Product details
Overview
R5F100FEAFP#30 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 V to 5.5 V across -40°C to +85°C industrial temperature range. It integrates 16-bit timer (12 channels), 10-bit ADC (12 channels), UART/LIN, I²C, CSI, RTC, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in battery-powered and energy-sensitive applications.
For engineers reviewing the R5F100FEAFP#30 datasheet, R5F100FEAFP#30 pinout, R5F100FEAFP#30 application, or R5F100FEAFP#30 equivalent, key selection criteria include its 44-pin LQFP package, integrated LIN-capable UART, 12-channel 10-bit ADC, real-time clock with calendar function, and verified support for BGO data flash rewriting - all critical for motor control, sensor hubs, and industrial HMI designs requiring deterministic low-power operation.
Technical Context
The R5F100FEAFP#30 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). Its memory subsystem includes 64 KB on-chip code flash (1 KB block size), 4 KB data flash with background operation (BGO), and 4 KB RAM - enabling secure self-programming with boot swap and flash shield window functions.
Peripherals are tightly coupled to power management: DMA controller (4 channels), 16-bit timers (12 channels), 10-bit ADC (12 inputs, internal 1.45 V reference), and dual-clock domain operation (main + subsystem) allow concurrent RTC/calendar, LVD monitoring, and peripheral activity at sub-1 μA standby current. The device supports LIN bus via UART with automatic sync-break detection and checksum generation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FEAFP#50 | Identical silicon; differs only in packaging (embossed tape vs. tray). | No functional or electrical difference; suitable for automated SMT lines requiring tape-and-reel feed. | Select #50 for high-volume pick-and-place assembly; #30 preferred for prototyping and small-batch production. |
| R5F101FEAFP#30 | Omits 4 KB data flash; retains same 64 KB code flash, peripherals, and low-power features. | Not suitable for applications requiring nonvolatile parameter storage (e.g., calibration data, usage logs) without external EEPROM. | Choose R5F101FEAFP#30 only when data flash is unused and BOM cost reduction is prioritized over field-upgrade capability. |
Compared with R5F100FEAFP#50, the #30 variant offers immediate availability in tray packaging for evaluation and pilot builds, while R5F101FEAFP#30 trades data flash functionality for lower unit cost - making it viable only where firmware-only storage suffices and external nonvolatile memory is already present.

FAQ
What is the maximum operating frequency and clock source accuracy of the R5F100FEAFP#30?
The R5F100FEAFP#30 operates up to 32 MHz using its high-accuracy on-chip oscillator, specified at ±1.0% over VDD = 1.8–5.5 V and ambient temperature –20°C to +85°C. This eliminates need for external crystal in many applications while maintaining sufficient timing precision for UART/LIN communication and ADC sampling.
Does the R5F100FEAFP#30 support LIN bus communication natively?
Yes, the R5F100FEAFP#30 supports LIN 2.2 and SAE J2602 via its UART peripheral with hardware-assisted features: automatic sync-break detection, checksum generation (classic/enhanced), and configurable baud rate. No external LIN transceiver is required for basic node functionality, though one is needed for physical layer compliance.
How much data flash does the R5F100FEAFP#30 include, and what is its endurance?
The R5F100FEAFP#30 includes 4 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical). It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for field-updatable calibration tables or usage logs in the R5F100FEAFP#30.
What low-power modes are available on the R5F100FEAFP#30, and what is the lowest achievable current?
The R5F100FEAFP#30 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.57 μA (typical) at VDD = 3.0 V and TA = 25°C. This enables multi-year operation on coin cells in sensor nodes and smart thermostats using the R5F100FEAFP#30.
Is the R5F100FEAFP#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 44-pin LQFP package (e.g., R5F100FAAFP#30, R5F100FFAFP#30) share identical pinouts and electrical characteristics. Firmware and PCB layouts designed for R5F100FEAFP#30 can be reused across the family - enabling scalable memory upgrades (16–512 KB flash) without hardware redesign.
