Product details
Overview
R5F100LFAFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode). It targets battery-powered industrial sensors, smart meters, and embedded control systems requiring long runtime and robust timing.
For engineers reviewing the R5F100LFAFB#30 datasheet, R5F100LFAFB#30 pinout, R5F100LFAFB#30 application, or R5F100LFAFB#30 equivalent, key selection considerations include its integrated real-time clock with calendar/alarm, 26-channel 10-bit ADC, 16-channel 16-bit timer suite, LIN-capable UARTs, and support for background data flash rewriting - all within a -40°C to +105°C operating range.
Technical Context
The R5F100LFAFB#30 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI/SPI channels, DMA controller (4 channels), 16× general-purpose I/O ports with N-ch open-drain capability, and hardware multiplier/divider/accumulator - all optimized for deterministic real-time control in resource-constrained environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LFAFB#30 | No data flash memory (0 KB); identical package, pinout, and peripheral set otherwise. | Suitable where parameter storage is handled externally or via external EEPROM; lower cost where flash retention isn't required. | Select when firmware-only storage suffices and BGO-based field updates are unnecessary. |
| RL78/G14 R5F104LEAFA#30 | Higher flash (512 KB), larger RAM (32 KB), same 64-pin LQFP-0.65mm package; adds USB 2.0 and more timers. | Better suited for complex HMI or USB-connected devices; not drop-in due to different pin mapping and voltage requirements (VDD=1.8–5.5 V vs. R5F100LFAFB#30's 1.6–5.5 V). | Choose for future-proofing or when USB host/device capability and expanded memory are needed - requires PCB redesign. |
Compared with R5F100LFAFB#30, R5F101LFAFB#30 removes data flash but retains identical power/performance specs for simpler firmware-only use cases, while RL78/G14 R5F104LEAFA#30 offers significantly higher memory and USB connectivity at the cost of non-pin-compatible layout changes and tighter supply constraints.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LFAFB#30?
The R5F100LFAFB#30 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports dynamic clock scaling - from high-speed 32 MHz operation (0.03125 μs instruction time) down to ultra-low-speed 32.768 kHz (30.5 μs instruction time) - enabling precise trade-offs between throughput and power in the R5F100LFAFB#30.
Does the R5F100LFAFB#30 support in-system programming and secure firmware updates?
Yes, the R5F100LFAFB#30 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features for security. It enables self-programming of both code and data flash memory - including background operation (BGO) for data flash writes - allowing safe, field-upgradable firmware and parameter storage in the R5F100LFAFB#30 without halting application execution.
What analog peripherals are integrated into the R5F100LFAFB#30?
The R5F100LFAFB#30 integrates a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. It also supports differential analog measurements using AVREFP/AVREFM pins. These capabilities eliminate external ADCs and references in many sensor interface designs, directly supporting precision analog acquisition in the R5F100LFAFB#30.
How does the R5F100LFAFB#30 handle low-power operation in battery-powered applications?
The R5F100LFAFB#30 achieves industry-leading low-power operation with 66 μA/MHz active current and just 0.57 μA in HALT mode with RTC and LVD active. Its multiple low-power modes - HALT, STOP, and SNOOZE - allow rapid wake-up (< 4 μs) and intelligent peripheral triggering. This makes the R5F100LFAFB#30 ideal for battery-powered industrial sensors and smart meters requiring multi-year operation on primary cells.
Is the R5F100LFAFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LFAFB#30 is fully pin-compatible with all other 64-pin LFQFP RL78/G13 variants sharing the FB suffix (e.g., R5F100LGAFB#30, R5F100LHAFB#30), including identical pin functions, electrical characteristics, and package dimensions. This enables seamless migration across memory/configurations without PCB redesign - a key advantage of the R5F100LFAFB#30 within its family.
