Product details
Overview
R5F100FJDFP#X0 from Renesas is a 44-pin LQFP-44, 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for industrial control, sensor nodes, and battery-powered HMI. It integrates 12-bit ADC (24 channels), RTC, UART/SPI/I²C interfaces, and operates from 1.6–5.5 V across –40°C to +85°C.
For engineers reviewing the R5F100FJDFP#X0 datasheet, R5F100FJDFP#X0 pinout, R5F100FJDFP#X0 application, or R5F100FJDFP#X0 equivalent, key selection criteria include its 96 KB code flash with self-programming, 8 KB data flash with background operation (BGO), 24-channel 12-bit ADC, and support for STOP/HALT/SNOOZE low-power modes in industrial-grade packaging.
Technical Context
The R5F100FJDFP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It features dual-clock domain operation: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) for main system timing and dedicated low-speed oscillator for watchdog/RTC. Power management includes on-chip POR, 14-level LVD with interrupt/reset options, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.

How many analog input channels does the R5F100FJDFP#X0 ADC support?
The R5F100FJDFP#X0 integrates a 12-bit successive-approximation ADC with up to 24 analog input channels (ANI0–ANI23), configurable across multiple ports. It includes an internal 1.45 V reference voltage and temperature sensor, both selectable only in high-speed (HS) main mode per the datasheet.
What low-power modes are available on the R5F100FJDFP#X0, and what is the lowest current consumption?
The R5F100FJDFP#X0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.57 μA typical at VDD = 3.0 V and TA = 25°C. Active-mode current is 66 μA/MHz, making it suitable for battery-critical applications like wireless sensors and portable instrumentation.
Is the R5F100FJDFP#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100FJDFP#X0 is fully pin-compatible with all 44-pin LQFP RL78/G13 devices sharing the PLQP0044GC-A package-including R5F101FJDFP#X0 (no data flash) and R5F100GJDFP#X0 (128 KB flash)-enabling drop-in replacement within the same footprint and peripheral configuration.
