Product details
Overview
R5F100MFGFA#10 from Renesas is an RL78/G13 16-bit general-purpose microcontroller with 128 KB flash memory, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces (UART, I²C, CSI). It targets battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100MFGFA#10 datasheet, R5F100MFGFA#10 pinout, R5F100MFGFA#10 application, or R5F100MFGFA#10 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature grade (G suffix), on-chip debug support, self-programmable flash with boot swap, and BGO-capable data flash for concurrent execution and rewriting.
Technical Context
The R5F100MFGFA#10 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting variable instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and a watchdog timer powered by a dedicated low-speed oscillator.
Its peripheral set includes up to 16 channels of 16-bit timers, 2–4-channel DMA, hardware multiplier/divider/MAC, and flexible serial interfaces: 2–4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable via register settings without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MLGFA#10 | Same 80-pin LQFP-0.65mm package, identical 128 KB/8 KB/12 KB memory, but rated for -40°C to +85°C (D-grade) | Not qualified for extended industrial ambient (105°C); suitable for indoor control panels without thermal stress | Select when full G-grade temperature range is unnecessary and cost optimization is prioritized |
| R5F101MFGFA#10 | Same footprint and speed, but lacks data flash memory (0 KB); retains full code flash and peripheral set | Cannot store field-upgradable parameters or logs in nonvolatile memory without external EEPROM | Choose when data logging or over-the-air parameter updates are not required, reducing BOM cost and firmware complexity |
Compared with R5F100MLGFA#10 and R5F101MFGFA#10, the R5F100MFGFA#10 uniquely combines extended temperature operation (+105°C), integrated data flash for robust field updates, and ultra-low-power RTC retention - making it optimal for sealed, battery-backed, thermally demanding edge nodes.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100MFGFA#10?
The R5F100MFGFA#10 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its high-speed on-chip oscillator supports ±1.0% accuracy across 1.8–5.5 V and -40°C to +85°C, and the RL78 core's 3-stage pipeline enables deterministic timing for real-time control loops. This makes the R5F100MFGFA#10 suitable for applications requiring responsive motor control or sensor fusion without external clock sources.
Does the R5F100MFGFA#10 support in-system programming and secure firmware updates?
Yes, the R5F100MFGFA#10 supports full in-system programming via its on-chip debug interface, including self-programming of code flash with boot swap functionality and flash shield window protection. These features enable secure field firmware updates and dual-bank fail-safe upgrades - critical for deployed R5F100MFGFA#10-based devices in inaccessible locations like utility meters or remote sensors.
How many analog input channels does the R5F100MFGFA#10 ADC support, and what reference options are available?
The R5F100MFGFA#10 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external VREFP/VREFM references as well as an internal 1.45 V reference voltage, which is factory-trimmed and temperature-stable. The internal reference allows accurate measurements without external components - a key advantage for compact R5F100MFGFA#10 designs in space-constrained applications.
What low-power modes are available on the R5F100MFGFA#10, and what peripherals remain active in each?
The R5F100MFGFA#10 offers HALT, STOP, and SNOOZE modes. In STOP mode (0.57 μA), only the RTC and LVD remain operational - ideal for calendar-triggered wakeups. HALT mode halts the CPU while preserving RAM and most peripherals. SNOOZE mode allows selected peripherals (e.g., UART, ADC) to operate autonomously while the CPU sleeps, reducing average power in burst-sensing applications using the R5F100MFGFA#10.
Is the R5F100MFGFA#10 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 80-pin LQFP-0.65mm package (e.g., R5F100MFAFA#10, R5F100MLGFA#10) share identical pinouts and electrical characteristics. This allows direct substitution within the same memory/peripheral configuration group - for example, upgrading from 64 KB to 128 KB flash without PCB redesign. However, functional differences (e.g., data flash presence, temperature grade) must be verified per application requirements for the R5F100MFGFA#10.
