RAD-TOLERANT
VA42630
Arm Cortex-M4 Microcontroller
Built for the Demands of New Space
As VORAGO’s inaugural Radiation Tolerant By Design (RTBD) microcontroller, the VA42630 provides the full functional features of its rad-hard twin—the VA41630 —yet delivers mission-matched radiation performance at a fraction of the cost.
Specifications
Built on the exact same architecture with integrated non-volatile memory, it is optimized for Low Earth Orbit (LEO), atmospheric, and terrestrial environments, allowing engineering teams to design once and scale seamlessly across orbits.
