Product details
Overview
R5F104JFDFA#V0 from Renesas is a 52-pin LQFP-0.65 mm pitch, industrial-grade (D-grade, −40 to +85°C) 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash. It integrates a 32 MHz RL78 CPU core delivering 44 DMIPS, ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD), 10-bit 16-channel ADC, dual 8-bit DACs, real-time clock, and multiple serial interfaces including UART/LIN, I²C, and CSI.
For engineers reviewing the R5F104JFDFA#V0 datasheet, R5F104JFDFA#V0 pinout, R5F104JFDFA#V0 application, or R5F104JFDFA#V0 equivalent, this MCU targets cost-sensitive, battery-aware industrial control systems requiring integrated analog peripherals, deterministic timing, and robust low-voltage operation down to 1.6 V.
Technical Context
The R5F104JFDFA#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction cycle time (0.03125–30.5 μs). It supports on-chip debug, self-programming with boot swap, and background data flash rewriting (BGO) at 1.8–5.5 V.
Its peripheral set includes Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, watchdog timer, event link controller (ELC) for hardware-triggered peripheral chaining, and data transfer controller (DTC) supporting normal, repeat, and block transfer modes activated by interrupt sources.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F104JFDFA#V0?
The R5F104JFDFA#V0 operates at up to 32 MHz with its RL78 CPU core, achieving 44 DMIPS performance. This benchmark reflects integer instruction throughput under standard test conditions and enables real-time execution of control loops, communication stacks, and signal processing tasks without external acceleration.
Does the R5F104JFDFA#V0 support background data flash rewriting while executing code from main flash?
Yes, the R5F104JFDFA#V0 supports Background Operation (BGO) for data flash. Instructions can be fetched and executed from program flash memory while simultaneously rewriting the 8 KB data flash area, enabling seamless firmware parameter updates or data logging without system interruption.
What are the key low-power modes supported by the R5F104JFDFA#V0 and their typical current consumption?
The R5F104JFDFA#V0 supports HALT, STOP, and SNOOZE modes. HALT draws ~66 μA/MHz; STOP consumes 0.60 μA when only RTC and LVD remain active; SNOOZE allows selected peripherals (e.g., ADC, UART) to operate while CPU sleeps, with current scaling based on enabled functions and clock settings.
How many analog input channels does the 10-bit ADC in the R5F104JFDFA#V0 support, and what reference options are available?
The R5F104JFDFA#V0 integrates a 10-bit successive-approximation ADC with 16 analog input channels. It supports both external reference voltage (applied to AVREFP/AVREFM pins) and internal 1.45 V reference, enabling flexible measurement ranges across varying supply voltages from 1.6 V to 5.5 V.
Is the R5F104JFDFA#V0 pin-compatible with other members of the RL78/G14 family in the same 52-pin LQFP package?
Yes, all RL78/G14 devices in the 52-pin LQFP-0.65 mm package-including R5F104JFDFA#V0, R5F104JGDFA#V0, and R5F104JHDFA#V0-share identical pinouts and electrical characteristics. Firmware and PCB designs are interchangeable across these variants, differing only in flash/RAM capacity and associated memory-mapped resources.
