The CPU-71-15 is a high performance Single Board Computer (SBC) based on the VMEbus 6U form factor. The CPU-71-15 is offered in both convection cooled and ruggedized conduction cooled variants, it will meet the needs of numerous commercial and military applications requiring maximum processing power, low power consumption, and small physical footprint.

At the heart of the CPU-71-15 is an Intel® 2nd Generation Core™ i7 ULV Sandy Bridge Processor and QM67 Cougar Point Platform Controller Hub (PCH). These two devices form the central processing backbone of the design. With a dual-channel memory controller integrated in the processor, the CPU-71-15 supports up to 8 GBytes of DDR3 SDRAM running at up to 1333 MHz. The CPU-71-15 routes one of the i7’s two x8 gen 2 PCIe to the two on-board XMC sites.

One of the QM67 PCH’s x1 gen 2 PCIe is routed to a PCIe to PCI bridge (PLX8112) that supports PCI bus for the two on-board PMC sites and the Universe IID PCI-VMEbus interface controller. Another x1 gen 2 PCIe lane is routed to an Intel 82579 10/100/1000BaseT ethernet with front panel access.

The QM67’s x4 PCIe is routed to an 82571EB dual 10/100/1000 BaseT, routed to either P2 or P0 in compliance with VITA 31.1 ethernet backplane network. Three RS232 ports and an LPT1 port are also routed to P2.

Operating system support is provided for VxWorks, Linux, and Windows
