Product details
Overview
R5F100LKAFA#30 from Renesas is a 64-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 384 KB flash, 8 KB data flash, 24 KB RAM, 16-bit RL78 CPU core, and real-time clock with calendar support. It operates from 1.6 V to 5.5 V, achieves 41 DMIPS at 32 MHz, and delivers ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), targeting battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F100LKAFA#30 datasheet, R5F100LKAFA#30 pinout, R5F100LKAFA#30 application, or R5F100LKAFA#30 equivalent, key selection criteria include its integrated RTC with calendar/alarm, background data flash rewriting (BGO), 10-bit 26-channel ADC with internal temperature sensor, and support for LIN-bus UART communication in compact LQFP-64 packaging.
Technical Context
The R5F100LKAFA#30 implements the RL78 CISC CPU core with 3-stage pipeline and configurable instruction timing (0.03125 μs min @ 32 MHz to 30.5 μs @ 32.768 kHz), enabling dynamic performance/power trade-offs. Its memory subsystem includes 384 KB code flash (1 KB block size, security-locked erase), 8 KB data flash with 1M-cycle endurance and BGO capability, and 24 KB SRAM - including dedicated RAM regions for flash library operations (start address FAF00H).
Peripherals are optimized for embedded control: dual DMA controller (4 channels), 16-bit timer array (16 channels), 12-bit interval timer, hardware multiplier/divider/MAC, and multi-protocol serial interfaces - including 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, and 2–8 CSI (SPI-compatible) channels - all operating across -40°C to +85°C ambient range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LKAFA#30 | No data flash (0 KB); same 384 KB code flash, 24 KB RAM, and peripheral set. | Not suitable where field-updatable calibration or logging data storage is required. | Select when firmware-only storage suffices and cost reduction is prioritized over data retention capability. |
| R5F100LKAFP#30 | Same memory and peripherals, but in 64-pin LQFP-0.80 mm pitch (FP package) instead of FA (0.65 mm). | Requires PCB layout revision due to larger pad pitch; incompatible with existing FA-footprint designs. | Choose only for new designs where 0.80 mm pitch simplifies assembly or matches legacy board standards. |
Compared with R5F100LKAFA#30, R5F101LKAFA#30 removes data flash to lower cost while retaining full code execution capability, whereas R5F100LKAFP#30 maintains identical functionality but mandates mechanical redesign due to different LQFP pitch - making R5F100LKAFA#30 the optimal choice for new compact industrial control designs requiring integrated data logging.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LKAFA#30?
The R5F100LKAFA#30 operates at up to 32 MHz and delivers 41 DMIPS performance. This is achieved using the high-speed on-chip oscillator (±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C), enabling deterministic real-time control in applications such as motor commutation and sensor fusion where cycle-count predictability matters.
Does the R5F100LKAFA#30 support background data flash rewriting (BGO), and what is the endurance specification?
Yes, the R5F100LKAFA#30 supports background data flash rewriting (BGO), allowing instruction execution from program memory while data flash is being updated. Its 8 KB data flash is rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V, making it suitable for frequent parameter logging or calibration storage in field-deployed equipment.
What are the key low-power modes supported by the R5F100LKAFA#30, and what is the current draw in STOP mode with RTC active?
The R5F100LKAFA#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across -40°C to +85°C - enabling decade-scale battery life in always-on monitoring applications like water/gas metering or environmental sensors.
How many analog input channels and what ADC resolution does the R5F100LKAFA#30 provide?
The R5F100LKAFA#30 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), including dedicated AVREFP/AVREFM pins and an internal temperature sensor. This eliminates external signal conditioning for basic thermal monitoring and multi-sensor analog aggregation.
Is the R5F100LKAFA#30 pin-compatible with other RL78/G13 variants in the same 64-pin LQFP-0.65mm package?
Yes, the R5F100LKAFA#30 shares identical pinout and package (64-pin LQFP, 0.65 mm pitch) with all other RL78/G13 devices ending in "LKAFA#30", including variants with different flash/RAM configurations (e.g., R5F100LCAFA#30). Pin compatibility enables scalable design reuse across performance tiers without PCB changes.
