Product details
Overview
R5F104PGAFA#V0 from Renesas is a 44-pin LQFP-0.8 mm 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 A-grade), featuring ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), 32 MHz max CPU speed (44 DMIPS), and integrated peripherals including 10-bit ADC (20 ch), UART/LIN (4 ch), I²C (10 ch), and 16-bit timers (12 ch).
For engineers reviewing the R5F104PGAFA#V0 datasheet, R5F104PGAFA#V0 pinout, R5F104PGAFA#V0 application, or R5F104PGAFA#V0 equivalent, key selection criteria include industrial temperature support, 44-pin LQFP package compatibility, 96 KB code flash with data flash retention, low-power real-time clock operation, and peripheral mix for sensor interface, motor control, and LIN bus communication.
Technical Context
The R5F104PGAFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and includes multiply/divide/accumulate instructions. It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–64 MHz) and supports HALT/STOP/SNOOZE low-power modes.
Peripheral subsystems include an Event Link Controller (ELC) enabling 19–26 event sources to trigger peripheral functions without CPU intervention, a Data Transfer Controller (DTC) with chain transfer capability, and background operation (BGO) for data flash rewriting while executing program code - critical for firmware updates in field-deployed devices.

Yes, the R5F104PGAFA#V0 supports LIN bus communication on UART channels 0 through 3. The hardware includes LIN-specific features such as automatic sync-field detection, break detection, and configurable baud rates per channel - confirmed in Section 1.1 "Features" and UART functional description of the R01DS0053EJ0340 datasheet.
What is the data flash endurance and voltage range for reprogramming the R5F104PGAFA#V0?
The R5F104PGAFA#V0 provides 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) with reprogramming supported across the full supply range of VDD = 1.8 V to 5.5 V - enabling reliable field updates even in brown-out conditions, as specified in the "Data Flash Memory" section of R01DS0053EJ0340.
How many analog input channels does the R5F104PGAFA#V0 support, and what ADC resolution is available?
The R5F104PGAFA#V0 integrates a 10-bit successive-approximation ADC supporting up to 20 analog input channels (ANI0–ANI19), with selectable internal 1.45 V reference voltage and on-die temperature sensor - all accessible in the 44-pin LQFP package per pin configuration diagrams on pages 13–14 of R01DS0053EJ0340.
Is the R5F104PGAFA#V0 pin-compatible with other RL78/G14 variants in the same 44-pin LQFP package?
