Product details
Overview
R5F101PGAFA#V0 from Renesas is a 48-pin LQFP-0.65mm microcontroller in the RL78/G13 family, featuring a 16-bit CISC CPU core, 64 KB flash memory, 4 KB data flash, and 4 KB RAM. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode), targeting battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101PGAFA#V0 datasheet, R5F101PGAFA#V0 pinout, R5F101PGAFA#V0 application, or R5F101PGAFA#V0 equivalent, key selection criteria include its integrated 10-bit ADC (26 channels), real-time clock with calendar/alarm, LIN-capable UART, and support for background data flash rewriting - all within an industrial-grade -40°C to +85°C operating range.
Technical Context
The R5F101PGAFA#V0 implements the RL78 CPU core with a 3-stage pipeline, configurable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz), and 1 MB address space. It integrates a high-accuracy ±1.0% on-chip oscillator (selectable from 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC operation.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI/SPI channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all accessible via 39 general-purpose I/O pins with N-ch open-drain, TTL input, and pull-up options.

The R5F101PGAFA#V0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under these conditions, enabling responsive real-time control in applications such as motor commutation and sensor data preprocessing. The R5F101PGAFA#V0 also supports lower-frequency subsystem clocks down to 32.768 kHz for ultra-low-power RTC operation.
Does the R5F101PGAFA#V0 include data flash memory, and what are its endurance specifications?
Yes, the R5F101PGAFA#V0 integrates 4 KB of on-chip data flash memory, rated for 1,000,000 write/erase cycles (typical). It supports background operation (BGO), allowing program execution from code flash while data flash is being rewritten - essential for robust firmware updates and parameter storage in field-deployed R5F101PGAFA#V0 systems.
What analog features are available on the R5F101PGAFA#V0, and how many input channels does the ADC support?
The R5F101PGAFA#V0 includes an 8/10-bit successive-approximation ADC with up to 26 analog input channels. It features internal 1.45 V reference voltage and an integrated temperature sensor - both selectable only in high-speed main mode. These capabilities enable accurate voltage monitoring, thermistor-based temperature measurement, and sensor signal conditioning without external references or sensors in many R5F101PGAFA#V0 implementations.
Is the R5F101PGAFA#V0 qualified for industrial temperature operation, and what is its specified range?
Yes, the R5F101PGAFA#V0 is qualified for industrial applications with an operating ambient temperature range of -40°C to +85°C (D-grade). This specification is confirmed in the RL78/G13 datasheet and applies to all variants with the 'D' suffix in the part number family - including the R5F101PGAFA#V0 - making it suitable for deployment in factory automation, HVAC controls, and outdoor metering equipment.
How does the R5F101PGAFA#V0 support low-power operation, and what is its lowest active current consumption?
The R5F101PGAFA#V0 achieves ultra-low-power operation through multiple hardware modes: HALT, STOP, and SNOOZE. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it consumes just 0.57 μA - enabling multi-year battery life in always-on sensor applications. This value is measured at VDD = 1.8–5.5 V and TA = -20°C to +85°C, as specified in the R5F101PGAFA#V0 datasheet.
