Product details
Overview
R5F104MHDFB#10 from Renesas is a 80-pin LFQFP, 0.5 mm pitch, industrial-grade (TA = −40 to +105°C) RL78/G14 16-bit MCU with 128 KB flash, 8 KB data flash, 16 KB RAM, 32 MHz max CPU speed (44 DMIPS), and ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode). It integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (16 ch), RTC, and on-chip debug.
For engineers reviewing the R5F104MHDFB#10 datasheet, R5F104MHDFB#10 pinout, R5F104MHDFB#10 application, or R5F104MHDFB#10 equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options for industrial control, sensor hubs, and low-power HMI designs.
Technical Context
The R5F104MHDFB#10 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). It features event-driven peripheral control via ELC (26 event sources) and autonomous data movement via DTC with chain transfer capability.
Its mixed-signal integration includes a 10-bit ADC with internal 1.45 V reference and temperature sensor, dual-channel 8-bit DAC with real-time output, and two comparators with window/low-speed/high-speed modes - all operating across 1.6–5.5 V supply range and qualified for industrial ambient (−40 to +105°C).

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104MHDFB#10?
The R5F104MHDFB#10 achieves a maximum CPU frequency of 32 MHz using the high-speed on-chip oscillator, delivering 44 DMIPS performance. This is confirmed in the RL78/G14 datasheet (R01DS0053EJ0370, p.1) under "True low-power platform… 44 DMIPS at 32 MHz". The core's 3-stage pipeline and optimized instruction set enable deterministic timing critical for real-time control loops in the R5F104MHDFB#10.
Does the R5F104MHDFB#10 support background data flash rewriting while executing application code?
Yes, the R5F104MHDFB#10 supports Background Operation (BGO) for data flash, allowing instruction execution from program memory during data flash erase/write sequences. As specified in the datasheet (R01DS0053EJ0370, p.1), this enables seamless firmware updates and parameter logging without halting real-time tasks - a key capability confirmed for all RL78/G14 devices including the R5F104MHDFB#10.
What are the supported crystal configurations for RTC and main system clock on the R5F104MHDFB#10?
The R5F104MHDFB#10 supports dual crystal configurations: P121/P122 accept a 32.768 kHz crystal for RTC operation, while P123/P124 support a separate high-frequency crystal (e.g., 4–20 MHz) for the main system clock. This separation is documented in the pin configuration section (R01DS0053EJ0370, pp.7–8) and ensures accurate timekeeping independent of CPU clock stability in the R5F104MHDFB#10.
How many analog input channels does the 10-bit ADC in the R5F104MHDFB#10 support, and what reference options are available?
The R5F104MHDFB#10 integrates a 10-bit successive-approximation ADC with up to 16 analog input channels, as listed in the "A/D Converter" feature table (R01DS0053EJ0370, p.1). It supports both external reference voltage and internal 1.45 V reference, enabling precise measurements independent of VDD fluctuations - a confirmed specification for the R5F104MHDFB#10 across its industrial temperature range.
Is the R5F104MHDFB#10 pin-compatible with other RL78/G14 variants in the same 80-pin LFQFP package?
Yes, all RL78/G14 devices in the 80-pin LFQFP package - including R5F104MHDFB#10, R5F104MGDFB#10, and R5F104MHGFB#10 - share identical pinouts and electrical characteristics per the datasheet (R01DS0053EJ0370, p.7). This allows direct substitution within the same package family, provided flash/RAM requirements and temperature grade align with the target application's needs for the R5F104MHDFB#10.
