STMicroelectronics Stellar automotive microcontroller (MCU) range

STMicroelectronics is driving safe, smart automotive electronics and advanced domain controllers with the introduction of its Stellar automotive microcontroller (MCU) family.

The MCUs support next-generation car architectures, which rely on broad ‘domain controllers’ for areas such as drivetrain, chassis and advanced driver assistance systems (ADAS). These domain controllers enable the transition towards software- and data-oriented architectures by providing data fusion from connected sensors while reducing harness complexity and electronic-component weight.

Combining the advantages of 28 nm FD-SOI, on-chip phase change memory (PCM), advanced packaging and multiple Arm Cortex-R52 cores, the range can operate at frequencies up to 600 MHz and integrate more than 40 MB of PCM while minimising power consumption even in harsh, high-temperature environments.

Major applications include smart control for hybrid powertrain, the broad electrification of car systems with onboard chargers, battery-management systems and DC-DC controllers, as well as smart gateways, ADAS and enhanced vehicle stability controls.
