Datasheet
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. Avalanche’s 3rd Generation P-SRAM using our 22nm high reliability pMTJ STT-MRAM enables the next generation of distributed edge processing in space for Low Earth Orbit Satellites. These memory devices are offered with either a Serial Peripheral Interface (SPI) or a parallel interface (x32). The products on this page are ideal for aerospace and defense applications.
