Product details
Overview
R5F104JFGFA#V0 from Renesas is a 52-pin LQFP-0.65 mm pitch, industrial-grade (G) RL78/G14 16-bit microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, and operation from −40°C to +105°C. It integrates a 32-MHz RL78 CPU core (44 DMIPS), 12-bit ADC (20 channels), dual DAC, RTC, 8-channel 16-bit timers, UART/SPI/I²C interfaces, and ultra-low-power modes (0.60 μA in STOP with RTC+LVD).
For engineers reviewing the R5F104JFGFA#V0 datasheet, R5F104JFGFA#V0 pinout, R5F104JFGFA#V0 application, or R5F104JFGFA#V0 equivalent, this page delivers verified electrical specs, package mapping, functional role in sensor hubs and motor control, and two validated alternative parts for design flexibility.
Technical Context
The R5F104JFGFA#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It supports on-chip debug, self-programming with boot swap, and background operation during data flash rewriting.
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 voltage comparators with window mode - all operating within 1.6–5.5 V supply range and qualified for industrial ambient temperatures up to +105°C.
