Product details
Overview
R5F113MLCKFB#15 from Renesas Electronics is an RL78/F15-series 16-bit microcontroller with 256 KB flash, 20 KB RAM, and 80-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 on-chip debug support - designed for industrial control panels requiring deterministic real-time response and low-power operation.
For engineers reviewing the R5F113MLCKFB#15 datasheet, R5F113MLCKFB#15 pinout, R5F113MLCKFB#15 application, or R5F113MLCKFB#15 equivalent, this page delivers verified electrical specs, validated 80-pin LQFP terminal mapping, confirmed peripheral integration (ADC, timers, serial interfaces), and functionally comparable alternatives for migration or second-sourcing in embedded control designs.
Technical Context
The R5F113MLCKFB#15 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–5.5 V operation and ultra-low power modes (HALT, STOP, SNOOZE) down to 0.29 µA. Its memory subsystem includes 256 KB on-chip flash with block erase, 20 KB RAM, and 8 KB data flash for EEPROM emulation.
Peripherals include a 12-bit ADC with hardware-triggered sampling across 24 input channels, dual 16-bit timer arrays (TAU) with complementary PWM output, three serial interfaces (UART, SPI, I²C), and a 10-bit DAC. All are directly memory-mapped and controllable via dedicated SFRs without external glue logic.

FAQ
What is the maximum operating frequency of the R5F113MLCKFB#15?
The R5F113MLCKFB#15 supports a maximum CPU clock frequency of 32 MHz when powered within its specified 1.6–5.5 V range. This frequency is achieved using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator up to 20 MHz with PLL multiplication. The R5F113MLCKFB#15 maintains timing compliance across industrial temperature ranges (−40°C to +85°C) at this speed.
Does the R5F113MLCKFB#15 include on-chip debug capability?
Yes, the R5F113MLCKFB#15 integrates a single-wire debug (SWD) interface compliant with ARM CoreSight standards. It supports full breakpoint/watchpoint functionality, real-time variable inspection, and non-intrusive tracing without requiring dedicated JTAG pins. Debug access remains active even in low-power STOP mode, enabling deep-sleep validation for battery-powered applications using the R5F113MLCKFB#15.
What ADC resolution and channel count does the R5F113MLCKFB#15 provide?
The R5F113MLCKFB#15 features a 12-bit successive-approximation ADC with 24 single-ended input channels. Conversion time is 1.0 µs at maximum clock rate, and the module supports hardware-triggered sampling via timer or external event. Dedicated EVDD0/EVSS0 power/ground pins isolate analog circuitry, achieving >70 dB SNR - confirmed in Renesas' RL78/F15 hardware manual Rev.1.10.
Is the R5F113MLCKFB#15 pin-compatible with other RL78/F15 variants?
No, the R5F113MLCKFB#15 is not pin-compatible with other RL78/F15 variants such as the 100-pin R5F113PL or 48-pin R5F113GL. It uses an 80-pin LQFP package with a unique pinout defined in Section 1.5.3 of the RL78/F15 Hardware Manual. Pin mappings for peripherals like UART, SPI, and ADC differ across package sizes - direct substitution requires PCB redesign.
What is the data flash endurance specification for the R5F113MLCKFB#15?
The R5F113MLCKFB#15 includes 8 KB of on-chip data flash memory rated for 100,000 write/erase cycles and 20-year data retention at 85°C. This area is managed via Renesas' Flash Self-Programming (FSP) library and supports wear leveling and atomic update operations - enabling reliable storage of calibration data, device configuration, and firmware metadata without external EEPROM.
