Product details
Overview
R5F100MHGFA#10 from Renesas is an RL78/G13 80-pin LQFP 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 16-bit timers, 10-bit ADC (26 channels), RTC, UART/I²C/CSI interfaces, 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 R5F100MHGFA#10 datasheet, R5F100MHGFA#10 pinout, R5F100MHGFA#10 application, or R5F100MHGFA#10 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, integrated data flash with 1M rewrite cycles, real-time clock with calendar/alarm, and support for LIN-bus via UART - all validated for high-reliability industrial environments.
Technical Context
The R5F100MHGFA#10 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It features dual-voltage operation (1.6–5.5 V), on-chip POR/LVD, and background operation for data flash rewriting while executing code from program memory.
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, one real-time clock with calendar and clock correction, and a watchdog timer driven by dedicated low-speed oscillator - enabling deterministic timing and fail-safe behavior in safety-critical control loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MHGFB#10 | Same core, memory, and peripherals; differs only in package - LFQFP (0.5-mm pitch) vs. LQFP (0.65-mm pitch) | Requires PCB redesign due to finer pitch and different land pattern; suited for higher-density layouts | Select when board space constraints necessitate smaller footprint and assembly supports 0.5-mm pitch |
| R5F101MHGFA#10 | Omits 8 KB data flash; retains same code flash, RAM, peripherals, and package | Not suitable for applications requiring nonvolatile parameter storage or firmware-over-the-air logging | Choose for cost-sensitive designs where data flash is unnecessary and BGO functionality is not required |
Compared with R5F100MHGFA#10, R5F100MHGFB#10 offers identical functionality in a denser package requiring tighter layout tolerances, while R5F101MHGFA#10 reduces cost by removing data flash - making it viable only where persistent parameter storage is handled externally.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100MHGFA#10?
The R5F100MHGFA#10 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 μs in this mode, enabling responsive real-time control for motor drives and sensor fusion applications. The oscillator maintains ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C ambient conditions.
Does the R5F100MHGFA#10 support in-system programming and secure firmware updates?
Yes, the R5F100MHGFA#10 supports full in-system programming via its on-chip debug interface and self-programming capability. It includes boot swap functionality and flash shield window protection to prevent unauthorized access or overwrite of critical bootloader sections. These features allow safe, field-upgradable firmware with rollback capability - essential for industrial equipment with long service lifetimes.
How many analog input channels does the R5F100MHGFA#10 support, and what ADC resolution is available?
The R5F100MHGFA#10 integrates a 10-bit successive approximation ADC with up to 26 analog input channels. It supports both single-ended and differential modes, includes an internal 1.45 V reference voltage, and features an integrated temperature sensor. This configuration enables simultaneous monitoring of multiple sensors - such as thermistors, pressure transducers, and current shunts - without external signal conditioning.
What low-power modes are available on the R5F100MHGFA#10, and what is the lowest achievable current draw?
The R5F100MHGFA#10 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock and low-voltage detector active, it draws just 0.57 μA - verified at VDD = 3.0 V and TA = 25°C. This enables multi-year battery operation in intermittent-sensing applications like environmental monitors or predictive maintenance nodes.
Is the R5F100MHGFA#10 qualified for industrial temperature operation, and what is its rated range?
Yes, the R5F100MHGFA#10 carries the 'G' suffix indicating industrial-grade qualification, with a guaranteed operating ambient temperature range of -40°C to +105°C. This rating is fully specified across all electrical parameters in the datasheet, including flash endurance, ADC accuracy, and oscillator stability - making it suitable for under-hood automotive modules, factory-floor controllers, and outdoor infrastructure equipment.
