Product details
Overview
R5F104ECANA#U0 from Renesas is a 40-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 5.5 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (44 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes, integrated RTC, 10-bit ADC (16 channels), and UART/SPI/I²C interfaces for industrial sensor control and smart metering.
For engineers reviewing the R5F104ECANA#U0 datasheet, R5F104ECANA#U0 pinout, R5F104ECANA#U0 application, or R5F104ECANA#U0 equivalent, key selection criteria include its 40-pin 6×6 mm HWQFN package, 64 KB code flash with self-programming, 10-bit 16-channel ADC, real-time clock with calendar/alarm, and support for LIN-bus-capable UART in industrial-temperature (−40°C to +85°C) operation.
Technical Context
The R5F104ECANA#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 ultra-low-speed mode), and includes multiply/divide/accumulate instructions with 1 MB address space and four banks of 8-bit general-purpose registers.
It integrates a Data Transfer Controller (DTC) with normal/repeat/block transfer modes activated by interrupts and chain transfer capability, plus an Event Link Controller (ELC) enabling hardware-triggered peripheral linking across 19–26 event signal types-reducing CPU overhead in deterministic real-time control loops.

Its ultra-low-power design achieves 66 μA/MHz in HALT mode and only 0.60 μA in STOP mode when running RTC and LVD-enabling decade-long battery life in metering and sensor applications. These values are measured at VDD = 1.8–5.5 V and TA = −40°C to +85°C per the official RL78/G14 datasheet Rev. 3.40.
Does the R5F104ECANA#U0 support in-system programming and secure firmware updates?
Yes, the R5F104ECANA#U0 supports full in-system programming via its on-chip debug interface and includes boot-swap functionality and flash shield window protection. These features allow field firmware updates without external programmers and prevent unauthorized access to protected code regions-critical for certified energy metering and industrial control deployments where firmware integrity is mandated.
How many analog input channels and what ADC resolution does the R5F104ECANA#U0 provide?
The R5F104ECANA#U0 integrates a 10-bit successive-approximation ADC with 16 configurable analog input channels (ANI0–ANI15), plus dedicated AVREFP/AVREFM pins for external reference voltage. It also includes an internal 1.45 V reference and on-die temperature sensor-enabling accurate, self-calibrating measurements across industrial temperature ranges without external components.
What serial communication interfaces are available on the R5F104ECANA#U0?
The R5F104ECANA#U0 provides three UART/LIN modules (supporting LIN 2.2 protocol), three CSI channels compatible with SPI timing, and four I²C/simplified I²C interfaces-including one with SMBus alert support. All interfaces support pin remapping via Peripheral I/O Redirection Registers (PIOR0/1), allowing flexible PCB routing and reuse of I/O resources across multiple protocols.
Is the R5F104ECANA#U0 qualified for industrial temperature operation?
Yes, the R5F104ECANA#U0 is rated for industrial ambient temperature operation from −40°C to +85°C ('D' grade). This qualification is confirmed in the RL78/G14 ordering information table, where the 'D' suffix denotes industrial-temperature capability-making it suitable for deployment in factory automation, building controls, and outdoor metering equipment without derating or additional thermal management.
