Product details
Overview
R5F104GJGFB#V0 from Renesas is a 48-pin LFQFP, 96 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104GJGFB#V0 datasheet, R5F104GJGFB#V0 pinout, R5F104GJGFB#V0 application, or R5F104GJGFB#V0 equivalent, key selection criteria include its industrial-grade temperature range (−40 to +105°C), integrated 10-bit 20-channel ADC, dual UART/LIN support, and hardware DTC/ELC for deterministic peripheral event handling without CPU intervention.
Technical Context
The R5F104GJGFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-power mode), and includes multiply/divide/accumulate instructions with 1 MB address space.
It integrates a configurable Event Link Controller (ELC) linking up to 26 peripheral event sources directly to functions like timer triggers or ADC starts, and a Data Transfer Controller (DTC) enabling block, repeat, and chain transfers activated by interrupts-reducing CPU load during data movement.

FAQ
What is the maximum operating temperature specification for the R5F104GJGFB#V0?
The R5F104GJGFB#V0 is rated for industrial operation from −40°C to +105°C, as indicated by the 'G' suffix in the part number. This allows deployment in demanding environments such as enclosed industrial controls, outdoor utility meters, and under-hood automotive body modules where ambient temperatures exceed standard consumer-grade limits.
Does the R5F104GJGFB#V0 support in-system programming via its UART interface?
Yes, the R5F104GJGFB#V0 supports in-system programming using the on-chip UART bootloader. It requires no external programmer-only a UART connection and the Renesas Flash Development Toolkit (FDT) or compatible host software. The bootloader resides in ROM and remains accessible even after flash security lock activation.
How many independent UART/LIN interfaces does the R5F104GJGFB#V0 provide?
The R5F104GJGFB#V0 provides three UART channels, all with LIN-bus physical layer support including automatic sync-break detection and LIN header generation. These are implemented on P00/P01 (UART0), P16/P17 (UART1), and P13/P14 (UART2), each configurable via peripheral I/O redirection registers.
Is an external crystal required for real-time clock operation in the R5F104GJGFB#V0?
No-the R5F104GJGFB#V0 includes a built-in 32.768 kHz sub-system oscillator for RTC operation, eliminating the need for an external crystal in basic calendar/timekeeping applications. An external 32.768 kHz crystal (X1/X2) may be added for higher accuracy if required by system specifications.
What debug interface does the R5F104GJGFB#V0 use, and what pins are involved?
The R5F104GJGFB#V0 uses the Renesas FINE (Fast In-Circuit Emulator) debug interface, which operates over two dedicated pins: P40 (TOOL0) and P50/P51 (TOOLRxD/TOOLTxD). This 2-wire interface supports full JTAG-like debugging-including breakpoints, watchpoints, and memory access-without requiring additional debug headers or SWD pins.
