Product details
Overview
R5F100MJGFB#V0 from Renesas is a 80-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces - deployed in industrial motor control and sensor-based embedded systems.
For engineers reviewing the R5F100MJGFB#V0 datasheet, R5F100MJGFB#V0 pinout, R5F100MJGFB#V0 application, or R5F100MJGFB#V0 equivalent, key selection criteria include industrial-grade temperature support (−40°C to +105°C), integrated data flash rewrite endurance (1M cycles), low-voltage operation (1.6–5.5 V), and hardware-accelerated multiply-accumulate capability for deterministic control loops.
Technical Context
The R5F100MJGFB#V0 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting configurable instruction timing from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm/correction, 2–4 channel DMA, and three independent serial interface groups (CSI, UART/LIN, I²C) - all accessible via flexible port mapping and interrupt prioritization for deterministic real-time response.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MJGFB#X0 | Identical silicon; differs only in packaging - embossed tape instead of tray | No functional difference; suited for automated SMT assembly requiring tape-and-reel feed | Select #X0 for high-volume production lines using pick-and-place machines with tape feeders |
| R5F101MJGFB#V0 | Omits 8 KB data flash; retains same core, peripherals, package, and temperature grade | Not suitable for applications requiring nonvolatile parameter storage or firmware update logging | Choose when cost reduction is critical and data retention is handled externally or not required |
Compared with R5F100MJGFB#V0, the #X0 variant offers identical electrical and functional behavior with tape packaging for automated placement, while the R5F101MJGFB#V0 removes data flash to lower cost - making it viable only where external EEPROM or no persistent storage is acceptable.

What is the maximum operating frequency and corresponding DMIPS rating for the R5F100MJGFB#V0?
The R5F100MJGFB#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This is achieved using the high-speed on-chip oscillator, which supports ±1.0% accuracy across −20°C to +85°C ambient conditions. The RL78 CPU core's 3-stage pipeline and optimized instruction set deliver consistent throughput for real-time control tasks without requiring external clock sources.
Does the R5F100MJGFB#V0 support true data flash read-while-write (RWW) functionality?
Yes, the R5F100MJGFB#V0 supports background operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously rewriting data flash sectors - enabling seamless firmware parameter updates, event logging, or calibration storage without system interruption or latency spikes.
What is the industrial temperature range certified for the R5F100MJGFB#V0, and how is it indicated in the part number?
The R5F100MJGFB#V0 is rated for −40°C to +105°C operation, denoted by the "G" suffix in the part number (R5F100MJGFB#V0). This G-grade qualification meets industrial application requirements for extended thermal stability in motor drives, PLC modules, and outdoor sensor enclosures where ambient extremes exceed commercial-grade limits.
How many analog input channels does the integrated 10-bit ADC support on the R5F100MJGFB#V0?
The R5F100MJGFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor - both accessible via dedicated ANI pins - enabling accurate voltage, current, and thermal measurements without external references or sensors.
Is the R5F100MJGFB#V0 pin-compatible with other RL78/G13 variants in the same 80-pin LFQFP package?
Yes, all RL78/G13 devices in the 80-pin LFQFP package (e.g., R5F100MJx, R5F101MJx) share identical pinouts and mechanical footprint. Signal mapping, power, and ground pin locations are fixed across the family - allowing hardware reuse across flash/RAM variants and data-flash-enabled vs. disabled versions without PCB redesign.
