| Advanced connectivity and security capabilities
| Multiple Arm Cortex-R52 cores integrated
| Power consumption minimized with 28nm FD-SOI

STMicroelectronics announced on the 17th the launch of the Stellar automotive MCU product family for automotive domain controllers.

The Stellar MCU supports next-generation automotive architectures where a wide range of domain controllers (drivetrain, chassis, ADAS, etc.) play a critical role. These domain controllers enable data fusion from connected sensors, transitioning to software and data-driven architectures while reducing harness complexity and electronic component weight.

The Stellar product family combines the advantages of 28nm FD-SOI with on-chip PCM (Phase Change Memory), advanced packaging, and multiple Arm Cortex-R52 cores, enabling operation at frequencies up to 600 MHz. It integrates over 40 Mbytes of PCM while minimizing power consumption in demanding high-temperature environments. The Stellar MCU is manufactured at ST's 12-inch Crolles facility.

Key applications include smart control for hybrid powertrains, extensive electrification of automotive systems with onboard chargers, battery management systems, DC-DC controllers, smart gateways, ADAS, and vehicle stability control.

ST is currently supplying samples of the first Stellar MCU, which integrates an Arm Cortex-R52 core at 400 MHz clock speed with 16 Mbytes PCM and 8 Mbytes RAM in a BGA516 package. Stellar-based control devices from major customers are currently undergoing road testing.

Marco Monti, President of ST's Automotive and Discrete Group, stated, "The Stellar MCU delivers the secure real-time performance required for new domain controllers supporting data-driven services. The data-driven services industry is expected to reach 1.4 trillion dollars by 2030."

He continued, "The Stellar MCU is designed to support a new software-centric architecture that will enable the creation of new revenue streams. New features can be installed remotely without compromising automotive safety and security performance, enabling the integration of functions from multiple control devices into larger domains."

Lakshmi Mandyam, Vice President of Automotive for Arm's Embedded and Automotive Business Unit, stated, "To realize applications such as autonomous driving and smart powertrain control, next-generation automotive platforms must meet demanding real-time and safety requirements. The energy efficiency and functional safety features of the Cortex-R52, combined with its high performance and strong integration with ST's optimized multi-core SoC architecture, will meet the demand for these platforms."
