Heating, Ventilation and Air Conditioning (HVAC)

An HVAC unit requires an MCU with networking support to implement a linked configuration between the main unit and distributed motor units. 

Body Control Module (BCM) / LED Head Light Unit

A body control module (BCM) integrates several functions, including various lights and door locks. It has a gateway function for communication with a CAN/CAN-FD or LIN. 

Electric Sliding Door

Powered door units that use motors to open and close doors require network functions as well as three-phase motor control capabilities for powering the opening and closing operations. 

Electric Window Lifter

The main (driver side) MCU of a power window or door unit requires CAN/CAN-FD/LIN networking capabilities, and the sub-MCU (passenger side/back) must support LIN networking.

Windscreen Wiper
