Product details
Overview
R5F104GFAFB#10 from Renesas is a 48-pin LFQFP, 96 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104GFAFB#10 datasheet, R5F104GFAFB#10 pinout, R5F104GFAFB#10 application, or R5F104GFAFB#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, 96 KB code flash + 12 KB RAM configuration, -40°C to +105°C industrial temperature grade (G), integrated 10-bit ADC (20 ch), dual UART/LIN support, and real-time clock with calendar function.
Technical Context
The R5F104GFAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) and supports background data flash rewriting (BGO) with 1M-cycle endurance.
Peripheral integration includes an Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/repeat/chain transfer modes, and dual 16-bit Timer Array Units (TAU) plus dedicated RTC, watchdog, and interval timers - enabling deterministic low-latency response in closed-loop industrial control.
