Overview

Description

The RL78/G15 is a general-purpose microcontroller with a 16MHz operating frequency. There is a wide lineup available, including the smallest 8-pin package in the RL78 Family, and support for a wide range of operating ambient temperatures from -40°C to 125°C. The built-in high-speed on-chip oscillator with high accuracy (±1.0%), the data flash, the rich serial interfaces, and the comparator make it ideal for compact applications where space comes at a premium. A full development environment for the RL78/G15 is provided, including an evaluation board (Fast Prototyping Board) enabling writing and debugging programs by simply connecting a USB cable, a Smart Configurator that facilitates software design with GUI, and an Arduino library. Moreover, it is compatible with the existing RL78 Family and can be used in a wide range of applications, from home appliances and consumer electronics to industrial equipment.
