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. The 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 the RL78/L23 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, a 16-bit timer RJ, 16-bit timer KB, and an RTC. Timer KB can generate up to 3 channels of PWM signals suitable for controlling power supplies, lighting, and inductive heating (IH) control.
