It operates at up to 32 MHz, supports on-chip debug, and targets low-power industrial control and sensor interface applications.
For engineers reviewing the R5F113LLCKFB#35 datasheet, R5F113LLCKFB#35 pinout, R5F113LLCKFB#35 application, or R5F113LLCKFB#35 equivalent, this page delivers verified electrical specs, validated pin functions for the 64-pin LQFP variant, confirmed peripheral integration (ADC, UART, I²C, SPI), and real-world use cases in motor control feedback loops and smart metering subsystems.
Technical Context
The R5F113LLCKFB#35 implements the RL78 CPU core with 3-stage pipeline and CISC architecture optimized for ultra-low-power operation. It integrates a 12-bit successive-approximation ADC with sample-and-hold, 8-channel 16-bit timer arrays (including real-time clock and watchdog), and dual serial interfaces supporting UART, I²C, and CSI modes.
Power management includes three operating modes-High-speed (HS), Middle-speed (MS), and Low-speed (LS)-with sub-μA standby current and hardware-based voltage monitoring. The device uses Renesas' proprietary "Simplified Flash" technology enabling 100,000 write/erase cycles and 20-year data retention at 85°C.

FAQ
What is the maximum operating frequency of the R5F113LLCKFB#35?
The R5F113LLCKFB#35 supports a maximum CPU operating frequency of 32 MHz when powered within its specified 1.6 V to 5.5 V supply range. This frequency is achievable using the high-speed on-chip oscillator (HOCO) or an external crystal up to 20 MHz with PLL multiplication. The device maintains timing accuracy across temperature and voltage variations per its AC characteristics table in the RL78/F15 Hardware User's Manual (R01UH0559E).
Does the R5F113LLCKFB#35 include hardware-based security features?
The R5F113LLCKFB#35 does not integrate cryptographic accelerators or secure boot engines. Its security-related capabilities include RAM parity checking, dual independent watchdog timers, clock frequency monitoring, and low-voltage detection - all supporting functional safety compliance (IEC 61508 SIL2). For secure firmware updates or encrypted communication, external secure elements or software-based implementations are required alongside the R5F113LLCKFB#35.
Can the R5F113LLCKFB#35 drive standard LCD segments directly?
Yes, the R5F113LLCKFB#35 supports direct static and 1/2–1/4 duty LCD driving via its integrated LCD controller (LCDC), capable of driving up to 128 segments. This feature eliminates the need for external LCD driver ICs in applications such as smart meters and appliance displays. The LCDC operates independently of the CPU and supports internal bias generation and contrast adjustment through software-configurable registers.
What development tools are officially supported for the R5F113LLCKFB#35?
Renesas officially supports the R5F113LLCKFB#35 with the CS+ IDE (formerly CubeSuite+), e² studio (Eclipse-based), and the Renesas Flash Programmer (PG-FP6). Debugging is enabled via the on-chip debug interface (OCDS) using standard E1 or E20 emulators. The RL78/F15 Starter Kit (YRDKFX15) provides hardware reference and example code compatible with the R5F113LLCKFB#35 pinout and peripheral configuration.
Is the R5F113LLCKFB#35 qualified for automotive applications?
No, the R5F113LLCKFB#35 is classified as a Standard-grade Renesas product intended for industrial, consumer, and office equipment - not automotive transportation systems. It does not meet AEC-Q100 qualification requirements. For automotive body control or infotainment applications, Renesas recommends the RL78/F14 or RH850 families, which carry High Quality grade certification and extended temperature range (-40°C to +125°C) validation.
