Product details
Overview
R5F104FCDFP#30 from Renesas is a 44-pin LQFP-packaged RL78/G14 16-bit microcontroller with 16 KB flash, 2.5 KB RAM, and industrial-grade -40°C to +85°C operation. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/LIN, I²C, SPI, RTC, and on-chip debug for embedded control in metering and sensor nodes.
For engineers reviewing the R5F104FCDFP#30 datasheet, R5F104FCDFP#30 pinout, R5F104FCDFP#30 application, or R5F104FCDFP#30 equivalent, key selection criteria include its 44-pin LQFP-0.8mm package, 16 KB flash/2.5 KB RAM memory configuration, industrial temperature rating, and integrated analog peripherals enabling compact low-power sensing designs without external signal conditioning.
Technical Context
The R5F104FCDFP#30 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 supports background data flash rewriting (BGO) and self-programming with boot swapping, enabling field firmware updates without halting execution.
Its peripheral set includes Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, real-time clock with calendar/alarm, watchdog timer, and Event Link Controller (ELC) for hardware-triggered peripheral chaining-reducing CPU overhead in deterministic timing applications like motor control and power conversion.

FAQ
What is the maximum operating frequency and associated performance of the R5F104FCDFP#30?
The R5F104FCDFP#30 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over VDD=1.8–5.5 V, TA=–20°C to +85°C), delivering 44 DMIPS. Its RL78 CPU core features a 3-stage pipeline and supports multiply/divide instructions, enabling efficient execution of control algorithms and communication stacks without external clock sources.
Does the R5F104FCDFP#30 support in-system programming and secure firmware updates?
Yes, the R5F104FCDFP#30 includes on-chip debug functionality and supports self-programming with boot swapping and flash shield window protection. This allows secure firmware updates in the field without requiring external programmers, and prevents unauthorized access to code flash contents through hardware-enforced block erase/write prohibition.
What analog peripherals are integrated into the R5F104FCDFP#30 and how are they configured?
The R5F104FCDFP#30 integrates a 10-bit ADC with 16 input channels (ANI0–ANI7, ANI16–ANI19), internal 1.45 V reference voltage, and an on-chip temperature sensor. Analog inputs are routed through dedicated pins (e.g., P20–P27), and the ADC supports single-ended or differential measurement modes with programmable sample-and-hold timing.
How does the R5F104FCDFP#30 achieve ultra-low power consumption in battery-powered applications?
The R5F104FCDFP#30 achieves ultra-low power via multiple low-power modes: HALT (CPU stopped, peripherals active), STOP (all clocks halted except RTC/LVD), and SNOOZE (selected peripherals active while CPU sleeps). In STOP mode with RTC + LVD enabled, it draws only 0.60 μA - enabling multi-year operation on coin-cell batteries in wireless sensor nodes.
Is the R5F104FCDFP#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 44-pin LQFP-0.8mm package (e.g., R5F104BCDFP#30, R5F104GCDFP#30) share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint for memory or peripheral scaling - provided software is updated to match the target variant's flash/RAM size and feature enablement.
