Product details
Overview
R5F100GADNA#U0 from Renesas is a 48-pin RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at 1.6–5.5 V with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F100GADNA#U0 datasheet, R5F100GADNA#U0 pinout, R5F100GADNA#U0 application, or R5F100GADNA#U0 equivalent, key selection criteria include its HWQFN-48 package, -40°C to +105°C industrial temperature grade (G suffix), integrated RTC with calendar/alarm, 10-bit 26-channel ADC, and hardware UART/SPI/I²C interfaces for embedded telemetry and motor control.
Technical Context
The R5F100GADNA#U0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and features a 1 MB address space with four 8-bit register banks. It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC operation.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and LVD (14-level selectable), and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM. The device supports background data flash rewriting (BGO) with 1M write cycles and self-programming with boot swap and flash shield window functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GAGNA#U0 | Same 48-pin HWQFN package, identical 128 KB flash/8 KB data flash/12 KB RAM, but rated for -40°C to +85°C (D-grade) | Suitable for consumer or lower-temperature industrial use; lacks extended thermal margin for high-ambient enclosures | Select when cost-sensitive designs operate within 85°C ambient and do not require full industrial temperature qualification |
| R5F101GADNA#U0 | Pin-compatible 48-pin HWQFN variant with no data flash (0 KB), same 128 KB code flash and 12 KB RAM | Applicable where firmware updates occur only via external host or where EEPROM emulation is handled externally | Choose when data retention requirements are met by external memory or when flash wear-out concerns preclude internal data flash usage |
Compared with R5F100GADNA#U0, R5F100GAGNA#U0 trades extended temperature capability for lower cost in milder environments, while R5F101GADNA#U0 removes data flash to simplify firmware architecture and eliminate BGO complexity-both retain identical peripheral sets and real-time performance.
