Product details
Overview
R5F100PKDFB#V0 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, industrial-grade (−40°C to +85°C) RL78/G13 16-bit MCU with 256 KB flash, 8 KB data flash, 20 KB RAM, 32 MHz max CPU speed, and integrated RTC, 10-bit ADC (26 channels), UART, I²C, CSI, and low-power STOP/HALT/SNOOZE modes - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F100PKDFB#V0 datasheet, R5F100PKDFB#V0 pinout, R5F100PKDFB#V0 application, or R5F100PKDFB#V0 equivalent, key selection criteria include its 256 KB code flash with self-programming and boot swap, 8 KB background-operable data flash (1M rewrite cycles), 26-channel 10-bit ADC with internal temperature sensor, and ultra-low 0.57 μA RTC+LVD standby current - critical for energy-constrained embedded control.
Technical Context
The R5F100PKDFB#V0 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). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 2–4 channel DMA, 16×16→32-bit multiply-accumulate unit, and mixed-signal features including internal 1.45 V reference and temperature sensor - all operating across 1.6–5.5 V supply range.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100PKDFB#V0?
The R5F100PKDFB#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects integer instruction throughput under standard benchmark conditions and is achievable using the high-speed on-chip oscillator. The RL78 core's 3-stage pipeline and efficient CISC architecture enable consistent execution across its supported clock range (1–32 MHz).
Does the R5F100PKDFB#V0 support background operation for data flash writes?
Yes, the R5F100PKDFB#V0 supports Background Operation (BGO) for its 8 KB data flash. This allows the CPU to execute instructions from program memory while simultaneously erasing or rewriting data flash sectors - essential for logging sensor data or updating configuration parameters without interrupting real-time tasks.
What are the low-power modes available on the R5F100PKDFB#V0, and what is the lowest achievable current draw?
The R5F100PKDFB#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current draw at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables decade-scale operation on primary lithium batteries in metering and sensing applications.
How many analog input channels does the R5F100PKDFB#V0 support, and what ADC resolution is provided?
The R5F100PKDFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor - both accessible via dedicated ADC channels - enabling accurate sensor measurements without external components.
Is the R5F100PKDFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100PKDFB#V0 is pin-compatible with all other RL78/G13 devices in the 100-pin LFQFP (FB) package, including R5F100PLDFB#V0 and R5F101PKDFB#V0. Pin functions, power domains, and peripheral mappings are consistent across this package group, enabling hardware reuse and migration paths based on memory or feature requirements.
