Product details
Overview
R5F104BDDFP#V0 from Renesas Electronics is a 32-bit RL78/G14 microcontroller with 48 KB flash, 4 KB data flash, and 5.5 KB RAM, operating at up to 32 MHz (44 DMIPS), supporting ultra-low-power modes (66 μA/MHz active, 0.60 μA RTC+LVD), and targeting industrial control, sensor nodes, and battery-powered HMI interfaces.
For engineers reviewing the R5F104BDDFP#V0 datasheet, R5F104BDDFP#V0 pinout, R5F104BDDFP#V0 application, or R5F104BDDFP#V0 equivalent, this page delivers verified electrical specs, LQFP-32 package details, real-time clock integration, 10-bit ADC with 12-channel analog input, and UART/SPI/I²C interface mapping for rapid embedded system integration.
Technical Context
The R5F104BDDFP#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a 12-bit interval timer, calendar-mode real-time clock with alarm and correction, and watchdog timer driven by dedicated low-speed oscillator.
Peripheral subsystems include Data Transfer Controller (DTC) with chain transfer, Event Link Controller (ELC) linking 19–26 event sources to peripherals, and dual-voltage operation (1.6–5.5 V) enabling direct interfacing with 1.8/2.5/3.0 V logic without level shifters.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104BDDFP#V0?
The R5F104BDDFP#V0 operates at up to 32 MHz with a measured performance of 44 DMIPS. This is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V supply and −20 to +85°C ambient - eliminating need for external crystal in cost-sensitive designs.
Does the R5F104BDDFP#V0 support background data flash rewriting while executing code from main flash?
Yes, the R5F104BDDFP#V0 supports Background Operation (BGO) for data flash. Instructions can be fetched and executed from code flash memory during data flash erase/write cycles, enabling seamless parameter updates without halting real-time control tasks.
What are the analog input capabilities of the R5F104BDDFP#V0, including channel count and resolution?
The R5F104BDDFP#V0 integrates a 10-bit successive-approximation ADC with up to 12 analog input channels, internal 1.45 V reference voltage, and integrated temperature sensor. It supports single-ended and differential input configurations, with conversion times as low as 1.2 μs per sample.
How does the R5F104BDDFP#V0 handle low-power operation, and what is its minimum current draw in retention mode?
The R5F104BDDFP#V0 achieves 0.60 μA in STOP mode with only RTC and LVD active - the lowest power state retaining timekeeping and voltage monitoring. This mode uses the 32.768 kHz subsystem clock and requires no external components beyond the mandatory REGC capacitor.
Is the R5F104BDDFP#V0 pin-compatible with other RL78/G14 variants in the same LQFP-32 package?
Yes, all RL78/G14 devices in the LQFP-32 package (e.g., R5F104BEAFP#V0, R5F104BDGFP#V0) share identical pinouts and electrical characteristics. Firmware and PCB layouts are interchangeable across memory and temperature grade variants - only flash content and qualification differ.
