Overview
R5F100LGAFA#30 from Renesas is a 64-pin LQFP-0.65mm, 128 KB flash, 8 KB data flash, 12 KB RAM RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), real-time clock, 10-bit ADC (26 channels), and integrated UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LGAFA#30 datasheet, R5F100LGAFA#30 pinout, R5F100LGAFA#30 application, or R5F100LGAFA#30 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), on-chip data flash rewrite endurance (1,000,000 cycles), RTC calendar function, and support for background data flash programming during code execution.
Technical Context
The R5F100LGAFA#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 low-power mode). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar/alarm/correction, 1× watchdog timer, 2–4-channel DMA, and serial interfaces (CSI/SPI, UART/LIN, I²C) - all configurable via SFRs without external timing components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGAFB#30 | Same core, memory, and peripherals but in 64-pin LFQFP (0.5-mm pitch); no RTC calibration function | Used where finer-pitch assembly is available and RTC precision correction is not required | Select when footprint compatibility with 0.5-mm pitch PCB processes is prioritized over RTC calibration capability |
| R5F101LGAFA#30 | Identical package and pinout but lacks data flash (0 KB); retains full code flash and peripheral set | Targeted at cost-optimized designs where non-volatile parameter storage is handled externally | Choose when application does not require embedded data logging or field-updatable configuration storage |

Does the R5F100LGAFA#30 include a real-time clock with calendar functionality?
Yes, the R5F100LGAFA#30 integrates a full-featured real-time clock (RTC) with calendar support for 99 years, alarm generation, and automatic clock correction. This RTC operates independently in HALT mode with only 0.57 μA current draw, allowing accurate timekeeping during ultra-low-power states - critical for timestamped data logging in industrial and metering applications.
How much data flash memory does the R5F100LGAFA#30 have, and what is its endurance?
The R5F100LGAFA#30 includes 8 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 simultaneously rewriting data flash - essential for robust firmware updates and persistent parameter storage in field-deployed R5F100LGAFA#30 systems.
What is the industrial temperature range supported by the R5F100LGAFA#30?
The R5F100LGAFA#30 is rated for operation from -40°C to +105°C, meeting industrial-grade requirements (G-suffix). This extended range is validated across all specified peripherals, including the 10-bit ADC, RTC, and serial interfaces - ensuring reliable performance in harsh environments such as factory automation, outdoor metering, and enclosed appliance control units.
Can the R5F100LGAFA#30 operate from a single 1.8 V supply?
Yes, the R5F100LGAFA#30 supports single-supply operation from 1.6 V to 5.5 V. At 1.8 V, it maintains full functionality including 32 MHz operation (with reduced current), 10-bit ADC conversion, RTC operation, and data flash programming - making it suitable for energy-harvesting and low-voltage battery systems where supply regulation headroom is constrained.
