Motorola MVME5100 VMEbus Single-Board Computer (SBC)

Product Short Description

High – Performance Embedded Computing: The combination of PowerPC G3/G4 processors and a 100 MHz front – side bus, along with large ECC memory, enables it to handle complex control algorithms and data – intensive tasks in real time.
Robust Error Handling: ECC SDRAM detects and corrects single – bit errors and detects multi – bit errors. There is also a built – in watchdog timer and NVRAM – RTC to ensure system integrity and timekeeping in case of power outages.
Flexible Expansion: The 32/64 – bit PMC slot supports a wide range of I/O, communication and specialty modules. The dual Ethernet ports facilitate network redundancy and data logging.
VMEbus Optimization: The PowerPlus II architecture ensures full PCI throughput without affecting processor memory bandwidth, and it fully complies with VME64 for seamless integration into existing VME systems.
Industrial – Grade Durability: It can operate stably in harsh environments with wide temperature ranges, vibration and shock resistance, meeting the requirements of long – term deployment in industrial and military scenarios.
Legacy Software Support: The PPCBug firmware and PowerPC architecture support time – tested embedded operating systems and real – time kernels, protecting users’ software investment.
