Product details
Overview
R5F100LGDFA#30 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 operation down to 0.57 μA in RTC+LVD mode. It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock for industrial control and sensor node applications.
For engineers reviewing the R5F100LGDFA#30 datasheet, R5F100LGDFA#30 pinout, R5F100LGDFA#30 application, or R5F100LGDFA#30 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), integrated data flash with 1M rewrite cycles, background operation capability, 64-pin LQFP package with 0.65-mm pitch, and support for low-voltage operation from 1.6 V.
Technical Context
The R5F100LGDFA#30 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It supports multiple low-power modes-HALT, STOP, and SNOOZE-with dedicated on-chip oscillators and voltage detector (LVD) interrupt/reset across 14 levels.
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, calendar-based RTC with alarm and correction, watchdog timer, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM. The 10-bit A/D converter operates across the full 1.6–5.5 V supply range and includes internal reference voltage (1.45 V) and temperature sensor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGDFB#30 | Same core, memory, and peripherals-but in 64-pin LFQFP (0.5-mm pitch) package | Requires PCB redesign due to finer pitch and different land pattern; suited for higher-density layouts | Select when board space constraints favor 0.5-mm pitch and compatibility with existing LFQFP footprint libraries |
| R5F101LGDFB#30 | Omits data flash (0 KB); retains same code flash, RAM, peripherals, and package | Not suitable for applications requiring nonvolatile parameter storage or field firmware updates | Choose where cost reduction is prioritized over data logging or secure firmware update capability |
Compared with R5F100LGDFA#30, R5F100LGDFB#30 offers identical functionality in a denser package but demands tighter layout tolerances, while R5F101LGDFB#30 removes data flash entirely-reducing cost and code security features but maintaining real-time control capability.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LGDFA#30?
The R5F100LGDFA#30 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over –40°C to +85°C), delivering 41 DMIPS. Its RL78 core achieves a minimum instruction execution time of 0.03125 μs in high-speed mode, enabling deterministic real-time response for motor control and sensor fusion tasks. The R5F100LGDFA#30 maintains this performance across its full 1.6–5.5 V supply range.
Does the R5F100LGDFA#30 support in-system programming and secure firmware updates?
Yes, the R5F100LGDFA#30 supports full in-system programming via its on-chip debug interface and includes flash security features such as block erase prohibition and flash shield window function. It also implements boot swap functionality for fail-safe firmware updates-ensuring the R5F100LGDFA#30 remains operational even if an update is interrupted or corrupted.
How many analog input channels does the R5F100LGDFA#30 support, and what is its ADC resolution?
The R5F100LGDFA#30 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It operates across the full 1.6–5.5 V supply range and includes an internal 1.45 V reference voltage and integrated temperature sensor-both accessible via dedicated pins (P20/ANI0/AVREFP and P21/ANI1/AVREFM). The R5F100LGDFA#30 supports simultaneous sampling and flexible trigger sources including timers and external events.
What low-power modes are available on the R5F100LGDFA#30, and what is the lowest achievable current draw?
The R5F100LGDFA#30 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA (typical) at 3.0 V and 25°C. Its ultra-low-power design enables battery-operated applications to achieve multi-year operation-especially when combined with the R5F100LGDFA#30's ability to wake from STOP via peripheral interrupts like UART reception or ADC completion.
Is the R5F100LGDFA#30 qualified for industrial temperature operation, and what is its specified range?
Yes, the R5F100LGDFA#30 carries the 'G' suffix denoting industrial temperature qualification, with a guaranteed operating ambient temperature range of –40°C to +105°C. This rating applies across all specified electrical parameters-including flash endurance, ADC accuracy, oscillator stability, and I/O drive strength-making the R5F100LGDFA#30 suitable for demanding environments such as factory automation, power supplies, and outdoor metering equipment.
