Product overview
The UT699E is a fault-tolerant SPARC V8/LEON3FT processor for embedded computing and system control. A seven-stage pipeline, separate instruction and data caches, and a floating-point unit support application processing. The device integrates memory control, Ethernet, PCI, SpaceWire, CAN, timers, and interrupt functions through an AMBA interconnect. Enhanced caches and RMAP support on all four SpaceWire ports extend the earlier UT699 architecture. Its SPARC V8 compatibility supports established compilers, kernels, and development tools. Ceramic package and screening options provide a path to selecting the processor configuration for spaceborne computers, avionics boards, and other high-reliability control applications.
