Overview
R5F100LEGFB#V0 from Renesas is a 64-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), RTC with calendar/alarm, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LEGFB#V0 datasheet, R5F100LEGFB#V0 pinout, R5F100LEGFB#V0 application, or R5F100LEGFB#V0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), 64-pin LFQFP-0.5mm pitch package (FB), on-chip debug support, self-programmable flash with boot swap, and BGO-capable data flash for concurrent execution and rewriting.
Technical Context

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LEGFB#X0 | Same die, identical electrical specs, but supplied in embossed tape (not tray); same 64-pin LFQFP-0.5mm package | No functional difference; selected for automated SMT line compatibility with tape-and-reel feeders | Choose #X0 for high-volume production; #V0 preferred for prototyping and low-volume builds |
| R5F100LEGLF#V0 | Same flash/RAM/peripherals, but in 64-pin LQFP-0.65mm pitch (PLQP0064JA-A) instead of LFQFP-0.5mm | Larger pad pitch eases manual soldering and rework; slightly larger footprint (12×12 mm vs. 10×10 mm) | Select #V0 in LFQFP for space-constrained designs; choose #V0 in LQFP when layout flexibility or assembly yield is prioritized |
Compared with R5F100LEGFB#V0, the #X0 variant offers identical functionality in tape format for SMT scalability, while the LQFP-packaged R5F100LEGLF#V0 trades compactness for easier assembly - both preserve full RL78/G13 feature set and industrial temperature rating.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for R5F100LEGFB#V0?
The R5F100LEGFB#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 selectable frequencies from 1 MHz to 32 MHz with ±1.0% accuracy across -20°C to +85°C ambient conditions. The RL78 core's 3-stage pipeline and efficient CISC instruction set deliver consistent throughput for real-time control tasks in the R5F100LEGFB#V0.
Does R5F100LEGFB#V0 support background operation during data flash rewriting?
Yes, the R5F100LEGFB#V0 supports Background Operation (BGO) for data flash memory. This allows the CPU to execute instructions from program memory while simultaneously rewriting data flash - critical for seamless firmware updates and parameter storage in live systems. The data flash capacity is 8 KB with a rated endurance of 1,000,000 write cycles at VDD = 1.8–5.5 V, and BGO is enabled by default in standard Renesas flash library configurations for the R5F100LEGFB#V0.
What is the industrial temperature range certified for R5F100LEGFB#V0?
The R5F100LEGFB#V0 is rated for industrial operation from -40°C to +105°C, indicated by the "G" suffix in its part number. This grade is validated per Renesas' qualification standards for extended thermal reliability and is supported across all specified voltage ranges (1.6 V to 5.5 V) and operating modes including HALT, STOP, and SNOOZE. The R5F100LEGFB#V0 maintains full functionality - including RTC, ADC, and serial interfaces - across this full temperature span.
How many analog input channels does the 10-bit ADC in R5F100LEGFB#V0 support?
The R5F100LEGFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), configurable via the ANSEL register. It supports internal reference (1.45 V) and includes an integrated temperature sensor usable for system thermal monitoring. All channels operate across the full 1.6–5.5 V supply range, and conversion results are accessible via dedicated SFRs or DMA transfer - a capability confirmed in the R5F100LEGFB#V0 datasheet section 1.1 Features and Table 1-1 pin mapping.
What debug and programming interfaces are available on R5F100LEGFB#V0?
The R5F100LEGFB#V0 features a full on-chip debug interface compliant with Renesas E1/E20 emulators, accessible via dedicated TOOLx pins (e.g., TOOLRxD on P11). It supports flash self-programming with boot swap and flash shield window functions for secure firmware updates. No external debug probe is required for basic programming or real-time debugging - all capabilities are implemented in silicon and documented in the R5F100LEGFB#V0 hardware manual and Flash Self-Programming Library (R20UT2944).
