Product details
Overview
R5F100GFGFB#10 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for industrial control, sensor nodes, and low-power HMI in -40°C to +105°C environments.
For engineers reviewing the R5F100GFGFB#10 datasheet, R5F100GFGFB#10 pinout, R5F100GFGFB#10 application, or R5F100GFGFB#10 equivalent, key selection criteria include its industrial-grade temperature rating (G suffix), integrated RTC with calendar/alarm, background data flash rewrite capability, and ultra-low power consumption (0.57 μA in STOP mode with RTC+LVD active).
Technical Context
The R5F100GFGFB#10 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 dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog/RTC.
Its peripheral set includes up to 16× 16-bit timers, 3–10× I²C/Simplified I²C channels, 2–4× UART/LIN interfaces, 2–8× CSI (SPI-compatible) channels, and DMA controller with 4 channels - all operating under single 1.6–5.5 V supply with on-chip POR and 14-level LVD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and code density advantage over ARM Cortex-M0+ in cost-sensitive embedded control. |
| Flash / Data Flash / RAM | 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), 12 KB SRAM - supports firmware updates without halting application execution. |
| Power Consumption | 66 μA/MHz active; 0.57 μA in STOP mode with RTC + LVD enabled - enables battery-powered operation for >10 years in sensor wake-on-event designs. |
| ADC Resolution & Channels | 10-bit SAR ADC with 26 analog inputs and internal 1.45 V reference - sufficient for precision temperature, pressure, and current sensing without external references. |
| Operating Temperature | -40°C to +105°C (G-grade industrial qualification) - validated for motor drives, industrial PLC I/O modules, and automotive cabin electronics. |
| Clock Sources | High-accuracy on-chip oscillator (±1.0% from 1.8–5.5 V, -20–+85°C); dedicated low-speed oscillator for RTC/WDT - eliminates need for external crystals in many applications. |
| Real-Time Clock | Calendar-mode RTC with alarm, clock correction, and 99-year date range - provides timestamping and scheduled wake-up without host MCU intervention. |
Pinout & Package
Package: 48-pin LFQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3. Pin count and footprint align with standard PCB assembly processes and thermal management requirements for industrial ambient conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10/SCK00/SCL00 | Primary SPI clock / I²C clock | Shared function pin enabling flexible interface selection; supports master/slave SPI and standard-mode I²C (100 kHz) without external logic. |
| P11/SI00/RxD0/TOOLRxD/SDA00 | SPI input / UART receive / debug RX / I²C data | Multi-function I/O critical for programming (TOOLRxD), serial comms (RxD0), and sensor bus (SDA00); requires careful signal routing to avoid conflict during boot. |
| P20/ANI0/AVREFP | Analog input 0 / ADC reference positive | Enables external voltage reference or direct sensor connection; AVREFP use improves ADC accuracy when external reference is applied. |
| P21/ANI1/AVREFM | Analog input 1 / ADC reference negative | Paired with P20 to define differential ADC reference window; supports ratiometric sensor measurements and noise rejection. |
| P40/INTP0/TOOLnTRST | External interrupt 0 / JTAG reset | Dual-role pin used for both application-level event detection (e.g., button press) and debug interface reset - must be pulled appropriately for reliable JTAG access. |
| P50/CLKP/CLKOUT | System clock output | Drives external logic or timing circuits at system clock frequency; configurable as divided clock for synchronization of companion ICs. |
Key Features
| Feature | Design Value |
|---|---|
| Self-programming with boot swap | Enables field firmware updates with zero downtime via dual-bank flash layout - critical for remote industrial equipment maintenance. |
| Background data flash rewrite (BGO) | Allows concurrent program execution and non-volatile parameter storage (e.g., calibration data, usage logs) without interrupt latency spikes. |
| SNOOZE mode with peripheral wakeup | Permits selective peripheral operation (e.g., ADC scan, UART receive) while CPU sleeps - reduces average power by >90% vs full active mode. |
| On-chip temperature sensor | Provides system thermal monitoring without external components; calibrated for ±3°C accuracy across -40°C to +105°C range. |
| Hardware multiplier/divider/MAC | Accelerates PID control, filtering, and sensor linearization in real time - eliminates need for software-based math libraries and associated code size overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GGGFB#10 | Same package and memory (128 KB flash, 8 KB data flash, 12 KB RAM), but G-grade (−40°C to +105°C) with identical pinout and peripherals. | No functional difference; intended for same industrial applications requiring extended temperature range. | Select R5F100GGGFB#10 only if documentation explicitly requires G-grade marking - otherwise R5F100GFGFB#10 is functionally identical and qualified for −40°C to +105°C. |
| R5F101GFGFB#10 | Same footprint and pinout, but lacks data flash memory (0 KB); retains 128 KB code flash, 12 KB RAM, and identical peripherals except data flash-related functions. | Suitable where field firmware updates or non-volatile parameter storage are not required - reduces BOM cost and simplifies flash management. | Choose R5F101GFGFB#10 when data flash is unused; verify that bootloader, calibration storage, and logging features can be implemented in code flash or external EEPROM. |
Compared with R5F100GGGFB#10, R5F100GFGFB#10 offers identical industrial temperature performance and functionality; compared with R5F101GFGFB#10, it adds 8 KB background-operable data flash essential for robust field-upgrade and parameter retention architectures.
