Product details
Overview
R5F104GEAFB#10 from Renesas is a 48-pin LFQFP, 48 KB flash, 5.5 KB RAM RL78/G14 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), 32 MHz max CPU speed, and integrated 10-bit ADC (16 channels), UART (3 ch), I²C (4 ch), and RTC. It targets battery-powered industrial sensor nodes and low-cost motor control.
For engineers reviewing the R5F104GEAFB#10 datasheet, R5F104GEAFB#10 pinout, R5F104GEAFB#10 application, or R5F104GEAFB#10 equivalent, key selection criteria include its 48-pin 0.5 mm pitch LFQFP package, -40°C to +85°C industrial temperature grade (D), 48 KB code flash with data flash, and support for SNOOZE mode for event-driven wake-up.
Technical Context
The R5F104GEAFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a Data Transfer Controller (DTC) for autonomous memory transfers triggered by peripherals and an Event Link Controller (ELC) that routes 19–26 event signals directly to peripheral functions without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE modes, with real-time clock operation at 0.60 μA and on-chip voltage detector (LVD) offering 14 selectable reset/interrupt thresholds. The high-accuracy ±1.0% on-chip oscillator supports frequencies from 1 to 64 MHz across 1.8–5.5 V supply range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104GEAFP#V0 | Same core, flash, RAM, and peripherals; differs only in 48-pin LQFP (0.8 mm pitch) package | Requires PCB redesign due to larger pad pitch and footprint; suited for prototyping or legacy LQFP layouts | Select when existing board uses 0.8 mm pitch LQFP or when thermal dissipation margin is critical (larger body) |
| R5F104BEAFB#10 | Identical 48-pin LFQFP package but with 32 KB flash and 4 KB RAM; otherwise identical peripheral set and power specs | Targeted at cost-sensitive applications with smaller firmware footprints and reduced data logging needs | Choose for simplified BOM where 32 KB flash suffices and $0.15–$0.20 unit cost reduction is prioritized |
Compared with R5F104GEAFB#10, R5F104GEAFP#V0 offers identical functionality in a less space-constrained LQFP package, while R5F104BEAFB#10 reduces memory capacity to lower cost-both retain the same ultra-low-power architecture and industrial temperature rating.
