Product details
Overview
R5F1018CALA#U0 from Renesas is a 25-pin WFLGA-packaged 16-bit RL78/G13 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), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), 10-bit ADC (6 channels), and real-time clock - deployed in battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F1018CALA#U0 datasheet, R5F1018CALA#U0 pinout, R5F1018CALA#U0 application, or R5F1018CALA#U0 equivalent, key selection criteria include its 25-pin WFLGA-0.5 mm pitch package, absence of on-chip data flash, -40°C to +85°C industrial-grade temperature range (A-grade), and integrated peripherals including UART, I²C, CSI, and 16-bit timers for compact embedded control.
Technical Context
The R5F1018CALA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock), and 1 MB address space. It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Peripherals include up to 6-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 2–4 channel DMA controller (2-cycle transfers between SFR and RAM), and serial interfaces: 2–8 CSI channels, 2–4 UART/LIN channels, and 3–10 I²C/Simplified I²C channels - all configurable without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1018DALA#U0 | Same package and core, but with 48 KB flash, 3 KB RAM, and 4 KB data flash | Supports larger firmware (e.g., OTA updates, cryptographic stacks) and nonvolatile parameter storage | Select when future firmware expansion or field calibration data persistence is required |
| R5F1008CALA#U0 | Same 25-pin WFLGA package and 16 KB flash, but includes 4 KB data flash and operates at -40°C to +105°C (G-grade) | Enables robust operation in extended-temperature environments and retains configuration across power cycles | Choose for automotive under-hood or industrial motor-drive control where data retention and thermal margin are critical |

FAQ
What is the maximum operating frequency and associated performance of the R5F1018CALA#U0?
The R5F1018CALA#U0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its high-speed on-chip oscillator achieves ±1.0% accuracy across 1.8–5.5 V and -20 to +85°C, eliminating the need for an external crystal in most applications. This frequency enables real-time processing of sensor data, motor control loops, and communication protocol stacks without external clock sources.
Does the R5F1018CALA#U0 include on-chip data flash memory?
No, the R5F1018CALA#U0 does not include on-chip data flash memory. It features 16 KB of code flash and 2 KB of RAM only. Data retention across power cycles requires external EEPROM or FRAM. For designs needing embedded nonvolatile parameter storage, consider R5F1008CALA#U0 (4 KB data flash) or R5F1018DALA#U0 (4 KB data flash) as alternatives.
What package type and pin count does the R5F1018CALA#U0 use?
The R5F1018CALA#U0 uses a 25-pin WFLGA package (3.0 × 3.0 mm, 0.5 mm pitch), designated by "LA" in the part number suffix and confirmed in Renesas documentation as PWLG0025KA-A. This ultra-compact, lead-free, RoHS-compliant package supports high-density PCB layouts and automated assembly with MSL3 handling requirements.
What is the operating temperature range specified for the R5F1018CALA#U0?
The R5F1018CALA#U0 is rated for an operating ambient temperature range of -40°C to +85°C, corresponding to the "A" grade in Renesas' classification (consumer/industrial applications). It is not qualified for extended temperature operation (e.g., -40°C to +105°C), which is supported by G-grade variants like R5F1008CALA#U0.
Which serial communication interfaces are integrated into the R5F1018CALA#U0?
The R5F1018CALA#U0 integrates multiple serial interfaces: up to 4 UART/LIN channels (supporting LIN 2.2), up to 8 CSI channels (SPI-compatible), and up to 10 I²C/Simplified I²C channels. These can be flexibly assigned to different pins via register configuration, enabling concurrent communication with sensors, displays, and transceivers without external bus expanders.
