RAD-HARDENED
VA53230
Dual Core Arm® Cortex®-M55 Microcontroller
Accelerated Dual Core Performance
The radiation-hardened VA53230 microcontroller delivers the dual-core performance and full feature set required to accelerate your entire space or satellite system versus single core VA4 MCUs. It includes mixed signal, connectivity, timing and motion controllers, along with patented HARDSIL® technology for the highest radiation protection performance required in MEO, GEO and beyond.
Specifications
Engineered for extreme environments, the VA53230 is targeted to run up to 200 MHz with ECC-protected program and data memory for high-throughput, low-latency computation - ideal for onboard payload control and spaceflight avionics.
