Overview
R5F100FGDFP#V0 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (24 channels), and real-time clock with calendar support - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100FGDFP#V0 datasheet, R5F100FGDFP#V0 pinout, R5F100FGDFP#V0 application, or R5F100FGDFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8mm-pitch package, industrial-grade -40°C to +85°C operation (D-grade), on-chip debug interface, and support for LIN-bus UART and background data flash rewriting.
Technical Context
The R5F100FGDFP#V0 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 subsystem clock). It integrates dual power domains enabling independent RTC/LVD operation during deep sleep.
Its peripheral set includes 4-channel DMA, 16-bit timer array (12 channels), 3× I²C/Simplified I²C interfaces, 2× UART/LIN channels, and 2× CSI (SPI-compatible) serial interfaces - all configurable via dedicated system control registers and supported by hardware-accelerated multiply/divide/MAC units.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FGAFP#V0 | Same 96 KB flash, 8 KB data flash, 8 KB RAM, but in 44-pin LQFP with 0.65-mm pitch (PLQP0044GC-D); lacks LVD level 14 support. | Targeted at cost-sensitive consumer designs where tighter pitch and reduced LVD granularity are acceptable. | Select when board layout uses 0.65-mm pitch footprints and full 14-level LVD is not required. |
| R5F101FGDFP#V0 | Identical package and pinout, but no data flash (0 KB); retains same code flash, RAM, peripherals, and power specs. | Suitable for applications requiring only code storage and no field-updatable parameter storage or event logging. | Choose when data retention requirements are met by external EEPROM or when flash endurance is not critical. |
Compared with R5F100FGDFP#V0, R5F100FGAFP#V0 offers smaller footprint compatibility at the cost of LVD flexibility, while R5F101FGDFP#V0 removes data flash to reduce cost and simplify qualification - both retain identical real-time performance and industrial temperature rating.

Does the R5F100FGDFP#V0 support in-system programming and secure firmware updates?
Yes, the R5F100FGDFP#V0 supports self-programming with boot swap and flash shield window functions. Its 96 KB code flash includes block-erase prohibition and write-protection features, enabling secure over-the-air updates and preventing unauthorized firmware modification - confirmed in Section 1.1 Features of the RL78/G13 datasheet.
What analog capabilities does the R5F100FGDFP#V0 provide for sensor interfacing?
The R5F100FGDFP#V0 integrates a 10-bit ADC with 24 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. It supports differential measurements via AVREFP/AVREFM pins and operates across the full 1.6–5.5 V supply range - making it suitable for direct connection to resistive, capacitive, and thermistor-based sensors without external signal conditioning.
How does the R5F100FGDFP#V0 achieve ultra-low power consumption in battery-operated systems?
The R5F100FGDFP#V0 achieves ultra-low power via multiple hardware-optimized modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE. Its STOP mode retains RTC calendar and voltage monitoring while disabling CPU and most peripherals - validated for multi-year operation on CR2032 batteries in industrial sensor deployments.
Is the R5F100FGDFP#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100FGDFP#V0 shares identical 44-pin LQFP-0.8mm-pitch pinout with all RL78/G13 members in the PLQP0044GC-A package (e.g., R5F100EGDFP#V0, R5F100HGDFP#V0), including consistent power, reset, debug, and peripheral pin assignments - enabling scalable memory upgrades without PCB redesign.
