STMicroelectronics has unveiled automotive microcontrollers (MCUs) that have been optimised for electric vehicles and centralised (domain and zonal) electronic architectures.
In current EVs, high-efficiency SiC-based (silicon carbide) power modules enable the greatest driving range and faster charging. Until now, however, they have required dedicated high-speed signal processors to control the advanced SiC power semiconductors.
ST’s Stellar E MCUs have been designed for the next generation of software-defined EVs, and integrate high-speed control-loop processing on-chip. One MCU can now control the entire module. This simplifies the module design, saves costs, and eases compliance with automotive safety and security standards.
The MCUs extend ST’s Arm-based Stellar family and are designed from the ground up and as a powerful, centralised domain and zone controller, the family simplifies automotive electrical architectures for increased power, flexibility, and safety.
Currently, the MCUs family includes…
