Product details
Overview
R5F104FJDFP#X0 from Renesas is a 44-pin LQFP, 96 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104FJDFP#X0 datasheet, R5F104FJDFP#X0 pinout, R5F104FJDFP#X0 application, or R5F104FJDFP#X0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm package, 96 KB code flash with data flash shield window, integrated 10-bit 20-channel ADC, real-time clock with calendar, and support for LIN-bus UART and hardware DTC/ELC peripherals.
Technical Context
The R5F104FJDFP#X0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and includes on-chip debug, self-programming with boot swap, and background operation for data flash rewriting.
It integrates dual-clock domains: high-speed on-chip oscillator (selectable 1–64 MHz, ±1.0% accuracy) and subsystem clock (32.768 kHz), enabling precise RTC operation and low-power STOP/HALT/SNOOZE modes - critical for energy-constrained industrial monitoring systems.

Does the R5F104FJDFP#X0 support LIN bus communication, and how is it implemented?
Yes, the R5F104FJDFP#X0 supports LIN bus communication through its UART peripherals - specifically UART0, UART1, and UART2, all of which include LIN-break-detection and sync-byte handling per LIN 2.x specifications. The R5F104FJDFP#X0 requires no external transceiver for basic LIN node operation when paired with a compliant physical layer driver.
What are the memory resources allocated to the R5F104FJDFP#X0, and how is data flash utilized?
The R5F104FJDFP#X0 includes 96 KB of code flash memory and 8 KB of dedicated data flash memory. Data flash supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for storing calibration data, device configuration, or event logs with 1,000,000 write cycles endurance at 1.8–5.5 V supply.
How does the R5F104FJDFP#X0 achieve ultra-low power consumption in STOP mode?
The R5F104FJDFP#X0 achieves 0.60 μA STOP mode current by retaining only the real-time clock (RTC) and low-voltage detector (LVD) circuits in active state while shutting down the CPU, flash, RAM, and most peripherals. Wake-up is supported via RTC alarm, external interrupt (INTP0–INTP9), or reset - enabling multi-year battery operation in intermittent-sensing applications.
What package type and pin count does the R5F104FJDFP#X0 use, and what are its thermal characteristics?
The R5F104FJDFP#X0 uses a 44-pin LQFP package (10 × 10 mm, 0.8 mm pitch) rated for industrial temperature range (−40°C to +85°C). Its thermal resistance (θJA) is 45°C/W, and it features exposed pad-less construction - compatible with standard reflow profiles and suitable for convection-cooled industrial PCBs without forced airflow.
