Product details
Overview
R5F101FHAFP#50 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6 V to 5.5 V across -40°C to +85°C industrial temperature range. It integrates 16-bit timer (12 channels), 10-bit ADC (12 channels), UART/LIN (2 channels), I²C (3 channels), and ultra-low-power STOP mode (0.57 μA) for battery-powered sensor nodes and smart metering interfaces.
For engineers reviewing the R5F101FHAFP#50 datasheet, R5F101FHAFP#50 pinout, R5F101FHAFP#50 application, or R5F101FHAFP#50 equivalent, key selection criteria include its data flash retention (1M rewrite cycles), real-time clock with calendar/alarm, on-chip high-accuracy oscillator (±1.0% @ 32 MHz), and support for background data flash programming during code execution.
Technical Context
The R5F101FHAFP#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory map includes 1 MB address space, with dedicated SFR regions for peripheral control and DMA transfer between 8/16-bit registers and internal RAM in just 2 clocks per transfer.
Power management includes HALT, STOP, and SNOOZE modes, with on-chip POR and 14-level LVD for reset/interrupt generation. The device supports self-programming of code flash and background operation (BGO) for data flash writes while executing from program memory - critical for firmware-over-the-air updates in field-deployed devices.

This eliminates external crystal requirements for UART/LIN timing-critical applications while ensuring reliable communication at 115.2 kbps or LIN 19.2 kbps baud rates without calibration.
Does the R5F101FHAFP#50 support background data flash programming?
Yes, the R5F101FHAFP#50 supports background operation (BGO) for data flash writes - allowing the CPU to execute instructions from program memory while rewriting data flash. This capability is essential for R5F101FHAFP#50-based systems that require uninterrupted operation during firmware parameter updates or event logging.
What is the data flash endurance and voltage range for rewriting on the R5F101FHAFP#50?
The R5F101FHAFP#50 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with rewrite voltage support from VDD = 1.8 V to 5.5 V. This ensures reliable non-volatile storage across wide input voltage ranges - critical for R5F101FHAFP#50 deployments in battery-backed or unregulated power environments.
How many analog input channels and what ADC resolution does the R5F101FHAFP#50 offer?
The R5F101FHAFP#50 integrates a 10-bit successive approximation register (SAR) ADC with 12 selectable analog input channels and an internal 1.45 V reference voltage. This configuration enables precise measurement of voltage, current, and temperature signals in R5F101FHAFP#50-based sensor interfaces without external reference components.
What low-power modes are available on the R5F101FHAFP#50, and what is the lowest current draw?
The R5F101FHAFP#50 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.57 μA (typical) - making it suitable for R5F101FHAFP#50 applications requiring multi-year battery life, such as wireless sensor transmitters and utility meter backup systems.
