Quad-Core LEON4 Next Generation Microprocessor Development Board
The GR-CPCI-GR740 evaluation board has been designed for evaluation of the GR740 device:
The GR-VPX-GR740 Development Board is available for use with OpenVPX and SpaceVPX environments.
GR740 SBC Reference design
The GR740 SBC is a reference design for a single-board computer based on the GR740 and the Microchip RTG4 radiation-tolerant FPGA.
The reference design data package consists of schematics and other design files required for developing a single-board computer for flight.
Availability
The GR740 in ceramic package is available with QML-Q and QML-V qualifications.
The GR740 in plastic package is available with ECSS Q ST 60 13C class 2 qualification.
Detailed ordering information is described in the GR740-UM-DS.
