Product overview
Description
Stellar integration MCUs have been designed to meet the requirements of domain controllers and ECUs with high integration requested in the architectures of connected updatable automated and electrified cars. They have superior real-time and safe performance (with highest ASIL-D capability). Bringing hardware-based virtualization technology to MCUs, they ease the development and integration of multiple source software onto the same hardware while maximizing the resulting software 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. They also provide high-speed security cryptographic services, for instance for network authentication.
