Within the automotive industry electronic implementations are increasingly being used to replace traditional mechanical control loops. Mechanical designs suffer from wear and tear caused by the constant movement of the component parts. Electronic designs increase the reliability while also reducing the manufacturing cost. One example of this is in X - by - Wire implementations. Traditionally there would have to be a mechanical link between the control signal and the motor which would respond to the input. In the X - by - wire implementation, the mechanical link is replaced by an electronic interface. The traditional control signal is digitized by the ADC and processed by the ARM7TDMI core. The core can then implement precision control using the on-chip DACs or PWMs to control the motor position. The central host processor would supervise all electronic components within an automobile. The ADuC702x series of parts can connect easily to this host processor across one of the three serial I/O interfaces present on-chip.
