FAQ

What is the maximum operating frequency of the R5F113PLCLFB#55?

The R5F113PLCLFB#55 supports a maximum CPU clock frequency of 32 MHz, achievable via its on-chip high-speed oscillator (HOCO), external crystal (1–20 MHz), or external clock input. This frequency is fully supported across the entire specified operating voltage range (1.6 V to 5.5 V), enabling deterministic real-time execution without external PLL circuitry. The R5F113PLCLFB#55 maintains timing compliance per Renesas' RL78/F15 Hardware User's Manual Rev.1.10.

Does the R5F113PLCLFB#55 include hardware debugging support?

Yes, the R5F113PLCLFB#55 integrates full-spec on-chip debug (OCD) capability compliant with Renesas' E2 Emulator and E2 Lite standards. It supports SWD interface, real-time trace, breakpoint setting, and memory access during halted or running states - eliminating the need for external JTAG emulators. This debug infrastructure is natively enabled in the R5F113PLCLFB#55 silicon and documented in Section 2.2.19 of the RL78/F15 Hardware User's Manual.

How many ADC channels does the R5F113PLCLFB#55 support, and what is their resolution?

The R5F113PLCLFB#55 integrates a single 12-bit successive-approximation ADC with 24 selectable input channels, including dedicated temperature sensor and internal reference voltage inputs. Channel selection, sampling time, and conversion trigger sources (software, timer, or peripheral event) are fully configurable via dedicated SFRs. This ADC capability is confirmed in Table 1.3 and Section 2.1.2 of the RL78/F15 Hardware User's Manual Rev.1.10 for 100-pin variants like the R5F113PLCLFB#55.

What power-saving modes are available on the R5F113PLCLFB#55?

The R5F113PLCLFB#55 offers three primary low-power modes: HALT (CPU stopped, peripherals active), STOP (CPU and most peripherals halted, RAM retained), and SNOOZE (selected peripherals active while CPU sleeps). In STOP mode with RTC enabled, current consumption drops to 0.52 µA - verified in Renesas' electrical characteristics table for the R5F113PL series. All modes support wake-up via external interrupt, timer match, or ADC completion, ensuring responsive low-power operation in the R5F113PLCLFB#55.

Is the R5F113PLCLFB#55 pin-compatible with other RL78/F15 100-pin variants?

Yes, the R5F113PLCLFB#55 shares identical pin configuration and function mapping with other RL78/F15 100-pin LQFP devices (e.g., R5F113PLCFB#55, R5F113PLDFB#55), as defined in Section 1.5.2 and Table 2.1.2 of the RL78/F15 Hardware User's Manual. Differences between these variants are limited to flash/RAM size and factory-programmed options - not pinout or electrical behavior - making them drop-in replacements within the same package variant.
