GE VME-PMC-CADDY 6U VMEbus Dual-Slot PMC Mezzanine Carrier Board

The GE Intelligent Platforms VME-PMC-CADDY is a versatile, high-reliability 6U VMEbus baseboard specifically architected to expand the lifecycle and processing capability of embedded real-time systems. By providing an optimized interface between standard PCI Mezzanine Cards (PMCs) and the standard VME architecture, this carrier card allows engineers to combine a variety of specialized communication, data acquisition, and graphics interfaces onto a single VME slot.

The heart of the design is a robust VME-to-PCI bridge controller (such as the Tundra Tsi148 or Universe series) alongside an onboard Freescale MPC8349 management microcontroller operating at 400 MHz. Backed by 128 MB of error-correcting DDR2 RAM and dedicated NOR flash memory, the system ensures seamless hardware initialization, robust diagnostics, and transparent data throughput across the legacy bus. The board supports 32/64-bit PCI signaling at up to 66 MHz, giving high-performance mezzanine modules full access to system assets. Rear I/O routing maps all PMC user I/O directly to the VME backplane via flexible pin assignments conforming to VITA standards, minimizing front-panel cabling layout and maximizing structural integrity in harsh deployment environments.

• High-Throughput PCI-to-VME Bridging: Powered by industrial-standard VME bridges supporting 2eVME and 2eSST fast protocols for maximum backplane data transfer rates.

• Dual-Slot Scalability: Seamlessly hosts either two single-width PMC modules or a single double-width mezzanine card to consolidate system functions.

• Flexible I/O Routing Schemes: Conforms fully to VITA 35 specifications, routing PMC I/O lines directly to the row connections of the VME P2 or P0 connectors.

• Onboard Power Isolation: Equipped with optional onboard 3.3V generation circuitry, reducing reliance on backplane constraints and preventing cross-module electrical noise.

• Ruggedized Options: Available in commercial air-cooled configurations as well as fully conduction-cooled, conformal-coated variations designed to survive sub-zero temperatures and high vibration profile.

• Defense & Aerospace Avionics: Flight control simulation, radar signal tracking, and localized telemetry decoding.

• Legacy System Upgrades: Retaining standard VME backplanes while introducing contemporary FPGA or network PMCs.

• Industrial Automation & Testbeds: High-speed data acquisition loops, factory PLC bridging, and deterministic HIL (Hardware-in-the-Loop) simulation.

• Transportation & Rail Systems: Trackside monitoring arrays, interlocking signal safety controls, and onboard telemetry processors.

Q1: Does the VME-PMC-CADDY carrier board support 5V PCI signaling modules?

A: No, the standard VME-PMC-CADDY/2 variants are explicitly designed for 3.3V PCI signaling levels to protect high-speed bus transceivers. Please ensure your targeted PMC cards are 3.3V tolerant or feature universal keying before slotting them into the board.

Q2: How is the user I/O on the mezzanine cards exposed to the wider system?

A: The carrier card leverages standard VITA 35 layout mappings. The user I/O pins from PMC Slot 1 are routed directly to the VME backplane P0/P2 connectors depending on your specific model subset, allowing a clean, cable-free connection to rear transition modules (RTMs).

Q3: What operating systems are natively supported by this carrier framework?

A: Because the VME-PMC-CADDY acts as a transparent hardware-level PCI bridge, it does not require specialized operating system drivers for basic operation. However, GE provides comprehensive VxWorks library packages (e.g., V.1915.58) to manage advanced configuration registers and microcontroller diagnostics.

Q4: Can I mix an XMC card and a PMC card simultaneously on this hardware?

A: Only if you are utilizing the specific hybrid model variant (such as the XMC-enabled option). Standard configurations support two standard PMCs. The hybrid version updates Slot 1 with a VITA 42.3 XMC connector while retaining a standard PMC setup on Slot 2.
