It targets low-power industrial control and sensor interface applications requiring integrated analog peripherals and robust code protection.
For engineers reviewing the R5F113LKCLFB#15 datasheet, R5F113LKCLFB#15 pinout, R5F113LKCLFB#15 application, or R5F113LKCLFB#15 equivalent, this page delivers verified package mapping (LQFP-64), confirmed peripheral set (ADC, RTC, UART, I²C, LIN), and validated alternative options for migration or second-sourcing in embedded control designs.
Technical Context
The R5F113LKCLFB#15 implements the RL78 CPU core with 3-stage pipeline and CISC architecture optimized for ultra-low power operation. It includes on-chip debug functionality, 16-level priority interrupt controller, and dual voltage domains (core @ 1.8 V, I/O @ 1.6–5.5 V) enabling flexible system integration.
