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 or LIN. 

High-Intensity Discharge Lighting System (HID)

High-intensity discharge electric headlights, which have grown in popularity in recent years, require electronic control by an MCU. 

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/LIN networking capabilities, and the sub-MCU (passenger side/back) must support LIN networking.

Windscreen Wiper

Wiper control requires smooth motor control.Renesas offers a broad lineup of compact MCUs with 16-bit CPU cores that deliver high-performance motor control.
