|GR-CPCI-GR740||The GR-CPCI-GR740 development board has been designed to support the development and fast prototyping of systems based on the Cobham Gaisler GR740 quad-core 32-bit fault tolerant LEON4FT SPARC V8 processor. The board supports MIL-STD-1553B, 10/100/1000 Base-T Ethernet, eight SpaceWire ports, 32-bit PCI, two CAN ports, two UARTs, Serial Peripheral Interface, on-board Flash and SDRAM. On-board USB and SpaceWire debug ports are also available.|
|The GR712RC-BOARD evaluation board is capable of running at a system clock speed of 100MHz. The board is a double Eurocard form factor used in a standalone bench-top configuration. The board supports MIL-STD-1553B, 10/100 Base-T Ethernet, six SpaceWire ports capable of running at up to 200Mbits/s, two CAN ports, on-board FLASH, SRAM, and SDRAM. A USB debug port is also available on-board.|
|GR-CPCI-UT699||Development board with the UT699 LEON3FT SPARC V8 microprocessor. The board is cPCI form factor and can also be used in a standalone bench-top configuration. The board supports 32-bit/33MHz PCI, Ethernet, 4 SpaceWire ports capable of running up to 200Mbit/s, 2 CAN ports, on-board FLASH, SRAM, SDRAM, and socket for a PROM device. A USB debug port is provided.|
|AX9-4250252-000/001 LEAP *||The Cobham LEAP provides a flexible development platform for customers wanting to develop software that works on the Cobham UT700 Standard Product with minimal cost investment. The Cobham LEAP has a Cobham UT700 LEON 3 FT prototype grade device with 8 Mbytes NV memory storage and 32Mbytes SDRAM (both commercial memory), along with one USB UART interface and one 10T/100 Mbit/s Ethernet port. It also includes a JTAG interface for programming and debug of UT700 LEON 3FT (requires XILINX USB Platform Cable) along with one 192-pin mezzanine card expansion connector and an on-board Programmable LEAP main clock.|
|ALExIS Development |
|Cobham LEON Experimenter's Interface System is a ready-to-run development platform for customer applications with flexible architecture supporting quick path-to-flight after development. The ALExIS platform is a 3U cPCI chassis which comes with one non-flight UT699 SBC, a video card, a power card and two cPCI slots for future card expansion. Pre-loaded operating systems and applications drivers are also included with the ALExIS.|
Prototype SBC for the
ALExIS Development System
|Off-the-shelf 3U cPCI form factor Single Board Computer (SBC) based on the UT699 LEON 3FT 32-bit SPARC™ V8 Microprocessor. The UT699 SBC addresses size (160mm x 100mm), weight (<4 pounds) and power (<5.5W). The UT699 SBC has a path to flight (non-flight and flight variants to be available). The UT699 SBC includes an FPGA, volatile and non-volatile memory, 10 user defined A/D channels, 194-pin mezzanine connectors (2) and the following interfaces: SpW (4), RS-485 (1), cPCI 33MHz/32bit (1), JTAG (2), 10/100 Ethernet (1) for terrestrial use. This subject prototype (non-flight) UT699 SBC is only available in the ALExIS (Cobham LEON Experimenter's Interface System) development platform. For more information, please contact your Sales Representative or you may contact us directly.|
|* Users performing software development targeting a future UT699E design may still use the LEAP development system since the UT699E device implementation is a subset of the UT700.|
