Product details
Overview
R5F100GGGFB#10 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 8 KB RAM, and industrial-grade operation up to +105°C. It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit 26-channel ADC, real-time clock with calendar, and ultra-low-power HALT/STOP/SNOOZE modes - deployed in smart metering, industrial sensor nodes, and battery-powered HMI controllers.
For engineers reviewing the R5F100GGGFB#10 datasheet, R5F100GGGFB#10 pinout, R5F100GGGFB#10 application, or R5F100GGGFB#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, G-grade temperature rating (−40°C to +105°C), integrated data flash with 1M-cycle endurance, and support for LIN-bus UART and background data flash rewriting.
Technical Context
The R5F100GGGFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 41 DMIPS at 32 MHz while maintaining 66 μA/MHz active current.

The R5F100GGGFB#10 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. Background operation (BGO) allows concurrent program execution during data flash rewriting, ensuring deterministic real-time behavior.
How does the R5F100GGGFB#10 achieve ultra-low power consumption in STOP mode?
The R5F100GGGFB#10 achieves 0.57 μA in STOP mode by powering down the CPU, flash, and most peripherals while retaining operation of the real-time clock (RTC) and low-voltage detector (LVD). This configuration enables time- or event-triggered wake-up without external components, ideal for battery-backed applications.
Is the R5F100GGGFB#10 pin-compatible with other RL78/G13 variants in the same 48-pin LFQFP package?
Yes, the R5F100GGGFB#10 shares identical pinout and electrical characteristics with other RL78/G13 devices in the 48-pin LFQFP-0.5 mm package (e.g., R5F100GGAFA#V0, R5F100GHGFB#10), enabling drop-in replacement within the same memory and temperature grade constraints - verified per Renesas pin configuration diagrams and ordering part number mapping.
