STMicroelectronics SR6Px Stellar P Motion Control Microcontrollers
STMicroelectronics SR6Px Stellar P Motion Control Microcontrollers are Stellar-integrated MCUs designed to meet the requirements of domain controllers and ECUs with high integration requested in the architectures of connected, updateable, automated, and electrified cars. The MCUs offer superior real-time and safe performance with high ASIL-D capability. HW-based virtualization technology eases the development and integration of multiple source SW onto the same HW whilemaximizing the resulting SW performance. SR6Px components offer high-efficiency OTA reprogramming capability with fast image download and activation at almost no memory overhead. This is thanks to the unique built-in SR6 dual image storage tailored to OTA reprogramming needs that provides high-speed security cryptographic services, for instance, network authentication.
