Product details
Overview
R5F101FJDFP#V0 from Renesas is a 44-pin LQFP, 5.5-V, 32-MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, featuring ultra-low power consumption (66 μA/MHz), real-time clock, 10-bit ADC (26 channels), and UART/SPI/I²C interfaces - deployed in industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F101FJDFP#V0 datasheet, R5F101FJDFP#V0 pinout, R5F101FJDFP#V0 application, or R5F101FJDFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and integrated low-voltage detector with 14-level programmable reset threshold.
Technical Context
The R5F101FJDFP#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 RTC mode). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and a watchdog timer driven by dedicated low-speed oscillator.
Its peripheral set includes up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8-channel 16-bit timers, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, and 2–8-channel CSI (SPI-compatible serial interface), all operating across 1.6–5.5 V supply range.
Key Specifications

FAQ
Does R5F101FJDFP#V0 include on-chip data flash memory?
No, R5F101FJDFP#V0 does not include on-chip data flash memory. Per RL78/G13 family documentation, the "101" prefix denotes variants without data flash (unlike "100" series which include 4–8 KB). Code flash remains fully functional for program storage and self-programming, but persistent parameter storage requires external EEPROM or FRAM.
What is the maximum ADC resolution and channel count supported by R5F101FJDFP#V0?
R5F101FJDFP#V0 supports an 8/10-bit resolution successive approximation ADC with up to 26 analog input channels. The device uses VDD as reference by default but can configure P20/P21 as AVREFP/AVREFM for ratiometric measurements. Internal 1.45 V reference and temperature sensor are available when HS mode is selected.
Is R5F101FJDFP#V0 pin-compatible with other RL78/G13 44-pin LQFP variants?
Yes, R5F101FJDFP#V0 shares identical 44-pin LQFP (10 × 10 mm, 0.8-mm pitch) mechanical and electrical pinout with all RL78/G13 44-pin LQFP devices, including R5F100FJDFP#V0 and R5F104GJDFP#V0. Signal mapping, power/ground pin locations, and debug interface pins are consistent across the family for drop-in replacement within same package variant.
What industrial temperature grade does R5F101FJDFP#V0 support?
R5F101FJDFP#V0 supports the industrial temperature grade of -40°C to +85°C, indicated by the "D" suffix in its ordering code structure. This qualification meets requirements for factory automation, building controls, and outdoor equipment where ambient thermal stress exceeds commercial-grade limits.
How does the low-voltage detector (LVD) function in R5F101FJDFP#V0?
The on-chip LVD in R5F101FJDFP#V0 offers 14 selectable voltage thresholds ranging from 1.6 V to 4.2 V in 0.2 V steps. It can generate either interrupt requests or automatic system reset, providing flexible brown-out protection. Configuration is performed via dedicated system control registers, and detection operates independently of CPU clock state - ensuring reliability during power transitions.
