Overview

The RL78/G23 microcontroller group is a new generation of the RL78 family of microcontrollers, with 41μA/MHz CPU operation. The RL78/G23 group has the industry’s lowest power consumption with 210nA at stop (4KB SRAM retention), and a snooze mode sequencer which significantly reduces power consumption during intermittent operation. The RL78/G23 group features a wide operating voltage range of 1.6V to 5.5V at up to 32MHz, a broad range of package pin counts from 30 pins to 128 pins, and up to 768KB of flash memory. In addition to enhanced analog and security features, it also incorporates logic and event link controllers (ELCL) and the first capacitive touch sensing unit (CTSU2L) in the RL78 family. A rich development environment is also provided for the RL78/G23, including a fast prototyping board. This board allows users to write and debug programs with an easy-to-use GUI, by simply connecting a USB cable and a smart configurator without any additional tools required. The RL78/G23 is compatible with the existing RL78 family and can be a seamless replacement, making it suitable for a wide range of applications, from home appliance and consumer electronics to industrial equipment.
