Product details
Overview
R5F100LKDFB#V0 from Renesas is a 64-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 384 KB flash, 8 KB data flash, 24 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), designed for industrial control, sensor nodes, and battery-powered HMI systems.
For engineers reviewing the R5F100LKDFB#V0 datasheet, R5F100LKDFB#V0 pinout, R5F100LKDFB#V0 application, or R5F100LKDFB#V0 equivalent, key selection criteria include its 32 MHz max CPU speed, integrated 10-bit 26-channel ADC, real-time clock with calendar/alarm, and support for LIN bus via UART - all within -40°C to +105°C industrial temperature grade.
Technical Context
The R5F100LKDFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 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, 3× I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, 2–8 CSI/SPI channels, DMA controller (2/4 channels), and hardware multiplier/divider. Memory subsystem supports background data flash rewriting (BGO) and self-programming with boot swap and flash shield window functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LKAFB#V0 | Same package and memory (384 KB flash, 24 KB RAM), but lacks data flash (0 KB); no BGO or self-programming support | Suitable only for fixed-parameter firmware where runtime data storage is unnecessary | Select when cost sensitivity outweighs need for field-updatable configuration storage |
| R5F101LKDFB#V0 | Identical pinout and package, but no data flash (0 KB) and reduced peripheral set (e.g., only 2 UARTs vs. 4) | Targeted at simpler control tasks without LIN, BGO, or advanced timer features | Choose for cost-optimized designs where data logging, LIN, or complex timing is not required |
Compared with R5F100LKDFB#V0, R5F100LKAFB#V0 removes data flash functionality - eliminating BGO and runtime parameter updates - while R5F101LKDFB#V0 reduces both data flash and serial interface count, trading flexibility for lower unit cost in deterministic control-only roles.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LKDFB#V0?
The R5F100LKDFB#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This value is derived from the RL78 CPU core's 3-stage pipeline and instruction mix benchmarking per EEMBC standards. The R5F100LKDFB#V0 achieves this performance while maintaining ultra-low active current consumption of 66 μA/MHz, making it suitable for compute-intensive yet power-sensitive applications.
Does the R5F100LKDFB#V0 support LIN bus communication, and how is it implemented?
Yes, the R5F100LKDFB#V0 supports LIN bus communication through its UART modules, which include hardware-assisted LIN break detection, sync field generation, and identifier verification. Up to four UART channels are available, with at least two configured for LIN 2.2 compliance. The R5F100LKDFB#V0 requires no external transceiver for basic LIN node operation - only a standard LIN physical layer driver - reducing system-level component count.
What are the data flash endurance and voltage requirements for write operations on the R5F100LKDFB#V0?
The R5F100LKDFB#V0 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full supply range of VDD = 1.8 V to 5.5 V. Write operations can be performed during normal program execution using Background Operation (BGO), and the flash library reserves specific RAM regions (e.g., F7F00H for R5F100xL variants) to manage rewrite routines safely.
How does the R5F100LKDFB#V0 handle power management in low-energy modes?
The R5F100LKDFB#V0 offers HALT, STOP, and SNOOZE modes with sub-μA quiescent current. In STOP mode with RTC and LVD enabled, it draws just 0.57 μA - verified across -40°C to +105°C. Wake-up sources include external interrupts, RTC alarm, and LVD threshold crossing. The R5F100LKDFB#V0 retains full register and RAM content during STOP, enabling instant resumption without reinitialization overhead.
Is the R5F100LKDFB#V0 pin-compatible with other RL78/G13 devices in the 64-pin LFQFP package?
The R5F100LKDFB#V0 shares identical pinout and footprint with all RL78/G13 64-pin LFQFP variants (e.g., R5F100LCAFB#V0, R5F100LLAFB#V0), including same power, ground, reset, and debug signal locations. However, peripheral mapping (e.g., UART/CSI/I²C channel assignment) varies across memory/configurations - so firmware must be validated for each specific part number even when hardware layout is reused.
