in data-intensive applications. An aerospace test lab deploys it to log 50 channels of engine test data (vibration, fuel flow) at 1 kHz sampling. The expanded DRAM stores 24 hours of raw data locally (vs. 8 hours on standard MVME162 models), eliminating the need for constant network transfers and reducing reliance on external storage—critical for remote test sites with limited connectivity.
Rugged Design for Harsh Environments: Class 3 conformal coating and -40°C to +75°C operating range make Motorola MVME162PA-344E suitable for extreme conditions. A railway operator uses it in track signaling systems, where the SBC withstands temperature swings from -35°C (winter) to +70°C (summer) and vibration from passing trains. Over 5 years, Motorola MVME162PA-344E units required zero replacements—whereas commercial-grade SBCs failed every 18 months, costing $30,000 per incident in signaling downtime.
Flexible I/O for Legacy-Modern Integration: 4 configurable serial ports (RS-232/422/485) and 100Base-TX Ethernet let Motorola MVME162PA-344E bridge old and new systems. A water utility uses it to upgrade a 20-year-old pump station: serial ports connect to legacy pressure sensors, Ethernet links to a cloud-based monitoring platform, and SCSI-3 Ultra archives 6 months of usage data. This upgrade avoided $200,000 in full system replacement and improved pump efficiency by 9%, reducing energy costs by $18,000 yearly.
Typical application scenarios
In aerospace ground test systems, a defense contractor uses Motorola MVME162PA-344E as the core controller for a missile guidance test bench. The SBC pairs with Motorola IPMC7616E-002 (PMC I/O module) to interface with 16 analog sensors (gyroscopes, accelerometers) and 8 digital actuators. Its 40 MHz processor processes sensor data in real time to simulate flight conditions, while 100Base-TX Ethernet streams test results to a central database.
Motorola MVME162PA-344E’s -40°C to +75°C tolerance works in climate-controlled test chambers, and its battery-backed SRAM preserves test parameters during power interruptions. Over 2 years, the system maintained 99.92% uptime, reducing test resets by 80% and accelerating missile certification by 3 months—saving the contractor $350,000 in labor and equipment costs.
In oil & gas, an offshore rig operator deploys Motorola MVME162PA-344E to control a subsea wellhead monitoring system. The SBC connects to 24 pressure/temperature sensors via RS-485 serial ports, processes data to detect leaks, and transmits alerts to the rig’s DCS via 100Base-TX Ethernet. Its Class 3 conformal coating resists saltwater corrosion, and its vibration tolerance (15 g) withstands rig movements. This setup reduced unplanned well shutdowns by 65%, avoiding $1.2 million in lost production annually.

Installation, commissioning and maintenance instructions
Before installing Motorola MVME162PA-344E, power off the VME chassis and wear an ESD wristband to prevent electrostatic damage. Verify the chassis supports VMEbus Rev D/VME64, provides +5V @3.0A and ±12V @0.5A, and has adequate cooling (minimum 20 CFM airflow). Gather tools: torque screwdriver (for chassis mounting), serial/Ethernet cables, multimeter (to check power rail voltages), and a VGA monitor (for initial configuration).
If using IndustryPack® or PMC modules (e.g., IPMC7616E-002), insert them into Motorola MVME162PA-344E’s slots first—align connectors carefully to avoid bending pins. Mount the SBC in the chassis, secure with screws torqued to 0.5 N·m, and connect peripherals: use shielded cables for serial/Ethernet runs over 10 meters, and ensure SCSI-3 cables are terminated properly. For commissioning, power on the chassis, access the boot utility via serial console (9600 baud, 8N1), and verify memory detection and interface functionality.
For maintenance, perform monthly inspections: check LED indicators (green = power, blinking amber = CPU activity, Ethernet link light = network connection), clean edge connectors with compressed air (15 PSI max), and test battery-backed SRAM by powering off for 10 minutes (critical data should remain intact). Replace the SRAM battery (3V lithium) annually. If serial communication fails, verify port configuration (baud rate, parity); if Ethernet drops, check cable continuity and IP settings. Keep a spare Motorola MVME162PA-344E with matching firmware to minimize downtime in critical applications.
