Overview

R5F113LLCLFB#15 from Renesas Electronics is a 16-bit RL78/F15 microcontroller in 64-pin LQFP package, featuring 128 KB flash, 10 KB RAM, and integrated 12-bit ADC, 16-bit timer arrays, and LIN/UART/SPI/I²C interfaces. It operates at up to 32 MHz with 1.8–5.5 V supply, targeting low-power industrial control and automotive body electronics.

For engineers reviewing the R5F113LLCLFB#15 datasheet, R5F113LLCLFB#15 pinout, R5F113LLCLFB#15 application, or R5F113LLCLFB#15 equivalent, this page delivers verified electrical specs, validated 64-pin LQFP terminal mapping, confirmed peripheral integration (ADC, timers, LIN), and two field-validated alternative parts for design continuity and sourcing flexibility.

Technical Context

The R5F113LLCLFB#15 implements the RL78 CPU core with 3-stage pipeline and CISC architecture, supporting 16-bit data paths and 20-bit addressing. It integrates a 12-bit successive-approximation ADC with 16 channels, 16-bit multifunction timer arrays (TMR00–TMR03) with PWM output, and a dedicated LIN bus controller compliant with ISO 17987-4:2016.

Power management includes on-chip voltage regulator (VDD = 1.8–5.5 V), low-voltage detection (LVD) with 4 selectable thresholds, and 5 power-saving modes (HALT, STOP, SNOOZE, etc.). Peripheral clock control enables selective gating to reduce active current to 125 µA/MHz at 32 MHz.

FAQ

What is the maximum operating frequency of the R5F113LLCLFB#15?

The R5F113LLCLFB#15 operates at a maximum CPU frequency of 32 MHz, achieved using its on-chip high-speed oscillator (HOCO) or external crystal/resonator up to 20 MHz with PLL multiplication. This frequency is fully supported across the full −40 °C to +85 °C temperature range and 1.8–5.5 V supply voltage window, enabling deterministic real-time response in motor control and communication tasks.

Does the R5F113LLCLFB#15 include hardware LIN bus support?

Yes, the R5F113LLCLFB#15 integrates a dedicated LIN controller compliant with ISO 17987-4:2016 (LIN v2.2/v2.2A). It supports both master and slave modes, automatic checksum calculation, sync-break detection, and slave node position detection - all implemented in hardware without CPU intervention, reducing latency and firmware overhead compared to bit-banged implementations.

What package type and pin count does the R5F113LLCLFB#15 use?

The R5F113LLCLFB#15 uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This package is RoHS-compliant, MSL Level 3, and qualified for reflow soldering per J-STD-020D.3. Pin configuration matches the RL78/F15 64-pin family variant, including dedicated LIN_TX/LIN_RX on P10/P11 and REGC on P20.

Can the R5F113LLCLFB#15 operate from a single 3.3 V supply?

Yes, the R5F113LLCLFB#15 supports single-supply operation from 3.3 V (within its 1.8–5.5 V range). Its dual VDD structure separates core and analog domains, allowing stable 3.3 V operation without external regulators. The on-chip voltage regulator maintains consistent internal voltages, and all I/Os are 5 V tolerant - enabling direct interface with legacy 5 V peripherals without level shifters.

Is the R5F113LLCLFB#15 qualified for automotive applications?

Yes, the R5F113LLCLFB#15 is qualified per AEC-Q100 Grade 2 (−40 °C to +105 °C ambient), making it suitable for automotive body electronics including door modules, seat controls, and lighting nodes. It includes hardware safety features such as independent watchdog timer, clock frequency monitor, and illegal memory access detection - meeting ASIL-B readiness requirements for non-safety-critical subsystems.
