Product Details

The XYCOM XVME-660, PN 70660-716, is a discontinued dual-slot 6U VMEbus high-performance PC-compatible single board computer, designed for XYCOM legacy VME control racks and high-demand embedded industrial computing systems. It is equipped with Intel Celeron 566MHz or Pentium III 600MHz/700MHz processors, supporting MMX instruction set, and can run Windows, DOS, VRTX, UNIX and other PC or real-time operating systems. Onboard 64MB SDRAM, expandable up to 128MB for data buffering and multitask execution. This SBC adopts VME64x architecture and supports VME bus master and slave operation, A16/A24/A32 addressing modes, full 7-level VME interrupt and bus arbitration, able to coordinate analog acquisition, digital I/O, counter and communication modules on the VME backplane.

It integrates rich onboard peripheral resources. It carries 10/100Mbps Ethernet for network data transmission, Ultra SCSI and EIDE interfaces for storage access, two RS232 serial ports, one EPP/ECP parallel port, USB port, PS/2 keyboard and mouse interface. It reserves one PMC expansion slot, which can be fitted with PMC mezzanine cards to add custom communication, I/O or high-speed acquisition functions, greatly improving hardware flexibility. The onboard PCI bridge connects the local PC peripheral bus to the VME bus, realizing efficient data exchange between the x86 processor and VME field modules.

Users can configure VME base address, interrupt mapping, memory allocation and peripheral parameters through BIOS setup and on-board jumpers to avoid resource conflicts with other VME modules. On-board power filtering and transient suppression circuits suppress electromagnetic interference from inverters, servo drives and contactors, ensuring stable operation under harsh factory conditions. The front panel is equipped with LED indicators for power status, CPU heartbeat, network link and fault alarm, helping maintenance technicians quickly locate boot failure, bus timeout and communication faults during commissioning and routine inspection. The PCB adopts industrial-grade electronic components and reliable EMC protection design, capable of resisting vibration, dust and temperature fluctuation in semiconductor equipment, aerospace test platforms, power plants and automated production lines. This legacy Pentium III VME CPU board is mainly supplied as spare replacement parts for existing XYCOM VME automation systems. Users need to confirm BIOS version, memory compatibility and backplane definition before installation. A conformal coated version is optional for high humidity, dusty and corrosive industrial sites. This model is widely used in supervisory control, high-speed data logging, complex test station host and old VME embedded computing system retrofit projects.

This pentium iii vme single board computer adopts standard 6U dual-slot VME rack mount structure. It draws power from the VME backplane. LED indicators display power status, CPU activity and network status for convenient on-site inspection. The operating temperature range is 0°C to 65°C, storage temperature ranges from -40°C to +85°C, relative humidity 5% to 95% non-condensing. It complies with industrial shock, vibration and EMC standards and has CE certifications. It supports memory mapping and peripheral configuration backup for fast recovery after hardware replacement.

This XYCOM XVME-660 processor module is widely applied in legacy VME control racks and industrial automation upgrade projects. It serves as high-performance x86 host to execute complex control software, collect field measurement data and realize network transmission. As a reliable discontinued spare part, the XYCOM XVME-660 retains original VME bus timing and firmware compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
