About
The VA54230 is the radiation-tolerant-by-design member of VORAGO’s VA5 family, sharing the same silicon DNA, design database and fab as the radiation-hardened VA53230 to ensure total consistency across a satellite fleet. It targets LEO missions where full rad-hard performance is not required, offering the same dual Cortex-M55 core architecture, memory, and interface set at reduced cost, with 100% pin/design compatibility allowing a drop-in swap between protection levels (‘One Design. Any Orbit.’).
