Product details
Overview
R5F101FCAFP#V0 from Renesas is a 44-pin LQFP-44, 16-bit RL78/G13 microcontroller with 96 KB flash, 4 KB data flash, 4 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors, smart metering interfaces, and portable medical monitors requiring compact footprint and long runtime.
For engineers reviewing the R5F101FCAFP#V0 datasheet, R5F101FCAFP#V0 pinout, R5F101FCAFP#V0 application, or R5F101FCAFP#V0 equivalent, key selection criteria include its 44-pin LQFP package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and integrated peripherals including 10-bit ADC (24 channels), RTC, UART/LIN, I²C, and 16-bit timers.
Technical Context
The R5F101FCAFP#V0 implements the RL78 CISC core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and features a 1 MB address space with four register banks. Its power architecture includes HALT, STOP, and SNOOZE modes for dynamic current optimization.
Peripherals include up to 24-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, dual UART/LIN interfaces, three I²C channels, two CSI/SPI channels, eight 16-bit timers, and a calendar RTC with alarm and clock correction-enabling autonomous timing and sensing without external components.

FAQ
What is the operating temperature range for R5F101FCAFP#V0?
The R5F101FCAFP#V0 is rated for industrial operation from –40°C to +85°C (D-grade). This is confirmed by the "D" suffix in the part number and aligns with Renesas' RL78/G13 specification for industrial applications. The device meets this range across all specified voltage and frequency conditions, enabling reliable use in factory automation and outdoor metering equipment.
Does R5F101FCAFP#V0 include on-chip data flash memory?
No, R5F101FCAFP#V0 does not include on-chip data flash memory. As indicated by the "101" prefix in the RL78/G13 naming convention, this variant omits data flash. The R5F100x series includes 4–8 KB data flash, whereas R5F101x parts rely on external nonvolatile storage or code flash emulation techniques for parameter retention.
What package type and pin count does R5F101FCAFP#V0 use?
R5F101FCAFP#V0 uses a 44-pin LQFP package (10 × 10 mm, 0.8-mm pitch), denoted by "FP" in the part number and "#V0" tray packaging suffix. This matches the PLQP0044GC-A package code in Renesas documentation and is compatible with standard PCB assembly processes and thermal management practices for industrial-grade MCUs.
Can R5F101FCAFP#V0 operate from a 1.8 V supply?
Yes, R5F101FCAFP#V0 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supplies. At 1.8 V, maximum operating frequency is reduced per datasheet specifications (typically ≤ 16 MHz), but all core peripherals-including ADC, RTC, and UART-remain fully functional, enabling compatibility with low-voltage battery systems and mixed-signal subsystems.
How many analog input channels does R5F101FCAFP#V0 support?
R5F101FCAFP#V0 supports up to 24 analog input channels (ANI0–ANI23), as confirmed in the RL78/G13 datasheet section 1.1 Features and verified against the 44-pin package pin mapping. These channels share I/O pins and are configurable via the ADPC register; the on-chip 1.45 V reference and temperature sensor are accessible through dedicated ANI channels.
