Product details
Overview
R5F100EAANA#W0 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), and real-time clock with calendar function - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100EAANA#W0 datasheet, R5F100EAANA#W0 pinout, R5F100EAANA#W0 application, or R5F100EAANA#W0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, 64 KB code flash with self-programming and boot swap, 10-bit ADC accuracy over full VDD range (1.6–5.5 V), and support for SNOOZE mode wake-up via serial interface or timer events.
Technical Context
The R5F100EAANA#W0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: main system clock (up to 32 MHz) and independent low-speed on-chip oscillator for watchdog and RTC operation.
Its peripheral set includes 2–4 channel DMA, 8–16-channel 16-bit timers, 2–4 UART/LIN interfaces, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) interfaces - all configurable under HALT, STOP, and SNOOZE low-power states without sacrificing interrupt latency or peripheral responsiveness.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FAAFP | 44-pin LQFP, 96 KB flash, 8 KB RAM, same 4 KB data flash; adds 2 extra UART and 2 extra I²C channels. | Better suited for designs requiring more serial interfaces and larger code footprint, e.g., gateway controllers. | Select when board layout allows larger package and additional peripherals justify higher cost and memory overhead. |
| R5F101EAANA#W0 | Same 40-pin HWQFN package and 64 KB flash, but no data flash memory; otherwise identical peripheral set and power specs. | Appropriate for cost-sensitive applications where EEPROM or external flash replaces data retention needs. | Choose when firmware does not require in-field parameter storage or calibration data persistence. |
Compared with R5F100FAAFP, the R5F100EAANA#W0 offers smaller footprint and lower system BOM cost at the expense of serial interface count; compared with R5F101EAANA#W0, it provides guaranteed 4 KB data flash endurance (1M cycles) essential for secure firmware update logging and sensor calibration history.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100EAANA#W0?
The R5F100EAANA#W0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This benchmark reflects its RL78 CPU core efficiency with 3-stage pipeline execution, validated per EEMBC CoreMark methodology. The R5F100EAANA#W0 maintains this performance across its full 1.6–5.5 V supply range and -40°C to +85°C ambient temperature.
Does the R5F100EAANA#W0 support in-system programming and secure firmware updates?
Yes, the R5F100EAANA#W0 supports full in-system programming via its on-chip debug interface and self-programming flash controller. It implements boot swap functionality and flash shield window protection to prevent unauthorized access during firmware updates. These features enable secure over-the-air (OTA) updates and field reprogramming without external hardware tools - critical for deployed R5F100EAANA#W0-based metering and sensor systems.
How many analog input channels does the R5F100EAANA#W0 ADC support, and what reference options are available?
The R5F100EAANA#W0 integrates a 10-bit successive approximation register (SAR) ADC with up to 26 analog input channels (ANI0–ANI25). It supports two reference voltage sources: externally supplied VDD or an internal 1.45 V bandgap reference. The internal reference enables stable, supply-independent measurements - especially valuable in battery-operated R5F100EAANA#W0 applications where VDD may vary significantly during discharge.
What low-power modes are available on the R5F100EAANA#W0, and what is the lowest achievable current consumption?
The R5F100EAANA#W0 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at 25°C. This ultra-low quiescent current enables decade-long battery life in applications like utility meters and environmental sensors - a key differentiator of the R5F100EAANA#W0 within the RL78/G13 family.
Is the R5F100EAANA#W0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 40-pin HWQFN package (e.g., R5F100FAANA, R5F100GAANA) share identical pinouts and electrical characteristics. This allows direct substitution between variants - such as upgrading from R5F100EAANA#W0 (64 KB flash) to R5F100FAANA#W0 (96 KB flash) - without PCB redesign. The R5F100EAANA#W0's pin mapping is fully documented in Renesas' R01DS0131EJ0380 datasheet Section 1.3.4.
