Product details
Overview
R5F100GCGFB#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 across –40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates RTC, 10-bit ADC (24 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F100GCGFB#X0 datasheet, R5F100GCGFB#X0 pinout, R5F100GCGFB#X0 application, or R5F100GCGFB#X0 equivalent, key selection criteria include its industrial-grade temperature rating (–40°C to +105°C), on-chip data flash rewrite endurance (1,000,000 cycles), real-time clock calendar function, and support for background data flash programming during code execution.
Technical Context
The R5F100GCGFB#X0 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 low-speed mode). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB SRAM - all accessible within a 1 MB address space.
Peripherals are tightly integrated: dual DMA controller (4 channels), 16-bit timer array (12 channels), 12-bit interval timer, watchdog timer, and serial interfaces including up to 10 I²C/Simplified I²C channels, 4 UART/LIN channels, and 8 CSI (SPI-compatible) channels - all configurable via dedicated SFRs and interrupt vectors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GAGFB#X0 | Same package and pinout; reduced memory (64 KB flash, 4 KB data flash, 4 KB RAM) and no RTC calendar function. | Suitable for cost-sensitive, non-time-stamped control tasks (e.g., basic LED drivers or fan controllers). | Select when RTC calendar, extended data logging, or >64 KB firmware footprint are unnecessary. |
| R5F101GCGFB#X0 | Identical package and peripherals but lacks data flash memory; retains 128 KB code flash and 12 KB RAM. | Applicable where firmware updates occur only via external host, eliminating need for field-upgradable parameter storage. | Choose when configuration persistence is handled externally (e.g., EEPROM or cloud sync), reducing BOM count and security attack surface. |
Compared with R5F100GCGFB#X0, R5F100GAGFB#X0 trades data flash capacity and RTC calendar for lower unit cost, while R5F101GCGFB#X0 removes data flash entirely to simplify firmware update architecture - both retain identical industrial temperature rating and ultra-low-power STOP mode performance.
