The Motorola MVME162-013 represents the radiation-hardened variant of Motorola’s battle-proven VMEbus computing platform, specifically engineered for nuclear power instrumentation and space satellite control systems. This 64-bit embedded controller features dual PowerPC 750FX processors clocked at 800MHz with 256KB L2 cache per core, delivering 2400 MIPS performance for real-time neutron flux monitoring in reactor containments. The MVME162-013 incorporates 512MB radiation-tolerant SDRAM with single-event upset (SEU) protection, maintaining data integrity in high-radiation environments like particle accelerator controls.
As part of the MVME160 Extreme Environment Series, this model introduces triple modular redundancy (TMR) voting logic for safety-critical applications in nuclear reprocessing plants. Its extended -55°C to +125°C operational range with 100G shock resistance meets MIL-STD-883J standards for military field deployment. The MVME162-013 supports SpaceWire interfaces through its PMC expansion sites, enabling seamless integration with satellite attitude control systems.

Key Features and Advantages:
Radiation resilience: The MVME162-013 employs silicon-on-insulator (SOI) technology and error-correcting memory architecture, reducing soft error rates by 99.7% compared to commercial controllers. This makes it indispensable for spent fuel pool monitoring systems.
High-speed data handling: Dual 800MHz processors with AltiVec vector processing units achieve 12.8GFLOPS performance for hyperspectral imaging in Earth observation satellites. The integrated SpaceWire interfaces support CCSDS packet telemetry standards.
Mission-critical redundancy: Triple voting logic compares outputs from dual processor channels, automatically switching to backup FPGA-based control in <10μs during SEU events. Front-panel fiber optic ports enable radiation-immune communication in nuclear reactor vessels.
Application Areas:
The Motorola MVME162-013 excels in:
- Nuclear Energy: Reactor core cooling pump control
- Space Systems: Satellite star tracker processing
- Medical: Proton therapy beam steering
- Defense: Nuclear submarine reactor monitoring
In uranium enrichment facilities, this controller manages 2,048 analog inputs for cascade pressure regulation. Space launch vehicles utilize its radiation-hardened design for telemetry processing during atmospheric re-entry.

Installation and Maintenance:
Installation preparation: Prior to installing the MVME162-013, verify VME64x backplane compliance and ensure proper grounding for EMI-sensitive environments. Use anti-static matting and ionized air blowers during handling to prevent charge accumulation on radiation-hardened components.
Maintenance recommendations: Conduct quarterly memory scrubbing using Motorola’s SEU Diagnostic Suite. Replace radiation-sensitive components (cooling fans, batteries) every 5 years regardless of usage. Perform TMR logic validation before annual reactor refueling cycles.
