Product details
Overview
R5F101FFAFP#30 from Renesas is a 44-pin LQFP-44, 32-bit RL78/G13 microcontroller with 96 KB flash, 4 KB RAM, and no data flash memory, operating at 32 MHz with 41 DMIPS performance and ultra-low-power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode) for industrial control, sensor nodes, and battery-powered HMI applications.
For engineers reviewing the R5F101FFAFP#30 datasheet, R5F101FFAFP#30 pinout, R5F101FFAFP#30 application, or R5F101FFAFP#30 equivalent, this page delivers verified specifications, package mapping, real-world use cases, and validated alternative options - all aligned to the RL78/G13 family's documented capabilities for industrial-grade embedded designs.
Technical Context
The R5F101FFAFP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and subsystem clock for RTC/LVD operation.
It integrates 8-channel 16-bit timers, 1-channel real-time clock with calendar/alarm, 10-bit 24-channel ADC with internal 1.45 V reference and temperature sensor, 3-channel I²C, 2-channel UART (LIN-capable), and 2-channel CSI (SPI-compatible) serial interfaces - all accessible within its 44-pin LQFP footprint.

FAQ
What is the flash memory configuration of the R5F101FFAFP#30?
The R5F101FFAFP#30 contains 96 KB of on-chip code flash memory and no data flash memory - consistent with the "101" series designation in the RL78/G13 family, which indicates data flash omission. This configuration reduces cost and simplifies firmware update architecture where persistent parameter storage is handled externally or not required.
Does the R5F101FFAFP#30 support LIN bus communication?
Yes, the R5F101FFAFP#30 supports LIN bus communication through its UART peripherals - specifically, UART0 and UART1 include LIN-mode functionality per the RL78/G13 datasheet. This enables direct integration into automotive body electronics or industrial sub-networks using standard LIN 2.x protocol stacks.
What package type and pin count does the R5F101FFAFP#30 use?
The R5F101FFAFP#30 uses a 44-pin LQFP package (10 × 10 mm, 0.8-mm pitch), designated by the "FP" suffix and "#30" tray packaging code. This surface-mount package provides mechanical robustness and thermal performance suitable for industrial reflow assembly and long-life deployments.
Can the R5F101FFAFP#30 operate from a single 1.8 V supply?
Yes, the R5F101FFAFP#30 operates across a 1.6 V to 5.5 V supply range, fully supporting 1.8 V nominal operation. At this voltage, it maintains full functionality including 32 MHz operation (with appropriate oscillator configuration), ADC conversion, and low-power modes - enabling compatibility with modern low-voltage logic families.
How many ADC channels does the R5F101FFAFP#30 provide, and what is their resolution?
The R5F101FFAFP#30 provides up to 24 analog input channels with 10-bit resolution. The ADC supports internal 1.45 V reference voltage and temperature sensor input, allowing accurate ratiometric measurements and system-level thermal monitoring without external components.
