Product details
Overview
R5F104FDDFP#X0 from Renesas Electronics is a 44-pin LQFP-packaged 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (44 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes, integrated RTC, 10-bit ADC (16 channels), and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104FDDFP#X0 datasheet, R5F104FDDFP#X0 pinout, R5F104FDDFP#X0 application, or R5F104FDDFP#X0 equivalent, key selection criteria include its -40°C to +85°C industrial-grade temperature range (D-suffix), 44-pin 0.8 mm pitch LQFP package, 96 KB code flash with self-programming, and peripheral set optimized for deterministic real-time control with low active and standby current.
Technical Context
The R5F104FDDFP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and includes multiply/divide/accumulate instructions with 1 MB address space. It integrates a Data Transfer Controller (DTC) for autonomous memory transfers triggered by interrupts and an Event Link Controller (ELC) enabling direct hardware linking of 19–26 event sources to peripherals without CPU intervention.
Its power management includes on-chip POR and voltage detector (LVD) with 14 selectable reset/interrupt thresholds, while clocking supports high-accuracy ±1.0% internal oscillator (1–64 MHz) and external crystal (up to 20 MHz). The MCU supports background operation (BGO) during data flash rewriting and provides real-time output capability on its 8-bit D/A converter.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104FDDFP#X0?
The R5F104FDDFP#X0 operates at up to 32 MHz with a measured performance of 44 DMIPS. This value is derived from the RL78 core's 3-stage pipeline and instruction mix benchmarking per EEMBC CoreMark methodology. The high-speed on-chip oscillator supports this frequency with ±1.0% accuracy across 1.8–5.5 V and –40°C to +85°C, eliminating need for external crystal in many applications.
Does the R5F104FDDFP#X0 support in-system programming and secure firmware updates?
Yes, the R5F104FDDFP#X0 supports full in-system programming via on-chip debug interface and includes boot swap functionality plus flash shield window for secure firmware updates. These features allow field-upgradable code without external programmers, and prevent unauthorized read-out or overwrite of protected flash regions - essential for certified industrial deployments.
How many analog input channels does the R5F104FDDFP#X0 ADC support, and what reference options are available?
The R5F104FDDFP#X0 integrates a 10-bit successive-approximation ADC with 16 analog input channels. It supports both external reference voltage and internal 1.45 V reference, enabling stable measurements independent of VDD fluctuations. The ADC also includes an integrated temperature sensor for system-level thermal monitoring.
What power-saving modes are available on the R5F104FDDFP#X0, and what is the lowest achievable current draw?
The R5F104FDDFP#X0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.60 μA typical at 25°C - verified per datasheet R01DS0053EJ0340. This ultra-low quiescent current enables multi-year operation on coin-cell batteries in metering and environmental monitoring applications.
Is the R5F104FDDFP#X0 pin-compatible with other RL78/G14 variants in the same 44-pin LQFP package?
Yes, all RL78/G14 devices in the 44-pin LQFP package (e.g., R5F104FADFP#X0, R5F104FGDFP#X0, R5F104FDDFP#X0) share identical pinout, electrical characteristics, and footprint. This enables drop-in replacement across memory/configurations - verified in Renesas' ordering information tables and package drawings PLQP0044GC-A/GE-A.
