Product details
Overview
R5F100LKDFA#V0 from Renesas is a 64-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 512 KB flash, 8 KB data flash, 32 KB RAM, 32 MHz operation (41 DMIPS), and ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock-targeted for industrial control panels requiring long battery life and deterministic timing.
For engineers reviewing the R5F100LKDFA#V0 datasheet, R5F100LKDFA#V0 pinout, R5F100LKDFA#V0 application, or R5F100LKDFA#V0 equivalent, key selection criteria include its 64-pin LQFP package with 512 KB code flash, industrial-grade -40°C to +85°C operation (D-grade), integrated data flash with 1M rewrite cycles, and support for SNOOZE mode for low-latency peripheral wake-up without CPU restart.
Technical Context
The R5F100LKDFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and 1 MB address space. Its memory subsystem includes on-chip debug, self-programming with boot swap, and background operation during data flash rewriting.
Power management includes on-chip POR, 14-level LVD with interrupt/reset options, HALT/STOP/SNOOZE modes, and a high-accuracy ±1.0% on-chip oscillator (1–32 MHz). Peripheral integration covers up to 16× 16-bit timers, 1× RTC with calendar/alarm, 1× watchdog timer, and DMA controller with 4 channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LKDFA#X0 | Identical silicon; differs only in packaging-embossed tape instead of tray (#V0) | No functional difference; selected for automated SMT line compatibility | Choose #X0 for high-volume pick-and-place; #V0 for prototyping or low-volume manual assembly |
| R5F101LKDFA#V0 | Omits data flash (0 KB); retains same core, peripherals, and package | Not suitable for applications requiring nonvolatile parameter storage or firmware update logging | Select R5F101LKDFA#V0 only when data flash is unnecessary-reduces cost and simplifies flash management |
Compared with R5F100LKDFA#V0, the #X0 variant offers identical electrical and functional behavior with tape-and-reel delivery, while R5F101LKDFA#V0 removes data flash to lower cost-making it viable only where runtime parameter persistence or field firmware updates are not required.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100LKDFA#V0?
The R5F100LKDFA#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V and -40°C to +85°C. The RL78 core's 3-stage pipeline and efficient CISC instruction set enable this throughput while sustaining ultra-low active current (66 μA/MHz).
Does the R5F100LKDFA#V0 include integrated data flash memory, and what is its endurance specification?
Yes, the R5F100LKDFA#V0 includes 8 KB of on-chip data flash memory, rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing program execution from code flash during data flash rewrites-a key enabler for robust firmware update and parameter logging in the R5F100LKDFA#V0.
What package type and pin count does the R5F100LKDFA#V0 use, and is it RoHS-compliant?
The R5F100LKDFA#V0 uses a 64-pin LQFP package (12 × 12 mm, 0.65-mm pitch), specified as PLQP0064JA-A. It is lead-free and fully RoHS-compliant. The #V0 suffix denotes tray packaging-optimized for evaluation and low-to-medium volume assembly-distinguishing it from tape-and-reel variants like #X0.
How does the SNOOZE mode in the R5F100LKDFA#V0 differ from STOP mode, and when should it be used?
SNOOZE mode in the R5F100LKDFA#V0 allows selected peripherals (UART, ADC, CSI) to remain active and generate interrupts while the CPU core is halted-enabling sub-microsecond wake latency. In contrast, STOP mode disables all clocks except RTC/LVD. Use SNOOZE when rapid peripheral response is needed (e.g., UART command receipt), and STOP when absolute minimum power is required between infrequent events.
Is the R5F100LKDFA#V0 qualified for industrial temperature range, and what grade designation confirms this?
Yes, the R5F100LKDFA#V0 is qualified for -40°C to +85°C operation under the "D" grade designation (industrial applications), as confirmed by Renesas' ordering part number structure and datasheet Section 1.1. This grade includes enhanced screening and validation for reliability in factory automation, motor control, and infrastructure equipment where ambient thermal stress is significant.
