Networked Door and Mirror
Vehicle doors continue to evolve in the areas of safety and functionality. Silicon Labs’ C8051F5xx automotive MCUs are compelling solutions for controlling all door and integrated mirror functions. The C8051F5xx MCUs offer a crystal-less CAN bus and LIN bus communication gate between the body control module (BCM) and the door functions.
For the motor control for window lift and mirror position, the C8051F5xx provides high processing power, providing interlock and pinch signature algorithms to simplify automotive window obstruction detection and eliminate the need for a separate interlock system. For vehicles with passive entry systems, the door handles need a touch sensor with excellent outdoor performance and are suitable for use with gloves. Silicon Labs’ C8051F99x capacitive touch sense MCUs lead the industry in lowest power, highest capacitive touch performance, and best value/performance ratio.
