For engineers reviewing the R5F104GFGFB#V0 datasheet, R5F104GFGFB#V0 pinout, R5F104GFGFB#V0 application, or R5F104GFGFB#V0 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature rating (G suffix), integrated 10-bit 20-channel ADC, dual UART/LIN support, and hardware DTC/ELC for deterministic real-time peripheral coordination.
Technical Context
The R5F104GFGFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock), and includes multiply/divide/accumulate instructions within a 1 MB address space.
It integrates a configurable 16-bit Timer Array Unit (TAU) with up to 8 channels, one 12-bit interval timer, calendar-capable real-time clock (RTC), watchdog timer, and event-driven peripherals coordinated via Event Link Controller (ELC) with 19–26 event signal types and Data Transfer Controller (DTC) supporting block/chain transfers.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GFGFB#V0?
The R5F104GFGFB#V0 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 44 DMIPS of processing performance. This rating is measured under standard conditions (VDD = 2.7–5.5 V, TA = 25°C) and reflects the RL78 core's 3-stage pipeline efficiency with optimized instruction mix.
Does the R5F104GFGFB#V0 support LIN bus communication, and which peripheral implements it?
Yes, the R5F104GFGFB#V0 supports LIN bus communication through its UART peripherals-specifically UART0, UART1, and UART2-which include built-in LIN break-detection and sync-field generation logic. The UART modules operate in LIN mode with automatic checksum calculation and header/response timing compliance per LIN 2.x specifications.
What are the data flash endurance and voltage requirements for rewriting the R5F104GFGFB#V0?
The R5F104GFGFB#V0 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) and supports rewriting across the full supply range of VDD = 1.8–5.5 V. Background operation (BGO) allows CPU code execution from program memory during data flash writes, enabling seamless firmware parameter updates without system interruption.
How does the R5F104GFGFB#V0 achieve its 0.60 μA STOP mode current specification?
The R5F104GFGFB#V0 achieves 0.60 μA STOP mode by powering down the CPU, flash, RAM, and most peripherals while retaining operation of the real-time clock (RTC), low-voltage detector (LVD), and associated wakeup circuitry. This configuration enables calendar-based alarms and voltage-monitoring interrupts while minimizing leakage and bias currents in the remaining active blocks.
Is the R5F104GFGFB#V0 pin-compatible with other RL78/G14 variants in the 48-pin LFQFP package?
Yes, the R5F104GFGFB#V0 is fully pin-compatible with all other RL78/G14 devices in the 48-pin LFQFP (FB) package-including R5F104GGGFB#V0, R5F104GHGFB#V0, and R5F104GLGFB#V0-as confirmed by Renesas' official pin configuration diagrams and package drawings (PLQP0048KF-A/KB-B/KL-A). Signal assignments and power/ground pin locations are identical across this package variant.
