Overview
R5F113THLFB#X0 from Renesas Electronics is a 16-bit RL78/F15 microcontroller with 128 KB flash, 10 KB RAM, and 48-pin LQFP package. It integrates a 32 MHz max CPU clock, 12-bit ADC (24 channels), 8-bit D/A converter, 16-bit timer arrays, and LIN/UART/I²C interfaces. It targets automotive body electronics and industrial control where low power and functional safety support are required.
For engineers reviewing the R5F113THLFB#X0 datasheet, R5F113THLFB#X0 pinout, R5F113THLFB#X0 application, or R5F113THLFB#X0 equivalent, this page delivers verified electrical specs, validated pin functions for the 48-pin LQFP variant, confirmed peripheral integration (including LIN v2.2A compliance), and real-world substitution guidance aligned with Renesas' official product lineup documentation.
Technical Context
The R5F113THLFB#X0 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–5.5 V operation and ultra-low-power modes (HALT, STOP, SNOOZE) down to 0.52 µA in STOP mode. Its on-chip debug interface enables full-cycle emulation without external probes.
It features dual voltage domains: EVDD0/EVSS0 for analog peripherals (ADC, D/A, comparator) and VDD/VSS for digital logic-enabling independent noise isolation and precision analog measurement. The integrated LIN controller supports automatic header detection and checksum verification per ISO 17987-4.
