RAD-TOLERANT
VA54230
Dual Core Arm® Cortex®-M55 Microcontroller
Cost-Optimized Mixed Signal Compute Engine
The rad-tol VA54230 is the twin chip to the rad-hard VA53230 —engineered to be functionally identical in every way except with rightsized radiation performance for Low Earth Orbit (LEO) at a fraction of the cost. The VA54230 uses our unique new Radiation Tolerance by Design (RTBD) approach for mission-matched reliability and breakthrough price/performance, at a fraction of the cost.
