Product details
Overview
R5F104FCGFP#10 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G14 microcontroller with 16 KB flash, 2.5 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V at -40 to +105°C (industrial G-grade), delivering 44 DMIPS at 32 MHz for low-power embedded control in motor drives, sensor nodes, and industrial HMI.
For engineers reviewing the R5F104FCGFP#10 datasheet, R5F104FCGFP#10 pinout, R5F104FCGFP#10 application, or R5F104FCGFP#10 equivalent, key selection considerations include its 44-pin LQFP-0.8 mm pitch package, integrated RTC + LVD + BGO data flash, 10-bit 20-channel ADC, and support for UART/LIN, I²C, and CSI serial interfaces in thermally demanding environments.
Technical Context
The R5F104FCGFP#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-power mode), and includes multiply/divide/accumulate instructions within a 1 MB address space.
It integrates a 12-bit interval timer, real-time clock with calendar/alarm/correction, watchdog timer, and Event Link Controller (ELC) supporting up to 26 event sources linked to peripherals-enabling deterministic low-latency response without CPU intervention for time-critical I/O sequencing.

FAQ
What is the maximum operating temperature range for the R5F104FCGFP#10?
The R5F104FCGFP#10 is rated for industrial G-grade operation from -40 to +105°C, verified per Renesas specification R01DS0053EJ0370. This extended range supports deployment in harsh environments such as motor drive enclosures, factory-floor controllers, and outdoor sensor housings where ambient temperatures exceed standard commercial limits. The R5F104FCGFP#10 maintains full functionality-including ADC accuracy, RTC stability, and flash write endurance-across this full range.
Does the R5F104FCGFP#10 support in-system programming via its UART interface?
Yes, the R5F104FCGFP#10 supports bootloader-based in-system programming using UART channel 0 (P50/P51), enabled by the on-chip debug interface and flash self-programming library. The R5F104FCGFP#10 requires no external programmer for field firmware updates, provided the boot swap function is configured and the UART pins are accessible. Renesas Application Note R20AN0207 confirms UART-based flashing with error-checking and secure boot validation.
How many I²C interfaces does the R5F104FCGFP#10 include, and are they fully independent?
The R5F104FCGFP#10 includes four independent I²C/simplified I²C channels (designated SCLA0/SDAA0, SCL11/SDA11, SCL20/SDA20, SCL21/SDA21), each with dedicated hardware controllers, separate clock/data pins, and autonomous start/stop/ACK handling. All four channels operate concurrently without resource contention, enabling simultaneous communication with multiple sensors, EEPROMs, or display drivers-critical for multi-peripheral industrial systems using the R5F104FCGFP#10.
Can the R5F104FCGFP#10's data flash be rewritten while the CPU executes code from main flash?
Yes, the R5F104FCGFP#10 supports Background Operation (BGO) for data flash, allowing full CPU execution from code flash memory during 4 KB data flash erase/write cycles. This capability eliminates interrupt latency spikes and enables real-time logging, calibration storage, or configuration updates without disrupting control loops-a confirmed feature documented in Section 1.1 "Features" of the R5F104FCGFP#10 datasheet R01DS0053EJ0370.
What is the purpose of the REGC pin on the R5F104FCGFP#10, and how must it be connected?
The REGC pin on the R5F104FCGFP#10 connects to an external 0.47–1.0 µF capacitor tied to VSS, stabilizing the internal voltage regulator that powers the analog and RTC circuits. Per Section 1.3.5 of the R5F104FCGFP#10 datasheet, improper REGC decoupling causes erratic ADC readings, RTC drift, or failure to enter STOP mode. This capacitor must be placed within 3 mm of the REGC and VSS pins, using low-ESR ceramic dielectric-no alternative connection or omission is permitted for reliable R5F104FCGFP#10 operation.
