Overview
R5F101FJDFP#X0 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 1.6–5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 12-bit ADC (24 channels), and integrated UART/I²C/CSI interfaces for industrial control and sensor node applications.
For engineers reviewing the R5F101FJDFP#X0 datasheet, R5F101FJDFP#X0 pinout, R5F101FJDFP#X0 application, or R5F101FJDFP#X0 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 support for background data flash rewriting and real-time clock calendar functions.
Technical Context
The R5F101FJDFP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and includes dedicated hardware for DMA (4-channel), multiply-accumulate, and real-time clock with calendar/alarm functions.
It integrates peripheral subsystems including 16-bit timers (12 channels), 12-bit interval timer, watchdog timer with independent oscillator, and serial interfaces-2× UART/LIN, 3× I²C/Simplified I²C, and 2× CSI-configured via memory-mapped SFRs and supported by on-chip debug functionality.

FAQ
What is the flash memory configuration of the R5F101FJDFP#X0?
The R5F101FJDFP#X0 contains 96 KB of on-chip code flash memory and no data flash memory (R5F101x series designation confirms data flash omission). It includes 8 KB of RAM and supports self-programming of code flash with boot swap and flash shield window functions. The flash block size is 1 KB, and security features prohibit unauthorized block erase and rewriting.
Does the R5F101FJDFP#X0 support real-time clock functionality?
Yes, the R5F101FJDFP#X0 integrates a full-featured real-time clock (RTC) with calendar support for 99 years, alarm interrupt capability, and automatic clock correction. It operates independently in STOP mode with only 0.57 μA current draw when powered by VDD, and accepts external 32.768 kHz crystal or internal sub-system clock input.
What are the low-power operating modes supported by the R5F101FJDFP#X0?
The R5F101FJDFP#X0 supports HALT, STOP, and SNOOZE modes. In STOP mode with RTC and LVD active, it draws just 0.57 μA. Active-mode consumption is 66 μA/MHz at 32 MHz. These modes are controlled via system control registers and can be entered/exited using specific instruction sequences documented in the RL78/G13 User's Manual.
Which serial communication interfaces are available on the R5F101FJDFP#X0?
The R5F101FJDFP#X0 provides 2 UART/LIN channels, 3 I²C/Simplified I²C channels, and 2 CSI (Simplified SPI) channels. All interfaces are software-configurable via SFRs and support interrupt-driven or DMA-assisted operation. UART channels include LIN bus protocol support compliant with ISO 17987-4.
Is the R5F101FJDFP#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F101FJDFP#X0 shares identical 44-pin LQFP pinout with all other RL78/G13 devices in the PLQP0044GC-A package (e.g., R5F100FJDFP#X0, R5F101FJAFP#V0), including identical power, reset, clock, and peripheral pin assignments. This allows drop-in replacement where functional differences (e.g., data flash presence) are acceptable.
