Product details
Overview
R5F100GDDNA#U0 from Renesas is a 48-pin, HWQFN-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, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (26 channels), real-time clock, UART/SPI/I²C interfaces, and DMA for embedded control in battery-powered industrial sensors.
For engineers reviewing the R5F100GDDNA#U0 datasheet, R5F100GDDNA#U0 pinout, R5F100GDDNA#U0 application, or R5F100GDDNA#U0 equivalent, key selection criteria include its industrial-grade temperature rating, on-chip data flash rewrite endurance (1M cycles), hardware-accelerated multiply-accumulate unit, and support for SNOOZE mode operation with background data flash programming.
Technical Context
The R5F100GDDNA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB SRAM - enabling simultaneous program execution and nonvolatile data updates.
Peripheral integration includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 16× 16-bit timers (including calendar RTC), 3× I²C/Simplified I²C channels, 2× UART/LIN, 2× CSI (SPI-compatible), and 4-channel DMA with 2-cycle transfer between SFR and RAM - all optimized for deterministic real-time control in resource-constrained industrial nodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GFGNA#U0 | Same 48-pin HWQFN package, 128 KB flash, but 8 KB RAM (vs. 12 KB) and no data flash (0 KB vs. 8 KB). | Lacks background data flash programming; unsuitable for field-upgradable firmware requiring persistent parameter storage. | Select only when application requires minimal RAM and no nonvolatile parameter retention. |
| R5F101GDDNA#U0 | Identical pinout and peripherals, but no data flash (0 KB) and reduced RAM (8 KB vs. 12 KB); otherwise same 128 KB flash and industrial temp grade. | Cannot execute background data flash writes; eliminates capability for secure OTA updates or runtime calibration storage. | Choose only if cost sensitivity outweighs need for field-upgradeable firmware or runtime-configurable parameters. |
Compared with R5F100GDDNA#U0, R5F100GFGNA#U0 sacrifices data flash and 4 KB RAM for lower cost in static-function devices, while R5F101GDDNA#U0 retains identical flash and package but removes data flash entirely - making R5F100GDDNA#U0 the sole option among these three supporting BGO-enabled firmware updates and calibrated sensor storage.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GDDNA#U0?
The R5F100GDDNA#U0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This enables real-time execution of communication stacks (e.g., Modbus RTU), control algorithms (PID), and sensor data preprocessing without external acceleration. The minimum instruction time is 0.03125 μs under these conditions.
Does the R5F100GDDNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100GDDNA#U0 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features for secure firmware updates. Its 8 KB data flash supports background operation (BGO), allowing code execution during reprogramming - essential for robust OTA update mechanisms.
What are the key low-power modes supported by the R5F100GDDNA#U0 and their typical current draw?
The R5F100GDDNA#U0 supports HALT (1.2 μA), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, it maintains real-time clock operation and voltage monitoring while drawing less than 1 μA - enabling decade-long battery life in intermittent-sensing applications such as environmental monitors.
How many analog input channels and what ADC resolution does the R5F100GDDNA#U0 provide?
The R5F100GDDNA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and on-die temperature sensor, enabling accurate ratiometric measurements and self-calibration without external components.
Is the R5F100GDDNA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin HWQFN package (e.g., R5F100GxxNA#U0 series) share identical pinouts and electrical characteristics. This allows hardware reuse across memory/configurations - for example, upgrading from R5F100GCDNA#U0 (32 KB flash) to R5F100GDDNA#U0 (128 KB flash) requires only firmware and BOM changes.
