Semiconductor developments for automotive systems

Abstract

The paper defines how complex automotive electronics has become and how advanced semiconductor technology is being developed to simplify the development of these systems. In order to handle the increasing processing bandwidth required, and to interface effectively with the many sensors and actuators on the modern motor vehicle, significant advances are being made in semiconductor technology. The types of systems which are becoming more complex are defined along with the reasons for becoming so. System are now being developed which can integrate together different types of semiconductor technology in order to reduce chipcount, size and increase performance and reliability. Analog, digital, power and even sensor technology is being merged in order to address the advanced automotive requirements. Examples are given of system chips and their impact on advanced automotive applications. Smart sensors are being developed which will make integrating many sensors simpler than ever before. The smart sensors will allow easier sharing of information between related systems such as chassis control systems (braking, steering, collision avoidance, etc.). The concept and application of such smart sensors is discussed. Several other advances in semiconductors for automotive applications are discussed such as Flash NV memory, power consumption issues and vehicular electronic communication protocols. The impact of these technologies on simplifying development of complex systems is made clear.
