Product details
Overview
R5F100FKDFP#30 from Renesas is a 44-pin LQFP-44, 32-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, and 20 KB RAM, operating at up to 32 MHz with 41 DMIPS performance and ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode). It integrates 16-bit timers, 10-bit ADC (24 channels), UART/LIN, I²C, CSI, RTC, and DMA for embedded control in industrial sensors and motor drives.
For engineers reviewing the R5F100FKDFP#30 datasheet, R5F100FKDFP#30 pinout, R5F100FKDFP#30 application, or R5F100FKDFP#30 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), integrated data flash with 1M rewrite cycles, background operation capability, and support for low-power STOP/HALT/SNOOZE modes in resource-constrained designs.
Technical Context
The R5F100FKDFP#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It supports dual-voltage I/O (1.8/2.5/3.0 V interface compatibility) and includes on-chip debug, self-programming with boot swap, and flash shield window security.
Its peripheral set includes 8–16 channels of 16-bit timer, 12-bit interval timer, calendar RTC with alarm/correction, watchdog timer with dedicated low-speed oscillator, and 3–10 channels of I²C/Simplified I²C - all configurable via register-level control without external components.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100FKDFP#30?
The R5F100FKDFP#30 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 μs in high-speed mode, with configurable clock sources including an internal ±1.0% accurate oscillator ranging from 1 MHz to 32 MHz. This enables deterministic real-time response in motor control and sensor fusion applications.
Does the R5F100FKDFP#30 support in-system programming and debugging without external tools?
Yes, the R5F100FKDFP#30 supports full in-circuit debugging and programming via its built-in TOOL interface using pins P11 (TOOLRxD) and P12 (TOOLTxD). This single-wire debug capability eliminates the need for dedicated JTAG/SWD headers, reducing PCB layout complexity and cost while maintaining full flash read/write/erase and breakpoint functionality during development and field updates.
How does the data flash memory in the R5F100FKDFP#30 differ from standard code flash in terms of usage and endurance?
The R5F100FKDFP#30 includes 8 KB of dedicated data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. Unlike code flash, it supports background operation (BGO): the CPU can execute instructions from program memory while simultaneously rewriting data flash. This enables reliable parameter storage, calibration data logging, and firmware update staging without halting real-time tasks.
What low-power modes are available on the R5F100FKDFP#30, and what peripherals remain active in each?
The R5F100FKDFP#30 offers HALT (0.23 μA), STOP (0.57 μA), and SNOOZE modes. In STOP mode, the RTC, LVD, and selected interrupts remain active-allowing time-based wake-up or fault-triggered recovery. SNOOZE mode keeps the ADC, UART, and CSI operational with reduced CPU clock, enabling low-latency sensor polling without full wake-up overhead. All modes retain RAM contents and register states.
Is the R5F100FKDFP#30 pin-compatible with other RL78/G13 variants in the same LQFP-44 package?
Yes, the R5F100FKDFP#30 is fully pin-compatible with all RL78/G13 devices in the 44-pin LQFP package (e.g., R5F100FAAFP#30, R5F100FLDFP#30), sharing identical pin functions, electrical characteristics, and mechanical dimensions. This enables hardware scalability-designers can migrate between 16 KB and 512 KB flash variants without PCB redesign, leveraging the same layout, decoupling, and signal integrity validation.
