Product details
Overview
R5F100FEAFP#50 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V. It integrates a 10-bit ADC (24 channels), RTC, 16-bit timers (12 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F100FEAFP#50 datasheet, R5F100FEAFP#50 pinout, R5F100FEAFP#50 application, or R5F100FEAFP#50 equivalent, key selection criteria include its 44-pin LQFP package, 64 KB code flash with self-programming, 10-bit ADC resolution across 24 analog inputs, real-time clock with calendar/alarm, and support for LIN-bus via UART - all validated for industrial ambient operation up to +85°C.
Technical Context
The R5F100FEAFP#50 implements the RL78 CPU core with a 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). Its memory subsystem includes 64 KB on-chip flash (1 KB block size), 4 KB data flash with background operation (BGO), and 4 KB RAM - enabling firmware updates and data logging without halting program execution.
Peripheral integration includes dual DMA channels (2-clock transfer latency between SFR and RAM), hardware multiplier/divider, 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, and configurable I/O ports (up to 39 pins with N-ch open-drain, TTL input, and pull-up options) supporting mixed-voltage interfacing (1.8/2.5/3.0 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FFAFP#50 | 96 KB flash, 8 KB data flash, 8 KB RAM - identical package and peripheral set. | Higher firmware complexity (e.g., OTA update stack + encryption) requires larger code/data space. | Select when future firmware expansion or dual-bank secure boot is required; pinout and layout remain unchanged. |
| R5F101FEAFP#50 | No data flash (0 KB); otherwise identical flash/RAM/peripherals/timing/power specs. | Applications needing only code storage (no field data logging or parameter retention) benefit from lower cost and simplified qualification. | Choose where EEPROM emulation or external nonvolatile storage suffices; avoids data flash wear management overhead. |
Compared with R5F100FEAFP#50, R5F100FFAFP#50 offers scalable firmware headroom without altering board design, while R5F101FEAFP#50 reduces BOM cost and qualification scope by removing data flash - making it optimal for fixed-function, high-volume controllers.

FAQ
What is the maximum operating frequency and oscillator accuracy of the R5F100FEAFP#50?
The R5F100FEAFP#50 operates at up to 32 MHz using its high-speed on-chip oscillator, which maintains ±1.0 % accuracy across VDD = 1.8–5.5 V and TA = –20°C to +85°C. This eliminates external crystal requirements in many applications while ensuring timing predictability for UART, LIN, and PWM generation - critical for reliable R5F100FEAFP#50 system operation.
Does the R5F100FEAFP#50 support LIN bus communication, and how is it implemented?
Yes, the R5F100FEAFP#50 supports LIN 2.2 protocol through its UART peripheral, which includes built-in LIN break detection and sync field generation. No external transceiver is needed for basic node functionality - the R5F100FEAFP#50 directly drives the LIN bus via a simple discrete level-shifter, reducing BOM count and board area in automotive body control modules.
How much data flash does the R5F100FEAFP#50 include, and what are its endurance specifications?
The R5F100FEAFP#50 integrates 4 KB of on-chip data flash rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing program execution from main flash while rewriting data flash - a key capability for firmware-over-the-air (FOTA) parameter storage and event logging in the R5F100FEAFP#50.
What low-power modes are available on the R5F100FEAFP#50, and what is the lowest achievable current draw?
The R5F100FEAFP#50 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - enabling decade-scale battery life in metering and remote sensing. The R5F100FEAFP#50 achieves this via selective peripheral gating and deep-sleep clock domain isolation, verified across its full industrial temperature range.
Is the R5F100FEAFP#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., R5F100FAAFP#50, R5F100FFAFP#50, R5F101FEAFP#50) share identical pinouts and electrical characteristics. This allows hardware reuse across firmware variants; for example, upgrading from R5F100FEAFP#50 to R5F100FFAFP#50 requires only a flash reprogramming step, not a PCB change.
