Automotive electronics are the driving force for real-time controller area networks (CAN) with up to 100 nodes in a future high-end vehicle. The mixed mechanical-electronic (mechatronic) control units in such a network require single-chip microsystems to achieve reliable cost-effective systems integration with a minimum number of components and interconnections. The mixed digital-analog microcontroller meets these mechatronic requirements. In addition to a complex 16 b flash programmable microcontroller, it includes a set of robust analog I/O peripherals such as voltage regulator, bus interface, and sensor interface with 40 V break-down, so that no external interface ICs are required.
