Overview
R5F100GFGFB#V0 from Renesas is a 48-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, and multiple serial interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GFGFB#V0 datasheet, R5F100GFGFB#V0 pinout, R5F100GFGFB#V0 application, or R5F100GFGFB#V0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), LFQFP-48 package (0.5 mm pitch), on-chip debug support, self-programmable flash with boot swap, and BGO-enabled data flash rewriting during program execution.
Technical Context
The R5F100GFGFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 16 channels of 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible) channels, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM - all optimized for deterministic real-time control in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GGFBS#V0 | Same 48-pin LFQFP package, identical 128 KB flash/8 KB data flash/12 KB RAM, but rated for -40°C to +85°C (D-grade) instead of +105°C. | Suitable for commercial/industrial equipment not exposed to extreme ambient heat (e.g., office appliances, indoor HMI panels). | Select when full industrial temperature range is unnecessary and cost optimization is prioritized. |
| R5F101GFGFB#V0 | Pin-compatible 48-pin LFQFP variant with no data flash (0 KB), same 128 KB code flash and 12 KB RAM, otherwise identical peripherals and power specs. | Applicable where parameter storage is handled externally (e.g., EEPROM or cloud sync), reducing flash wear concerns and BOM complexity. | Choose when data logging or field updates are managed outside MCU, enabling simpler firmware architecture and lower unit cost. |
Compared with R5F100GFGFB#V0, R5F100GGFBS#V0 trades extended temperature capability for lower cost in benign environments, while R5F101GFGFB#V0 removes data flash to simplify qualification and reduce die size - both retain identical pinout, code flash, RAM, and peripheral sets for seamless migration.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GFGFB#V0?
The R5F100GFGFB#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS (Dhrystone 2.1). This rating reflects sustained integer compute throughput under typical code mix conditions, validated per Renesas test methodology in R01DS0131EJ0380 Rev.3.80 Section 2.2. The high-speed on-chip oscillator supports this frequency without external crystals, reducing system BOM.
Does the R5F100GFGFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100GFGFB#V0 supports full in-system programming via its on-chip debug interface and self-programming flash controller. It implements boot swap functionality and flash shield window protection to prevent unauthorized access during firmware updates - critical for secure over-the-air (OTA) deployment in fielded R5F100GFGFB#V0-based devices.
What are the key low-power modes available on the R5F100GFGFB#V0 and their typical current consumption?
The R5F100GFGFB#V0 offers HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC + LVD active), and SNOOZE mode (selective peripheral wake-up). These values are measured at VDD = 3.3 V, TA = 25°C per R01DS0131EJ0380 Section 1.1. The STOP mode current enables multi-year operation on coin-cell batteries when paired with infrequent RTC-triggered wake-ups.
How many analog input channels does the integrated ADC support, and what reference options are available for the R5F100GFGFB#V0?
The R5F100GFGFB#V0 features a 10-bit successive-approximation ADC with up to 26 analog input channels. Reference options include external AVREFP/AVREFM pins or internal 1.45 V bandgap reference - selectable per channel via register configuration. The internal reference is factory-trimmed and stable across temperature, enabling accurate ratiometric sensing without external components.
Is the R5F100GFGFB#V0 pin-compatible with other RL78/G13 variants in the same 48-pin LFQFP package?
Yes, all RL78/G13 devices in the 48-pin LFQFP package (e.g., R5F100GxxFB#V0, R5F101GxxFB#V0) share identical pinouts and mechanical dimensions. This allows direct substitution between variants differing only in flash type (data flash presence), memory size, or temperature grade - provided firmware and power sequencing align with the target device's specifications.
