RAD-HARDENED
VA41630
Radiation-Hardened Arm® Cortex®-M4
Provides the Highest Functional Density for Space-Based Applications.
The radiation-hardened VA41630 combines 100 MHz Arm Cortex-M4 performance, full mixed-signal peripherals, and integrated non-volatile FRAM into a single, high-reliability architecture.
Specifications
Built with >200 krad(Si) TID protection to virtually eliminate single-event latch-ups, it streamlines board design and minimizes SWaP for primary flight computers, satellite bus controllers, and 15+ year space missions
