VME (VMEbus) is a high-performance computer bus standard originally developed by Motorola for use in industrial computers and embedded systems. It is a modular system that allows for a wide variety of boards to be plugged into a backplane, providing a flexible and scalable solution for a wide range of applications.

Parameters:

• Form factor: VMEbus
• Bus width: 32-bit or 64-bit
• Data transfer rate: Up to 400 MB/s
• Backplane slots: Up to 21
• Board types: CPUs, memory boards, I/O boards, graphics boards, etc.

Specifications:

• Mechanical: Size, weight, power requirements, etc.
• Electrical: Bus signals, timings, voltages, etc.
• Software: Operating systems, device drivers, etc.

Dimensions:

• VMEbus Single-Height (SH): 233 x 120 mm (9.17 x 4.72 inches)
• VMEbus Double-Height (DH): 233 x 240 mm (9.17 x 9.45 inches)
• VMEbus Full-Height (FH): 466 x 240 mm (18.35 x 9.45 inches)

Weight:

• VMEbus Single-Height (SH): Typically less than 1 pound (0.45 kg)
• VMEbus Double-Height (DH): Typically less than 2 pounds (0.91 kg)
• VMEbus Full-Height (FH): Typically less than 4 pounds (1.81 kg)

Series:

There are many different VME series, each with its own specific features and capabilities. Some of the most common VME series include:

• VMEbus Classic: The original VMEbus standard, introduced in 1982.
• VMEbus Extended: An extension of the VMEbus Classic standard, introduced in 1990.
• VME64: A 64-bit version of the VMEbus standard, introduced in 1995.
• VMEbus System Timing and Control (VSTC): A specification for synchronizing multiple VMEbus systems, introduced in 1998.

Features:

• Modular: Allows for a wide variety of boards to be plugged into a backplane.
• Scalable: Can be expanded to accommodate new requirements.
• High-performance: Supports high-speed data transfer rates.
• Rugged: Designed for use in harsh environments.

Applications:

VME products are used in a wide variety of applications, including:

• Industrial automation: Controlling machinery, robots, and other industrial equipment.
• Defense and aerospace: Avionics, radar, and other military systems.
• Medical imaging: X-ray, MRI, and other medical imaging systems.
