R7F100LPL3CFB#UA0

R7F100LPL3CFB#UA0 is a RL78/L23 32MHz ultra-low power LCD microcontroller with capacitive touch function. 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.
