Product details
Overview
R5F100MHDFB#X0 from Renesas is a 80-pin LFQFP (12 × 12 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash memory, 8 KB data flash, 12 KB RAM, and operation from −40°C to +105°C. It delivers 41 DMIPS at 32 MHz, consumes only 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and targets battery-powered industrial control, sensor nodes, and smart actuators.
For engineers reviewing the R5F100MHDFB#X0 datasheet, R5F100MHDFB#X0 pinout, R5F100MHDFB#X0 application, or R5F100MHDFB#X0 equivalent, key selection criteria include its ultra-low-power STOP/HALT/SNOOZE modes, integrated 10-bit 26-channel ADC with temperature sensor, real-time clock with calendar/alarm, and dual UART/LIN support for robust serial communication in harsh environments.
Technical Context
The R5F100MHDFB#X0 implements the RL78 CPU core with CISC architecture and 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 integrates a 2-channel DMA controller enabling 2-clock transfers between SFR and RAM, and a 16×16-bit multiplier with 32-bit accumulate capability for efficient signal processing.
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, one real-time clock with 99-year calendar and clock correction, and three I²C/Simplified I²C interfaces - all configurable via on-chip registers without external components. The MCU supports background operation (BGO) for data flash rewriting while executing code from program memory.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MHGFB#X0 | Same package, pinout, and memory configuration but rated for −40°C to +105°C with G-grade qualification and enhanced ESD/latch-up immunity | Required for extended-temperature industrial deployments where ambient exceeds +85°C or reliability under thermal stress is critical | Select when full AEC-Q100 Grade 2 or extended industrial qualification is mandated; otherwise R5F100MHDFB#X0 suffices for standard industrial use |
| R5F101MHDFB#X0 | Identical package and pinout but lacks data flash memory (0 KB vs. 8 KB); same 128 KB code flash and 12 KB RAM | Suitable for applications that store configuration in external EEPROM or do not require field-upgradable parameters | Choose to reduce BOM cost where data logging, calibration storage, or secure parameter retention is unnecessary |
Compared with R5F100MHGFB#X0, the R5F100MHDFB#X0 offers identical functionality at lower qualification cost, while R5F101MHDFB#X0 removes data flash to cut cost and simplify firmware architecture - enabling trade-offs between nonvolatile parameter storage, thermal robustness, and unit price.

What communication interfaces does the R5F100MHDFB#X0 support for industrial connectivity?
The R5F100MHDFB#X0 supports multiple industrial-grade interfaces: two UART/LIN modules (with hardware LIN protocol support), up to three I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) interfaces. These enable robust communication with sensors, displays, transceivers, and backplane peripherals without external protocol translators in the R5F100MHDFB#X0 design.
How does the R5F100MHDFB#X0 achieve ultra-low power consumption in standby modes?
The R5F100MHDFB#X0 achieves 0.57 μA in STOP mode by powering down the CPU, flash, and most peripherals while retaining RTC operation, LVD monitoring, and RAM contents. Its HALT and SNOOZE modes provide intermediate power states with selectable peripheral clocks and wake-up sources - enabling flexible energy management strategies in battery-powered R5F100MHDFB#X0 applications.
Is the R5F100MHDFB#X0 pin-compatible with other RL78/G13 variants in the same package?
