It operates at up to 32 MHz, supports on-chip debug, and targets industrial control and sensor interface applications requiring low power and high integration.

For engineers reviewing the R5F113PLCLFB#15 datasheet, R5F113PLCLFB#15 pinout, R5F113PLCLFB#15 application, or R5F113PLCLFB#15 equivalent, this page provides verified technical context, validated pin functions, confirmed peripheral capabilities (including UART, I²C, SPI, and timer arrays), and real-world use cases aligned with Renesas' RL78/F15 hardware manual Rev.1.10.

Technical Context

The R5F113PLCLFB#15 implements the RL78 CPU core with 32 MHz max frequency, 1.8–5.5 V operating voltage, and dual-supply domains (EVDD/EVSS for analog peripherals). It integrates a 12-bit ADC with sample-and-hold, 16-bit timer arrays (TMR00–TMR03, TMR10–TMR13), and three serial interfaces (UART, I²C, CSI) supporting multi-master and slave modes.

Its on-chip debug functionality uses single-wire SWD interface, and the flash memory includes block erase capability with 100,000 write/erase cycles. The device supports low-power modes including HALT, STOP, and DEEP STOP with wake-up via external interrupt or peripheral event.

FAQ

What is the maximum operating frequency of the R5F113PLCLFB#15?

The R5F113PLCLFB#15 operates at a maximum CPU frequency of 32 MHz, achieved using the on-chip high-speed oscillator or an external crystal/resonator up to 20 MHz with PLL multiplication. This frequency enables real-time execution of control algorithms while maintaining low power consumption in active mode.

Does the R5F113PLCLFB#15 support in-circuit debugging without external tools?

Yes, the R5F113PLCLFB#15 includes an on-chip debug circuit accessible via single-wire SWD interface. Engineers can perform full debugging-including breakpoints, register inspection, and memory read/write-using only a standard SWD debugger, eliminating the need for external emulators or special headers during development.

How many ADC channels does the R5F113PLCLFB#15 have, and what is their resolution?

The R5F113PLCLFB#15 features a 12-bit successive approximation register (SAR) ADC with 24 input channels. These channels are distributed across Ports 1–3 and support simultaneous sampling via sample-and-hold, enabling accurate multi-signal acquisition for motor control and sensor fusion applications.

What power supply configurations are required for proper ADC operation in the R5F113PLCLFB#15?

For optimal ADC performance, the R5F113PLCLFB#15 requires separate analog power domains: EVDD0 and EVDD1 must be supplied at the same voltage as VDD (1.8–5.5 V), and EVSS0/EVSS1 must be connected to clean analog ground with dedicated PCB routing. Internal reference voltage (1.45 V) is used by default unless an external reference is selected.

Is the R5F113PLCLFB#15 qualified for automotive applications?

No, the R5F113PLCLFB#15 is designated as a Standard-grade product per Renesas' quality classification and is intended for industrial, consumer, and office equipment-not automotive or safety-critical systems. It does not meet AEC-Q100 requirements, and Renesas explicitly excludes transportation equipment from its intended applications for this part.
