Product details
Overview
R5F101FKAFP#30 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, and 20 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101FKAFP#30 datasheet, R5F101FKAFP#30 pinout, R5F101FKAFP#30 application, or R5F101FKAFP#30 equivalent, key selection criteria include its 44-pin LQFP-0.8mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for background data flash rewriting via BGO.
Technical Context
The R5F101FKAFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based RTC with alarm/correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3–10× I²C/Simplified I²C channels, 2–4× UART/LIN interfaces, 2–8× CSI (SPI-compatible) channels, and DMA controller with 2/4 channels enabling 2-clock transfers between SFR and RAM - all optimized for deterministic real-time control in resource-constrained embedded systems.

FAQ
What is the operating temperature range for the R5F101FKAFP#30?
The R5F101FKAFP#30 is rated for industrial operation from –40°C to +85°C (suffix 'D'), making it suitable for deployment in factory automation equipment, outdoor metering, and HVAC control units where ambient thermal stress exceeds consumer-grade limits. This rating is confirmed in the RL78/G13 datasheet Rev.3.80, Section 1.1.
Does the R5F101FKAFP#30 include on-chip data flash memory?
No, the R5F101FKAFP#30 does not include on-chip data flash memory. As indicated by the '101' in its part number per Figure 1-1 of the RL78/G13 datasheet, this variant omits data flash to reduce cost and power consumption - unlike the '100' series (e.g., R5F100FKAFP#30) which provides 8 KB. Firmware must use code flash or external storage for nonvolatile parameters.
Which package type and pin count does the R5F101FKAFP#30 use?
The R5F101FKAFP#30 uses a 44-pin plastic LQFP package (10 × 10 mm, 0.8-mm pitch), identified by the 'FP' suffix and '#30' tray packaging code. This matches the mechanical outline PLQP0044GC-A in Renesas' ordering guide and is compatible with standard 0.8-mm pitch LQFP footprints used in industrial PCB designs.
Can the R5F101FKAFP#30 operate from a single 3.3 V supply?
Yes, the R5F101FKAFP#30 operates over a wide supply range of 1.6 V to 5.5 V, fully supporting standard 3.3 V logic rails. Its I/O ports tolerate mixed-voltage signaling (1.8 V/2.5 V/3 V), and internal regulators maintain core stability - enabling direct integration with 3.3 V sensors, RF modules, and level-shifter-free communication interfaces.
What debugging and programming interfaces are supported by the R5F101FKAFP#30?
The R5F101FKAFP#30 supports on-chip debug via the single-wire debug interface (SWD) using the TOOLRxD pin (P11), eliminating need for dedicated JTAG headers. It also enables self-programming of code flash with boot swap and flash shield window functions - allowing secure, field-upgradable firmware without external programmers.
