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. In addition, high-speed operation performance is needed to implement automatic-reversing safety functions.

Renesas offers a broad lineup of compact, high-performance microcontrollers (MCUs) that meet these requirements. For further compactness, we supply custom ASIC products that incorporate the power supply, communication driver and other functions in a single package, as well as MCUs with integrated regulator and LIN driver functions.
