Product details
Overview
R5F100EDDNA#U0 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 32 KB flash memory, 4 KB data flash, 2 KB RAM, and industrial-grade -40°C to +85°C operation. It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit 16-channel ADC, real-time clock with calendar/alarm, and ultra-low-power STOP mode (0.57 μA). It targets battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100EDDNA#U0 datasheet, R5F100EDDNA#U0 pinout, R5F100EDDNA#U0 application, or R5F100EDDNA#U0 equivalent, key selection criteria include its 40-pin HWQFN footprint, integrated data flash with background operation (BGO), 16-channel analog input capability, RTC calendar function, and support for SNOOZE mode wake-up via serial interface events.
Technical Context
The R5F100EDDNA#U0 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). It features dual-clock domains: high-speed main system clock (up to 32 MHz) and independent subsystem clock (32.768 kHz) for RTC and LVD operation during STOP mode.
Its peripheral set includes up to 16 channels of 16-bit timer, 3 UART/LIN-capable serial interfaces, 3 I²C/Simplified I²C channels, and DMA controller with 2 channels supporting 2-clock transfers between SFR and RAM. The device supports self-programming with boot swap and flash shield window functions for secure firmware updates.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100EDDFA#V0 | LQFP-44 package (10 × 10 mm, 0.8-mm pitch); same memory, peripherals, and electrical specs | Requires PCB redesign for larger footprint and different thermal pad layout; better suited for prototyping or manual assembly | Select when board space permits larger package or when hand-soldering is required |
| R5F101EDDNA#U0 | Identical package and pinout but lacks data flash memory (0 KB); retains 32 KB code flash and 2 KB RAM | Not suitable for applications requiring non-volatile parameter storage or firmware field updates without external EEPROM | Select only if data flash functionality is unnecessary and cost reduction is critical |
Compared with R5F100EDDNA#U0, R5F100EDDFA#V0 offers identical functionality in a more manufacturable LQFP package but increases board area by 55%; R5F101EDDNA#U0 removes data flash entirely, eliminating BGO and secure parameter storage - making it unsuitable for OTA-capable or calibration-critical designs.

FAQ
What is the operating temperature range for the R5F100EDDNA#U0?
The R5F100EDDNA#U0 is rated for industrial operation from –40°C to +85°C, as indicated by the 'D' suffix in its part number. This rating applies across all specified voltage ranges (1.6 V to 5.5 V) and guarantees full functionality of its RTC, ADC, and low-power modes within this ambient range.
Does the R5F100EDDNA#U0 support in-system programming via its serial interfaces?
Yes, the R5F100EDDNA#U0 supports in-system programming using the on-chip debug interface accessible through dedicated TOOLRxD/TOOLTxD pins (P11/P12). It does not support bootloader-based UART/I²C programming out-of-box - firmware updates require Renesas Flash Programmer or compatible debug probe.
How many analog input channels are available on the R5F100EDDNA#U0?
The R5F100EDDNA#U0 provides 16 analog input channels (ANI0 through ANI15), mapped to P20–P27 port pins. All channels share a single 10-bit successive-approximation ADC with selectable reference sources (VDD, AVREFP/AVREFM, or internal 1.45 V).
Can the R5F100EDDNA#U0 operate from a single 3.3 V supply?
Yes, the R5F100EDDNA#U0 operates across 1.6 V to 5.5 V, fully supporting 3.3 V nominal supply. At 3.3 V, it achieves 32 MHz maximum frequency, maintains full ADC accuracy (10-bit, ±1 LSB INL), and sustains STOP mode current at ≤0.57 μA with RTC enabled.
Is an external crystal required for real-time clock operation on the R5F100EDDNA#U0?
No - the R5F100EDDNA#U0 includes a dedicated 32.768 kHz subsystem clock that can drive the RTC independently. An external 32.768 kHz crystal connected to CLKP/CLKM improves long-term RTC accuracy to ±20 ppm, but the internal oscillator suffices for applications tolerating ±250 ppm drift.
