RL78 Microcontrollers Help Reduce System Cost and Size

We are surrounded by electrical appliances using motors. In recent years, the variety and numbers have continued to increase, and the controls that are required have grown more diverse. After the 78K and R8C Family, the RL78 microcontrollers (MCUs) have been used in a wide range of applications that use motors. Among the broad device lineup, the RL78/G1F inherited RL78/G14 features and is highly suitable for motor control solutions. On top of the devices to realize motor control, Renesas also provides solutions to aid the development of motor control solutions.
