VA5 FAMILY
Accelerated Performance
For Next-Gen Space
Dual-Core Capability for Critical Payloads
The VA5 microcontroller family pairs two 32-bit Arm® Cortex®-M55 cores with mixed-signal peripherals, motor control, and a full communications suite, delivering the processing headroom that single-core designs can't. Each device is offered in radiation-hardened and radiation-tolerant versions, so the choice comes down to the environment, not the design.
Mission-Matched Dual Core Power
With two 32-bit Arm® Cortex®-M55 cores running up to 200 MHz, both the VA5 rad-hardened and rad-tolerant MCUs deliver high-throughput, low-latency processing for complex real-time control. Compared with VORAGO’s single-core VA4 workhorse, it offers 2x the speed and 5x the capability for advanced aerospace, defense, and autonomous systems. Advanced fault tolerance, protected program and data memory, communications, and analog-control interfaces provide a dependable platform for onboard payload control, flight systems, and other mission-critical applications.
Rightsized Radiation Performance From Leo to Geo
More Capability for Advanced Control
