Product details
Overview
R5F104FJGFP#30 from Renesas is a 44-pin LQFP-packaged RL78/G14 16-bit microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at up to 32 MHz (44 DMIPS), targeting low-power industrial control and sensor interface applications.
For engineers reviewing the R5F104FJGFP#30 datasheet, R5F104FJGFP#30 pinout, R5F104FJGFP#30 application, or R5F104FJGFP#30 equivalent, this page delivers verified electrical specs, validated I/O mapping, real-world use cases in temperature monitoring and motor control, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The R5F104FJGFP#30 implements the RL78 CPU core with 3-stage pipeline, 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 12-bit interval timer, RTC with calendar/alarm, and watchdog timer driven by dedicated low-speed oscillator.
Peripheral integration includes 10-channel 10-bit A/D converter (8–20 inputs), dual 8-bit D/A outputs, up to 12× 16-bit timers (TAU, RJ, RD, RG), 3–4 UART/LIN channels, 4–10 I²C interfaces, and 3–8 CSI/SPI channels-all managed via Event Link Controller (ELC) for hardware-triggered peripheral chaining without CPU intervention.

Does the R5F104FJGFP#30 support background data flash rewriting (BGO), and what is its endurance specification?
Yes, the R5F104FJGFP#30 supports background data flash rewriting (BGO), allowing CPU code execution from program memory while data flash is being rewritten. Its data flash endurance is rated at 1,000,000 write/erase cycles (typical), with guaranteed operation across the full 1.8–5.5 V VDD range-enabling reliable field updates in maintenance-free deployments.
What are the key power-saving modes supported by the R5F104FJGFP#30, and what is its lowest achievable current draw?
The R5F104FJGFP#30 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.60 μA typical current draw at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables decade-long operation on primary lithium batteries in remote monitoring applications.
