Product details
Overview
R5F101PGDFB#V0 from Renesas is a 48-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, no data flash, and industrial-grade -40°C to +85°C operation. It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit 26-channel ADC, real-time clock with calendar, and ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD). Used in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101PGDFB#V0 datasheet, R5F101PGDFB#V0 pinout, R5F101PGDFB#V0 application, or R5F101PGDFB#V0 equivalent, key selection criteria include its 48-pin LFQFP package, absence of data flash memory, industrial temperature rating, and support for LIN-bus UART, I²C, and CSI serial interfaces in resource-constrained embedded control designs.
Technical Context
The R5F101PGDFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.03125 μs @32 MHz to 30.5 μs @32.768 kHz). It supports background data flash operations via BGO-though this part lacks data flash-and includes a dedicated low-speed on-chip oscillator for watchdog timer operation independent of main clock domain.
Power management includes on-chip POR and LVD with 14 selectable voltage thresholds, DMA controller (4 channels), and hardware multiplier/divider/MAC supporting 16×16→32-bit and 32÷32→32-bit operations. Serial interface flexibility is provided by up to 10 I²C/Simplified I²C channels, 4 UART/LIN channels, and 8 CSI channels-all configurable per pin function mapping.

FAQ
What is the flash and RAM capacity of the R5F101PGDFB#V0?
The R5F101PGDFB#V0 integrates 96 KB of code flash memory and 8 KB of on-chip RAM. It does not include data flash memory - unlike the R5F100x series - making it ideal for applications where firmware-only storage is sufficient and external EEPROM or FRAM is acceptable for parameter retention. This configuration reduces die size and cost while maintaining full RL78/G13 peripheral compatibility.
Does the R5F101PGDFB#V0 support LIN bus communication?
Yes, the R5F101PGDFB#V0 supports LIN bus communication through its UART peripherals, which include LIN-mode functionality compliant with LIN specification 2.2A. The UART can generate break fields, sync bytes, and identifier handling required for LIN slave node operation - enabling direct connection to automotive body electronics networks without external transceivers in many implementations.
What is the operating temperature range for the R5F101PGDFB#V0?
The R5F101PGDFB#V0 is rated for industrial operation from –40°C to +85°C, indicated by the 'D' suffix in its family designation. This makes it suitable for deployment in factory automation equipment, outdoor metering enclosures, and commercial HVAC systems where ambient conditions exceed consumer-grade limits but do not require extended 105°C operation.
Can the R5F101PGDFB#V0 operate without an external crystal?
Yes, the R5F101PGDFB#V0 features a high-accuracy on-chip oscillator calibrated to ±1.0% across 1.8–5.5 V and –20 to +85°C, enabling full operation - including UART at 19.2 kbps and RTC timekeeping - without any external crystal or resonator. This reduces BOM cost and PCB area while maintaining timing integrity for most industrial and metering applications.
How many ADC channels does the R5F101PGDFB#V0 support?
The R5F101PGDFB#V0 supports up to 26 analog input channels with its 10-bit successive-approximation ADC. Inputs include dedicated AVREFP/AVREFM pins for precise ratiometric measurements, internal temperature sensor, and 1.45 V reference voltage source - allowing simultaneous monitoring of multiple sensors such as thermistors, pressure transducers, and current shunts in compact embedded systems.
