STMicroelectronics announced the Stellar P3E, its first automotive microcontroller that embeds a Neural‑ART AI accelerator. The chip is engineered for software‑defined vehicles, combining high‑performance real‑time control with low‑power AI inference to enable virtual sensors, predictive maintenance and other advanced automotive applications.
The Stellar P3E houses a dedicated neural processing unit that delivers inference speeds in the microsecond range, roughly 30 times more efficient than conventional MCU cores. It runs two 500 MHz Arm Cortex‑R52+ cores and scores over 8,000 on the CoreMark benchmark. The package also incorporates ST’s proprietary xMemory phase‑change memory, which offers twice the density of standard embedded flash while meeting automotive safety qualifications.
The launch targets the rapidly expanding automotive edge‑AI market, where the trend toward X‑in‑1 ECU architectures is consolidating multiple vehicle functions into a single control unit. By integrating AI acceleration, rich analog content and intelligent power management, the Stellar P3E positions ST as a differentiated supplier against rivals such as Texas Instruments and Infineon.
Production of the Stellar P3E is slated to begin in the fourth quarter of 2026. ST will support developers with its Edge AI Suite and Stellar Studio tools, enabling rapid deployment of AI applications on the new platform.
Luca Rodeschini, ST’s Group Vice President and General Purpose and Automotive Microcontrollers Division General Manager, said the chip “sets a new benchmark for automotive electrification by combining high‑performance real‑time control and edge AI in a single device that meets the highest automotive safety levels.”
