Product details
Overview
R5F104GFGNA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and industrial-grade operation up to +105°C. It integrates a 32 MHz RL78 CPU core (44 DMIPS), 10-bit 16-channel ADC, dual 8-bit DACs, RTC with calendar, and ultra-low-power modes (0.60 μA in STOP with RTC+LVD). It targets battery-powered industrial sensors and motor control interfaces requiring deterministic real-time response.
For engineers reviewing the R5F104GFGNA#U0 datasheet, R5F104GFGNA#U0 pinout, R5F104GFGNA#U0 application, or R5F104GFGNA#U0 equivalent, key selection criteria include its 48-pin 7×7 mm HWQFN package with exposed pad, G-grade temperature rating (−40 to +105°C), integrated LIN-capable UARTs, and hardware DTC/ELC for low-CPU-overhead peripheral coordination.
Technical Context
The R5F104GFGNA#U0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It supports multiply/divide/accumulate instructions and features a 1 MB address space with four register banks.
Its peripheral set includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, watchdog timer, and Event Link Controller (ELC) enabling direct hardware linking of 19–26 event sources to peripherals-eliminating CPU polling for time-critical signal routing.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GFGNA#U0?
The R5F104GFGNA#U0 operates at up to 32 MHz with its high-speed on-chip oscillator, delivering 44 DMIPS performance. This benchmark reflects actual instruction throughput under typical code mix conditions-not theoretical peak-and is validated across the full −40°C to +105°C temperature range specified for the G-grade device.
Does the R5F104GFGNA#U0 support LIN bus communication, and which UART channels implement it?
Yes, the R5F104GFGNA#U0 supports LIN 2.2-compliant communication via its UART channels-including UART2 (pins P13/P14) and UART0 (pins P50/P51). The hardware includes automatic sync-break detection, checksum calculation, and frame timeout handling, enabling full LIN slave functionality without CPU overhead.
What are the flash memory organization and security features of the R5F104GFGNA#U0?
The R5F104GFGNA#U0 contains 96 KB of code flash organized in 1 KB blocks, with programmable block erase/write protection and flash shield window functionality. These features prevent unauthorized readout or modification of critical firmware sections-essential for IP protection and functional safety certification.
How does the R5F104GFGNA#U0 achieve 0.60 μA STOP mode current, and what functions remain active?
The R5F104GFGNA#U0 achieves 0.60 μA in STOP mode by disabling the CPU, flash, and most peripherals while retaining power to the RTC, LVD circuit, and wakeup logic. Only the 32.768 kHz subsystem clock runs, sustaining calendar timekeeping, voltage monitoring, and interrupt-triggered wake-up-verified per JEDEC JESD78 test conditions.
Is the R5F104GFGNA#U0 pin-compatible with other RL78/G14 variants in the same 48-pin HWQFN package?
Yes, all RL78/G14 devices in the 48-pin HWQFN package-including R5F104GFGNA#U0, R5F104GGGNA#U0, and R5F104GHGNA#U0-share identical pinouts, electrical characteristics, and mechanical dimensions. This enables drop-in memory upgrades without PCB redesign or layout modification.
