STMicroelectronics, a global semiconductor company supporting various electronic applications and customers, has achieved the simplification of high-efficiency power modules for electric vehicles by launching a new microcontroller (MCU) that supports software-defined electric vehicles.

ST recently unveiled 'Stellar E', a new automotive MCU optimized for electric vehicles and centralized (domain and area) automotive architectures.

ST’s Stellar E MCU, designed for next-generation software-defined electric vehicles, can control the entire module with a single MCU by integrating high-speed control loop processing into the chip.

This simplifies module design and reduces costs, as well as makes it easier to comply with automotive safety and security standards.

The new MCU is an extension of ST's Arm®-based Stellar family and was designed with automotive platforms in mind.

This product family of powerful centralized domain and zone controllers simplifies the automotive electrical architecture to improve power consumption, flexibility, and safety.

Currently, this MCU family includes the Stellar P series for integration and vehicle control and the Stellar G series for body applications.

The Stellar family architecture is a multi-Arm Cortex coreIt integrates to provide high performance and lock-step redundancy, and supports real-time hardware virtualization.

All Stellar devices are designed to allow software upgrades via secure Over-The-Air (OTA) updates.

“ST Vice President Luca Rodeschini stated, ‘The Stellar MCU enables advanced electrification while allowing for efficient energy management and flexible, software-defined vehicle lifecycle management. This platform completes a new value chain for electric vehicles with the new Stellar E devices. Manufacturers can securely update software wirelessly, enabling them to extend driving range and improve control strategies to enhance performance and power efficiency.’”
