Overview

Description

The RL78/G16 microcontroller is a general-purpose microcontroller with capacitive touch channels and a 16 MHz operating frequency. There is a broad lineup of touch microcontrollers available, including Renesas' smallest 10-pin package. It is also equipped with functional safety-compliant hardware to support the acquisition of IEC/UL60730 certification, the safety standard for home appliances. In addition, it has a high precision (±1.0%) high-speed on-chip oscillator, data flash, a rich serial interface, and a comparator built in, making it ideal for compact applications that need space savings. The RL78/G16 development environment is available and includes an evaluation board (Fast Prototyping Board) which enables writing/debugging of programs without additional tools simply by connecting a USB cable, a Smart Configurator which facilitates design with GUI, a capacitive touch evaluation system (evaluation board and QE for Capacitive Touch, a development support tool for capacitive touch sensors), and an Arduino library, etc. It is also compatible with the existing RL78 Family and can be a seamless replacement, making it suitable for a wide range of applications from home appliances and consumer electronics to industrial equipment.
