The MCXT Single Board Computer

The MCXT single board computer is a PICMG® 1.3 dual-processor SBC configuration designed to excel in the most demanding server-class computing applications.  The MCXT’s processor configuration provides two Quad-Core processors with four execution cores per processor.

For dual-processor board configurations, each processor has an independent system bus to reduce bottlenecks while maximizing throughput. The four-channel memory interface features DDR2-667 FB-DIMMS with a maximum of 16GB.  The processing power and configuration flexibility built into the MCXT single board computer provides system designers with an ideal technology fit for their server-class PICMG 1.3 computing applications.

Key features of the MCXT single board computer include:

  • Designed for computing applications requiring Quad-core Intel® Xeon® processors
  • Maximum memory bandwidth via a four-channel DDR2-667 memory interface
  • Two PCI-Express x8 lanes and one PCIe x4 lane supports backplane card slots and I/O
  • Coupled with a compatible backplane, this SBCcan support PCIe, PCI-X, or PCI option cards
  • PICMG 1.3 SBC with on-board SATA II RAID, video, USB, Gigabit Ethernet ports
The MCXT single board computer maximizes system ROI with long-life, embedded components which drive an extended SBC product availability of seven years or more.  As with all of our single board computers, the MCXT is designed with a standard system BIOS version that is maintained under strict revision control.

However, BIOS flexibility is built in by offering various BIOS modifications that may be needed to meet unique system requirements and maintains strict revision control for custom BIOS variations. The MCXT is designed, manufactured and supported in the U.S. facilities and is covered by our exclusive five-year factory warranty.
