Ultra-Flexible, Safety Certifiable 3U VPX I/O Module

Curtiss-Wright

Curtiss-Wright’s Defense Solutions introduces its first avionics I/O module, the VPX3-611, an -based rugged 3U VPX module that can be configured with a virtually unlimited combination of safety certifiable I/O interfaces. Because DO-254 certification artifacts are available for the module’s I/O interfaces at the FPGA block macro-level, I/O configuration variants of the VPX3-611 can be created quickly and at minimal cost compared to the development of a custom solution. Safety certifiable I/O interfaces supported by the VPX3-611 include MIL-STD-1553B, ARINC 429, CANbus, asynchronous UARTS, discretes, in, analog out, Serial Peripheral Interface (SPI), and others.

The VPX3-611’s unmatched flexibility enables customers to select the specific mix of I/O needed to meet their unique application requirement. The module’s FPGA I/O blocks, which can be factory-configured to DO-254 Design Assurance Level (DAL) C and DO-178C DAL C, ease platform certification, speed time to market, and significantly reduce the cost and risk of developing safety certifiable electronics subsystems for commercial and military aviation platforms. An on-module “personality module” provides all required transformers, transceivers, and drivers for I/O .

The VPX3-611 also optimizes overall system performance by off-loading the system host from I/O processing tasks. What’s more, because the module supports a wide mix of I/O types, it can reduce board count by eliminating the need for multiple modules to address a wide variety of I/O requirements. This size, weight, power and cost (SWaP-C) optimized COTS module is available in both air and conduction-cooled versions.

Comprehensive Safety Certifiable Data Artifact Packages

The VPX3-611 was developed under Curtiss-Wright’s Safety Certifiable Module initiative using a development process that results in DO-254 and DO-178 Design Assurance Level (DAL) C certifiable product and supporting artifacts. The VPX3-611’s DO-254 and DO-178C Artifact Kits feature reusable design artifacts and support documents that make it ideal for use in demanding military and civil aerospace applications.
