RAD-TOLERANT
VA42620
Arm Cortex-M4 Microcontroller
Built for the Demands of New Space
The VA4260 sets a new standard as the most integrated RTBD solution available, providing unmatched functional density to meet the demanding requirements of space-based application.
Specifications
The VA42620 mirrors the VA41620 feature set, including its external Serial Peripheral Interface (SPI) Non-volatile memory (NVM) architecture, with radiation and thermal protection optimized for low Earth orbit constellations and high-altitude platforms.
