Product details
Overview
R5F104PFAFB#V0 from Renesas is a 100-pin LFQFP, 0.5 mm pitch, industrial-grade (G) RL78/G14 16-bit microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), and integrates 10-channel 10-bit ADC, dual UART/LIN, I²C, CSI, 12-channel 16-bit timers, RTC, and on-chip debug.
For engineers reviewing the R5F104PFAFB#V0 datasheet, R5F104PFAFB#V0 pinout, R5F104PFAFB#V0 application, or R5F104PFAFB#V0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, G-grade temperature rating, integrated LIN-capable UARTs for automotive body control, and real-time data flash BGO operation supporting field firmware updates without halting execution.
Technical Context
The R5F104PFAFB#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 supports multiply/divide/MAC instructions and 1 MB address space across four register banks.
Its peripheral set includes Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/repeat/chain transfer modes, and dual independent UART channels with LIN bus support-enabling deterministic serial communication in noise-prone industrial environments.

FAQ
What is the maximum operating frequency and power consumption of the R5F104PFAFB#V0?
The R5F104PFAFB#V0 operates at up to 32 MHz (44 DMIPS) with a high-accuracy on-chip oscillator (±1.0%). Its ultra-low-power design achieves 66 μA/MHz in HALT mode and just 0.60 μA in STOP mode with RTC and LVD active-making it ideal for battery-backed industrial and automotive applications where standby current is critical. These values are measured per Renesas R01DS0053EJ0370 specifications.
Does the R5F104PFAFB#V0 support LIN bus communication, and how is it implemented?
Yes, the R5F104PFAFB#V0 supports LIN bus communication through two dedicated UART channels that meet LIN 2.2 physical layer requirements-including automatic sync-break detection, configurable baud rates, and hardware support for LIN header/response timing. Each UART can operate independently as LIN master or slave, enabling dual-bus architectures in automotive body control modules without external transceivers.
What are the flash memory configuration and security features of the R5F104PFAFB#V0?
The R5F104PFAFB#V0 contains 96 KB of code flash memory organized in 1 KB blocks, with programmable block erase/write prohibition for IP protection. It also includes 8 KB of data flash supporting background operation (BGO), allowing firmware or calibration data updates while the CPU executes from program memory. Security features include flash shield window, on-chip debug lock, and prohibition of unauthorized block erasure-verified in Renesas' flash programming documentation.
How many analog-to-digital converter (ADC) channels does the R5F104PFAFB#V0 provide, and what is its resolution?
The R5F104PFAFB#V0 integrates a 10-bit successive-approximation ADC with up to 10 analog input channels. It supports internal reference voltage (1.45 V), temperature sensor readout, and selectable sample-and-hold timing. The ADC operates across the full 1.6–5.5 V supply range and is validated for precision sensor interfacing in industrial and automotive applications per the RL78/G14 datasheet.
What is the operating temperature range and qualification grade for the R5F104PFAFB#V0?
The R5F104PFAFB#V0 is qualified for industrial applications with an operating ambient temperature range of -40°C to +105°C (G-grade). This rating is confirmed by Renesas' ordering code suffix "G" and applies to the full functional specification-including flash endurance, ADC accuracy, and oscillator stability-under continuous operation within this thermal envelope.
