GR-CPCI-UT699 LEON3-FT CPCI Development Board

The GR-CPCI-UT699 development board has been designed to support the development and fast prototyping of systems based on the Cobham UT699 32-bit fault tolerant LEON3-FT SPARC V8 processor.

The UT699device is targeted for use in high reliability applications and incorporates failure tolerance by design features including TMR, parity protection and EDAC for external memories. The GR-CPCI-UT699 board comprises a custom designed PCB with a 6U 8HP Compact PCI front panel, making the board suitable either for stand-alone bench top development, or for installation in a 6U high Compact PCI rack. All primary interfaces and functions are accessible on the front panel connectors.

The board is capable of operating either as a stand-alone board or as a compact PCI plug-in card in either a system or peripheral slot. Expansion to user's peripherals and circuits can be implemented either in an adjacent slot via the PCI interface or as a mezzanine board via the memory expansion connections.
