Product details
Overview
R5F100FEAFP#10 from Renesas is a 44-pin LQFP-44, 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates UART, I²C, SPI, 10-bit ADC (16 channels), RTC, and watchdog timer for embedded control in industrial sensors and smart meters.
For engineers reviewing the R5F100FEAFP#10 datasheet, R5F100FEAFP#10 pinout, R5F100FEAFP#10 application, or R5F100FEAFP#10 equivalent, key selection criteria include its 44-pin LQFP package, -40°C to +85°C industrial temperature grade (D), integrated data flash with background rewriting, and support for low-voltage operation down to 1.6 V.
Technical Context
The R5F100FEAFP#10 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It features dual clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and subsystem clock for RTC/LVD.
Its memory subsystem includes 64 KB code flash (1 KB block size, security lock), 4 KB data flash (1M rewrite cycles, BGO support), and 4 KB SRAM. Peripheral integration includes 2 UART channels (LIN-capable), up to 10 I²C/SimpI²C channels, and an 8/10-bit ADC with internal 1.45 V reference and temperature sensor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FEAFP#30 | Identical electrical specs and pinout; differs only in packaging (embossed tape vs. tray) | No functional difference; selected for automated SMT line compatibility | Choose #30 for high-volume pick-and-place assembly; #10 for manual prototyping or low-volume production |
| R5F101FEAFP#10 | Omits 4 KB data flash; retains same code flash, RAM, peripherals, and package | Suitable where EEPROM emulation is unnecessary; lower cost for fixed-parameter systems | Select when nonvolatile parameter storage is handled externally or not required; verify firmware compatibility with missing data flash API |
