Cortex-R52, Cortex-M7 Stellar Automotive Microcontrollers from STMicroelectronics

UDE Microcontroller Debugger solutions for Stellar 32-bit Automotive MCUs

ST’s Arm®-based Stellar platform reduces the complexity of new vehicle architectures and their electrification. ST's Stellar automotive microcontrollers address the requirements of modern vehicle nodes. These range from application management and high data-stream control to efficient actuation and power conversion subsystems.

Stellar G and P are the first Arm® Cortex®-R52/-M4 automotive microcontroller family with on-chip Phase Change Memory (PCM) for real-time multi-core performance. The Stellar family combines multiple leading-edge technologies to form an automotive domain controller for applications for Drivetrain, Chassis, and Advanced Driver Assistance Systems (ADAS).

Stellar E family is optimized for software-defined electric vehicles and with its functions for fast execution of control loops. The Stellar E family is primarily intended for use in power electronics applications such as on-board chargers or DC/DC converters. It is based on two Arm® Cortex®-M7 cores, each clocked at 300 MHz, which can be operated either in a dual-core configuration or, for the highest demands on functional security, as a single core with lockstep. For applications with increased security requirements, the integrated Hardware Security Module (HSM) offers, among other things, functions for accelerating cryptographic tasks. The MCUs are equipped with up to 2 MB on-chip flash. Split into two banks the code Flash allows software updates Over-The-Air (OTA).
