System chips for automotive applications

Abstract

Two examples of single chip system ICs for automotive applications are described. Both are equipped with an 8-bit microcontroller, double poly EPROM for software code, various standard microcontroller peripherals, voltage regulators for battery interface, A/D for sensor interface, 100 m/spl Omega/ power devices for load drive, and physical layers for line communication interface. All integrated in a single chip. The challenges of diffusion, assembly and test processes are addressed.
