Description

Motorola MVME51105E-2261 Single Board Computer Specification

Product Overview

The ​Motorola MVME51105E-2261 is a high-performance ​VMEbus single-board computer (SBC) engineered for mission-critical embedded applications in industrial automation, defense, and telecommunications. As part of the legacy ​MVME5100 series, this ruggedized board delivers deterministic computing power with extended environmental tolerance (-40°C to +85°C). Built around a PowerPC™ processor with extensive I/O capabilities, the ​Motorola MVME51105E-2261 executes real-time control algorithms for robotics, signal processing, and system monitoring. Its modular architecture supports complex applications in particle accelerators, radar systems, and automated test equipment while maintaining backward compatibility with legacy VME systems.

Key Functional Capabilities

Deterministic Real-Time Computing:
500 MHz PowerPC™ MPC7410 with AltiVec™ SIMD engine processes PID control loops and FFT algorithms with ≤5 µs jitter, essential for beamline control in synchrotrons and servo positioning systems.

Extreme Environment Resilience:
Conduction-cooled design eliminates fans, preventing dust ingress in cement plants and metal foundries. Validated for 15g vibration (IEC 60068-2-64) and thermal cycling from -40°C to +85°C.

MVME5100

Hybrid Legacy-Modern Integration:
Backward compatibility with ​MVME2700-era VME chassis while supporting modern protocols:

  • PMC slots host ​MVME5500-0161 analog I/O or ​Kontron Pyxis™ GPGPU cards
  • Dual Gigabit Ethernet enables IEEE 1588 PTP time synchronization
  • VME64 to PCI-X bridge (Tsi148 chip) sustains 160 MB/s throughput

Robust Security Architecture:
Hardware-enforced secure boot with FPGA-based watchdog timer. Supports encrypted OS kernels (VxWorks®/Linux RT) meeting MILS separation requirements for defense applications.

Extended Diagnostic Intelligence:
Built-In Test (BIT) at power-up verifies CPU/RAM/FPGA integrity. Front-panel LEDs report voltage, temperature, and network status. SNMP traps forward faults to centralized monitoring.

Targeted Application Domains

Defense Systems:

  • Radar signal processing (Doppler filtering/beamforming)
  • UAV flight control with encrypted datalink interfaces
    Industrial Automation:
  • 6-axis robotics motion planning and collision avoidance
  • Power plant turbine control coordination (via Modbus/TCP)
    Telecom Infrastructure:
  • Baseband processing in 4G/LTE base stations
  • Optical transport network timing controllers
    Scientific Research:
  • Particle accelerator beam diagnostics (CERN LHC)
  • Radio telescope correlator subsystems
    Transportation:
  • Railway signaling control (SIL 2 via redundancy)
  • Airport baggage handling system sorting logic
