Overview
R5F100FADFP#X0 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 modes (66 μA/MHz active, 0.57 μA RTC+LVD), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100FADFP#X0 datasheet, R5F100FADFP#X0 pinout, R5F100FADFP#X0 application, or R5F100FADFP#X0 equivalent, key selection criteria include its integrated RTC with calendar support, 10-bit 24-channel ADC, dual UART/LIN interfaces, and hardware multiplier for real-time motor control loop execution.
Technical Context
The R5F100FADFP#X0 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 integrates a 12-bit interval timer, real-time clock with alarm/calendar, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 16 channels of 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, and 2–8 CSI (SPI-compatible) channels - all configurable via on-chip SFRs without external glue logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FAAFP#V0 | Same 96 KB flash, 4 KB RAM, but uses 32 MHz high-speed on-chip oscillator only (no external crystal option); LQFP-44, tray packaging | Lacks RTC crystal pins and external clock input - unsuitable for calendar-aware applications requiring ±20 ppm accuracy | Select when cost-sensitive designs omit RTC functionality and accept internal oscillator drift (±1.0%) |
| R5F101FADFP#X0 | Identical pinout and package, but no data flash memory (0 KB); same 96 KB code flash and 4 KB RAM | Cannot perform background data logging or field-upgradable configuration storage - requires external EEPROM for persistent settings | Choose when firmware size constraints prevent use of data flash routines and external nonvolatile memory is already present |
Compared with R5F100FADFP#X0, R5F100FAAFP#V0 trades RTC precision for lower BOM cost, while R5F101FADFP#X0 removes data flash to reduce die size - both retain identical I/O count and peripheral sets but constrain specific embedded functionality.
