Product details
Overview
R5F101PGAFB#V0 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, industrial-grade RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, 32 MHz max CPU speed, and true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors, smart meters, and embedded control systems requiring robust timing, analog sensing, and serial connectivity.
For engineers reviewing the R5F101PGAFB#V0 datasheet, R5F101PGAFB#V0 pinout, R5F101PGAFB#V0 application, or R5F101PGAFB#V0 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature rating (D-grade), integrated 10-bit 26-channel ADC, real-time clock with calendar, and dual UART/LIN support for fieldbus interfacing.
Technical Context
The R5F101PGAFB#V0 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline and configurable instruction cycle time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It integrates a 12-bit interval timer, 16-bit timer array (12 channels), and real-time clock with alarm and correction functions.
Its peripheral set includes up to 10 I²C/Simplified I²C channels, 4 UART/LIN interfaces, 8 CSI/SPI channels, and a 10-bit A/D converter with internal 1.45 V reference and temperature sensor-enabling mixed-signal control without external signal conditioning in compact industrial nodes.

FAQ
What is the flash memory configuration of the R5F101PGAFB#V0?
The R5F101PGAFB#V0 contains 96 KB of on-chip code flash memory and no dedicated data flash memory. This aligns with the R5F101x series designation, where data storage must be implemented in code flash sectors or external non-volatile memory. The flash supports self-programming with boot swap functionality for safe firmware updates.
Does the R5F101PGAFB#V0 support LIN bus communication?
Yes, the R5F101PGAFB#V0 supports LIN bus communication through its UART peripheral, which includes LIN-specific features such as break detection, sync byte handling, and checksum calculation. This eliminates the need for external LIN transceivers in basic node implementations, reducing system cost and complexity.
What is the operating temperature range for the R5F101PGAFB#V0?
The R5F101PGAFB#V0 is rated for industrial operation from -40°C to +85°C (D-grade). This qualification ensures reliable performance in factory automation, smart metering, and building control environments where ambient temperatures exceed consumer-grade limits.
How many analog input channels does the R5F101PGAFB#V0 support?
The R5F101PGAFB#V0 supports up to 26 analog input channels via its 10-bit successive-approximation ADC. Inputs include dedicated ANI0–ANI25 pins and can be configured with internal 1.45 V reference or external AVREFP/AVREFM for ratiometric or absolute measurements.
What package type and pin count does the R5F101PGAFB#V0 use?
The R5F101PGAFB#V0 uses a 100-pin LFQFP package with 0.5 mm pitch and 14 mm × 14 mm body size. The "FB" suffix in the part number explicitly denotes this LFQFP-0.5mm variant, and the "#V0" indicates tray packaging for automated assembly.
Can the R5F101PGAFB#V0 operate from a single 1.8 V supply?
Yes, the R5F101PGAFB#V0 operates across a wide supply range of 1.6 V to 5.5 V, making it compatible with 1.8 V logic systems. At 1.8 V, the maximum CPU frequency is reduced per datasheet specifications, but all peripherals-including ADC, timers, and serial interfaces-remain fully functional within their voltage-rated ranges.
