Product details
Overview
R5F104MGGFA#10 from Renesas is a 32-bit RL78/G14 microcontroller with 192 KB flash, 20 KB RAM, and 8 KB data flash, operating at up to 32 MHz (44 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), 48-pin LFQFP package, and industrial-grade temperature range (−40°C to +105°C). It integrates 12-bit ADC (16 channels), UART/SCI/I²C interfaces, RTC, and hardware DTC for sensor control and motor drive applications.
For engineers reviewing the R5F104MGGFA#10 datasheet, R5F104MGGFA#10 pinout, R5F104MGGFA#10 application, or R5F104MGGFA#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch footprint, G-grade industrial temp rating, integrated 12-bit ADC with internal reference, and support for background data flash rewriting during program execution.
Technical Context
The R5F104MGGFA#10 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 uses on-chip high-accuracy oscillator (±1.0% over −20°C to +85°C) and supports HALT/STOP/SNOOZE low-power modes.
Peripheral integration includes Event Link Controller (ELC) for 19–26 event signal routing, Data Transfer Controller (DTC) with chain transfer, Timer Array Unit (TAU) with 8 channels, and Real-time Clock with calendar, alarm, and clock correction - enabling deterministic timing in battery-powered industrial controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LGGB#10 | Same RL78/G14 core, 128 KB flash, 16 KB RAM, 8 KB data flash, identical 48-pin LFQFP-0.5 mm package | Suitable for cost-sensitive designs with reduced code size requirements; same peripheral set and G-grade temp range | Select when firmware fits within 128 KB and BOM cost optimization is prioritized over future scalability |
| R5F104MGGB#10 | Identical 192 KB flash, 20 KB RAM, 8 KB data flash, but rated for −40°C to +85°C (D-grade), not +105°C | Applicable in commercial/industrial environments without extended temperature demands; same pinout and software compatibility | Choose for non-extended-temp applications where qualification to +105°C is unnecessary and D-grade availability is preferred |
Compared with R5F104LGGB#10 and R5F104MGGB#10, the R5F104MGGFA#10 uniquely delivers full 192 KB flash capacity with guaranteed operation up to +105°C in the same 48-pin LFQFP footprint - critical for sealed industrial enclosures and automotive under-hood proximity use cases.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104MGGFA#10?
The R5F104MGGFA#10 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 high-speed on-chip oscillator. The device maintains this performance across its full 1.6 V to 5.5 V supply range and −40°C to +105°C operating temperature, making the R5F104MGGFA#10 suitable for deterministic real-time control tasks in thermally demanding environments.
Does the R5F104MGGFA#10 support background data flash rewriting while executing code from main flash memory?
Yes, the R5F104MGGFA#10 supports Background Operation (BGO) for data flash rewriting. Instructions can be fetched and executed from program flash memory while simultaneously erasing or programming the 8 KB data flash area. This capability enables seamless firmware updates, parameter storage, and logging without system interruption - a confirmed feature documented in the R01DS0053EJ0370 datasheet section 1.1 "Data Flash Memory".
What are the key differences between the G-grade (R5F104MGGFA#10) and D-grade variants of the RL78/G14 family?
The R5F104MGGFA#10 is G-grade, qualified for −40°C to +105°C operation, whereas D-grade variants (e.g., R5F104MGGB#10) are rated only to +85°C. Both share identical peripherals, memory, and pinout. The G-grade undergoes extended temperature screening and packaging validation for harsh industrial environments - critical for applications like enclosed motor drives or outdoor energy infrastructure where ambient temperatures exceed 85°C.
How many analog input channels does the 12-bit ADC in the R5F104MGGFA#10 support, and what reference options are available?
The R5F104MGGFA#10 integrates a 12-bit successive-approximation ADC with 16 analog input channels (P20–P27, plus additional ANI pins). It supports dual reference configurations: external AVREFP/AVREFM differential references or internal 1.45 V bandgap reference. The internal reference enables single-supply operation without external precision voltage sources - a verified specification in the "A/D Converter" section of the R01DS0053EJ0370 datasheet.
Is the R5F104MGGFA#10 pin-compatible with other RL78/G14 devices in the 48-pin LFQFP package?
Yes, all RL78/G14 devices in the 48-pin LFQFP (0.5 mm pitch) package - including R5F104MGGFA#10, R5F104LGGB#10, and R5F104MGGB#10 - share identical pinouts and mechanical footprints. This allows direct hardware reuse across different flash/RAM configurations and temperature grades, provided software is adapted for memory map and peripheral enable differences - confirmed by Renesas' package drawings PLQP0048KF-A and PLQP0048KB-B.
