Abstract
A microcontroller system for safety-critical motor vehicle systems is provided. The microcontroller system includes a plurality of subsystems arranged on a common chip. At least one of the subsystems has more than one channel and is designed to carry out a plurality of operating modes. The subsystems, in a first operating mode, are operated independently of each other and communicate with each other via an on-chip interface. In a second operating mode, at least one of the subsystems is operated by data transmission means and using non-local resources of at least one further subsystem and/or at least one of the subsystems is operating and at least one further subsystem is inactive. A method for operating such a microcontroller system and to the use thereof is also provided.
