Abaco Systems / VMIC VMIVME-7452-405 Single Slot VME Floppy/Hard Disk Module

The Abaco Systems / VMIC VMIVME-7452-405 is a single-slot VME 6U passive module that integrates floppy and hard disk storage into VMEbus systems. It connects to PC/AT Single Board Computer (SBC) IDE controllers through VME P2 user-defined pins, supporting 3.5-inch 1.44 MB floppy drives, hard disk drives, and optional Flash memory. The module operates at +5 V with maximum spin-up current of 2.5 A (typical <1.0 A) and includes both 34-pin floppy and 40-pin IDE connectors.

Technical Specifications

• Flash Drive Response Times: 2.5 ms sleep-to-write, 2.0 ms sleep-to-read, 50 ms typical reset-to-ready


• Flash Power Consumption (Sleep): 200 µA at 3.3 V, 500 µA at 5.0 V


• Flash Power Consumption (Read/Write): 32–80 mA at 3.3 V, 46–120 mA at 5.0 V

Key Features

• Passive VMEbus interface requires no active control logic


• Supports floppy, IDE hard disk, and Flash memory in single form factor


• Low standby power consumption for extended operation


• Dual connector options (34-pin floppy, 40-pin IDE) for flexible drive integration

Typical Applications

• VMEbus embedded systems requiring persistent storage


• Industrial and military platforms with rotating or solid-state storage needs


• Systems utilizing VMIC VMEbus CPU boards with integrated IDE controllers

Compatibility & Integration Designed for VMIC VMEbus-compatible PC/AT CPU boards including VMIVME-7589 and VMIVME-7587/VMIPMC-5588 combinations. Connects via VMXC-3 cable assemblies; use 14-inch VMXC-H cable for non-adjacent processor modules or double-slot configurations. Pairs with VMIPMC-5588 Reflective Memory board. Critical: Do not power module without CPU board connection to prevent hard disk configuration loss.
