Product details
Overview
R5F100GEGNA#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 battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F100GEGNA#W0 datasheet, R5F100GEGNA#W0 pinout, R5F100GEGNA#W0 application, or R5F100GEGNA#W0 equivalent, key selection criteria include its G-grade temperature range (−40°C to +105°C), HWQFN-48 package with 0.5-mm pitch, integrated data flash with 1M-cycle endurance, low-power STOP/HALT/SNOOZE modes, and RL78 CPU core with 1 MB address space and CISC pipeline.
Technical Context
The R5F100GEGNA#W0 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It features dual-clock domains: a high-speed on-chip oscillator (±1.0% accuracy across 1.8–5.5 V and −20 to +85°C) and a dedicated low-speed oscillator for watchdog and RTC.
Its memory subsystem includes 128 KB code flash (1 KB block size, security-lockable), 8 KB data flash with background operation (BGO) and 1,000,000 write cycles, and 12 KB SRAM - with flash library RAM usage starting at FAF00H. Peripheral integration includes 8–16 × 16-bit timers, 1 × 12-bit interval timer, 1 × calendar RTC, 1 × watchdog, and up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GGANA#W0 | Same 48-pin HWQFN package, identical 128 KB flash / 8 KB data flash / 12 KB RAM, but A-grade (−40°C to +85°C) temperature range | Suitable for consumer or lower-ambient industrial use; lacks extended 105°C operation | Select when cost sensitivity outweighs extended temperature requirement and ambient stays ≤85°C |
| R5F101GEGNA#W0 | Same footprint and pinout, but no data flash (0 KB); retains 128 KB code flash, 12 KB RAM, and identical peripherals | Used where nonvolatile parameter storage is handled externally or not required; reduces BOM cost | Choose when application does not require embedded data logging or field-updatable calibration tables |

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GEGNA#W0?
The R5F100GEGNA#W0 operates at up to 32 MHz, achieving 41 DMIPS (Dhrystone 2.1). Its RL78 CPU core supports dynamic clock scaling from 1 MHz to 32 MHz using the high-speed on-chip oscillator, with ±1.0% accuracy across 1.8–5.5 V and −20 to +85°C. This enables deterministic real-time response in motor control and sensor fusion applications while allowing aggressive power-down during idle periods.
Does the R5F100GEGNA#W0 include integrated data flash memory, and what are its endurance specifications?
Yes, the R5F100GEGNA#W0 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for logging, calibration storage, and firmware parameter updates without system interruption.
What is the operating temperature range certified for the R5F100GEGNA#W0, and how is it indicated in the part number?
The R5F100GEGNA#W0 is qualified for industrial operation from −40°C to +105°C, denoted by the "G" suffix in the part number (R5F100GEGNA#W0). This G-grade rating ensures reliable functionality in demanding environments such as factory automation, power conversion, and medical equipment subjected to thermal cycling or sterilization.
Which package type and pin count does the R5F100GEGNA#W0 use, and what are its key mechanical attributes?
The R5F100GEGNA#W0 uses a 48-pin HWQFN package (Renesas code PWQN0048KB-A), measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. The "#W0" suffix confirms embossed tape packaging. This compact, thermally enhanced QFN enables high-density PCB layouts while supporting reflow soldering and efficient heat dissipation in fanless industrial enclosures.
How does the R5F100GEGNA#W0 support low-power system design, and what sleep modes are available?
The R5F100GEGNA#W0 provides three ultra-low-power modes: HALT (1.2 μA typical), STOP (0.57 μA with RTC + LVD active), and SNOOZE (peripheral-triggered wake-up with CPU halted). Combined with 66 μA/MHz active current and programmable voltage detector (14-level LVD), it enables energy harvesting and multi-year battery operation in edge devices - all without external supervisors or PMICs.
