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.
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.
