VMIC+ASSY 11993R2 ASSY 11994R13 High-Performance VMIC VME/PCI Bridge and I/O Expansion Assembly

Product Name

VMIC+ASSY 11993R2 – VMIC VME-to-PCI Bridge/Main Board Assembly
ASSY 11994R13 – VMIC I/O Expansion / Rear-Transition Module Assembly

Product Description

The VMIC+ASSY 11993R2 is GE Fanuc / Abaco Systems’ flagship VMIC VME-to-PCI bridge board, engineered to deliver ultra-low-latency data transfer between legacy VME backplanes and high-speed PCI/PCI-X domains. When paired with the companion ASSY 11994R13 rear-transition I/O module, the pair forms a complete, hot-swappable, high-density I/O subsystem for mission-critical industrial, defense, and telemetry applications. The VMIC+ASSY 11993R2 integrates dual DMA engines, on-board SDRAM buffers, and an intelligent FIFO scheduler, while the ASSY 11994R13 brings out 64 single-ended or 32 differential digital lines, four RS-422/485 serial channels, and an auxiliary PMC site for customer-specific mezzanine cards. Both assemblies conform to VITA 1.1-1997 (VME64x) and ANSI/VITA 31.1 standards, ensuring seamless interoperability with third-party VME SBCs.

Advantages and Features

  1. Ultra-low latency DMA: VMIC+ASSY 11993R2’s dual-channel DMA engine cuts VME-to-PCI latency to < 2 µs, ideal for high-rate data logging or real-time control loops.
  2. Hot-swap ready: Both ASSY 11994R13 and main board support ANSI/VITA 46.11-compliant hot insertion, minimizing downtime in redundant architectures.
  3. Flexible RTM I/O: ASSY 11994R13’s 64-bit DIO can be software-configured as input, output, or bi-directional with per-line change-of-state interrupt.
  4. Robust design: Conformal-coated ASICs, latching ejector handles, and wedge locks ensure survival in high-shock rail or airborne environments.
  5. Long-term support: GE/Abaco guarantees 15-year component availability for VMIC+ASSY 11993R2 and ASSY 11994R13, critical for defense programs.

Application Areas and Use-Cases

• Defense/Aerospace: On-board mission computers, radar data concentrators, electronic warfare (EW) recorders.
• Industrial Test & Measurement: Semiconductor burn-in chambers, multi-channel data acquisition (DAQ) systems.
• Transportation: Wayside signaling, rolling-stock traction control, high-speed train event recorders.
• Energy: Sub-surface seismic data loggers, wind-turbine condition monitoring.
Example case: A European defense integrator deployed VMIC+ASSY 11993R2 with ASSY 11994R13 in a VME64x chassis to aggregate 32 high-speed ADC channels at 20 MS/s, streaming data over PCI-X to a GPU card for real-time threat analysis. The solution achieved < 5 % CPU load on the VME SBC and passed MIL-STD-461E EMI requirements.

Selection Guidelines

• Choose VMIC+ASSY 11993R2 if you need the highest sustained VME-to-PCI throughput and ECC-protected buffering.
• Add ASSY 11994R13 when your application demands high-density digital I/O or serial interfaces without consuming additional VME slots.
• For air-cooled lab environments, select the standard heatsink; for conduction-cooled systems specify “-CC” option.
• Ensure your VME chassis supports 64-bit backplane and +5 V/3.3 V power rails; older 32-bit backplanes will throttle bandwidth to ~80 MB/s.

Precautions and Notes

  1. Firmware compatibility: Always flash both VMIC+ASSY 11993R2 and ASSY 11994R13 to the same firmware revision pair (e.g., 3.6.x). Mismatched revisions can cause RTM ID PROM read errors.
  2. PMC power budget: The PMC site on ASSY 11994R13 supplies 15 W; verify mezzanine card power draw before installation.
  3. VME slot spacing: Leave at least one empty slot adjacent to the main board when using high-power PMC cards for airflow.
  4. ESD handling: Both assemblies are Class 0 ESD sensitive; use wrist straps and conductive foam during integration.
