Product details
Overview
R5F100FCGFP#50 from Renesas is a 44-pin LQFP-44, 96 KB flash, 8 KB data flash, 4 KB RAM RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100FCGFP#50 datasheet, R5F100FCGFP#50 pinout, R5F100FCGFP#50 application, or R5F100FCGFP#50 equivalent, key selection criteria include its integrated 10-bit ADC (24 channels), real-time clock with calendar/alarm, UART/LIN support, and industrial-grade temperature range (−40°C to +105°C) in LFQFP packaging.
Technical Context
The R5F100FCGFP#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), DMA controller (4 channels), and hardware multiplier/divider for efficient signal processing.
Its peripheral set includes up to 4 UART/LIN interfaces, 10 I²C/Simplified I²C channels, 16 16-bit timers, a 12-bit interval timer, and a calendar-capable RTC - all optimized for deterministic real-time operation in resource-constrained embedded systems without external timing components.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100FCGFP#50?
The R5F100FCGFP#50 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core efficiency under typical compiler-optimized code execution, enabling real-time tasks such as sensor fusion and communication protocol handling without external acceleration.
Does the R5F100FCGFP#50 support background data flash rewriting while executing application code?
Yes, the R5F100FCGFP#50 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from program memory concurrently with data flash erase/write operations - critical for maintaining system responsiveness during firmware updates or parameter logging.
What is the industrial temperature grade and supply voltage range supported by the R5F100FCGFP#50?
The R5F100FCGFP#50 is rated for −40°C to +105°C (G-grade industrial) and operates across a wide 1.6 V to 5.5 V supply range. This enables deployment in demanding environments such as factory automation, outdoor metering, and motor drives without external voltage regulation or thermal derating.
How many analog input channels and what ADC resolution does the R5F100FCGFP#50 provide?
The R5F100FCGFP#50 integrates a 10-bit successive-approximation ADC with up to 24 analog input channels. It includes an internal 1.45 V reference and temperature sensor, supporting both single-ended and differential measurements - eliminating need for external references in most sensing applications.
Is the R5F100FCGFP#50 pin-compatible with other RL78/G13 variants in the same LQFP-44 package?
Yes, all RL78/G13 devices in the 44-pin LQFP package (e.g., R5F100ECGFP#50, R5F100GCGFP#50) share identical pinouts and electrical characteristics. This allows scalable design reuse - for example, upgrading flash size or RAM without PCB revision - provided software accounts for memory map differences.
