The invention relates to a microcontroller system for safety-critical motor vehicle systems, comprising a plurality of subsystems (A, B) arranged on a common chip (1), at least one of said subsystems having more than one channel, and being characterized in that it is designed to carry out a plurality of operating modes. The subsystems (A, B), in a first operating mode, are operated independently of each other and communicate with each other via an on-chip interface (A27, B27). In a second operating mode, at least one of the subsystems (A, B) is operated by means of data transmission means (A25, B26, A26, B26) and using non-local resources (A13-1, B13-1,..., A18) of at least one further subsystem (A, B) and/or at least one of the subsystems (A, B) is operating and at least one further subsystem (A, B) is inactive. The invention further relates to a method for operating such a microcontroller system and to the use thereof.
