Product details
Overview
R5F104FFGFP#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 -40 to +85°C (industrial grade D). It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), and integrates 12-bit RTC, 10-bit ADC (16 ch), UART/I²C/CSI interfaces, and on-chip debug.
For engineers reviewing the R5F104FFGFP#30 datasheet, R5F104FFGFP#30 pinout, R5F104FFGFP#30 application, or R5F104FFGFP#30 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific role definitions, and two confirmed alternative parts for industrial control, sensor hub, and battery-powered HMI designs.
Technical Context
The RL78 CPU core uses a 3-stage CISC pipeline with configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz) and supports multiply/divide/MAC instructions. Its memory map spans 1 MB with four register banks (8×8-bit), enabling efficient context switching in interrupt-driven embedded systems.
Peripherals include an Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) supporting block/repeat/chain transfers, and dual-voltage operation (1.6–5.5 V) with on-chip POR and 14-level LVD-enabling robust operation across wide supply and temperature ranges in industrial environments.

FAQ
What is the maximum operating frequency and associated performance of the R5F104FFGFP#30?
The R5F104FFGFP#30 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over -20 to +85°C), delivering 44 DMIPS. This performance level supports real-time tasks such as 10 kHz PWM generation, 100 Hz sensor fusion, and lightweight TCP/IP stacks without external acceleration.
Does the R5F104FFGFP#30 support background data flash rewriting while executing application code?
Yes, the R5F104FFGFP#30 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from program memory during erase/write cycles-critical for maintaining deterministic response in motor control or communication protocols where latency must stay below 10 µs.
What are the power consumption characteristics of the R5F104FFGFP#30 in low-power modes?
The R5F104FFGFP#30 achieves 0.60 μA in STOP mode with RTC and LVD active, 66 μA/MHz in HALT mode, and supports SNOOZE mode for selective peripheral operation. These values are measured at VDD = 1.8 V, TA = 25°C, and enable >5-year operation on a single CR2032 in periodic wake-up sensor applications.
Which serial communication interfaces are available on the R5F104FFGFP#30, and how are they allocated?
The R5F104FFGFP#30 provides 3 UART/LIN channels, 4–10 I²C channels, and 3–8 CSI (SPI-compatible) channels. Pins P60/P61 are dedicated to I²C0; P10–P15 support configurable CSI/I²C/UART functions via peripheral I/O redirection registers (PIOR0/1), enabling runtime interface remapping without PCB changes.
Is the R5F104FFGFP#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 44-pin LQFP (PLQP0044GC-A) package-including R5F104FAAFP#30 through R5F104FJGFP#30-share identical pinouts and electrical characteristics. This allows direct substitution within the same memory/feature tier (e.g., R5F104FFGFP#30 ↔ R5F104FGAFP#30) when upgrading flash/RAM capacity.
