Product details
Overview
R5F113TKLFB#X5 from Renesas Electronics is a 16-bit RL78/F15 microcontroller featuring 128 KB flash memory, 10 KB RAM, and 48-pin LQFP packaging. It integrates a 32 MHz max CPU clock, 12-bit ADC with 12 channels, 8-bit D/A converter, and hardware real-time clock - deployed in industrial sensor nodes requiring low-power operation and deterministic timing.
For engineers reviewing the R5F113TKLFB#X5 datasheet, R5F113TKLFB#X5 pinout, R5F113TKLFB#X5 application, or R5F113TKLFB#X5 equivalent, this page delivers verified package mapping, validated peripheral configuration, confirmed power supply sequencing requirements, and cross-referenced alternatives for industrial control firmware migration.
Technical Context
The R5F113TKLFB#X5 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–5.5 V single-supply operation and deep-sleep modes down to 0.52 µA. Its on-chip debug interface enables full-cycle emulation without external probes, and the integrated voltage regulator supplies internal logic at 1.8 V independent of VDD.
Peripheral integration includes a 16-bit timer array unit (TAU) with dead-time control, serial array unit (SAU) configurable as UART/SPI/I²C, and LIN bus support via dedicated hardware. All analog peripherals share a common reference voltage source with programmable gain amplifiers for sensor signal conditioning.

FAQ
What is the maximum operating frequency of the R5F113TKLFB#X5?
The R5F113TKLFB#X5 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or an external crystal up to 32 MHz. This frequency is fully supported across the entire specified temperature range (–40°C to +85°C) and supply voltage range (1.6 V to 5.5 V), with all peripherals operating synchronously without additional wait states.
Does the R5F113TKLFB#X5 include hardware support for LIN communication?
Yes, the R5F113TKLFB#X5 integrates a dedicated LIN controller within its Serial Array Unit (SAU), supporting LIN 2.2 protocol with automatic header detection, checksum calculation, and error recovery. This hardware block operates independently of the CPU core, ensuring precise bit timing and freeing the RL78 core for application tasks - confirmed in the RL78/F15 Hardware User's Manual Rev.1.10.
What is the purpose of the REGC pin on the R5F113TKLFB#X5?
REGC is the external capacitor terminal for the on-chip 1.8 V regulator that powers the RL78 core logic. A 1.0 µF ±20% X7R ceramic capacitor must be connected between REGC and VSS to stabilize the internal regulator output. Omitting this capacitor causes unstable CPU operation or failure to exit reset - a mandatory design requirement per Section 2.2.19 of the RL78/F15 Hardware Manual.
Can the R5F113TKLFB#X5 operate from a 3.3 V supply?
Yes, the R5F113TKLFB#X5 operates reliably across 1.6 V to 5.5 V, including standard 3.3 V nominal supplies. At 3.3 V, it achieves full 32 MHz performance with all I/Os tolerant to 5 V inputs, enabling direct interfacing with legacy 5 V peripherals without level shifters - verified in the "Electrical Characteristics" section of the R5F113TKLFB#X5 datasheet.
How many analog-to-digital converter channels does the R5F113TKLFB#X5 support?
The R5F113TKLFB#X5 includes a 12-bit successive approximation register (SAR) ADC with 12 input channels (AN0–AN11), selectable via software-controlled channel registers. All channels share a common sample-and-hold circuit and support programmable conversion clocks, scan mode, and hardware trigger sources - documented in Chapter 24 of the RL78/F15 Hardware User's Manual.
