Product details
Overview
R5F104BFAFP#V0 from Renesas is a 32-pin LQFP-0.8mm-pitch 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 (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (16 ch), RTC, and on-chip debug.
For engineers reviewing the R5F104BFAFP#V0 datasheet, R5F104BFAFP#V0 pinout, R5F104BFAFP#V0 application, or R5F104BFAFP#V0 equivalent, key selection criteria include its industrial temperature rating, integrated data flash with 1M rewrite cycles, background operation capability, and support for LIN-bus via UART - critical for motor control, sensor hubs, and industrial HMI designs.
Technical Context
The R5F104BFAFP#V0 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 embeds a high-accuracy ±1.0% on-chip oscillator (selectable 1–64 MHz) and supports event-driven processing via Event Link Controller (ELC) linking up to 26 peripheral events without CPU intervention.
Power management includes on-chip POR and 14-level LVD with interrupt/reset options; memory subsystem enables self-programming with boot swap and flash shield window, while Data Transfer Controller (DTC) supports block/repeat/chain transfers triggered by interrupts - enabling efficient sensor data acquisition and real-time firmware updates.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104BFAFP#V0?
The R5F104BFAFP#V0 operates at up to 32 MHz, delivering 44 DMIPS of processing performance. Its high-accuracy ±1.0% on-chip oscillator eliminates need for external crystal in many applications, and instruction timing is configurable from 0.03125 μs (high-speed mode) to 30.5 μs (ultra-low-speed mode) - enabling dynamic power/performance scaling. This makes the R5F104BFAFP#V0 well-suited for deterministic real-time tasks in industrial control loops.
Does the R5F104BFAFP#V0 support LIN bus communication, and how is it implemented?
Yes, the R5F104BFAFP#V0 supports LIN bus communication through its UART peripherals, which include dedicated LIN-mode functionality. The UART modules support automatic LIN header detection, checksum calculation (classic and enhanced), and synchronization break detection per ISO 9141-2 and LIN 2.x standards. This capability is implemented in hardware - requiring no bit-banging or CPU-intensive software emulation - making the R5F104BFAFP#V0 ideal for automotive body electronics and industrial sub-node networks.
What are the data flash endurance and write characteristics of the R5F104BFAFP#V0?
The R5F104BFAFP#V0 includes 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) across full VDD range (1.8–5.5 V). It supports background operation (BGO), allowing program execution from code flash while data flash is being rewritten - critical for uninterrupted logging and configuration updates. The R5F104BFAFP#V0 also provides flash shield window and block erase prohibition features to protect critical calibration or security data from accidental overwrite.
How does the R5F104BFAFP#V0 achieve ultra-low power consumption in STOP mode?
The R5F104BFAFP#V0 achieves 0.60 μA typical current consumption in 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 dedicated low-speed on-chip oscillator. Wake-up can occur via RTC alarm, LVD event, or external interrupt - all without full system restart. This behavior is confirmed in the RL78/G14 datasheet (R01DS0053EJ0340) and makes the R5F104BFAFP#V0 suitable for battery-powered applications requiring multi-year operation.
Is the R5F104BFAFP#V0 pin-compatible with other RL78/G14 variants in the same package?
Yes, the R5F104BFAFP#V0 is fully pin-compatible with all other 32-pin LQFP-0.8mm RL78/G14 variants including R5F104BEAFP#V0 and R5F104BGAFP#V0. All share identical pin configuration, electrical characteristics, and peripheral mapping - enabling drop-in memory scalability during design iteration or production ramp. This compatibility is documented in Renesas' RL78/G14 ordering information (Table 1-1, R01DS0053EJ0340) and verified across hardware layout and firmware abstraction layers for the R5F104BFAFP#V0.
