Product details
Overview
R5F104BDGFP#X0 from Renesas is a 32-bit RL78/G14 microcontroller with 48 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (44 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), integrated 10-bit ADC (12-channel), and real-time clock - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104BDGFP#X0 datasheet, R5F104BDGFP#X0 pinout, R5F104BDGFP#X0 application, or R5F104BDGFP#X0 equivalent, key selection criteria include its LFQFP-32 package with 0.5 mm pitch, industrial-grade temperature range (−40°C to +85°C), on-chip debug support, and compatibility with Renesas' CS+ and e² studio toolchains.
Technical Context
The R5F104BDGFP#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), multiply/divide/accumulate instructions, and 1 MB address space. It integrates a high-accuracy ±1.0% on-chip oscillator (selectable from 1–64 MHz) and dual-clock domain operation for independent peripheral timing.
Its power management includes HALT, STOP, and SNOOZE modes, plus an on-chip LVD with 14 selectable voltage thresholds and POR circuitry. Peripheral coordination is handled via Event Link Controller (ELC) supporting 19–26 event sources and Data Transfer Controller (DTC) with chain transfer capability.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F104BDGFP#X0?
The R5F104BDGFP#X0 operates at up to 32 MHz with a measured performance of 44 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, enabling deterministic real-time response in control loops and communication stacks. The R5F104BDGFP#X0 maintains this speed across its full 1.6–5.5 V supply range and −40°C to +85°C temperature envelope.
Does the R5F104BDGFP#X0 support in-system programming and secure firmware updates?
Yes, the R5F104BDGFP#X0 supports full in-system programming via its on-chip debug interface and includes boot swap functionality plus flash shield window protection. These features allow field firmware updates without removing the device, while preventing unauthorized access to protected code regions. The R5F104BDGFP#X0 also enables background data flash writes during program execution for non-disruptive parameter storage.
What analog peripherals are integrated into the R5F104BDGFP#X0 and how many channels do they support?
The R5F104BDGFP#X0 integrates a 10-bit successive-approximation ADC with 12 analog input channels (ANI0–ANI7, ANI16–ANI19), internal 1.45 V reference voltage, and an on-die temperature sensor. It does not include a DAC or comparator in this variant. All ADC channels operate across the full 1.6–5.5 V supply range, supporting ratiometric measurements when paired with AVREFP/AVREFM pins.
Which serial communication interfaces are available on the R5F104BDGFP#X0 and are they hardware-accelerated?
The R5F104BDGFP#X0 provides three UART/LIN channels (with automatic LIN header detection), four I²C interfaces (including simplified I²C), and three CSI modules (SPI-compatible with master/slave support). All are implemented in dedicated hardware with FIFO buffers and independent clock domains - eliminating bit-banging overhead and ensuring deterministic timing for protocols like Modbus RTU or I²C sensor polling.
What is the industrial temperature grade and package type of the R5F104BDGFP#X0?
The R5F104BDGFP#X0 is specified for industrial operation from −40°C to +85°C (D-grade) and housed in a 32-pin LFQFP package with 7 × 7 mm body and 0.5 mm lead pitch. Its ordering code suffix "#X0" indicates embossed tape packaging, and "FP" denotes the LFQFP form factor - compatible with standard reflow profiles and automated assembly lines.
