Product details
Overview
R5F104BCANA#U0 from Renesas is a 32-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 16 KB flash, 2.5 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V at -40 to +85°C (A-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), and integrates UART, I²C, SPI, 10-bit ADC (16 channels), RTC, and on-chip oscillators up to 32 MHz - used in battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F104BCANA#U0 datasheet, R5F104BCANA#U0 pinout, R5F104BCANA#U0 application, or R5F104BCANA#U0 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm, 0.5 mm pitch) footprint, A-grade temperature rating, 16 KB flash capacity, integrated data flash for parameter storage, and support for SNOOZE mode for low-power wake-up event handling.
Technical Context
The R5F104BCANA#U0 implements the RL78 CPU core with a 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). It includes multiply/divide/accumulate instructions and a 1 MB address space.
It integrates a Data Transfer Controller (DTC) with normal, repeat, and block transfer modes activated by interrupts, plus an Event Link Controller (ELC) enabling 19–26 peripheral event signals to trigger functions without CPU intervention - critical for deterministic real-time response in motor control and metering applications.

Does the R5F104BCANA#U0 support in-system programming and secure flash protection?
Yes, the R5F104BCANA#U0 supports full in-system programming via on-chip debug interface and includes flash security features such as block erase prohibition and flash shield window function. These mechanisms prevent unauthorized readout or modification of code flash contents, meeting basic firmware IP protection requirements for commercial deployments.
How many analog input channels does the R5F104BCANA#U0 provide, and what is the ADC resolution?
The R5F104BCANA#U0 integrates a 10-bit successive approximation register (SAR) ADC with up to 16 analog input channels (ANI0–ANI15), plus dedicated AVREFP/AVREFM pins for precise reference voltage control. It also includes an internal 1.45 V reference and on-die temperature sensor, enabling calibrated measurements without external components.
What low-power modes are available on the R5F104BCANA#U0, and what is the lowest achievable current draw?
The R5F104BCANA#U0 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.60 μA typical at 25°C - verified per Renesas datasheet R01DS0053EJ0340. This enables decade-long operation on primary lithium cells in maintenance-free remote sensors.
Is the R5F104BCANA#U0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 32-pin HWQFN package (e.g., R5F104BAANA#U0, R5F104BEANA#U0) share identical pinouts and electrical characteristics.
