Product details
Overview
R5F100MHDFB#V0 from Renesas is an RL78/G13 80-pin LFQFP MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and industrial-grade -40°C to +105°C operation. It integrates a 10-bit ADC (26 channels), RTC, 16-bit timers (12 channels), UART/SCI (4 channels), I²C (3 channels), and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in HVAC, motor drives, and industrial sensors.
For engineers reviewing the R5F100MHDFB#V0 datasheet, R5F100MHDFB#V0 pinout, R5F100MHDFB#V0 application, or R5F100MHDFB#V0 equivalent, key selection criteria include its 80-pin LFQFP-0.5mm package, integrated data flash with background operation, real-time clock with calendar function, and support for LIN-bus via UART peripherals - all critical for deterministic, low-power industrial firmware deployment.
Technical Context
The R5F100MHDFB#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports multiple low-power states including HALT, STOP, and SNOOZE modes, enabling dynamic power scaling across operational phases.
Its peripheral set includes dual DMA controllers (4 channels), hardware multiplier/divider/MAC, on-chip high-accuracy oscillator (±1.0% over VDD = 1.8–5.5 V), and voltage detector with 14-level LVD interrupt/reset selection - all designed for robust, self-contained operation without external timing or supervision components.

FAQ
What is the maximum operating frequency of the R5F100MHDFB#V0?
The R5F100MHDFB#V0 supports a maximum CPU clock frequency of 32 MHz using the on-chip high-speed oscillator. This delivers 41 DMIPS performance and enables sub-microsecond interrupt latency for time-critical control tasks. The oscillator maintains ±1.0% accuracy across VDD = 1.8–5.5 V and TA = –20 to +85°C, eliminating need for external crystals in many applications.
Does the R5F100MHDFB#V0 include integrated data flash memory?
Yes, the R5F100MHDFB#V0 includes 8 KB of on-chip data flash memory. It supports background operation (BGO), allowing the CPU to execute code from program memory while simultaneously rewriting data flash. Rated for 1,000,000 write/erase cycles at VDD = 1.8–5.5 V, it serves as reliable nonvolatile storage for calibration data, device configuration, and event logs without external EEPROM.
What low-power modes does the R5F100MHDFB#V0 support?
The R5F100MHDFB#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - ideal for battery-powered wake-on-event applications. HALT mode reduces current to 66 μA/MHz during active operation, and SNOOZE enables selective peripheral wake-up without full CPU restart, optimizing energy use in sensor polling routines.
Is the R5F100MHDFB#V0 pin-compatible with other RL78/G13 variants?
Yes, the R5F100MHDFB#V0 is pin-compatible with all 80-pin LFQFP variants in the RL78/G13 family, including R5F100MLDFB#V0 (512 KB flash), R5F101MHDFB#V0 (no data flash), and R5F100MHAFB#V0 (same flash/RAM, different temp grade). Pinouts, peripheral mappings, and electrical characteristics are identical - enabling hardware reuse across performance and memory variants.
What development tools support the R5F100MHDFB#V0?
The R5F100MHDFB#V0 is fully supported by Renesas e² studio IDE, CS+ (formerly CubeSuite+), and the Renesas Flash Programmer. Hardware debugging uses E2 emulator Lite or E2 emulator, both compatible with the 80-pin LFQFP footprint. Example projects, HAL drivers, and RL78/G13-specific BSPs are available in the Renesas GitHub repository and Synergy Gallery.
