Product details
Overview
R5F100LGGFB#X0 from Renesas is a 64-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 512 KB flash, 8 KB data flash, 32 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes just 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F100LGGFB#X0 datasheet, R5F100LGGFB#X0 pinout, R5F100LGGFB#X0 application, or R5F100LGGFB#X0 equivalent, key selection criteria include its 512 KB code flash with self-programming, 32 KB RAM for real-time control stacks, 64-pin LFQFP-0.5mm pitch package, -40°C to +105°C industrial temperature rating, and integrated low-power peripherals enabling sub-1μA sleep modes in energy-constrained designs.
Technical Context
The R5F100LGGFB#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 ultra-low-speed mode). Its memory subsystem includes 512 KB on-chip flash with 1 KB block erase, 8 KB data flash with background operation (BGO), and 32 KB RAM - all accessible under single 1.6–5.5 V supply.
Peripherals are tightly coupled to power management: DMA supports 4-channel transfers with 2-clock latency between SFR and RAM; the 10-bit ADC offers 26 input channels with internal 1.45 V reference and temperature sensor; and the real-time clock provides calendar support (99 years), alarm, and clock correction - all operable in STOP/HALT modes with dedicated low-speed oscillator.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGGBG#U0 | Same core, memory, and peripherals but in 64-pin VFBGA (4 × 4 mm, 0.4 mm pitch); no LFQFP footprint compatibility. | Targeted at space-constrained PCBs where QFN/BGA layout is preferred over exposed-pad QFP; requires different reflow profile and test access strategy. | Select when board area is critical and assembly capability supports fine-pitch BGA; avoid if manual rework or thermal pad inspection is required. |
| R5F101LGGBG#U0 | Omits 8 KB data flash; retains 512 KB code flash, 32 KB RAM, and identical peripheral set - lower cost for fixed-parameter firmware. | Suitable for applications where configuration data is stored externally or parameters are factory-programmed only; eliminates BGO complexity. | Choose when data logging or field-updatable calibration is unnecessary; reduces bill-of-materials cost by removing redundant flash resources. |
Compared with R5F100LGGFB#X0, the VFBGA variant enables higher-density layouts but sacrifices serviceability, while the R5F101LGGBG#U0 reduces nonvolatile data storage capability - making the R5F100LGGFB#X0 optimal for field-upgradable, thermally demanding, and maintenance-accessible industrial designs.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LGGFB#X0?
The R5F100LGGFB#X0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The device maintains this performance across its full 1.6–5.5 V supply range and industrial temperature grade (-40°C to +105°C), making it suitable for real-time control tasks in motor drives and protocol stacks. The R5F100LGGFB#X0 also supports dynamic clock switching to reduce power during low-activity phases.
Does the R5F100LGGFB#X0 support in-system programming and secure firmware updates?
Yes, the R5F100LGGFB#X0 includes on-chip debug functionality and full self-programming capability for both code and data flash. It supports boot swap, flash shield window, and block-erase prohibition - enabling secure over-the-air or field firmware updates without external programming hardware. These features are implemented in silicon and documented in the Flash Self-Programming Library (R20UT2944), ensuring reliable and tamper-resistant updates in deployed R5F100LGGFB#X0 systems.
How many analog input channels does the R5F100LGGFB#X0 ADC support, and what reference options are available?
The R5F100LGGFB#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference inputs (AVREFP/AVREFM) and an internal 1.45 V reference voltage - selectable via register configuration. The internal reference is factory-trimmed and usable across the full operating temperature range, eliminating the need for external reference ICs in precision measurement applications. This ADC capability is fully functional in the R5F100LGGFB#X0's 64-pin LFQFP package.
What low-power modes are available on the R5F100LGGFB#X0, and what is the lowest achievable current draw?
The R5F100LGGFB#X0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.57 μA - verified per datasheet R01DS0131EJ0380. This ultra-low quiescent current enables multi-year operation on coin-cell batteries. Wake-up sources include external interrupts, RTC alarms, and LVD events, all configurable without exiting low-power state. The R5F100LGGFB#X0 achieves this while maintaining full SRAM retention and register context.
Is the R5F100LGGFB#X0 pin-compatible with other RL78/G13 devices in the same package?
Yes, the R5F100LGGFB#X0 is pin-compatible with all other 64-pin LFQFP variants in the RL78/G13 family - including R5F100LC–LLAFB and R5F101LC–LLAFB series - sharing identical pinout, power sequencing, and I/O electrical characteristics. This allows direct substitution for memory or feature scaling (e.g., downgrading to 128 KB flash or upgrading to data-flash-less variants) without PCB redesign. The R5F100LGGFB#X0's pin mapping is defined in Section 1.3.6 of the official datasheet.
