Product details
Overview
R5F100LFGFA#30 from Renesas is a 64-pin LQFP-0.65mm, 512 KB flash, 8 KB data flash, 32 KB RAM RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in industrial control panels requiring deterministic real-time response and extended battery life.
For engineers reviewing the R5F100LFGFA#30 datasheet, R5F100LFGFA#30 pinout, R5F100LFGFA#30 application, or R5F100LFGFA#30 equivalent, key selection considerations include its integrated RTC with calendar/alarm, 26-channel 10-bit ADC, 16-channel 16-bit timer suite, LIN-capable UARTs, and hardware BCD correction for metering interfaces.
Technical Context
The R5F100LFGFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual power domains enabling independent operation of RTC and LVD during STOP mode.
Its peripheral set includes up to 16× 16-bit timers with interval/real-time/watchdog functions, 3× I²C/Simplified I²C channels, 2× CSI (SPI-compatible) interfaces, and 2–4-channel DMA supporting 2-clock transfers between SFR and RAM - all optimized for deterministic low-latency sensor and actuator control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGFA#30 | Same 64-pin LQFP package, but 384 KB flash / 8 KB data flash / 24 KB RAM - lower memory footprint | Suitable for cost-sensitive industrial HMIs where full 512 KB flash is unused | Select when firmware size remains below 384 KB and BOM cost optimization is prioritized |
| R5F101LGFA#30 | Identical package and pinout, but no data flash (0 KB); retains 512 KB code flash and 32 KB RAM | Applicable where non-volatile parameter storage is handled externally or via external EEPROM | Choose when data logging is offloaded to external memory and flash endurance requirements are relaxed |
Compared with R5F100LFGFA#30, R5F100LGFA#30 trades flash capacity for lower unit cost without altering peripheral count or power profile, while R5F101LGFA#30 removes data flash to simplify qualification and reduce test overhead - both retain identical real-time performance and industrial temperature grading.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LFGFA#30?
The R5F100LFGFA#30 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0 %), achieving 41 DMIPS performance. This metric reflects its RL78 CPU core's 3-stage pipeline efficiency and is measured under standard conditions per Renesas R01DS0131EJ0380 Rev.3.80 specification.
Does the R5F100LFGFA#30 support hardware-based LIN bus communication?
Yes, the R5F100LFGFA#30 includes UART peripherals with built-in LIN protocol support (ISO 17987), enabling direct connection to LIN transceivers without software bit-banging. This capability is confirmed in the "Serial interface" section of the R01DS0131EJ0380 datasheet and applies to all RL78/G13 variants with UART channels.
What is the data flash endurance and voltage range for reprogramming the R5F100LFGFA#30?
The R5F100LFGFA#30 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with reprogramming supported across the full supply range of VDD = 1.8 V to 5.5 V. Background operation allows code execution during data flash writes, preserving real-time responsiveness.
How does the R5F100LFGFA#30 achieve ultra-low-power STOP mode operation?
The R5F100LFGFA#30 achieves 0.57 μA STOP mode by powering down the CPU, flash, and most peripherals while retaining RTC operation, LVD monitoring, and SRAM contents. This state is entered via software command and exited by external interrupt or RTC alarm - verified in Section 1.1 "Ultra-low power consumption technology" of R01DS0131EJ0380.
What package type and pin count does the R5F100LFGFA#30 use?
The R5F100LFGFA#30 uses a 64-pin LQFP package with 0.65-mm pitch (12 × 12 mm body), identified by the "FA" suffix in the part number and confirmed in Table 1-1 of R01DS0131EJ0380 Rev.3.80. The "#30" denotes tray packaging for automated assembly.
