Product details
Overview
R5F100GAGNA#W0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and industrial-grade operation up to +105°C. It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit 26-channel ADC, RTC with calendar/alarm, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F100GAGNA#W0 datasheet, R5F100GAGNA#W0 pinout, R5F100GAGNA#W0 application, or R5F100GAGNA#W0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, G-grade temperature range (–40°C to +105°C), integrated data flash with 1M rewrite cycles, and support for SNOOZE mode DMA transfers during background data flash programming.
Technical Context
The R5F100GAGNA#W0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). 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 data flash rewriting.
Peripheral integration includes dual UART/LIN channels, up to 10 I²C/Simplified I²C interfaces, 8–16 × 16-bit timers, 12-bit interval timer, watchdog timer, and hardware multiplier/divider. Power management features HALT, STOP, and SNOOZE modes, with LVD interrupt/reset selectable across 14 voltage levels and POR circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GAGNA#V0 | Same die, but in 48-pin LFQFP-0.5 mm package (PLQP0048KF-A); no HWQFN thermal pad | Preferred for prototyping or boards requiring easier rework; lower thermal performance than HWQFN | Select #V0 for manual soldering or thermal budget > 1.5 W; #W0 for compact, thermally constrained designs |
| R5F101GAGNA#W0 | Omits 8 KB data flash; retains 128 KB code flash, 12 KB RAM, and identical peripherals | Suitable where firmware-only updates suffice; eliminates data logging or parameter storage requirements | Choose #W0 variant when persistent non-volatile storage beyond code flash is unnecessary |
Compared with R5F100GAGNA#W0, the #V0 alternative trades thermal efficiency for assembly flexibility, while the R5F101GAGNA#W0 reduces cost and complexity by removing data flash - making it viable only when background data rewriting is not required.

FAQ
What is the maximum operating frequency and associated DMIPS rating for the R5F100GAGNA#W0?
The R5F100GAGNA#W0 operates at up to 32 MHz using its high-accuracy on-chip oscillator and delivers 41 DMIPS. This performance level is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80) and enables real-time execution of control loops, communication stacks, and signal processing tasks without external acceleration.
Does the R5F100GAGNA#W0 support in-system programming and secure firmware updates?
Yes, the R5F100GAGNA#W0 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features. These mechanisms prevent unauthorized access during firmware updates, and the boot swap function allows atomic firmware replacement - all documented in the R5F100GAGNA#W0's self-programming section.
What are the key differences between the R5F100GAGNA#W0 and R5F101GAGNA#W0?
The R5F100GAGNA#W0 includes 8 KB of data flash memory with background operation and 1,000,000 rewrite cycles, while the R5F101GAGNA#W0 omits data flash entirely. Both share identical code flash (128 KB), RAM (12 KB), peripherals, and packaging - making the R5F101 variant suitable only when persistent non-volatile parameter storage is unnecessary.
Can the R5F100GAGNA#W0 operate reliably across the full industrial temperature range?
Yes, the R5F100GAGNA#W0 is rated for –40°C to +105°C (G-grade) operation per its ordering code suffix and datasheet specifications. This qualification covers all embedded peripherals, including the 10-bit ADC, RTC, and high-speed oscillator, ensuring consistent timing and analog performance in demanding environments like motor drives and outdoor metering.
How does the SNOOZE mode function in the R5F100GAGNA#W0, and what peripherals can trigger wake-up?
In SNOOZE mode, the R5F100GAGNA#W0 suspends CPU operation while keeping selected peripherals active - including UART, I²C, and ADC - allowing autonomous data acquisition and communication. Wake-up is triggered by configured events such as UART receive, I²C address match, or ADC conversion completion, enabling responsive low-power system behavior without continuous polling.
