Real-World Use & Application Scenarios
The Motorola MVME5100 series is a robust and high-performance VMEbus single board computer family tailored for critical industrial, defense, aerospace, and medical imaging applications. It is commonly deployed in control systems that demand real-time processing, high-speed data acquisition, and fault-tolerant operation within rugged environments. The series is designed to support demanding control room automation, signal processing, and communication functions, ensuring continuous operation in environments characterized by vibration, temperature extremes, and electromagnetic disturbances. The MVME5100 is ideal for engineers and system integrators seeking reliable, scalable computing power that integrates seamlessly into legacy VMEbus infrastructures.
Product Introduction & Positioning
The Motorola MVME5100 is based on the PowerPC MPC750 class processor running at 450 MHz with 32 KB each of instruction and data L1 cache and a substantial 1 MB L2 secondary cache. This significant processing capability supports intensive applications requiring fast execution of control and data acquisition tasks. The module offers up to 512 MB of PC100 ECC SDRAM onboard, expandable to 1 GB using RAM500 memory mezzanine modules, with 17 MB of flash memory for boot and application storage. Two front-panel IEEE P1386.1 PCI Mezzanine Card (PMC) slots allow flexible I/O expansion.
Its VMEbus interface utilizes the Tundra Universe chip with 2eSST support, offering a wide VME address range, 64-bit data access, and burst transfer capabilities to ensure high data throughput. Multiple communication interfaces including dual 10/100Base-T Ethernet ports, dual asynchronous serial ports, and a 32 KB battery-backed non-volatile RAM with real-time clock further enhance its connectivity and operational reliability.
Key Technical Features & Functional Benefits
The MVME5100 balances speed and durability with 450 MHz PowerPC processor power backing its real-time control capabilities, coupled with multi-level caching for improved performance. Its memory system supports ECC SDRAM with fast PC100 bus speeds enhancing data reliability in noisy industrial environments. Expandable memory through RAM500 mezzanine modules increases flexibility, allowing for tailored system configurations.
Equipped with dual PMC slots, the MVME5100 supports a wide range of PCI-based I/O modules enabling customization for various industrial interface requirements. Dual Ethernet ports facilitate robust network communication essential for distributed control systems. Its onboard watchdog timer, multiple 32-bit timers, and 16C550 compatible serial ports ensure dependable system monitoring and interface versatility.
Designed for rugged environments, the MVME5100 is built to meet MIL-STD-810 shock and vibration standards, has conformal coating for moisture resistance, and complies with electromagnetic compatibility regulations (FCC, CE). The firmware monitor built-in supports diagnostics, testing, and boot operations, streamlining development and maintenance efforts.
