VA5 Family of Rad-Hard and Rad-Tolerant Microcontrollers for Space, Defense, and Autonomous Applications

Featuring dual 32-bit Arm® Cortex®-M55 cores with integrated Floating-Point Units (FPU), the VA5 family provides the processing capability needed for complex real-time control and system management tasks. Its robust peripheral set—including Ethernet MAC with QoS, dual SpaceWire interfaces, motor controllers, and extensive analog and digital I/O—supports applications from satellite altitude control to propulsion management and robotics. With clock speeds up to 200 MHz and low-latency memory access, it delivers efficient performance for deterministic control under harsh conditions—exactly what’s expected from a rad-hard microcontroller built for mission success.

The VA5 family is engineered to thrive in radiation-heavy and temperature-extreme environments. Leveraging Dual Interlocking Cells (DICE), Triple-Mode Redundancy (TMR), and robust EDAC with scrub technology, this rad-hard dual-core MCU ensures continuous operation even in deep space missions or high-radiation defense systems.

Radiation tolerance is matched by the VA5’s architectural safeguards for continuous mission assurance. EDAC-protected SRAM and NVM, and dual watchdog timers plus a recovery watchdog ensure reliability in the most extreme conditions. Designed to integrate securely with spacecraft, defense electronics, and autonomous systems, the VA5 family of space-grade microcontrollers provide the trusted foundation for mission-critical applications that demand both performance and survivability.
