Overview
R5F100LDGBG#W0 from Renesas is a 64-pin VFBGA-packaged 16-bit RL78/G13 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, supports ultra-low-power modes (0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, and real-time clock for embedded control in battery-powered and thermally demanding applications.
For engineers reviewing the R5F100LDGBG#W0 datasheet, R5F100LDGBG#W0 pinout, R5F100LDGBG#W0 application, or R5F100LDGBG#W0 equivalent, key selection criteria include its VFBGA-64 (4 × 4 mm, 0.4-mm pitch) footprint, G-grade temperature range (−40°C to +105°C), on-chip debug support, self-programming flash with boot swap, and background data flash rewriting capability.
Technical Context
The R5F100LDGBG#W0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction timing from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features dual power domains supporting independent voltage scaling for logic and analog peripherals.
Its integrated peripherals include a 12-bit interval timer, calendar-based real-time clock with alarm and correction, 16-channel 16-bit timer array, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM - all optimized for deterministic real-time response in motor control and sensor fusion systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGABG#W0 | Same VFBGA-64 package, G-grade, but 128 KB flash / 8 KB data flash / 12 KB RAM | Lower memory capacity suits simpler control tasks (e.g., basic HVAC controllers) without complex firmware or data logging | Select when full 512 KB flash is unnecessary and cost optimization is prioritized |
| R5F101LDGBG#W0 | Identical pinout and package, but no data flash (0 KB); same 512 KB code flash and 32 KB RAM | Eliminates background data rewriting - appropriate for fixed-parameter systems where runtime parameter storage is handled externally | Choose when EEPROM or external flash suffices for configuration storage and BGO is not required |
Compared with R5F100LDGBG#W0, R5F100LGABG#W0 reduces flash/RAM for cost-sensitive volume production, while R5F101LDGBG#W0 removes data flash to simplify qualification and reduce test overhead - both retain identical thermal, packaging, and peripheral compatibility for drop-in layout reuse.

What are the key low-power modes supported by the R5F100LDGBG#W0, and what is the lowest achievable current draw?
The R5F100LDGBG#W0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across the full −40°C to +105°C industrial temperature range. This ultra-low quiescent current enables decade-long battery life in metering and sensor applications, making the R5F100LDGBG#W0 ideal for energy-harvesting and maintenance-free deployments.
How many analog input channels does the R5F100LDGBG#W0 provide, and what ADC resolution and reference options are available?
The R5F100LDGBG#W0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports multiple reference sources: VDD, dedicated AVREFP/AVREFM pins, or an internal 1.45 V reference - the latter enabling stable measurements independent of supply variation. Temperature sensor readout is also supported, all confirmed in the R5F100LDGBG#W0 datasheet.
Is the R5F100LDGBG#W0 pin-compatible with other RL78/G13 variants in the same VFBGA-64 package?
Yes, the R5F100LDGBG#W0 shares identical pinout and electrical characteristics with all other RL78/G13 devices in the VFBGA-64 package (e.g., R5F100LCGBG#W0, R5F100LEGBG#W0), including power, ground, I/O, reset, clock, and debug signals. This allows hardware design reuse across memory/configurations - a verified feature of the R5F100LDGBG#W0 within the RL78/G13 family.
