Product details
Overview
R5F104FCGFP#30 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G14 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), featuring ultra-low-power HALT/STOP/SNOOZE modes, integrated RTC, 10-bit ADC (16 channels), and UART/I²C/CSI interfaces for industrial sensor control and smart appliance applications.
For engineers reviewing the R5F104FCGFP#30 datasheet, R5F104FCGFP#30 pinout, R5F104FCGFP#30 application, or R5F104FCGFP#30 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature range (G-suffix), 0.6 µA RTC+LVD standby current, 16-channel analog input capability, and LFQFP-44 package compatibility with legacy Renesas RL78 toolchains and debug adapters.
Technical Context
The R5F104FCGFP#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), plus multiply/divide/accumulate instructions and 1 MB address space. It integrates a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) and supports background data flash rewriting (1M write cycles, 1.8–5.5 V).
Peripheral integration includes Timer Array Unit (TAU) with 8 channels, Real-time Clock with calendar/alarm/correction, 12-bit interval timer, watchdog timer, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention-critical for deterministic low-latency response in motor control and power management systems.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104FCGFP#30?
The R5F104FCGFP#30 operates at up to 32 MHz with a measured performance of 44 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set-including multiply/divide/accumulate operations-enabling deterministic real-time execution in motor control and sensor fusion applications where cycle count predictability is essential.
Does the R5F104FCGFP#30 support hardware debugging and programming in-system?
Yes, the R5F104FCGFP#30 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. It supports full-speed debugging, flash programming via SWD interface, and real-time trace via TOOL0/TOOLRxD/TOOLTxD pins-enabling non-intrusive development and validation without requiring external debug probes beyond standard JTAG/SWD adapters.
What are the analog input capabilities of the R5F104FCGFP#30, including channel count and reference options?
The R5F104FCGFP#30 features a 10-bit successive-approximation ADC with 16 analog input channels (ANI0–ANI19, excluding reserved pins). It supports internal 1.45 V reference voltage, external reference via AVREFP/AVREFM pins, and integrated temperature sensor-all usable simultaneously with programmable sampling timing and scan sequence control for multi-sensor acquisition.
How does the R5F104FCGFP#30 manage ultra-low-power operation in STOP mode?
The R5F104FCGFP#30 achieves 0.6 µA STOP mode current by disabling the main CPU, flash, and most peripherals while retaining RTC operation, LVD monitoring, and INTP0 wake-up capability. The internal low-voltage regulator remains active, and the 32.768 kHz subsystem clock continues running-allowing precise timekeeping and fast wake-up (< 4 µs) for responsive event-driven operation in battery-constrained designs.
Is the R5F104FCGFP#30 pin-compatible with other RL78/G14 variants in the 44-pin LQFP package?
Yes, all RL78/G14 44-pin LQFP variants-including R5F104FCGFP#30, R5F104FGGFP#30, and R5F104GCGFP#30-share identical pinout, electrical characteristics, and package dimensions (PLQP0044GC-A). This enables direct hardware reuse across memory variants, simplifying design scalability and reducing qualification effort when upgrading flash/RAM capacity.
