Mingjiada Electronics one-stop supply (Renesas) RL78/L23 microcontrollers

Source:our siteTime:2025-09-05Views:

Today, with the rapid development of smart home appliances and Internet of Things devices, a high-performance, ultra-low power consumption microcontroller has become the key to product success. Renesas Electronics' newly launched RL78/L23 microcontrollers are injecting new vitality into smart devices with their outstanding energy efficiency and highly integrated features.

Shenzhen Mingjiada Electronics Co., LTD., as a well-known distributor of electronic components, now offers one-stop supply of Renesas' innovative RL78/L23 microcontrollers, providing original factory genuine products and in-stock supply services for customers in the fields of smart home appliances, consumer electronics, Internet of Things and metering systems.

1. Overview

Renesas Electronics' RL78/L23 microcontrollers are equipped with the RL78-S3 CPU core and feature a wealth of peripheral functions, providing a better design experience. This product, while achieving advanced system design, reduces power consumption, system cost and overall space occupation through complete peripheral functions and low-power operation characteristics. The RL78/L23 is specifically designed to meet the flexible requirements of human-machine interface (HMI) application scenarios, featuring capacitive touch sensing and segment LCD control functions. In addition, the RL78/L23 is equipped with dual-zone flash memory, which enables continuous firmware updates without interrupting system operation. Therefore, the HMI application system can always remain up-to-date. Not only that, the RL78/L23 also supports a rich array of timer functions, including 16-bit general-purpose timers, 32-bit and 16-bit low-power flip timers, 16-bit timer RJ, 16-bit timer KB and RTC. Timer KB can generate PWM signals with up to 3 channels and is suitable for power control, lighting and induction heating (IH) control.
