Overview

Description

The RX111 Group has a comprehensive small-capacity ROM/low pin count lineup. With USB 2.0 for Battery Charging (BC 1.2), low consumption current, and fast wakeup from standby, these microcontrollers are suitable for use in computer peripherals, and healthcare and wearable devices. With their three-phase motor control timers, they are also suitable for motor control applications in home appliances and industrial equipment.
