1.2 Description
Stellar integration MCUs are designed to meet the requirements of domain controllers and ECUs with high integration, as required in the architectures of connected, updatable, automated, and electrified cars. They have superior real-time and safe performance (with the highest ASIL-D capability). Bringing hardware-based virtualization technology to MCUs, they ease the development and integration of multiple-source software on the same hardware while maximizing the resulting software performance. They offer high-efficiency OTA reprogramming capability with fast new image download and activation. They also provide high-speed security cryptographic services, for instance for network authentication.
