Product details
Overview
R5F104GAANA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and industrial-grade operation up to +105°C. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), integrated 10-bit ADC (20 channels), dual UART/LIN, and hardware DTC/ELC for deterministic real-time control in battery-powered industrial sensors.
For engineers reviewing the R5F104GAANA#U0 datasheet, R5F104GAANA#U0 pinout, R5F104GAANA#U0 application, or R5F104GAANA#U0 equivalent, key selection criteria include its 48-pin HWQFN (7×7 mm, 0.5 mm pitch) footprint, G-grade temperature rating (−40 to +105°C), on-chip 12-bit RTC with calendar/alarm, and support for background data flash rewriting (1M cycles) at 1.8–5.5 V.
Technical Context
The R5F104GAANA#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). Its power management includes dedicated low-speed oscillator for watchdog timer and LVD with 14 selectable voltage thresholds.
Peripheral integration includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, real-time clock with calendar function, and Event Link Controller (ELC) enabling direct peripheral-to-peripheral signal routing without CPU intervention-reducing latency and interrupt overhead in time-critical applications.

What are the power supply requirements and low-power capabilities of the R5F104GAANA#U0?
The R5F104GAANA#U0 operates from a single 1.6–5.5 V supply and features three ultra-low-power modes: HALT (66 μA/MHz), STOP (0.60 μA with RTC + LVD active), and SNOOZE (selective peripheral wake-up). It includes an on-chip voltage regulator requiring a 0.47–1 μF REGC capacitor, and a 14-level LVD for precise brown-out detection. These features make the R5F104GAANA#U0 ideal for energy harvesting and coin-cell-powered applications where runtime and reliability are critical.
How many analog input channels and what ADC resolution does the R5F104GAANA#U0 provide?
The R5F104GAANA#U0 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), including dedicated AVREFP/AVREFM pins for ratiometric measurement. It supports internal 1.45 V reference voltage and on-chip temperature sensing-enabling accurate environmental monitoring without external references. The ADC operates across the full 1.6–5.5 V supply range, ensuring consistent performance in varying battery conditions.
Is the R5F104GAANA#U0 pin-compatible with other RL78/G14 variants in the same package?
Yes, the R5F104GAANA#U0 is pin-compatible with all 48-pin HWQFN RL78/G14 variants-including R5F104GGANA#U0 (128 KB flash) and R5F104GHANA#U0 (192 KB flash)-as they share identical pin configuration, electrical characteristics, and peripheral mapping.
