Overview
R5F104GHAFB#10 from Renesas is a 48-pin LFQFP, 128 KB flash, 16 KB RAM RL78/G14 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), integrated 10-bit ADC (16 channels), RTC, and dual UART/SPI/I²C interfaces - deployed in battery-powered industrial sensor nodes and smart metering front-ends.
For engineers reviewing the R5F104GHAFB#10 datasheet, R5F104GHAFB#10 pinout, R5F104GHAFB#10 application, or R5F104GHAFB#10 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature range (G-suffix), 0.5 mm pitch LFQFP-48 package, and support for background data flash rewriting with 1M-cycle endurance.
Technical Context
The R5F104GHAFB#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (@32 MHz) to 30.5 µs (@32.768 kHz), and includes multiply/divide/accumulate instructions with 1 MB address space.
It integrates a Data Transfer Controller (DTC) with chain transfer capability, Event Link Controller (ELC) for hardware-triggered peripheral linking (19–26 event types), and on-chip power management including HALT/STOP/SNOOZE modes, POR, and 14-level LVD with interrupt/reset options.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104GHAFB#10?
The R5F104GHAFB#10 operates up to 32 MHz with a typical active current of 66 μA per MHz. At full speed, this yields ~2.1 mA total (VDD = 3.3 V, TA = 25°C). Its high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C) eliminates need for external crystal in many applications, reducing BOM count and board space.
Does the R5F104GHAFB#10 support in-system programming and secure firmware updates?
Yes, the R5F104GHAFB#10 supports full in-system programming via on-chip debug interface and includes boot swapping, flash shield window, and block erase/write prohibition features. These enable authenticated firmware updates and prevent unauthorized access to protected code sections - critical for certified industrial and metering deployments.
How many serial communication interfaces does the R5F104GHAFB#10 provide, and are they independently configurable?
The R5F104GHAFB#10 provides three UART/LIN channels, three CSI (SPI-compatible) channels, and four I²C/simplified I²C channels - all independently configurable via dedicated peripheral registers and supported by the Event Link Controller for hardware-triggered operation without CPU intervention.
What ADC capabilities does the R5F104GHAFB#10 offer for sensor interfacing?
The R5F104GHAFB#10 integrates a 10-bit successive-approximation ADC with 16 selectable analog input channels (ANI0–ANI15), internal 1.45 V reference voltage, and on-die temperature sensor. It supports scan mode, hardware trigger (e.g., from TAU), and conversion completion interrupts - ideal for multi-sensor data acquisition in compact systems.
Is the R5F104GHAFB#10 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 48-pin LFQFP-0.5 mm package - including R5F104GHAFB#10, R5F104GLAFB#10, and R5F104GHDFB#10 - share identical pinouts and electrical characteristics. This enables drop-in memory upgrades or grade substitutions without PCB redesign, provided firmware accommodates differences in flash size or temperature limits.
