Gen 3 Products

Radiation-hardened, general-purpose, multi-core processors and FPGAs are used in on-board computing for applications such as military surveillance and weapons systems, human-rated spacecraft, habitats and vehicles, and robotic science and exploration platforms. System applications range from small satellites to large flagship-class missions. These processors and FPGAs need highly reliable boot code and configuration memory.
