Product details
Overview
R5F100ECDNA#U0 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 2 KB RAM, operating at 1.6–5.5 V and delivering 41 DMIPS at 32 MHz. It integrates an ultra-low-power CPU core (66 μA/MHz active, 0.57 μA RTC+LVD), 10-bit ADC (26 channels), real-time clock, UART/SPI/I²C interfaces, and DMA for embedded control in battery-powered industrial sensors and smart actuators.
For engineers reviewing the R5F100ECDNA#U0 datasheet, R5F100ECDNA#U0 pinout, R5F100ECDNA#U0 application, or R5F100ECDNA#U0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, 64 KB code flash with self-programming and flash shield window, 10-bit ADC with internal reference and temperature sensor, and support for HALT/STOP/SNOOZE low-power modes across –40°C to +85°C industrial operation.
Technical Context
The R5F100ECDNA#U0 implements the RL78 CISC CPU core with 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). It features on-chip debug, background operation during data flash rewriting, and a dedicated low-speed on-chip oscillator for watchdog timer independence.
Its peripheral set includes up to 26-channel 10-bit ADC with selectable internal 1.45 V reference and integrated temperature sensor, eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock with alarm and correction, and three serial interface types (CSI, UART/LIN, I²C) configurable across 2–10 channels depending on variant.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100EDDNA#U0 | Same 40-pin HWQFN package, identical 64 KB flash/4 KB data flash/2 KB RAM, but rated for A-grade (–40°C to +85°C consumer) instead of D-grade industrial | Lacks industrial qualification - not suitable for environments with extended temperature cycling or long-term reliability requirements | Select only for cost-sensitive consumer products where full industrial qualification is unnecessary |
| R5F101ECDNA#U0 | Same footprint and pinout, but omits data flash memory (0 KB) and reduces RAM to 2 KB; otherwise identical core/peripherals | No background data logging capability - unsuitable for applications requiring nonvolatile parameter storage or firmware update staging | Choose when data flash functionality is unused and BOM cost reduction is prioritized over field upgrade flexibility |
Compared with R5F100ECDNA#U0, R5F100EDDNA#U0 trades industrial temperature certification for lower unit cost, while R5F101ECDNA#U0 removes data flash to reduce silicon area - both retain identical performance, peripherals, and package compatibility but constrain specific design capabilities.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100ECDNA#U0?
The R5F100ECDNA#U0 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS (Dhrystone MIPS) performance. Its minimum instruction execution time is 0.03125 μs at this speed, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time.
Does the R5F100ECDNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100ECDNA#U0 supports full in-system programming via its on-chip debug interface and includes flash shield window functionality to protect designated code regions from unauthorized read/write access. It also implements boot swap capability for safe dual-bank firmware updates without runtime interruption.
How many analog input channels does the R5F100ECDNA#U0 ADC support, and what reference options are available?
The R5F100ECDNA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference voltages or the internal 1.45 V reference (VREF) for consistent measurement accuracy across supply variations - the latter is selectable only in HS (high-speed main) mode per datasheet note.
What low-power modes are implemented in the R5F100ECDNA#U0, and what is the lowest achievable current draw?
The R5F100ECDNA#U0 implements HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA typical at 25°C - enabling multi-year operation on primary lithium batteries in remote sensing applications.
Is the R5F100ECDNA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 40-pin HWQFN package (e.g., R5F100ECxxx#U0, R5F100EDxxx#U0, R5F101ECxxx#U0) share identical pinouts and mechanical footprint. This allows hardware reuse across memory/configurations - though functional differences (e.g., data flash presence, temperature grade) must be verified in software and qualification testing.
