RAD-TOLERANT

VA42628

Arm Cortex-M4 Microcontroller 

Built for the Demands of New Space

As VORAGO’s inaugural Radiation Tolerant By Design (RTBD) microcontroller, the VA42628 provides the full functional features of its rad-hard twin—the VA41628 —yet delivers mission-matched radiation performance at a fraction of the cost.
