Product details
Overview
R5F100FDGFP#50 from Renesas is a 44-pin LQFP-44, 5 V-tolerant RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, integrated RTC and low-power STOP mode (0.57 μA), designed for industrial control panels requiring deterministic real-time response and extended battery-backed operation.
For engineers reviewing the R5F100FDGFP#50 datasheet, R5F100FDGFP#50 pinout, R5F100FDGFP#50 application, or R5F100FDGFP#50 equivalent, key selection criteria include its 44-pin LQFP package with 32 I/Os, 10-bit ADC (24 channels), dual UART/LIN support, and industrial-grade temperature range (−40°C to +105°C) under G-grade qualification.
Technical Context
The R5F100FDGFP#50 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, calendar-based RTC with alarm and clock correction, and on-chip voltage detector with 14-level LVD interrupt/reset selection.
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, 8–16 16-bit timers, and a 2-channel DMA controller enabling zero-wait-state transfers between SFR and RAM in just two clocks - critical for deterministic sensor data acquisition and motor control loop timing.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100FDGFP#50?
The R5F100FDGFP#50 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs in this mode, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - enabling precise trade-offs between throughput and energy consumption in the R5F100FDGFP#50.
Does the R5F100FDGFP#50 support in-system programming and secure firmware updates?
Yes, the R5F100FDGFP#50 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features for IP protection. Its self-programming capability with boot swap function ensures safe over-the-air or field firmware updates - a core reliability feature built into the R5F100FDGFP#50 architecture.
How many analog input channels does the R5F100FDGFP#50 provide, and what resolution is supported?
The R5F100FDGFP#50 integrates a 10-bit successive approximation A/D converter with up to 24 analog input channels (ANI0–ANI23), selectable from multiple port pins. It includes an internal 1.45 V reference voltage and supports differential input modes - providing calibrated, low-noise measurement capability directly within the R5F100FDGFP#50 without external components.
What low-power modes are available on the R5F100FDGFP#50, and what functions remain active in STOP mode?
The R5F100FDGFP#50 offers HALT, STOP, and SNOOZE modes. In STOP mode, only the RTC, LVD, and reset circuit remain active - drawing just 0.57 μA typical. This allows long-term timekeeping and brown-out monitoring while all other peripherals and CPU clocks are halted, making STOP mode ideal for battery-critical applications using the R5F100FDGFP#50.
Is the R5F100FDGFP#50 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 44-pin LQFP package (e.g., R5F100FDGFP#50, R5F100FGGFP#50, R5F101FDGFP#50) share identical pinouts and electrical characteristics. This enables direct substitution during design-in or production ramp - allowing firmware and layout reuse across flash/RAM variants while maintaining full compatibility with the R5F100FDGFP#50 footprint.
