Product details
Overview
R5F100GGGNA#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 delivers 41 DMIPS at 32 MHz, consumes just 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in smart metering, industrial sensor nodes, and battery-powered HMI controllers.
For engineers reviewing the R5F100GGGNA#W0 datasheet, R5F100GGGNA#W0 pinout, R5F100GGGNA#W0 application, or R5F100GGGNA#W0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, G-grade temperature range (−40°C to +105°C), integrated data flash with 1M write cycles, low-power SNOOZE/STOP/HALT modes, and hardware multiplier/divider for deterministic control math.
Technical Context
The R5F100GGGNA#W0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with on-chip flash supporting block erase protection and self-programming with boot swap.
Peripherals include dual DMA channels (2-clock transfer latency between SFR and RAM), 8–16 channels of 16-bit timer, calendar-based RTC with alarm/correction, and 10-bit ADC with internal 1.45 V reference and temperature sensor - all operating across 1.6–5.5 V supply and −40°C to +105°C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GGAFA#V0 | LQFP-48 package (7×7 mm, 0.5 mm pitch), same memory/peripherals, but no exposed thermal pad | Better suited for reflow-sensitive assemblies or where thermal pad soldering is not feasible | Select when board assembly process cannot reliably handle HWQFN thermal pad or requires standard QFP footprint |
| R5F101GGGNA#W0 | Same package and pinout, but lacks data flash (0 KB) and has reduced RAM (8 KB) | Targeted at cost-sensitive applications where EEPROM emulation or external storage suffices | Choose when data logging or field firmware updates are unnecessary and BOM cost reduction is prioritized |
Compared with R5F100GGGNA#W0, R5F100GGAFA#V0 trades thermal performance for assembly flexibility, while R5F101GGGNA#W0 removes data flash to lower unit cost - both retain identical peripheral sets and G-grade temperature support.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GGGNA#W0?
The R5F100GGGNA#W0 operates at up to 32 MHz with a verified performance of 41 DMIPS. This metric reflects its RL78 CPU core's efficiency in executing compiled C code under typical conditions, making it suitable for real-time control tasks such as motor commutation and protocol parsing without requiring external acceleration.
Does the R5F100GGGNA#W0 include an integrated temperature sensor, and how is it accessed?
Yes, the R5F100GGGNA#W0 includes an on-chip temperature sensor accessible via ADC channel ANI25. It is calibrated at factory and usable within the −40°C to +105°C range, providing ±3°C accuracy. The sensor output is digitized by the 10-bit ADC and can be read directly through the AD conversion result register without external components.
What low-power modes does the R5F100GGGNA#W0 support, and what is the lowest achievable current draw?
The R5F100GGGNA#W0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA at 3.0 V and 25°C - confirmed in the official datasheet Rev.3.80. This enables multi-year operation on coin-cell batteries in periodic-sensing applications.
Is the R5F100GGGNA#W0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin HWQFN package (e.g., R5F100GGAFA#V0, R5F100GGGNA#W0, R5F101GGGNA#W0) share identical pinouts and electrical characteristics. This allows hardware reuse across memory/configurations - though software must account for differences in data flash presence and RAM size.
What debug interface does the R5F100GGGNA#W0 provide, and is JTAG supported?
The R5F100GGGNA#W0 uses Renesas' on-chip debug interface via the dedicated TOOLRxD/TOOLTxD pins (P11/P12), supporting full break-and-trace functionality using E2 studio and Renesas E2 emulator. JTAG is not implemented; instead, it uses single-wire SWD-like serial wire debug (SWD) over the same two-pin interface - reducing PCB routing complexity.
