Product details
Overview
R5F101FGDFP#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 (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101FGDFP#V0 datasheet, R5F101FGDFP#V0 pinout, R5F101FGDFP#V0 application, or R5F101FGDFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8mm-pitch package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and compatibility with Renesas' RL78 toolchain and E2 emulator for low-power firmware development.
Technical Context
The R5F101FGDFP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz) and 1 MB address space. It integrates a high-accuracy ±1.0% on-chip oscillator (32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC operation.
Power management includes on-chip POR and 14-level voltage detector (LVD) with interrupt/reset options; peripheral set comprises 2–4 channel DMA, 16-bit timer (12 channels), 12-bit interval timer, real-time clock with calendar/alarm, and 10-bit ADC with internal 1.45 V reference and temperature sensor - all optimized for deterministic real-time control in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FGDFP#V0 | Same 44-pin LQFP package, identical pinout, but includes 8 KB data flash and 12 KB RAM | Required where background data logging (e.g., black-box event capture) or frequent parameter updates are needed | Select when non-volatile parameter storage beyond code flash is mandatory; adds 4 KB RAM overhead |
| R5F101GDFP#V0 | 48-pin LQFP variant with identical memory (96 KB/0 KB/8 KB), +4 GPIO, +2 ADC channels, +1 UART | Suitable for designs needing expanded I/O or additional serial interfaces without changing core firmware logic | Choose for future-proofing I/O headroom; requires PCB redesign due to 48-pin footprint |
Compared with R5F101FGDFP#V0, R5F100FGDFP#V0 adds data flash for robust parameter retention but increases cost and power in STOP mode; R5F101GDFP#V0 trades pin count for interface scalability - neither is pin-compatible, but both share the same RL78/G13 instruction set and toolchain.

FAQ
Does R5F101FGDFP#V0 include on-chip data flash memory?
No, R5F101FGDFP#V0 does not include data flash memory. The "101" in the part number explicitly denotes zero data flash (per Renesas' RL78/G13 naming convention), unlike "100" variants which integrate 4–8 KB. Code flash self-programming remains supported via boot swap functionality in R5F101FGDFP#V0.
What is the maximum operating frequency and corresponding performance of R5F101FGDFP#V0?
R5F101FGDFP#V0 operates at up to 32 MHz using the high-speed on-chip oscillator, delivering 41 DMIPS (Dhrystone MIPS). Its minimum instruction execution time is 0.03125 μs at 32 MHz, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation.
Which package type and pin count does R5F101FGDFP#V0 use?
R5F101FGDFP#V0 uses a 44-pin LQFP package (10 × 10 mm, 0.8 mm pitch), indicated by the "FP" suffix and "#V0" tray packaging code. This matches the PLQP0044GC-A package code in Renesas' official ordering matrix and is compatible with standard 0.8 mm pitch LQFP footprints.
What temperature grade is specified for R5F101FGDFP#V0?
R5F101FGDFP#V0 is rated for industrial operation from -40°C to +85°C, denoted by the "D" in the part number (R5F101FGDFP#V0 → "D" = Industrial grade). It is not qualified for the extended -40°C to +105°C (G grade) or consumer-grade -40°C to +85°C (A grade with different screening).
Can R5F101FGDFP#V0 operate without an external crystal?
Yes, R5F101FGDFP#V0 can operate without an external crystal. Its high-accuracy on-chip oscillator supports frequencies from 1 MHz to 32 MHz with ±1.0% tolerance across 1.8–5.5 V and -20°C to +85°C - sufficient for UART communication, RTC, and most timing-critical embedded functions.
