RAD-HARDENED
VA41628
Arm Cortex-M4 Microcontroller
Cost-Optimized, Low-Power Digital Compute
The VA41628 offers the full radiation-hardened reliability (>300 krad TID) of the VA4 Arm® Cortex®-M4 lineup in a cost-optimized, digital-only package.
Specifications
Featuring a 50 MHz clock speed designed to minimize power consumption, it is the ideal processing solution for digital avionics, FPGA management, and thruster control where analog interfaces are handled externally.
