VORAGO Unveils Low-Cost Radiation-Tolerant Chips Designed for LEO Constellations

VORAGO Technologies has launched the world’s first radiation-tolerant microcontrollers specifically designed for the rapidly expanding LEO satellite constellation market, offering deep-space-grade resilience at up to 75% lower cost. The new devices, four ARM Cortex-M4–based microcontrollers within the VA4 family, will begin shipping in early 2026.

The chips introduce radiation-tolerance by design, embedding protection directly into the silicon rather than relying on bulky, multi-chip redundancy or upscreened commercial parts. This approach targets a market set to swell to 58,000–100,000 satellites by 2030, driven by LEO broadband constellations and Earth-observation fleets.

The company is offeringtwo tiers: the VA42620/630 for extended missions in harsher orbital environments or primary flight control, and the VA42628/629 optimized for short-life or lower-orbit missions. All are footprint-compatible with existing satellite architectures, enabling operators to upgrade reliability without redesign.

The launch expands VORAGO’s space electronics portfolio, which now includes both rad-tolerant and QML-Q+ certified rad-hardened devices building on the company’s deep-space heritage and recent introduction of its dual-core VA5 family for AI-enabled missions.

Cutting cost, size, and integration complexity, VORAGO aims to give commercial and government constellation operators a sustainable way to scale without compromising in-orbit resilience or contributing to failure-driven space debris.
