Xycom XVME-402 Overview
The Xycom XVME-402 is a Bitbus controller card based on the VME-bus architecture, primarily used to implement Bitbus (i80c152) bus bridging and management within VME systems.
Key Features
Bitbus Controller:
Equipped with the i80c152 processor, it provides a full implementation of the Bitbus protocol and enables data exchange between the VME-bus and external Bitbus devices.
VME-bus Interface:
Compliant with the IEEE 1014 VME standard, supporting A16/D08 (or wider) address/data buses. It can be installed directly into a 6U VME chassis.
Versatile Applications:
Commonly used in experimental devices, industrial automation, and large-scale research facilities as an I/O subnet controller.
Examples include:
- Serving as a Bitbus-to-VME bridge in the APS (Advanced Photon Source) control system
- Managing Bitbus control and signal distribution in the NA49 experiment’s TPC readout electronics
Power Requirements:
Operates on +5 V power, with a typical consumption of about 1 A (actual values vary slightly by configuration), fully compliant with VME-bus power specifications.
Mechanical Dimensions:
Single-width 6U (approx. 9.2″ × 6.3″), compatible with standard VME-bus backplanes.
Typical Use Cases
- Experimental Physics & Research Facilities:
Used as a Bitbus-to-VME bridge for high-speed digital I/O, pulse control, and similar tasks. - Industrial Automation:
Provides unified VME host management for Bitbus field devices in systems requiring Bitbus fieldbus networking. - Embedded Control Systems:
Works with VME-CPU boards (e.g., XVME-653/654) to build complete real-time control platforms.
Technical Overview
- Processor:
i80c152 Bitbus chip with integrated DMA and interrupt control. - Interfaces:
VME-bus master/slave modes; supports up to 3 Bitbus channels (expandable through external Bitbus I/O modules). - Software Support:
Offers Bitbus driver libraries and sample programs; compatible with real-time OS environments such as VxWorks and RTEMS, and also supported under MS-DOS BSP.
In summary, the Xycom XVME-402 is a dedicated Bitbus controller card designed for VME-based environments, well-suited for industrial and scientific applications that require Bitbus integration within a VME platform.
