Resources for RL78/L23
Description
The Renesas RL78/L23 microcontroller has an RL78-S3 CPU core and rich peripheral features to deliver a better design experience that allows high-level system design while reducing power consumption, system cost, and overall footprint through an extensive range of peripheral functions and low-power operation. RL78/L23 is designed to meet the dynamic requirements of human-machine interface (HMI) applications, featuring capabilities such as capacitive touch sensing and segment LCD control. Additionally, HMI application systems can stay up-to-date, since RL78/L23’s dual-bank flash memory enables continuous firmware updating without interrupting system operation. RL78/L23 also supports rich timer functions including 16-bit general-purpose timers, 32-bit and 16-bit low-power inverter timers, 16-bit Timer RJ, 16-bit Timer KB, and RTC. Timer KB can generate up to 3 channels of PWM signals suitable for controlling power supplies, lighting, and inductive heating (IH) control.
The EEMBC (Embedded Microprocessor Benchmark Consortium) benchmark “ULPMark-PP (ULPMark-Peripheral Profile)” has registered the new score of 260 (1.8V) and 154 (3.0V) as the world's highest score for a 16-bit LCD MCU (as of February 21, 2026). ULPMark-PP is an international benchmark for quantitatively evaluating the energy efficiency of peripheral functions integrated within microcontrollers.
