Product details
Overview
R5F101LKDFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), 384 KB flash, 8 KB data flash, 24 KB RAM RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz, with ultra-low-power STOP mode (0.57 μA) and RTC+LVD operation - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101LKDFB#30 datasheet, R5F101LKDFB#30 pinout, R5F101LKDFB#30 application, or R5F101LKDFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, absence of on-chip data flash (R5F101x series), industrial-grade −40°C to +85°C operation (D-grade), and integrated 10-bit 26-channel ADC with temperature sensor.
Technical Context
The R5F101LKDFB#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, real-time clock with calendar/alarm, and watchdog timer driven by dedicated low-speed oscillator.
Peripherals include up to 16 channels of 16-bit timer, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM - all optimized for deterministic real-time control in resource-constrained environments.

FAQ
What is the flash memory configuration of the R5F101LKDFB#30?
The R5F101LKDFB#30 features 384 KB of on-chip code flash memory and no data flash memory - consistent with the R5F101x series designation indicating omission of dedicated data flash. This configuration prioritizes large program storage while relying on code flash sectors or external memory for parameter retention. The R5F101LKDFB#30 uses 1 KB flash blocks and supports self-programming with boot swap functionality.
Does the R5F101LKDFB#30 support real-time clock (RTC) operation in low-power mode?
Yes, the R5F101LKDFB#30 supports full RTC operation - including calendar, alarm, and clock correction - in STOP mode with only 0.57 μA typical current draw. This is achieved using the dedicated low-speed on-chip oscillator and independent RTC power domain, allowing timekeeping to persist while the CPU and most peripherals are powered down. The RTC remains functional even when VDD drops to 1.6 V.
What is the operating temperature grade of the R5F101LKDFB#30?
The R5F101LKDFB#30 is rated for industrial operation from −40°C to +85°C (D-grade), as indicated by the "D" in its part number suffix per Renesas' RL78/G13 ordering convention. It is not qualified for extended temperature ranges (e.g., −40°C to +105°C, G-grade) or consumer-grade (−40°C to +85°C, A-grade with different screening). This makes it suitable for factory automation, building controls, and outdoor industrial equipment.
Which package type does the R5F101LKDFB#30 use, and what are its dimensions?
The R5F101LKDFB#30 uses a 64-pin LFQFP package with 0.5-mm lead pitch, measuring 10 mm × 10 mm. The "FB" in the part number explicitly denotes this LFQFP-0.5mm variant, distinct from LQFP-0.65mm ("FA") or HWQFN ("NA") variants. Its footprint complies with JEDEC MS-026 standards and supports reflow soldering with standard profile IPC/JEDEC J-STD-020.
How many ADC channels and what resolution does the R5F101LKDFB#30 provide?
The R5F101LKDFB#30 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 on-chip temperature sensor - both accessible via dedicated ADC channels. The ADC operates across the full 1.6 V to 5.5 V supply range and supports scan mode, hardware trigger, and continuous conversion for sensor monitoring applications.
