RAD-TOLERANT
VA42629
Arm Cortex-M4 Microcontroller
100% Compatible Twin For High-Speed Mixed-Signal Processing
As the radiation-tolerant twin to the VA41629, the VA42629 delivers integrated analog capabilities and high-speed processing with mission-matched 30 krad(Si) radiation protection.
Specifications
The VA42629 maintains complete functional compatibility—including external SPI NVM support and precision mixed-signal sensing—allowing engineering teams to qualify software once and deploy cost-effective controllers across LEO constellations and atmospheric defense platforms.
