Product overview


Stellar integration MCUs have been designed to meet the requirements of domain controllers and ECUs with high integration requested in the architectures of connected update-able automated and electrified cars. They have superior real-time and safe performance (with highest ASIL-D capability). Bringing HW based virtualization technology to MCUs, they ease the development and integration of multiple source SW onto the same HW while maximizing the resulting SW performance. They offer high efficiency OTA reprogramming capability with fast new image download and activation at almost no memory overhead thanks to SR6 unique built-in dual image storage tailored to OTA reprogramming needs and provide high speed security cryptographic services, for instance for network authentication.
