Product details
Overview
R5F100GCGNA#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 32 MHz (41 DMIPS), supporting ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and multiple serial interfaces (UART, I²C, CSI) for industrial control and sensor node applications.
For engineers reviewing the R5F100GCGNA#W0 datasheet, R5F100GCGNA#W0 pinout, R5F100GCGNA#W0 application, or R5F100GCGNA#W0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), embossed tape packaging (#W0), integrated real-time clock with calendar/alarm, and hardware multiplier/divider for deterministic math in motor control and metering firmware.
Technical Context
The R5F100GCGNA#W0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock), and features an address space of 1 MB with four register banks of eight 8-bit registers each.
It integrates a 12-bit interval timer, one real-time clock with calendar support up to 99 years, one watchdog timer with dedicated low-speed oscillator, and DMA controller with 4 channels enabling 2-clock transfers between SFR and internal RAM - critical for deterministic peripheral handling in time-sensitive embedded systems.

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 pinout; reduced memory (64 KB flash, 4 KB data flash, 4 KB RAM) | Suitable for simpler firmware with no data logging or complex UI; lower cost where feature set permits | Select when application requires <64 KB code, <4 KB persistent storage, and operates within -40°C to +105°C |
| R5F101GCGNA#W0 | Same footprint but no data flash; identical core, peripherals, and power specs | Requires external EEPROM or FRAM for nonvolatile parameter storage; eliminates flash wear management overhead | Choose when design uses external nonvolatile memory or relies solely on code flash for configuration storage |
Compared with R5F100GCGNA#W0, R5F100GAGNA#W0 trades memory capacity for cost reduction in resource-constrained designs, while R5F101GCGNA#W0 removes data flash to simplify firmware architecture at the expense of integrated parameter retention - both retain identical industrial temperature rating and ultra-low-power operation.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100GCGNA#W0?
The R5F100GCGNA#W0 operates at a maximum frequency of 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) performance. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V and -40°C to +105°C. The R5F100GCGNA#W0 sustains this performance while consuming only 66 μA per MHz in active mode.
Does the R5F100GCGNA#W0 include integrated data flash memory, and what is its endurance specification?
Yes, the R5F100GCGNA#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 during data flash rewriting - essential for robust firmware updates and parameter logging in the R5F100GCGNA#W0.
What package type and pin count does the R5F100GCGNA#W0 use, and what does the "#W0" suffix indicate?
The R5F100GCGNA#W0 uses a 48-pin HWQFN package (7 × 7 mm, 0.5-mm pitch) with an exposed thermal pad. The "#W0" suffix denotes embossed tape packaging - standard for automated SMT assembly - and confirms compliance with Renesas' moisture sensitivity level (MSL) 3 handling requirements for the R5F100GCGNA#W0.
How does the R5F100GCGNA#W0 support ultra-low-power operation in battery-powered applications?
The R5F100GCGNA#W0 achieves ultra-low-power operation through three dedicated modes: HALT (core stopped, peripherals running), STOP (all clocks halted except RTC and LVD), and SNOOZE (peripheral-triggered wake-up without CPU restart). In STOP mode with RTC + LVD active, it draws just 0.57 μA - enabling multi-year battery life in sensor nodes using the R5F100GCGNA#W0.
What serial communication interfaces are available on the R5F100GCGNA#W0, and how many channels does each support?
The R5F100GCGNA#W0 integrates UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible, up to 8 channels). All interfaces are multiplexed across GPIO pins and support independent clock sources, enabling concurrent communication with displays, sensors, gateways, and legacy industrial buses in designs based on the R5F100GCGNA#W0.
