Product details
Overview
R5F101FKDFP#30 from Renesas is a 44-pin LQFP-44, 32-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, and 8 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 (24 channels), RTC calendar, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101FKDFP#30 datasheet, R5F101FKDFP#30 pinout, R5F101FKDFP#30 application, or R5F101FKDFP#30 equivalent, key selection criteria include its 44-pin LQFP package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and compatibility with Renesas' RL78 toolchain and E2 emulator for low-power firmware development.
Technical Context
The R5F101FKDFP#30 implements the RL78 CPU core with 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock), and a 1 MB address space. It integrates a 12-bit interval timer, real-time clock with calendar/alarm/correction, and watchdog timer driven by dedicated low-speed oscillator.
Its peripheral set includes up to 24-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, and 2–8 CSI (SPI-compatible) channels - all configurable via register-based control without external glue logic.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101FKDFP#30?
The R5F101FKDFP#30 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator calibrated to ±1.0% accuracy across 1.8–5.5 V and –40°C to +85°C. The R5F101FKDFP#30 sustains this performance without external crystal dependency, simplifying clock tree design.
Does the R5F101FKDFP#30 include on-chip data flash memory?
No, the R5F101FKDFP#30 does not include on-chip data flash memory. As indicated by the "101" family designation in the Renesas part numbering scheme, this variant provides only 96 KB of code flash and 8 KB of RAM. For designs requiring nonvolatile parameter storage, R5F100FKDFP#30 (with 4 KB data flash) is the functionally matched alternative in the same 44-pin LQFP package.
What are the supported low-power modes and their typical current consumption for the R5F101FKDFP#30?
The R5F101FKDFP#30 supports HALT (66 μA/MHz), STOP (0.57 μA with RTC and LVD active), and SNOOZE modes. In STOP mode, the device maintains RTC calendar, alarm, and voltage monitoring functions while drawing less than 1 μA - validated per R01DS0131EJ0380 Rev.3.80, Page 1. This enables decade-scale battery operation in remote sensing applications using the R5F101FKDFP#30.
Which communication interfaces are available on the R5F101FKDFP#30, and how many instances does it support?
The R5F101FKDFP#30 integrates UART/LIN (2 channels), I²C/Simplified I²C (3 channels), and CSI (2 channels). All interfaces are multiplexed onto GPIO pins and configurable via peripheral enable registers. UART0 supports full LIN 2.2 features including auto-synchronization and checksum generation - critical for automotive body electronics and industrial control networks using the R5F101FKDFP#30.
What is the ADC resolution, channel count, and reference voltage options for the R5F101FKDFP#30?
The R5F101FKDFP#30 features a 10-bit successive-approximation ADC with up to 24 input channels. It supports external reference (AVREFP/AVREFM pins) or internal 1.45 V reference. The integrated temperature sensor is accessible via dedicated ANI channel and calibrated in production - enabling accurate thermal compensation in motor control or power supply monitoring using the R5F101FKDFP#30.
