Curtiss-Wright Controls Embedded Computing (CWCEC), a business group of Curtiss- Wright Controls (Charlotte, NC), has introduced 5-slot natural convection-cooled rugged ½ ATRstyle 3U CompactPCI and VPX systems. The MPMC-935x Multi-Platform Mission Computers feature built-in power supplies and payload modules. Modules include Intel® and Power Architecture® processor boards, Xilinx® FPGA processors, and I/O modules. Curtiss-Wright offers six standard MPMC-935x configurations that range from 1 to 5 processing nodes, along with I/O complements of serial ports, Gigabit Ethernet switching, and graphics.

With an integrated fan assembly, the MPMC-935x system cools multiple SBCs and FPGA processor modules. Optimal system cooling is ensured via thermal transfer between card edges of its conductioncooled 3U cPCI cards and the side walls of the system enclosure. The MPMC-935x uses advanced packaging techniques to provide optimal processing power in a rugged enclosure that measures a compact 600 cubic inches. Weighing less than 20 lb, the device operates in external air temperatures from 55°C to 71°C, while dissipating as much as 350W. The rugged enclosure meets military specifications including MIL-STD-810 for environmental conditions, MIL-STD-461 for EMI, and MIL-STD-704 for power.
