Product overview
The UT699 is a fault-tolerant 32-bit SPARC V8/LEON3FT processor with integrated memory control and communications peripherals. Its architecture combines separate instruction and data caches, a floating-point unit, timers, and interrupt handling with a 32-bit PCI interface. Four SpaceWire nodes, Ethernet, and dual CAN interfaces connect the processor to system data paths and peripherals. Hardened storage elements and error-detection and correction functions support operation in radiation environments. The SPARC V8 architecture enables use of established compiler and operating-system tools, while ceramic package and screening options allow the ordered device to be matched to the intended application.
