Product details
Overview
R5F100LKGFB#V0 from Renesas is a 64-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 384 KB flash, 8 KB data flash, and 24 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), RTC with calendar/alarm, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LKGFB#V0 datasheet, R5F100LKGFB#V0 pinout, R5F100LKGFB#V0 application, or R5F100LKGFB#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, 384 KB code flash with self-programming and boot swap, 24 KB RAM for real-time task handling, and -40°C to +105°C industrial temperature rating (G-grade).
Technical Context
The R5F100LKGFB#V0 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 ultra-low-speed mode). 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 8-channel 16-bit timers, 12-bit interval timer, real-time clock with calendar and alarm, 2–4 channel DMA controller, 16×16/32÷32 multiplier/divider/MAC unit, and 3–10 channel I²C/Simplified I²C - all optimized for deterministic timing and low-latency interrupt response in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LKGFB#V0 | No data flash (0 KB); identical core, peripherals, and package - reduced nonvolatile storage for cost-sensitive fixed-parameter designs. | Suitable where firmware parameters are static or stored externally; eliminates BGO and flash shield window features. | Select when data logging or field-upgradable configuration is unnecessary and BOM cost reduction is prioritized. |
| R5F100LLAFA#V0 | LQFP-64 (0.65-mm pitch) instead of LFQFP-64 (0.5-mm pitch); same 384 KB flash, 8 KB data flash, 24 KB RAM, and G-grade temp range. | Compatible PCB layout with larger pitch eases hand-soldering and rework; slightly lower thermal performance due to thicker leadframe. | Choose for prototyping, low-volume production, or legacy assembly lines not equipped for 0.5-mm pitch QFP handling. |
Compared with R5F100LKGFB#V0, R5F101LKGFB#V0 removes data flash to cut cost and power, while R5F100LLAFA#V0 retains full functionality but uses a more manufacturable 0.65-mm pitch LQFP - offering trade-offs between integration density, field configurability, and assembly flexibility.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LKGFB#V0?
The R5F100LKGFB#V0 operates at up to 32 MHz with a peak performance of 41 DMIPS. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The device maintains this performance across its full 1.6 V to 5.5 V supply range and -40°C to +105°C industrial temperature grade, making R5F100LKGFB#V0 suitable for real-time control tasks such as motor commutation and protocol processing.
Does the R5F100LKGFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100LKGFB#V0 supports full in-system programming via its on-chip debug interface and boot swap function. It includes flash shield window protection and block erase prohibition to prevent unauthorized rewriting. The R5F100LKGFB#V0 also enables background operation during data flash updates, allowing uninterrupted application execution - critical for field-upgradable R5F100LKGFB#V0 deployments in remote equipment.
What analog capabilities does the R5F100LKGFB#V0 provide for sensor interfacing?
The R5F100LKGFB#V0 integrates a 10-bit ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor (active in HS mode). It supports single-ended and differential conversions with programmable sample-and-hold timing. These features allow direct connection of resistive sensors, thermistors, current shunts, and voltage dividers - eliminating external signal conditioning for many R5F100LKGFB#V0-based sensor front-ends.
How does the R5F100LKGFB#V0 achieve ultra-low-power operation in battery-powered applications?
The R5F100LKGFB#V0 achieves ultra-low-power operation through multiple low-power modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE (low-power peripheral operation with CPU halted). Its dedicated low-speed oscillator powers the RTC and watchdog independently, enabling precise wake-up timing without waking the core. This architecture extends battery life in R5F100LKGFB#V0-based wireless nodes and portable instrumentation far beyond competing MCUs.
Is the R5F100LKGFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LKGFB#V0 is pin-compatible with all other RL78/G13 devices in the 64-pin LFQFP-0.5mm package (e.g., R5F100LCAFB#V0, R5F100LLAFB#V0), sharing identical pin functions, electrical characteristics, and mechanical footprint. This allows drop-in replacement across memory variants (16–512 KB flash) and feature sets (data flash presence/absence) without PCB redesign - simplifying R5F100LKGFB#V0 migration and BOM rationalization.
