The GR-CPCI-GR740 development board has been designed to support the development and fast prototyping of systems based on the our GR740 quad-core 32-bit fault-tolerant LEON4FT SPARC V8 processor.

The GR-CPCI-GR740 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. The  GR-CPCI-GR740 Development Board comes as standard with a dedicated accessory board which provides access to additional I/O interfaces.

Features

• GR740 quad-core 32-bit fault-tolerant LEON4FT SPARC V8 processor

  • Assorted jumpers and Test Points for configuration and test of the board
• To accommodate the optional/alternative I/O interfaces the accompanying accessory board provides
  
  • Dual MIL-1553 Interface (Transceiver/Transformer and D-sub 9 Male connector)
  • Dual CAN Interface (CAN Transceivers and two D-sub 9 Male connectors)
  • Two Serial UART (RS232 transceivers and two D-sub 9 female connectors)
  • SPI interface (available via 10 pin header)

Note: The product picture on this page show the board with a socket holding the GR740. The standard configuration of the GR-CPCI-GR740 is to have the GR740 device directly soldered on the PCB.
