Product details
Overview
R5F100GEDNA#U0 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating at 1.6–5.5 V and delivering 41 DMIPS at 32 MHz for low-power industrial control, sensor nodes, and appliance HMI applications.
For engineers reviewing the R5F100GEDNA#U0 datasheet, R5F100GEDNA#U0 pinout, R5F100GEDNA#U0 application, or R5F100GEDNA#U0 equivalent, key selection criteria include its 64 KB code flash with self-programming, ultra-low power STOP mode (0.57 μA), integrated RTC + LVD, 10-bit 26-channel ADC, and hardware UART/SPI/I²C interfaces supporting LIN-bus and background data flash rewriting.
Technical Context
The R5F100GEDNA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock), and features a unified 1 MB address space with four register banks of eight 8-bit registers each.
It integrates dual power domains: high-speed main system clock (32 MHz on-chip oscillator, ±1.0% accuracy) and independent low-speed subsystem clock for RTC/LVD operation during STOP mode, enabling calendar-based real-time functions and voltage monitoring without wake-up overhead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GEGNA#U0 | Same package and memory (64 KB flash, 4 KB data flash, 4 KB RAM), but rated for -40°C to +85°C (D-grade) instead of +105°C | Suitable for consumer or commercial equipment where ambient temperature remains below 85°C | Select when industrial-grade thermal margin is unnecessary and cost optimization is prioritized |
| R5F101GEDNA#U0 | Identical pinout and package, but lacks data flash memory (0 KB); retains same 64 KB code flash and 4 KB RAM | Applicable where firmware-only storage is sufficient and parameter retention across power cycles is not required | Choose when eliminating data flash reduces BOM cost and simplifies flash management firmware |
Compared with R5F100GEDNA#U0, the R5F100GEGNA#U0 trades extended temperature range for lower cost in milder environments, while the R5F101GEDNA#U0 removes data flash to reduce complexity and price - both retain identical peripheral sets and real-time performance for drop-in evaluation.

The R5F100GEDNA#U0 operates at up to 32 MHz using its high-speed on-chip oscillator and delivers 41 DMIPS. Its minimum instruction execution time is 0.03125 μs in HS mode, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - all verified in the R01DS0131EJ0380 datasheet.
Does the R5F100GEDNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100GEDNA#U0 supports self-programming with boot swap functionality and flash shield window protection. It allows reprogramming of code flash and data flash during runtime, with block-level erase prohibition to prevent unauthorized modification - confirmed in Section 1.1 Features of the RL78/G13 datasheet.
What analog peripherals are integrated into the R5F100GEDNA#U0?
The R5F100GEDNA#U0 integrates a 10-bit resolution ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. These are accessible via dedicated ANI pins (e.g., P20–P27) and support background operation during data flash rewriting - as specified in the "A/D converter" subsection of the datasheet.
How does the R5F100GEDNA#U0 manage power in low-energy applications?
The R5F100GEDNA#U0 offers three ultra-low-power modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC and LVD active), and SNOOZE. Its on-chip voltage detector (LVD) provides 14 selectable threshold levels for reset or interrupt, and the RTC maintains calendar time independently - all documented in the "Power management and reset function" section.
Is the R5F100GEDNA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 40-pin HWQFN package (e.g., R5F100EAANA#U0, R5F100EHANA#U0) share identical pinouts and electrical characteristics. The R5F100GEDNA#U0 is fully pin-compatible with other 40-pin G-series members, enabling scalable memory selection without PCB redesign - per Table 1-1 and Pin Configuration diagrams in R01DS0131EJ0380.
