Curtiss-Wright Controls introduces new mission computer with hybrid VME/VPX backplane

ASHBURN, Va. 26 Oct. 2012. Curtiss-Wright Controls Defense Solutions (CWCDS) has introduced the MPMC-9H5x, a rugged subsystem with hybrid VME and VPX backplane support defined by the VPX (VITA 46/48) open standard. The MPMC-9H5x multi-platform mission computer is a 3U high 1/2 ATR flexibly configured rugged system that supports a mix of 3U and 6U VPX and 6U VME form factor modules with a standard backplane configuration. This system design achievement enables customers to transition from custom legacy VME and I/O configurations to take advantage of today's VPX-based processing and networking without having to redesign or replace their existing VME and I/O hardware. Supporting the full range of military ruggedization levels, the MPMC-9H5x is meant for ground and airborne vehicles that require an open architecture mission computer that supports flexible I/O and interface requirements.


The MPMC-9H5x is packaged in an a compact 3U 1/2 ATR form factor and equipped with power architecture processing. Optimal system cooling is ensured via thermal transfer between the conduction cooled VME and/or VPX cards module card edges and the side walls of the system enclosure. EMI filters and gaskets provide system security and increased reliability. Designed to meet the harsh environments typical of military and aerospace computing applications, the MPMC-9H5x's power supply and backplane feature nuclear circumvention circuits to meet gamma and neutron fluence events without damage.

The MPMC-9H5x's hybrid backplane provides support for one 6U VME, two 6U VPX and  two 3U VPX cards. The MPMC-9H5x is the first in a family of VME/VPX hybrid backplane-based mission computers from Curtiss-Wright. Variants with different configurations of form factor and architecture type will be announced in the future.

The MPMC-9H5x enables system designers to configure a hybrid computer environment comprising VME and VPX bus architecture cards in both 3U and 6U form factors, allowing module selection from a wide range of COTS module solutions to match the unique needs of their application. The MPMC-9H5x is designed to enable customers to upgrade the performance of their system without having to change their legacy custom I/O boards. This enables system designers to integrate additional features such as Ethernet and graphics processing without having to change their entire system design.

As a natural convection cooled system, the MPMC-9H5x is designed for operation in harsh environments without the need for a base plate of forced air cooling.

The standard system configuration of the MPMC-9H5x is equipped with an integrated 28 VDC power supply unit and a Fire Control Processor (FCP) III card. The power supply can be ordered with an optional NED and circumvention output to the backplane.
