Cobham Gaisler AB provides IP cores and supporting development tools for embedded processors based on the SPARC architecture. We specialize in digital hardware design for both commercial and aerospace applications

GR718B Development Board

The GR718B development board has been designed to support the development and fast prototyping of systems based on the Cobham Gaisler GR718B Radiation-Tolerant 18x SpaceWire Router.

The GR718B Development Board comprises a custom designed PCB in a 6U Compact PCI format, making the board suitable for stand-alone bench top development, or if required, to be mounted in a 6U CPCI Rack, or in a bench-top enclosure. The principle interfaces and functions are accessible on the front and back edges of the board, and secondary interfaces via headers on the board.GR718B development board


  • GR718B Radiation-Tolerant 18x SpaceWire Router
  • Power, reset, clock and auxiliary circuits
  • Mezzanine connector to provide access to the status and control signals of the GR718B device, and to enable a user defined mezzanine to be implemented
