Product details
Overview
R5F100GADNA#W0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for industrial control and sensor interface applications.
For engineers reviewing the R5F100GADNA#W0 datasheet, R5F100GADNA#W0 pinout, R5F100GADNA#W0 application, or R5F100GADNA#W0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G-suffix), embossed tape packaging (#W0), integrated 10-bit ADC (26 channels), real-time clock with calendar, and hardware DMA support for deterministic peripheral handling.
Technical Context
The R5F100GADNA#W0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution time from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual serial interfaces - up to 4 UART/LIN channels and up to 10 I²C/Simplified I²C channels - with independent clock domains for mixed-protocol communication.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and a high-accuracy ±1.0% on-chip oscillator (1–32 MHz). 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 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GAGNA#W0 | Same package and memory (128 KB flash, 8 KB data flash, 12 KB RAM), but rated for -40°C to +85°C (D-grade) instead of +105°C (G-grade) | Suitable for consumer or lower-ambient industrial environments where extended temperature range is not required | Select when cost optimization is prioritized and ambient operating temperature remains ≤ +85°C |
| R5F101GADNA#W0 | Identical pinout and package, but lacks data flash memory (0 KB); retains same 128 KB code flash and 12 KB RAM | Applicable where firmware-only storage suffices and EEPROM-like nonvolatile parameter storage is handled externally | Choose when data logging or field-updatable configuration parameters are not needed, reducing BOM complexity |
Compared with R5F100GADNA#W0, R5F100GAGNA#W0 trades extended temperature capability for lower unit cost, while R5F101GADNA#W0 removes data flash to simplify qualification and reduce test overhead - both retain identical real-time performance, peripheral count, and low-power behavior.
