Washing Machine (High-End)
详情介绍
Overview
Renesas has a wide-ranging lineup of MCUs that enable our customers to develop products that satisfy these requirements. The products in the RX24T Group and the RX63T Group are ideal for use as motor control MCUs, and those in the RX130 Group (for capacitive touch) and the RL78/G13 Group are designed for system control. These MCUs meet a variety of requirements for washing machine control, including wide-range motor torque, rotation rate control, and load variation.
