Product details
Overview
R5F100GFAFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 10-bit ADC (26 channels), real-time clock, UART/SPI/I²C interfaces, and DMA for industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F100GFAFB#V0 datasheet, R5F100GFAFB#V0 pinout, R5F100GFAFB#V0 application, or R5F100GFAFB#V0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G), 48-pin 7×7 mm 0.5-mm-pitch LFQFP package, integrated data flash with 1M rewrite cycles, and support for SNOOZE mode for low-latency wake-up in energy-constrained designs.
Technical Context
The R5F100GFAFB#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 features dual-clock domains: high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm/correction, 1× hardware multiplier/divider/MAC, and flexible serial interfaces-2–4 UART/LIN, 2–8 CSI (SPI-compatible), and 3–10 I²C channels-all configurable via register-based control without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GGAFA#V0 | Same RL78/G13 core, 48-pin LQFP-0.65 mm pitch (vs. LFQFP-0.5 mm); identical memory and peripherals but larger footprint and lower pin density. | Preferred where PCB rework tolerance or hand-soldering is required; less suitable for space-constrained layouts. | Select when existing LQFP-0.65 mm tooling or legacy board compatibility is prioritized over miniaturization. |
| R5F101GFAFB#V0 | Omits 8 KB data flash; retains same 128 KB code flash, 12 KB RAM, and all peripherals except data flash BGO and self-programming shield functions. | Suitable for cost-sensitive applications where firmware updates occur only via external programmer-not field-upgradable devices. | Choose when data logging, OTA updates, or secure parameter storage are unnecessary, reducing BOM cost by ~12%. |

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100GFAFB#V0?
The R5F100GFAFB#V0 operates at up to 32 MHz with typical active current of 66 μA per MHz at VDD = 3.3 V and TA = 25°C. Its ultra-low-power design achieves 0.57 μA in STOP mode with RTC and LVD enabled, making it ideal for battery-backed applications requiring long-term timekeeping without external supervision.
Does the R5F100GFAFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100GFAFB#V0 supports full in-system programming via its on-chip debug interface and includes boot swap functionality with flash shield window protection. This enables secure, atomic firmware updates in the field-preventing corruption during power loss and blocking unauthorized access to protected code regions.
How many analog input channels does the integrated ADC support, and what reference options are available on the R5F100GFAFB#V0?
The R5F100GFAFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference (AVREFP/AVREFM pins), internal 1.45 V reference (selectable only in HS mode), and VDD as reference-providing flexibility for precision sensor measurement across varying supply conditions.
What low-power modes are available on the R5F100GFAFB#V0, and how quickly can it wake from STOP mode?
The R5F100GFAFB#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode (0.57 μA), wake-up latency is typically 4.2 μs from external interrupt or RTC alarm. SNOOZE mode allows selected peripherals (e.g., UART, ADC) to remain active while CPU sleeps-enabling rapid response without full restart overhead.
Is the R5F100GFAFB#V0 pin-compatible with other RL78/G13 variants in the same package type?
Yes, all RL78/G13 devices in the 48-pin LFQFP-0.5 mm package-including R5F100GFAFB#V0, R5F100GGAFB#V0, and R5F100GHAFB#V0-share identical pinouts and electrical characteristics. Memory and peripheral configurations differ, but PCB layout and signal routing remain fully interchangeable across this package group.
