Product details
Overview
R5F104FGGFP#50 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and industrial-grade -40°C to +105°C operation (G-grade), featuring ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), integrated 10-bit ADC (20 channels), UART/SPI/I²C interfaces, and real-time clock for embedded control in HVAC, motor drives, and industrial sensors.
For engineers reviewing the R5F104FGGFP#50 datasheet, R5F104FGGFP#50 pinout, R5F104FGGFP#50 application, or R5F104FGGFP#50 equivalent, key selection considerations include its G-grade temperature rating, 44-pin LQFP-0.8 mm pitch package, 96 KB code flash with data flash support, and peripheral set optimized for cost-sensitive industrial control with low-power operation and on-chip debugging.
Technical Context
The R5F104FGGFP#50 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 integrates a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) and supports HALT/STOP/SNOOZE low-power modes.
Peripheral integration includes Timer Array Unit (TAU) with up to 8 channels, 1-channel real-time clock with calendar/alarm, 1-channel watchdog timer, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention-critical for deterministic response in motor control and sensor polling.

FAQ
What is the maximum operating frequency of the R5F104FGGFP#50?
The R5F104FGGFP#50 supports up to 32 MHz operation using the high-speed on-chip oscillator, delivering 44 DMIPS performance. Its minimum instruction execution time is 0.03125 µs at 32 MHz, and it can scale down to 32.768 kHz for ultra-low-power RTC operation with 30.5 µs instruction time-enabling dynamic frequency scaling based on workload.
Does the R5F104FGGFP#50 support in-system programming (ISP)?
Yes, the R5F104FGGFP#50 supports in-system programming via its on-chip debug interface and self-programming capability. It features boot swapping and flash shield window protection, allowing secure firmware updates in the field without requiring external programmers-critical for remote industrial equipment maintenance.
How many UART channels does the R5F104FGGFP#50 include, and do they support LIN bus?
The R5F104FGGFP#50 includes three UART channels, all of which support LIN bus physical layer compliance (LIN 2.2A). Each UART can operate as master or slave, with built-in break detection, sync field handling, and checksum calculation-enabling direct integration into automotive body control modules or industrial sub-networks.
What is the purpose of the REGC pin on the R5F104FGGFP#50, and how must it be connected?
The REGC pin on the R5F104FGGFP#50 is the bypass capacitor terminal for the internal voltage regulator. It must be connected to VSS via a 0.47 µF to 1 µF ceramic capacitor to ensure stable operation of the analog circuitry, RTC, and LVD-failure to do so may cause erratic ADC readings, RTC drift, or reset instability under load transients.
Can the R5F104FGGFP#50 operate from a single 1.8 V supply, and what peripherals remain functional?
Yes, the R5F104FGGFP#50 operates from 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, the CPU, 96 KB flash, 12 KB RAM, 10-bit ADC (with internal 1.45 V reference), RTC, and low-speed peripherals (I²C, UART) remain fully functional-enabling direct interface with 1.8 V logic families and energy-harvesting power sources without level translation.
