Product details
Overview
R5F100LFGFA#X0 from Renesas is a 64-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz operation (41 DMIPS), and ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock-targeted for battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F100LFGFA#X0 datasheet, R5F100LFGFA#X0 pinout, R5F100LFGFA#X0 application, or R5F100LFGFA#X0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature grade (G suffix), integrated data flash with 1M rewrite cycles, and support for SNOOZE mode for low-latency wake-up from deep sleep.
Technical Context
The R5F100LFGFA#X0 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 subsystem clock). It includes dual-voltage operation (1.6–5.5 V), on-chip power-on-reset and 14-level voltage detector, and background operation for data flash rewriting while executing code from program memory.
Its peripheral set includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 1× watchdog timer with dedicated low-speed oscillator, and flexible serial interfaces: 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible), and 3–10 I²C/Simplified I²C channels-all configurable via register-based control without external glue logic.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LFGFA#X0?
The R5F100LFGFA#X0 operates at up to 32 MHz with the high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. This dual-speed capability is fully supported in the R5F100LFGFA#X0 silicon revision per R01DS0131EJ0380.
Does the R5F100LFGFA#X0 include on-chip debug functionality?
Yes, the R5F100LFGFA#X0 includes full on-chip debug functionality compliant with Renesas E1/E20 emulators. It supports breakpoints, watchpoints, real-time trace, and flash programming via the single-wire debug interface (SWD) using pins P13 (TOOLCLK) and P11 (TOOLRxD). This capability is confirmed in Section 1.1 of the R01DS0131EJ0380 datasheet.
What are the data flash endurance and voltage requirements for the R5F100LFGFA#X0?
The R5F100LFGFA#X0 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. Background operation (BGO) allows code execution from main flash while rewriting data flash-enabling seamless firmware updates without halting system operation.
How does the R5F100LFGFA#X0 support low-power design in battery-operated systems?
The R5F100LFGFA#X0 supports multiple ultra-low-power modes: HALT (0.92 μA), STOP (0.57 μA with RTC + LVD), and SNOOZE (fast wake-up from STOP via serial receive). Its 66 μA/MHz active current, 1.6 V minimum supply, and on-chip voltage detector enable robust operation in coin-cell or energy-harvesting systems-verified in the electrical characteristics table of R01DS0131EJ0380.
Is the R5F100LFGFA#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 64-pin LQFP-0.65mm package-including R5F100LFGFA#X0, R5F100LCAFA#X0, and R5F100LLAFA#X0-share identical pinouts and mechanical footprints.
