# VORAGO Technologies

> VORAGO Technologies is an Austin, Texas fabless semiconductor company that designs radiation-hardened and extreme-temperature microcontrollers and microprocessors for aerospace, defense and industrial systems. Its patented HARDSIL process hardens standard commercial silicon against radiation and heat using conventional high-volume manufacturing, letting spacecraft, satellites and downhole tools run Arm Cortex-based compute in environments that would destroy ordinary chips.

- **Founded:** 2004
- **Headquarters:** Austin, Texas, United States
- **Founders:** Bernd Lienhard (CEO (joined later; 30+ years semiconductor experience, ex-AMD, ex-Freescale))
- **Team size:** ~37 employees
- **Products:** HARDSIL Technology, VA10820 (Arm Cortex-M0 MCU), VA41630 (Arm Cortex-M4 MCU), VA4 rad-tolerant family, VA5 dual-core family (Arm Cortex-M55)
- **Notable:** Patented HARDSIL radiation-hardening process usable on standard high-volume fabs, VA41630 earned DLA QML-Q+ certification, the highest U.S. government reliability assurance, Rad-hard MCU demonstrated in-flight reconfiguration of AMD space-grade FPGAs (2024)

## Products & services
