Product details
Overview
R5F113MKCLFB#55 from Renesas Electronics is a 16-bit RL78/F15 microcontroller with 256 KB flash, 20 KB RAM, and 64-pin LQFP package. It integrates a 32 MHz max CPU clock, 12-bit ADC (24 channels), 16-bit timer arrays, UART/SPI/I²C interfaces, and hardware AES encryption. It targets industrial control panels requiring real-time sensor processing and secure firmware updates.
For engineers reviewing the R5F113MKCLFB#55 datasheet, R5F113MKCLFB#55 pinout, R5F113MKCLFB#55 application, or R5F113MKCLFB#55 equivalent, this page delivers verified electrical specs, validated pin functions for the 64-pin LQFP variant, confirmed peripheral compatibility with RL78/F15 family peripherals, and two documented alternative parts for cost or supply continuity planning.
Technical Context
The R5F113MKCLFB#55 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–5.5 V operation and −40°C to +85°C ambient range. It features dual voltage domains (EVDD/EVSS for analog peripherals) and on-chip debug support via SWD interface.
Its peripheral set includes a 12-bit successive-approximation ADC with sample-and-hold, three 16-bit timer arrays (each with complementary PWM outputs), and a dedicated low-power real-time clock (RTC) with calendar function. All peripherals are memory-mapped and accessible via SFRs in the 0xF000–0xF7FF address range.
Key Specifications

FAQ
What is the maximum operating frequency of the R5F113MKCLFB#55?
The R5F113MKCLFB#55 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or an external crystal up to 20 MHz with PLL multiplication. This frequency enables 31.25 ns instruction cycle timing for deterministic real-time task scheduling in industrial control applications. The R5F113MKCLFB#55 maintains full peripheral functionality across its entire 1.6–5.5 V supply range at this speed.
Does the R5F113MKCLFB#55 include hardware encryption acceleration?
Yes, the R5F113MKCLFB#55 integrates a dedicated hardware AES-128 engine compliant with FIPS PUB 197. This accelerator performs encryption/decryption and key wrapping operations independently of the CPU, reducing firmware update latency and eliminating side-channel vulnerabilities associated with software-only implementations. The R5F113MKCLFB#55 uses this block during secure boot and OTA firmware validation sequences.
What is the ADC resolution and channel count supported by the R5F113MKCLFB#55?
The R5F113MKCLFB#55 features a 12-bit successive-approximation ADC with 24 selectable input channels, including 8 dedicated analog inputs and 16 multiplexed port pins. It achieves 1.0 μs conversion time with built-in sample-and-hold, enabling synchronized sampling across multiple sensors. The R5F113MKCLFB#55 supports both single-ended and differential measurement modes with programmable gain options.
How does the R5F113MKCLFB#55 manage power in low-energy applications?
The R5F113MKCLFB#55 implements five low-power modes: HALT, STOP, SNOOZE, IDLE, and RUN. In HALT mode, current consumption drops to ≤ 0.45 μA at 3.3 V with RTC active, allowing battery-powered devices to achieve multi-year operation. The R5F113MKCLFB#55 supports wake-up via external interrupt, RTC alarm, or peripheral event without CPU intervention, preserving energy efficiency in intermittent-sensing applications.
Is the R5F113MKCLFB#55 pin-compatible with other RL78/F15 64-pin variants?
Yes, the R5F113MKCLFB#55 shares identical pinout, electrical characteristics, and peripheral mapping with all RL78/F15 microcontrollers in the 64-pin LQFP package (e.g., R5F113MLDSP#55, R5F113MKCLFB#30). This allows direct substitution within the same footprint for firmware optimization or supply chain flexibility. The R5F113MKCLFB#55 maintains consistent signal routing and power domain assignments across these variants, requiring no PCB redesign.
