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.
Specifications
The VA54230 offers Low Earth Orbit (LEO)-optimized Radiation Tolerance Built by Design (RTBD) at significantly lower cost than it’s rad-hard counterpart. Designing once eliminates NRE. Unlike up-screened COTS, RTBD handles mitigation natively—eliminating EDAC "software tax" and keeping your MCU focused on mission control.
