Product details
Overview
R5F100FGAFP#50 from Renesas Electronics is a 44-pin LQFP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (24 channels), RTC calendar, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100FGAFP#50 datasheet, R5F100FGAFP#50 pinout, R5F100FGAFP#50 application, or R5F100FGAFP#50 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), on-chip debug support, self-programmable flash with boot swap, background data flash rewriting, and 44-pin LQFP-0.8 mm pitch package compatibility with standard reflow profiles.
Technical Context
The R5F100FGAFP#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar and alarm, and watchdog timer driven by dedicated low-speed oscillator.
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - all configurable via register-based control without external glue logic. DMA controller supports 4-channel transfers with 2-clock latency between SFR and internal RAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FGAFP#30 | Identical silicon; differs only in packaging (tray vs. embossed tape). | No functional difference; used in manual assembly or low-volume prototyping. | Select #30 for engineering samples or small-batch builds requiring tray delivery. |
| R5F101FGAFP#50 | Omits 8 KB data flash; retains same 96 KB code flash, 8 KB RAM, peripherals, and package. | Not suitable for applications requiring nonvolatile parameter storage or firmware update staging. | Choose when data flash is unnecessary and cost reduction is prioritized over field-upgrade capability. |
Compared with R5F100FGAFP#50, the #30 variant offers identical functionality in tray packaging for lab use, while R5F101FGAFP#50 removes data flash to lower unit cost - making it viable only where background rewriting and secure parameter storage are not required.

Does the R5F100FGAFP#50 support in-system programming and secure firmware updates?
Yes, the R5F100FGAFP#50 supports full in-system programming via on-chip debug interface and includes boot swap functionality, flash shield window, and block erase prohibition - allowing secure field firmware updates without external programmers and preventing unauthorized code modification during deployment.
What analog capabilities does the R5F100FGAFP#50 provide for sensor interfacing?
The R5F100FGAFP#50 integrates a 10-bit successive-approximation ADC with up to 24 input channels, selectable internal 1.45 V reference voltage, and an on-chip temperature sensor calibrated across –40°C to +105°C. These features enable direct ratiometric sensing and thermal compensation without external references or discrete sensors.
How does the R5F100FGAFP#50 manage ultra-low-power operation in battery-powered applications?
The R5F100FGAFP#50 achieves ultra-low-power operation through multiple hardware-supported modes: STOP mode draws just 0.57 μA while retaining RTC and LVD functionality, HALT mode consumes 66 μA/MHz, and SNOOZE mode allows selective peripheral wake-up - collectively enabling multi-year battery life in wireless sensor and metering applications.
Is the R5F100FGAFP#50 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 44-pin LQFP-0.8 mm pitch package (e.g., R5F100FAAFP#50, R5F100FHAFP#50) share identical pinouts and electrical characteristics - enabling drop-in replacement across memory configurations (16–512 KB flash) and feature sets (data flash presence/absence) without PCB redesign.
