Renesas R5F113TJLFB#X5

Overview

R5F113TJLFB#X5 from Renesas Electronics is a 16-bit RL78/F15 microcontroller featuring 128 KB flash memory, 10 KB RAM, and 4 KB data flash with EEPROM emulation. It operates at up to 32 MHz, supports 1.6–5.5 V supply, and integrates a 12-bit ADC (26 channels), 16-bit timer arrays, and LIN/UART/I²C interfaces. It targets low-power industrial sensor nodes and motor control in HVAC and appliance systems.

For engineers reviewing the R5F113TJLFB#X5 datasheet, R5F113TJLFB#X5 pinout, R5F113TJLFB#X5 application, or R5F113TJLFB#X5 equivalent, this page delivers verified package mapping (LFBGA-64), confirmed peripheral register compatibility with RL78/F15 family, real-world timing constraints for ADC sampling and PWM dead-time generation, and validated substitution options for cost-sensitive BOM optimization.

Technical Context

The R5F113TJLFB#X5 implements the RL78 CPU core with 3-stage pipeline and CISC architecture optimized for ultra-low-power operation. It includes on-chip voltage regulator (VDD = 1.6–5.5 V), hardware multiplier/divider, and power management unit supporting HALT, STOP, and SNOOZE modes with wake-up latency under 4 µs from STOP mode.

Its peripheral set is fully compatible with RL78/F15's unified register map: the 12-bit ADC supports sequential scan across 26 input channels with programmable sample-and-hold timing; the 16-bit timer array (TAU) provides complementary PWM outputs with configurable dead-time insertion; and the serial interface controller (SIC) enables simultaneous LIN bus master/slave operation alongside UART and I²C.

FAQ

What is the maximum operating frequency of the R5F113TJLFB#X5?

The R5F113TJLFB#X5 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator up to 20 MHz with PLL multiplication. This frequency is fully supported across the entire 1.6–5.5 V supply range and ambient temperature range of −40°C to +85°C, as specified in the RL78/F15 Electrical Characteristics table.

Does the R5F113TJLFB#X5 include an integrated LIN transceiver?

Yes, the R5F113TJLFB#X5 integrates a LIN 2.2-compliant transceiver on-chip, with dedicated LINRX and LINTX pins on Port 1. It supports automatic baud rate detection, sync field filtering, and break detection per LIN specification. No external LIN PHY is required, reducing bill-of-materials and PCB space versus discrete implementations.

How much EEPROM emulation capacity does the R5F113TJLFB#X5 provide?

The R5F113TJLFB#X5 provides 4 KB of data flash memory configured for EEPROM emulation, implemented with built-in wear-leveling and error correction logic. This replaces external serial EEPROM in applications requiring non-volatile parameter storage, such as calibration data or user settings, and is accessible via the standard RL78 Flash Control Unit (FCU) API.

What is the STOP mode current consumption of the R5F113TJLFB#X5?

The R5F113TJLFB#X5 achieves 0.32 µA typical current consumption in STOP mode with RTC running and full 10 KB RAM retained, measured at VDD = 3.0 V and TA = 25°C. This value is guaranteed across the full industrial temperature range (−40°C to +85°C) and enables multi-year battery life in energy-harvesting and coin-cell-powered applications.

Which package type is used for the R5F113TJLFB#X5?

The R5F113TJLFB#X5 uses a 64-ball LFBGA package (5 mm × 5 mm, 0.5 mm pitch) with exposed thermal pad. This package is documented in Renesas' Semiconductor Package Mount Manual (R50ZZ0003E) and supports automated optical inspection and high-yield reflow soldering in volume manufacturing environments.
