Product details
Overview
R5F101LGDFA#V0 from Renesas is a 64-pin LQFP-0.65mm, 128 KB flash, 8 KB RAM, RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), real-time clock, 10-bit ADC (26 channels), and integrated UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101LGDFA#V0 datasheet, R5F101LGDFA#V0 pinout, R5F101LGDFA#V0 application, or R5F101LGDFA#V0 equivalent, key selection criteria include its 128 KB code flash without data flash, -40°C to +85°C industrial temperature grade (D), LQFP-64 package, and support for SNOOZE mode with background data flash rewriting capability.
Technical Context
The R5F101LGDFA#V0 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 features an on-chip high-accuracy ±1.0% oscillator (1–32 MHz). It integrates a 12-bit interval timer, calendar-based RTC with alarm/correction, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2–4× UART/LIN channels, 2–8× CSI channels, and DMA controller with 2/4 channels - all operating within 1.6–5.5 V supply range and optimized for HALT/STOP/SNOOZE power modes.

FAQ
Does R5F101LGDFA#V0 include data flash memory?
No, R5F101LGDFA#V0 contains 128 KB of code flash memory but no dedicated data flash. This distinguishes it from the R5F100xxx series, which includes 4–8 KB of data flash. Applications requiring nonvolatile parameter storage must use external EEPROM or leverage code flash with wear-leveling firmware.
What is the maximum ADC resolution and channel count supported by R5F101LGDFA#V0?
The R5F101LGDFA#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It also provides internal 1.45 V reference voltage and an on-die temperature sensor - both accessible only in HS (high-speed main) mode per the RL78/G13 datasheet.
Is R5F101LGDFA#V0 pin-compatible with R5F100LGDFA#V0?
Yes, R5F101LGDFA#V0 and R5F100LGDFA#V0 share identical LQFP-64 pinout, electrical characteristics, and peripheral mapping. The only functional difference is the absence of data flash in the R5F101LGDFA#V0 variant - making them drop-in replacements where data flash is unused.
Which serial interfaces are available on R5F101LGDFA#V0 and how are they allocated?
R5F101LGDFA#V0 supports up to 3 I²C/Simplified I²C channels, 2–4 UART/LIN channels, and 2–8 CSI (SPI-like) channels. These share multiplexed pins - e.g., P10/P11 serve SCK00/SI00/RxD0/SDA00 - requiring careful peripheral assignment during hardware design and initialization.
What power modes does R5F101LGDFA#V0 support and what is the lowest current draw?
R5F101LGDFA#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.57 μA (typical) at VDD = 1.8–5.5 V and TA = –40 to +85°C - enabling multi-year battery life in infrequently awakened sensor applications.
