The complexity of new car architectures requires automotive microcontrollers to deliver higher capabilities than ever before. ST's Stellar Integration MCUs offer safe, secure and deterministic solutions for next-generation vehicle architectures. The Stellar SR6 series is designed to effectively integrate with domain controllers for electrification and drivetrain systems as well as with zone controllers for automotive body and convenience applications.
Powered by Arm® Cortex® R52+ cores, this architecture integrates support for real-time applications, providing multiple layers of protection throughout the entire device architecture. This ensures complete and safe function isolation as well as enhanced hardware virtualization capabilities.
Developed in power-efficient 28nm FD-SOI technology, Stellar MCUs benefit from ST's proprietary phase-change memory (PCM) technology. Not only does it feature the industry’s smallest memory cell for automotive MCUs, but it is also pioneering a transformative breakthrough in automotive memory technology.
Safety certified
Based on the results of the final assessment performed in May 2024 by Exida, as reported in the Functional Safety Assessment Report (available upon request), the work products delivered by ST within the project have been found to comply with the relevant requirements of the ISO 26262:2018 standard, up to and including ASIL-D.
Applications
Stellar SR6 automotive microcontrollers are specifically engineered to meet the stringent demands of new vehicle architectures, electrification, integration of motion control systems, safety-critical MCUs for systems such as ADAS, high-end body integration, zone control.
