Product details
Overview
R5F1018DALA#U0 from Renesas is a 25-pin WFLGA-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), optimized for ultra-low-power industrial control applications including sensor nodes and battery-powered HMI interfaces.
For engineers reviewing the R5F1018DALA#U0 datasheet, R5F1018DALA#U0 pinout, R5F1018DALA#U0 application, or R5F1018DALA#U0 equivalent, key selection criteria include its 0.57 μA STOP-mode current, integrated RTC + LVD, 10-bit 6-channel ADC, and support for UART, I²C, and CSI serial interfaces in a 3 × 3 mm WFLGA package.
Technical Context
The R5F1018DALA#U0 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 on-chip peripherals including one 12-bit interval timer, one real-time clock with calendar/alarm functions, one watchdog timer, two DMA channels, and a 16-bit × 16-bit multiplier with MAC capability - all designed for deterministic timing and low-latency interrupt response in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1008DALA#U0 | Includes 4 KB data flash memory; identical pinout, package, and peripheral set | Required where field firmware updates or parameter storage (e.g., calibration tables) must persist across power cycles | Select R5F1008DALA#U0 if non-volatile parameter retention or bootloader-safe self-programming is needed |
| R5F1017DANA#U0 | 24-pin HWQFN (4 × 4 mm); same 16 KB flash/2 KB RAM, but lacks ANI2 and one I/O pin | Suitable for space-constrained designs where 6-channel ADC or full I/O count is not required | Choose R5F1017DANA#U0 only when board area savings outweigh loss of analog channel and I/O flexibility |
Compared with R5F1018DALA#U0, R5F1008DALA#U0 adds data flash for robust parameter storage without changing footprint or power profile, while R5F1017DANA#U0 trades one analog input and I/O pin for smaller package area - both require PCB revision if substituted.

FAQ
What is the maximum operating frequency and performance of the R5F1018DALA#U0?
The R5F1018DALA#U0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline and high-accuracy on-chip oscillator (±1.0% over –20 to +85°C). The minimum instruction execution time is 0.03125 μs in high-speed mode, enabling deterministic real-time response in time-critical control loops.
Does the R5F1018DALA#U0 include data flash memory?
No, the R5F1018DALA#U0 does not include data flash memory. It contains 16 KB of code flash and 2 KB of RAM only. Data flash (4 KB) is present in the R5F1008DALA#U0 variant - the '100' prefix indicates data flash inclusion, while '101' denotes its absence. This distinction is confirmed in Renesas' part numbering scheme and memory matrix on page 2 of the datasheet.
What package type and pin count does the R5F1018DALA#U0 use?
The R5F1018DALA#U0 uses a 25-pin WFLGA (Wafer-Level Glass Array) package measuring 3 × 3 mm with 0.5 mm pitch. This is explicitly defined in Table 1-1 (page 4) of the datasheet under "25 pins / 25-pin plastic WFLGA / Not mounted / A / R5F1018AALA…R5F1018DALA…", and the RENESAS Code PWLG0025KA-A confirms the mechanical specification.
What are the low-power modes supported by the R5F1018DALA#U0?
The R5F1018DALA#U0 supports HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. STOP mode retains RTC operation and low-voltage detection while disabling the CPU and most peripherals - critical for battery-powered applications requiring periodic wake-up without external real-time clock ICs.
Which serial communication interfaces are available on the R5F1018DALA#U0?
The R5F1018DALA#U0 provides up to 3 I²C/Simplified I²C channels, 2 UART/LIN channels, and 2 CSI (SPI-compatible) channels. These are multiplexed onto P10–P17 pins per the pin configuration table (page 13), with UART supporting LIN bus physical layer compliance - enabling direct integration into automotive body electronics and industrial networks.
