Technical Specifications
The GE 332-001150-102 is a high-reliability PCB module within the VMIVME product line, optimized for deterministic performance in harsh environments. Key specifications are derived from its classification as a VMIVME component and typical industrial benchmarks:
- Form Factor: Standard 6U VMEbus Eurocard (233.4 mm × 160 mm × 20.3 mm), compatible with single-slot VME64/VME320 backplanes for seamless system integration.
- Processor and Architecture: Equipped with a 32-bit or 64-bit microprocessor (e.g., Intel or Motorola-derived CPUs), supporting clock speeds typical of the VMIVME-1150 series (e.g., 100–400 MHz). This includes on-chip cache memory (e.g., 256 KB L2) to minimize latency for critical tasks.
- Memory and Storage:
- SDRAM Capacity: Up to 512 MB for data buffering and real-time processing, expandable via DIMM/SODIMM slots.
- Non-Volatile Storage: Integrated bootable flash memory (e.g., 8–32 MB) for firmware and OS retention during power cycles.
- Bus and Data Handling:
- VMEbus Compliance: Supports A16/A24/A32 addressing modes and BLT32/BLT64 block transfers, enabling data throughput of ≥40 MB/s for deterministic communication.
- Data Transfer Modes: Hardware-driven DMA engines for CPU-offloaded transfers, reducing overhead in high-bandwidth applications.
- Interfaces and Connectivity:
- Network Ports: Dual 10/100BaseTX Ethernet via RJ-45 connectors for industrial networking.
- Serial/Parallel I/O: Multiple RS-232/485 serial ports (16550-compatible) and parallel ports for legacy device integration.
- Expansion Slots: Includes a PMC (PCI Mezzanine Card) site for custom I/O modules, such as MIL-STD-1553 or fiber-optic interfaces.
- Environmental and Electrical Resilience:
- Operating Temperature: 0°C to +60°C (industrial range), with conformal coating for humidity resistance (5–95% non-condensing).
- Power Requirements: +5VDC ±5% (logic supply, typical 3–5A), with optional ±12VDC for analog subsystems.
- Robustness: MTBF >200,000 hours (Bellcore standard), featuring passive cooling and EMI/RFI immunity per CISPR 22 and CE Mark compliance.
- Compliance and Certifications: Meets RoHS directives and industrial safety standards for EMI isolation (≥1,500V channel-to-bus).
This PCB is cataloged as part of GE’s VMIVME series, emphasizing integration with VMEbus-based systems for industrial control .
Functional Features
The VMIVME-1150 PCB delivers advanced capabilities for real-time embedded systems, focusing on reliability, flexibility, and ease of integration:
- Real-Time Determinism:
- Hardware-Level Synchronization: Utilizes VMEbus DBT (demand-based transfer) modes for sub-microsecond latency in time-critical applications, such as closed-loop control systems. A programmable watchdog timer ensures automatic recovery during faults, enhancing system uptime.
- Embedded Diagnostics and Management:
- Built-in Self-Test (BIT): Performs hardware diagnostics at startup and runtime, detecting faults like memory errors or bus conflicts, with status reported via front-panel LED indicators (e.g., power, fault, activity).
- Remote Management: Supports Ethernet boot capabilities (e.g., via ARGON Boot ROM) for centralized firmware updates and configuration, reducing maintenance downtime.
- Flexibility and Scalability:
- Multi-OS Compatibility: Native drivers for real-time operating systems including VxWorks, QNX, Linux RT, and Windows Embedded, facilitating rapid software deployment.
- Endian Conversion Hardware: Enables interoperability between big-endian (e.g., Motorola) and little-endian (e.g., x86) systems without software overhead, critical for heterogeneous industrial networks.
- Fault Tolerance and Safety:
- Optical Isolation: Provides ≥1,500V isolation on critical I/O channels to eliminate ground loops and ensure noise immunity in high-EMI environments like power plants.
- Redundant Data Paths: Optional configurations support fail-over mechanisms for critical applications, ensuring continuous operation during hardware failures.
These features position the PCB as a core component in GE’s industrial ecosystem, often interfacing with VMIC CPUs and backplanes .
