Product details
Overview
R5F100LGGFA#X0 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit MCU with 512 KB flash, 8 KB data flash, 32 KB RAM, and operation from -40°C to +105°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock for embedded control in harsh environments.
For engineers reviewing the R5F100LGGFA#X0 datasheet, R5F100LGGFA#X0 pinout, R5F100LGGFA#X0 application, or R5F100LGGFA#X0 equivalent, key selection criteria include its extended temperature rating, on-chip debug support, self-programmable flash with boot swap, background data flash rewriting, and integrated low-voltage detector with 14-level interrupt/reset options.
Technical Context
The R5F100LGGFA#X0 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). Its memory subsystem includes 512 KB code flash (1 KB blocks), 8 KB data flash with 1M rewrite cycles, and 32 KB SRAM - all accessible under single 1.6–5.5 V supply.
Peripherals are tightly coupled to power management: DMA controller (4 channels), 16-bit timer array (16 channels), real-time clock with calendar/alarm, watchdog timer, and analog features including internal 1.45 V reference and temperature sensor. All operate within the industrial -40°C to +105°C ambient range without derating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGAFA#V0 | Same 64-pin LQFP package, 512 KB flash, but consumer-grade (-40°C to +85°C); no G-grade temp qualification | Suitable for indoor, climate-controlled equipment where extended temperature is not required | Select when cost sensitivity outweighs industrial environmental robustness |
| R5F101LGGFA#X0 | Identical package and peripherals, but lacks data flash (0 KB); retains 512 KB code flash and same CPU performance | Applicable where firmware-only storage suffices and EEPROM-like data retention is handled externally | Choose when data logging is implemented via external serial EEPROM or FRAM |
Compared with R5F100LGGFA#X0, R5F100LGAFA#V0 trades industrial temperature margin for lower unit cost, while R5F101LGGFA#X0 removes data flash to reduce die size - both retain identical pinout and core functionality but require design validation for thermal or nonvolatile storage requirements.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LGGFA#X0?
The R5F100LGGFA#X0 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 41 DMIPS (Dhrystone MIPS) at that frequency. This performance is sustained across its full industrial temperature range (-40°C to +105°C) without derating, enabling deterministic real-time control in demanding applications.
Does the R5F100LGGFA#X0 support in-system programming and secure firmware updates?
Yes, the R5F100LGGFA#X0 supports full in-system programming via its on-chip debug interface and includes dedicated flash security features: block erase prohibition, boot swap functionality, and flash shield window control. These capabilities enable field firmware updates and protect intellectual property without requiring external programming hardware.
How many analog input channels does the R5F100LGGFA#X0 ADC support, and what is its resolution?
The R5F100LGGFA#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports internal 1.45 V reference voltage and includes an on-chip temperature sensor - both usable across the full -40°C to +105°C operating range without external components.
What power-saving modes are available on the R5F100LGGFA#X0, and what is the lowest current consumption achievable?
The R5F100LGGFA#X0 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across -40°C to +105°C. This enables multi-year battery operation in always-on monitoring systems such as smart utility meters or remote sensors.
Is the R5F100LGGFA#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 (e.g., R5F100LxxAFA#X0, R5F101LxxAFA#X0) share identical pinouts and electrical characteristics. This allows direct substitution between variants differing only in memory size or data flash presence - provided software and configuration match the selected part's feature set.
