Renesas R5F1018EALA#U0

Overview

R5F1018EALA#U0 from Renesas is a 25-pin WFLGA-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 3 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26-channel), real-time clock, and multiple serial interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.

For engineers reviewing the R5F1018EALA#U0 datasheet, R5F1018EALA#U0 pinout, R5F1018EALA#U0 application, or R5F1018EALA#U0 equivalent, key selection criteria include its 25-pin WFLGA (3 × 3 mm, 0.5-mm pitch) footprint, absence of on-chip data flash programming capability (no data flash), -40°C to +85°C industrial temperature grade, and support for SNOOZE mode wake-up via UART/LIN or timer events.

Technical Context

The R5F1018EALA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, plus dual 16-bit timers with interval and real-time clock functions.

Its peripheral set includes up to 4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable under HALT/STOP/SNOOZE low-power states. The device lacks on-chip data flash memory (denoted by "101" in part number), distinguishing it from "100" variants that include 4–8 KB data flash.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F1018EALA#U0?

The R5F1018EALA#U0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS 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 - enabling precise trade-offs between throughput and energy consumption in the R5F1018EALA#U0 design.

Does the R5F1018EALA#U0 include on-chip data flash memory?

No, the R5F1018EALA#U0 does not include on-chip data flash memory. The "101" in its part number explicitly indicates no data flash, unlike "100" variants (e.g., R5F1008EALA#U0) which integrate 4 KB. This means non-volatile parameter storage requires external EEPROM or FRAM, and self-programming of user data is not supported in the R5F1018EALA#U0.

What package type and pin count does the R5F1018EALA#U0 use?

The R5F1018EALA#U0 uses a 25-pin WFLGA (Wafer-Level Chip-Scale Package) with 3 × 3 mm body size and 0.5-mm pitch. This land-grid array package provides superior thermal dissipation and PCB area efficiency compared to QFN or TSSOP alternatives, and is fully compatible with standard SMT reflow processes - confirmed for the R5F1018EALA#U0 in Renesas documentation.

What low-power modes are supported by the R5F1018EALA#U0, and what is the lowest achievable current draw?

The R5F1018EALA#U0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - the lowest operational current. HALT mode consumes 66 μA/MHz, and SNOOZE enables fast wake-up (<10 μs) while retaining RAM and selected peripheral context. These modes are fully implemented and characterized for the R5F1018EALA#U0 across its -40°C to +85°C operating range.

Which analog features are integrated into the R5F1018EALA#U0, and how many input channels does the ADC support?

The R5F1018EALA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), internal 1.45 V reference voltage, and an on-chip temperature sensor. These analog resources are fully functional and validated for the R5F1018EALA#U0, supporting simultaneous sampling across multiple sensors without external signal conditioning in many industrial and medical applications.
