Product details
Overview
R5F100LGDFB#V0 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces requiring robust timing, analog sensing, and LIN/UART communication.
For engineers reviewing the R5F100LGDFB#V0 datasheet, R5F100LGDFB#V0 pinout, R5F100LGDFB#V0 application, or R5F100LGDFB#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, integrated 10-bit 26-channel ADC with temperature sensor, real-time clock with calendar/alarm, and support for SNOOZE mode wake-up via serial interface or GPIO-critical for ultra-low-duty-cycle embedded control.
Technical Context
The R5F100LGDFB#V0 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). It integrates dual-clock domains: high-speed main system clock (up to 32 MHz) and independent low-speed on-chip oscillator for watchdog and RTC.
Its peripheral set includes 8× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar and clock correction, 3× I²C/Simplified I²C channels, 2× UART/LIN channels, 2× CSI (SPI-compatible) channels, and DMA controller with 4 channels-enabling concurrent background data flash rewriting (BGO) while executing code from program memory.

IC Role / Device Role / Timing Role: Real-time scheduler coordinating 100 ms sensor reads, 1 s actuator updates, and 10 s network comms using interval timer and UART. Use Value: 4-channel DMA offloads UART/ADC transfers from CPU-ensures deterministic timing under 80% CPU load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LGDFB#V0 | No data flash memory (0 KB); identical core, peripherals, and package. | Not suitable for applications requiring non-volatile parameter storage or field firmware updates. | Select when only code storage is needed and cost reduction is critical; requires external EEPROM/NVRAM for configuration data. |
| RL78/G14 R5F104LEAFB#V0 | Enhanced RL78/G14 core; adds 32 KB RAM, 256 KB flash, USB 2.0 FS, and enhanced ADC (12-bit, 32 ch). | Targets USB-connected devices and higher-resolution sensing; consumes more power in active mode (72 μA/MHz). | Choose for future-proofing with USB connectivity or when >12 KB RAM is required for complex protocols or larger buffers. |
Compared with R5F100LGDFB#V0, R5F101LGDFB#V0 eliminates data flash to reduce cost and die size but sacrifices field-updatable parameter storage, while R5F104LEAFB#V0 trades lower power efficiency for USB capability and expanded memory-making R5F100LGDFB#V0 optimal for cost-sensitive, battery-operated industrial controllers needing reliable nonvolatile data logging.

FAQ
What is the maximum operating temperature range for the R5F100LGDFB#V0?
The R5F100LGDFB#V0 is rated for industrial operation from −40°C to +105°C, as indicated by the 'G' suffix in its part number per Renesas' RL78/G13 ordering guide. This makes it suitable for deployment in harsh environments such as motor control enclosures, outdoor metering units, and factory automation equipment where ambient temperatures exceed standard commercial limits.
Does the R5F100LGDFB#V0 support in-circuit debugging without external hardware?
Yes, the R5F100LGDFB#V0 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. It supports full-speed debugging, breakpoint setting, and memory inspection via the dedicated SWJ-DP interface using only four pins (VDD, VSS, RESET, and TCK)-no external debug probe is required beyond standard JTAG/SWD cabling.
How many serial communication interfaces does the R5F100LGDFB#V0 integrate?
The R5F100LGDFB#V0 integrates three types of serial interfaces: up to 2 CSI (SPI-compatible) channels, up to 4 UART/LIN channels (with LIN bus support enabled on UART0/UART1), and up to 10 I²C/Simplified I²C channels. For this specific variant (64-pin LFQFP), it supports 2 CSI, 2 UART/LIN, and 3 I²C channels-sufficient for multi-sensor data aggregation and host communication.
Can the R5F100LGDFB#V0 operate from a single 1.8 V supply?
Yes, the R5F100LGDFB#V0 supports operation from 1.6 V to 5.5 V, including stable 1.8 V operation across its full temperature range. At 1.8 V, it achieves up to 16 MHz CPU frequency (per datasheet Section 17.1), enabling ultra-low-power designs such as coin-cell-powered remote sensors while maintaining compatibility with 1.8 V logic peripherals.
Is the R5F100LGDFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 MCUs in the 64-pin LFQFP-0.5mm package-including R5F100LGDFB#V0, R5F101LGDFB#V0, and R5F100LLAFB#V0-share identical pinouts and electrical characteristics. This allows drop-in replacement for memory or feature upgrades (e.g., swapping to higher flash or adding data flash) without PCB redesign.
