Product details
Overview
R5F1017DDNA#U0 from Renesas is a 24-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 48 KB flash, 4 KB data flash, and 3 KB RAM, operating at 1.6–5.5 V and supporting ultra-low-power modes (0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock for industrial sensor control and battery-powered HMI applications.
For engineers reviewing the R5F1017DDNA#U0 datasheet, R5F1017DDNA#U0 pinout, R5F1017DDNA#U0 application, or R5F1017DDNA#U0 equivalent, key selection criteria include its 24-pin HWQFN-0.5mm pitch package, absence of on-chip data flash (per part number coding), -40°C to +85°C industrial temperature grade, and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F1017DDNA#U0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz). It features dual-clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, calendar-based RTC with alarm and correction, and background operation (BGO) capable data flash programming-though this specific variant omits data flash per "101" family coding, relying solely on code flash for nonvolatile storage.

Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1017DANA#U0 | Same package and memory (48 KB flash, 3 KB RAM), but "A" grade (-40°C to +85°C consumer) instead of "D" industrial grade | Suitable for non-critical commercial equipment where extended temperature validation is not required | Select when BOM cost reduction is prioritized and ambient operating conditions remain within consumer spec |
| R5F1007DDNA#U0 | Identical pinout and package, but includes 4 KB data flash (vs. none in R5F1017DDNA#U0) and 4 KB RAM (vs. 3 KB) | Better suited for firmware-over-the-air (FOTA) updates and parameter logging requiring persistent nonvolatile storage | Choose when field-upgradable firmware or runtime configuration storage is mandatory |
Compared with R5F1017DDNA#U0, R5F1017DANA#U0 trades industrial temperature qualification for lower cost, while R5F1007DDNA#U0 adds data flash and RAM at the expense of higher unit price and slightly increased power in active mode.

FAQ
What is the flash memory configuration of the R5F1017DDNA#U0?
The R5F1017DDNA#U0 contains 48 KB of code flash memory and no on-chip data flash. This is confirmed by the "101" in the part number, which denotes absence of data flash per Renesas RL78/G13 family coding rules. Code flash supports self-programming with boot swap and flash shield window functions, enabling secure firmware updates in the R5F1017DDNA#U0.
Does the R5F1017DDNA#U0 support hardware debugging?
Yes, the R5F1017DDNA#U0 includes an on-chip debug function compatible with Renesas E2 emulator and E2 studio IDE. It supports breakpoints, watchpoints, and real-time variable monitoring via the single-wire debug (SWD) interface using the dedicated DEBUG pin, enabling full firmware development and validation without external JTAG adapters.
What is the maximum ADC sampling rate achievable on the R5F1017DDNA#U0?
The R5F1017DDNA#U0 ADC achieves up to 300 kSPS at 10-bit resolution when using the internal high-speed oscillator at 32 MHz. Conversion time is 1.5 μs per sample, and the 26-channel input multiplexer allows rapid scanning across multiple sensors without CPU intervention, making it suitable for real-time environmental monitoring in the R5F1017DDNA#U0.
Can the R5F1017DDNA#U0 operate from a single 1.8 V supply?
Yes, the R5F1017DDNA#U0 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supply. At 1.8 V, it delivers full functionality including 10-bit ADC, UART, and RTC, though maximum CPU frequency is reduced to 16 MHz. This enables direct integration with 1.8 V logic families and low-voltage battery systems in the R5F1017DDNA#U0 design.
