STMicroelectronics has unveiled new automotive microcontrollers that are optimized for electric vehicles and centralized (domain and zonal) electronic architectures and enable EVs to become more affordable, drive further, and charge faster. These new Stellar E MCUs extend ST’s Arm-based Stellar family and are designed from the ground up with the car as a platform in mind.
These MCUs integrate high-speed control-loop processing on-chip include Stellar P series for integration and vehicle control and the Stellar G series for body applications. The Stellar family architecture features multiple Arm Cortex cores that deliver high performance with the opportunity for lock-step redundancy and support real-time hardware virtualization. Moreover, all Stellar devices are designed for software upgradeability through secure over-the-air (OTA) updates.
Stellar SR5E1 is the first product in the Stellar E series that is designed for EV on-board chargers (OBC) and general DC/DC converters and is now sampling to lead customers.
