Mobility is becoming greener, safer, and more connected. It is reshaping the Automotive industry and redefining our in-vehicle lives. Electrified vehicles, self-driving cars and new services provide more safety, added security and enhanced user experience. However, we need to change the way the functions are designed and updated, and find ways to simplify systems that continue to increase in complexity.
The Stellar platform consists of multiple series of automotive microcontrollers built around a versatile Arm®-based architecture. The Stellar P and G series are designed to support real-time virtualization of multi-ASIL ECUs. Stellar E series addresses the needs for electrification. All series boast an extensive array of I/Os and peripherals, ready for modern car ECU solutions. Stellar P & G product lines include xMemory, build on ST PCM technology, providing over 2X the memory density versus other eNVM technologies. Stellar with xMemory offers more headroom for today and future application needs.
Stellar MCUs meet the evolving needs for more powerful applications and centralized ECUs at the domain or zone level.
Stellar MCUs can:
- Securely and safely run several critical real-time functions
- Support the aggregation and dispatching of growing data streams
- Ensure efficient energy management
- Secure over-the-air software updates for managing vehicle lifecycles and deploying new and improved services

ST's Stellar platform benefits
28nm/18nm FD-SOI technology ensures better control of the system's power consumption for a more ecological footprint along with its inherent radiation immunity for improved reliability and availability of safety-critical systems.
xMemory: embedded high-density PCM enables more memory storage for our customers to support existing and emerging applications, over-the-air (OTA) software updates with zero downtime and offers unique data retention capabilities.
Stellar is the first 28nm product family assessed by a major certification authority as ISO 26262 ASIL D Safety compliant. This ensures automotive designs meet the highest ASIL safety requirements.
Its compliance with the ISO 21434 cybersecurity standard and UN155 regulation provides a future-proof solution, ensuring the highest levels of protection and integrity.
Stellar leverages the efficiency of Arm®-based high-performance, versatile architectures integrating multiple processing and virtualization. The system architecture comes with a strong and secure isolation enabling faster communication and reducing time-to-market. Stellar MCUs also integrate efficient accelerators for AI functions, data routing, analog-to-digital filtering, and several low-power modes.
