ABSTRACT

Automotive body network requirements have changed significantly in the last few years due to the introduction of OSEK and the increasing number of ECUs.

8-bit microcontrollers are and will stay widely used in a majority of automotive body applications. While a wide variety of powerful CAN controllers are available on the market for 16- and 32-bit microcontrollers, 8-bit microcontrollers still need too much CPU time for CAN communication management. This application note presents a new generation of CAN controllers optimized for 8-bit microcontrollers and designed to meet the needs of body applications.
