New radiation-tolerant microcontrollers introduced for satellite constellations

Vorago Technologies announced the release of four new radiation-tolerant microcontrollers designed for low Earth orbit applications, with first shipments expected in early Q1 2026. These chips address the reliability needs of satellite constellations while reducing costs by up to 75% compared to traditional space-grade electronics.

The VA4 family of microcontrollers uses ARM Cortex M4-based cores and includes extended-mission models for harsh orbits and cost-optimized versions suited to short or lower orbit missions. Radiation protection is embedded in the silicon, bypassing the need for multi-chip redundancy and offering integration into existing architectures without redesign.
