Product details
Overview
R5F100GAGFB#X0 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), real-time clock, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GAGFB#X0 datasheet, R5F100GAGFB#X0 pinout, R5F100GAGFB#X0 application, or R5F100GAGFB#X0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature rating (G-grade), 48-pin LFQFP-0.5mm pitch package, on-chip debug support, and BGO-capable data flash for background reprogramming in field-upgradable embedded systems.
Technical Context
The R5F100GAGFB#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz) and 1 MB address space. 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, 16×16→32-bit multiplier, and 3–10-channel I²C/Simplified I²C - all optimized for deterministic real-time control in resource-constrained industrial edge devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GGGFB#X0 | Same 48-pin LFQFP package, identical 128 KB flash/8 KB data flash/12 KB RAM, but G-grade (-40°C to +105°C) with enhanced ESD tolerance (±4 kV HBM) | Targeted for higher-reliability industrial deployments requiring extended temperature margin and robustness against board-level ESD events | Select when operating near thermal limits or in electrically noisy factory-floor environments where ESD immunity is critical |
| R5F101GAGFB#X0 | Pin-compatible 48-pin LFQFP variant with same memory and peripherals, but lacks data flash (no 8 KB data flash, only code flash) | Suitable for cost-sensitive applications where firmware updates are infrequent and parameter storage is handled externally | Choose when eliminating data flash reduces BOM cost and security requirements do not mandate on-chip nonvolatile parameter storage |
Compared with R5F100GAGFB#X0, R5F100GGGFB#X0 adds ESD hardening without changing footprint or firmware compatibility, while R5F101GAGFB#X0 removes data flash to lower unit cost - enabling trade-offs between reliability, field-upgrade capability, and bill-of-materials expense.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GAGFB#X0?
The R5F100GAGFB#X0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. This dual-speed capability enables both high-throughput control loops and extended battery life in the same design.
Does the R5F100GAGFB#X0 support in-system programming and secure firmware updates?
Yes, the R5F100GAGFB#X0 supports full in-system programming via its on-chip debug interface and includes boot swap functionality plus a flash shield window to prevent unauthorized access to protected code regions. These features allow safe, field-upgradable firmware deployment without requiring external programmers or exposing sensitive application code during update sequences.
How many analog input channels does the R5F100GAGFB#X0 ADC support, and what reference options are available?
The R5F100GAGFB#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25). It supports external reference voltages via AVREFP/AVREFM pins and includes an internal 1.45 V reference for ratiometric measurements. The temperature sensor is also accessible through ANI25, enabling on-die thermal monitoring without external components.
What industrial temperature grade does the R5F100GAGFB#X0 meet, and how is it indicated in the part number?
The R5F100GAGFB#X0 is rated for -40°C to +105°C operation, confirmed by the "G" suffix in its part number (R5F100GAGFB#X0), which denotes the industrial temperature grade per Renesas' RL78/G13 naming convention. This qualification ensures reliable operation in demanding environments such as factory automation, motor drives, and outdoor infrastructure equipment.
Can the R5F100GAGFB#X0 execute code while rewriting data flash memory?
Yes, the R5F100GAGFB#X0 supports background operation (BGO) for data flash memory, allowing the CPU to execute instructions from program memory while simultaneously erasing or programming data flash sectors. This capability eliminates execution stalls during firmware parameter updates or data logging, ensuring deterministic real-time behavior in time-critical control applications.
