Description

The RL78/G22 microcontroller features the industry's lowest current consumption levels of 37.5µA/MHz during CPU operation and 200nA during STOP, as well as a rich array of capacitive touch channels.

The RL78/G22 microcontroller supports a maximum operating frequency of 32MHz, a wide operating voltage range of 1.6V to 5.5V, and enhanced analog and security functions. In addition, the SNOOZE mode sequencer significantly reduces power consumption during intermittent operation. A rich development environment is provided for the RL78/G22 including an evaluation board (Fast Prototyping Board) that enables program writing/debugging without additional tools, simply by connecting a USB cable, and a Smart Configurator that facilitates design using a GUI. 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.

The EEMBC (Embedded Microprocessor Benchmark Consortium) benchmark “ULPMark-PP (ULPMark-Peripheral Profile)” has registered the new score of 330 (1.8V) and 190 (3.0V) as the world's highest score for a microcontroller (as of September 10, 2025). ULPMark-PP is an international benchmark for quantitatively evaluating the energy efficiency of peripheral functions integrated within microcontrollers.
