"STMicroelectronics has introduced the Stellar P3E, the first automotive MCU with an embedded Neural-ART AI accelerator, designed to simplify X-in-1 Electronic Control Units (ECUs) by consolidating powertrain functions like the inverter, on-board charger (OBC), and DC-DC converter into a single module. The MCU enables smart sensing, predictive maintenance, and virtual sensor applications without the cost and complexity of a separate SoC. The microcontroller features four 500 MHz Arm Cortex-R52+ cores with 19.5 MB of xMemory, which is based on phase-change memory (PCM), offering roughly twice the density of embedded flash. The chip integrates multiple ADC channels for precise sensing, high-resolution PWM down to 102 ps for fine motor control, and 10 timer modules for deterministic real-time operation. Connectivity options include Gigabit Ethernet and CAN-XL, for high-speed, low-latency in-vehicle communication. Stellar P3E (SR6P3EC4/SR6P3EC6) specifications: MCU – SR6P3EC4 / SR6P3EC6 CPU Cores – 4x Arm Cortex‑R52+ cores at up to 500 MHz; [...] The post STMicroelectronics Stellar P3E quad-core Arm Cortex-R52+ automotive MCU features Neural-ART AI accelerator appeared first on CNX Software - Embedded Systems News."
