Method for providing a generic interface and microcontroller having a generic interface

摘要

A microcontroller for a control unit or a vehicle control unit, includes a central processing unit (CPU), at least one interface-unspecific input module, at least one interface-unspecific output module, at least one routing unit and at least one arithmetic unit for processing interface-specific information. The microcontroller is configurable so that the at least one interface-unspecific input module, the at least one interface-unspecific output module, the at least one routing unit and the at least one arithmetic unit for processing interface-specific information fulfill the functions corresponding to one of multiple serial interfaces, in particular of SPI, UART, LIN, CAN, PSI5, FlexRay, SENT or Ethernet. In addition, the arithmetic unit is configured to generate an entire output message frame from the second payload data as output data and to transmit the same to the interface-unspecific output module.
