Product overview
The GR712RC integrates two fault-tolerant LEON3FT SPARC V8 processor cores for space and aeronautics applications. Each core includes instruction and data caches and a floating-point unit, while EDAC protects on-chip memory and external-memory interfaces. The system-on-chip combines SpaceWire, MIL-STD-1553, CAN, Ethernet, serial, and telemetry/telecommand interfaces with timers, GPIO, and debug support. A configurable I/O switch matrix allows interface allocation to be adapted to the system design. The device is offered in a ceramic flat package and supports development of redundant control, communications, and onboard-processing functions within a single processor component.
