Product details
Overview
R5F101LGAFA#V0 from Renesas is a 64-pin LQFP-0.65mm, 128 KB flash, 8 KB RAM, no data flash RL78/G13 16-bit microcontroller operating from 1.6–5.5 V, delivering 41 DMIPS at 32 MHz and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101LGAFA#V0 datasheet, R5F101LGAFA#V0 pinout, R5F101LGAFA#V0 application, or R5F101LGAFA#V0 equivalent, key selection criteria include its 64-pin LQFP package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D-grade), and integrated RTC, 10-bit ADC (26 channels), and multiple serial interfaces for embedded control.
Technical Context
The R5F101LGAFA#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 a 12-bit interval timer, real-time clock with calendar/alarm functions, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3–10× I²C/Simplified I²C channels, 2–4× UART/LIN, 2–8× CSI (SPI-compatible), 8–26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, and DMA controller with 2/4 channels supporting 2-clock transfers between SFR and RAM.

Does the R5F101LGAFA#V0 support real-time clock functionality with calendar features?
Yes, the R5F101LGAFA#V0 integrates a full-featured real-time clock with calendar support for 99 years, alarm generation, and clock correction. It operates independently in STOP mode using the 32.768 kHz crystal or internal oscillator, enabling time-stamped data logging and scheduled wake-up events without external components.
What is the operating temperature range specified for the R5F101LGAFA#V0?
The R5F101LGAFA#V0 is rated for industrial operation from -40°C to +85°C (D-grade), as indicated by the "D" suffix in its family classification. This rating is validated across all electrical specifications including flash programming, ADC accuracy, and peripheral timing - no derating required within this range.
How many analog input channels does the R5F101LGAFA#V0 support, and what is the ADC resolution?
The R5F101LGAFA#V0 supports up to 26 analog input channels with a 10-bit successive-approximation ADC. It includes an internal 1.45 V reference voltage and an integrated temperature sensor, both accessible via dedicated ANI pins - enabling precision sensor measurements without external references.
Is the R5F101LGAFA#V0 pin-compatible with any data-flash-equipped variants?
The R5F101LGAFA#V0 is pin-compatible and software-compatible with the R5F100LGAFA#V0, which shares identical package, pinout, clock tree, and peripheral register map - differing only in the presence of 8 KB data flash.
