Product details
Overview
R5F100LFAFB#10 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 512 KB flash, 8 KB data flash, 32 KB RAM, and operation from −40°C to +105°C. It delivers 41 DMIPS at 32 MHz, consumes just 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and targets battery-powered industrial sensors and smart actuators requiring low-power real-time control.
For engineers reviewing the R5F100LFAFB#10 datasheet, R5F100LFAFB#10 pinout, R5F100LFAFB#10 application, or R5F100LFAFB#10 equivalent, key selection criteria include its integrated RTC with calendar/alarm, 26-channel 10-bit ADC with internal 1.45 V reference, dual UART/LIN support, and hardware BGO for concurrent code execution during data flash rewriting - all within an AEC-Q100–compatible industrial temperature envelope.
Technical Context
The R5F100LFAFB#10 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 ultra-low-speed mode). Its memory subsystem includes 512 KB on-chip code flash (1 KB block size, security-protected erase/write), 8 KB data flash with background operation (BGO), and 32 KB RAM - enabling robust firmware updates and persistent parameter storage without halting application execution.
Peripheral integration includes up to 16 channels of 16-bit timer, 12-bit interval timer, real-time clock with calendar and clock correction, watchdog timer with dedicated low-speed oscillator, and flexible serial interfaces: 2–4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable for deterministic timing-critical industrial communication stacks.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LFAFB#10?
The R5F100LFAFB#10 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This enables real-time execution of control algorithms such as PID loops, sensor fusion, and protocol stacks (e.g., Modbus RTU or LIN) without external acceleration. Its 3-stage pipeline and CISC architecture optimize code density and deterministic timing - critical for industrial safety-critical functions.
Does the R5F100LFAFB#10 support hardware-based background operation for data flash writes?
Yes, the R5F100LFAFB#10 includes hardware background operation (BGO) for its 8 KB data flash. This allows the CPU to execute instructions from program memory while simultaneously rewriting data flash - essential for applications like energy meters or data loggers that must maintain uninterrupted operation during firmware updates or parameter saves.
What are the supported analog input capabilities of the R5F100LFAFB#10?
The R5F100LFAFB#10 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels and an internal 1.45 V reference voltage. It supports differential input modes and selectable sample-and-hold timing, enabling accurate multi-sensor monitoring (e.g., temperature, pressure, current) in industrial environments without external reference or signal conditioning components.
How does the R5F100LFAFB#10 achieve ultra-low power consumption in standby modes?
The R5F100LFAFB#10 achieves 0.57 μA in STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active - enabled by its proprietary low-leakage process and selective peripheral gating. The RTC maintains calendar time and can generate periodic wake-up interrupts, allowing battery-powered devices to operate for over a decade on a single coin cell.
Is the R5F100LFAFB#10 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LFAFB#10 is fully pin-compatible with all other 64-pin LFQFP RL78/G13 variants (e.g., R5F100LCAFB#10, R5F100LGAFB#10), sharing identical pin functions, electrical characteristics, and mechanical footprint. This enables design reuse and seamless migration across memory configurations without PCB revision.
