Product details
Overview
R5F100GDGFB#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 modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and integrated real-time clock - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GDGFB#X0 datasheet, R5F100GDGFB#X0 pinout, R5F100GDGFB#X0 application, or R5F100GDGFB#X0 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), on-chip debug support, self-programmable data flash with background operation, and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F100GDGFB#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz) and 1 MB address space. It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog/RTC.
Peripherals include 8-channel 16-bit timers, 12-bit interval timer, calendar-based RTC with alarm/correction, 2–4 channel DMA, UART/LIN, I²C, CSI, 16×16-bit MAC, and hardware BCD correction - all designed for deterministic real-time control in resource-constrained embedded systems without external timing or memory support.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GDGFB#X0 | No data flash (0 KB); identical core, peripherals, and package | Suitable where firmware updates or parameter logging are handled externally | Select when eliminating data flash reduces cost and security requirements are minimal |
| R5F100GAGFB#X0 | Same package and temp grade, but 96 KB flash / 8 KB data flash / 8 KB RAM | Lower memory configuration for cost-sensitive designs with reduced feature set | Choose when application firmware fits within 96 KB and 8 KB RAM suffices for stack/heap |
Compared with R5F100GDGFB#X0, R5F101GDGFB#X0 removes data flash to lower unit cost and simplify programming flow, while R5F100GAGFB#X0 trades 32 KB flash and 4 KB RAM for lower bill-of-materials - both retain identical pinout, timing, and peripheral compatibility for drop-in layout reuse.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GDGFB#X0?
The R5F100GDGFB#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. All timing specifications are validated across the full −40°C to +105°C industrial temperature range.
Does the R5F100GDGFB#X0 support in-system programming and secure firmware updates?
Yes, the R5F100GDGFB#X0 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features for firmware security. Self-programming is enabled with boot swap functionality, allowing safe dual-bank firmware updates without external programmers - verified in Renesas Flash Self-Programming Library R20UT2944.
What are the key low-power modes supported by the R5F100GDGFB#X0, and what is the typical current draw in each?
The R5F100GDGFB#X0 supports HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, only RTC and LVD remain powered, enabling decade-scale battery operation in sensor nodes. HALT retains full RAM and register state while stopping the CPU clock, and SNOOZE allows selected peripherals like UART to remain active for event-driven wake-up.
Can the R5F100GDGFB#X0 interface directly with 1.8 V or 2.5 V logic devices?
Yes, the R5F100GDGFB#X0 I/O ports support different-potential interfacing: pins designated for EVDD withstand voltage (64–128 pin variants) or VDD withstand voltage (20–52 pin variants) accept 1.8 V, 2.5 V, or 3.0 V inputs without level shifters. The R5F100GDGFB#X0 is a 48-pin variant with VDD-tolerant I/O, enabling direct connection to 1.8 V/2.5 V peripherals when VDD ≥ 1.8 V.
Is an external crystal required for real-time clock operation in the R5F100GDGFB#X0?
No, the R5F100GDGFB#X0 includes a dedicated low-power oscillator for RTC operation and does not require an external crystal. However, CLKP/CLKM pins support optional 32.768 kHz crystal connection to improve RTC accuracy beyond the internal oscillator's ±30 ppm specification - useful in time-critical applications like energy metering calibration.
