Product details
Overview
R5F104JFGFA#30 from Renesas is a 52-pin LQFP-0.65mm-pitch 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and industrial-grade -40°C to +105°C operation (G-grade). It integrates 16-bit TAU timers, 10-bit ADC (16 channels), UART/LIN, I²C, SPI, RTC, and ultra-low-power HALT/STOP/SNOOZE modes - deployed in motor control subsystems for HVAC actuators.
For engineers reviewing the R5F104JFGFA#30 datasheet, R5F104JFGFA#30 pinout, R5F104JFGFA#30 application, or R5F104JFGFA#30 equivalent, key selection criteria include its G-grade temperature rating, 52-pin LQFP package with 0.65 mm pitch, 96 KB code flash with data flash shield window, and support for background data flash rewriting (BGO) at VDD = 1.8–5.5 V.
Technical Context
The R5F104JFGFA#30 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). Its peripheral set includes Event Link Controller (ELC) for hardware-triggered peripheral chaining and Data Transfer Controller (DTC) with block/chain transfer modes activated by interrupt sources.
It features dual clock domains: high-speed on-chip oscillator (selectable 64–1 MHz, ±1.0% accuracy) and subsystem clock (e.g., 32.768 kHz RTC). Power management includes on-chip POR, 14-level LVD with interrupt/reset options, and true low-power operation down to 0.60 µA in RTC+LVD-only mode.
