Product details
Overview
R5F100FCDFP#50 from Renesas is a 44-pin LQFP-44, 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating at up to 32 MHz with 41 DMIPS performance and ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 10-bit ADC (12 channels), UART/SPI/I²C interfaces, RTC, and operates from 1.6–5.5 V for industrial control and sensor node applications.
For engineers reviewing the R5F100FCDFP#50 datasheet, R5F100FCDFP#50 pinout, R5F100FCDFP#50 application, or R5F100FCDFP#50 equivalent, key selection criteria include its 44-pin LQFP package, 96 KB code flash with self-programming, 10-bit 12-channel ADC, integrated RTC with calendar/alarm, and support for STOP/HALT/SNOOZE low-power states in industrial temperature range (−40°C to +85°C).
Technical Context
The R5F100FCDFP#50 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features on-chip debug, flash shield window, and boot swap functionality for secure firmware updates.
Its peripheral set includes 2–4 channel DMA, 16-bit timer (12 channels), 12-bit interval timer, watchdog timer, and simplified SPI (CSI), UART/LIN, and I²C interfaces - all configurable via register-based control without external clock dependencies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FCAFP#50 | Same 96 KB flash, 8 KB data flash, 8 KB RAM, but uses 44-pin LQFP with 0.8-mm pitch and no data flash protection lock bit enabled by default | Targeted for cost-sensitive consumer designs where flash security is not required | Select when flash shield window and block erase prohibition are unnecessary and lower unit cost is prioritized |
| R5F101FCDFP#50 | Identical pinout and peripherals, but lacks data flash memory (0 KB); retains same 96 KB code flash and 8 KB RAM | Suitable for firmware-only applications without runtime parameter storage needs | Choose when BGO data logging is not required and design can rely solely on external EEPROM or cloud storage |
Compared with R5F100FCDFP#50, R5F100FCAFP#50 offers identical functionality without default flash security features, reducing configuration overhead; R5F101FCDFP#50 removes data flash entirely, lowering cost and power in fixed-parameter deployments where runtime reconfiguration is unnecessary.

The R5F100FCDFP#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 under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time.
Does the R5F100FCDFP#50 support in-system programming and secure firmware updates?
Yes, the R5F100FCDFP#50 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features. These enable secure firmware updates and prevent unauthorized modification of protected code flash regions during field deployment.
How many analog input channels does the R5F100FCDFP#50 provide, and what ADC resolution is supported?
The R5F100FCDFP#50 provides 12 analog input channels with a 10-bit successive approximation ADC. It supports internal 1.45 V reference voltage and an integrated temperature sensor, and operates across the full 1.6–5.5 V supply range without external reference components.
What low-power modes are available on the R5F100FCDFP#50, and what is the lowest achievable current draw?
The R5F100FCDFP#50 supports HALT, STOP, and SNOOZE modes. In HALT mode with only RTC and LVD active, it draws just 0.57 μA - the lowest current state - enabling multi-year battery operation in always-on sensor applications.
Is the R5F100FCDFP#50 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100FCDFP#50 shares identical pinout and electrical characteristics with all other 44-pin LQFP RL78/G13 devices (e.g., R5F100FCAFP#50, R5F101FCDFP#50), enabling direct substitution within the same footprint when flash configuration and data flash requirements align.
