FAQ

What is the maximum operating frequency of the R5F113PLCKFB#35?

The R5F113PLCKFB#35 supports a maximum CPU operating frequency of 32 MHz. This is achievable using the high-speed on-chip oscillator (HOCO), an external crystal (up to 20 MHz with PLL multiplication), or an external clock source. The device maintains full peripheral functionality-including ADC sampling and timer operations-at this speed, with timing margins verified across the full −40 °C to +85 °C temperature range.

Does the R5F113PLCKFB#35 include on-chip debug capability?

Yes, the R5F113PLCKFB#35 includes full on-chip debug support via the single-wire debug (SWD) interface compatible with Renesas E2 emulator and E2 Lite. Debug features include real-time variable watch, hardware breakpoints, flash programming, and memory inspection without halting peripheral operation - all accessible through standard IDEs including e² studio and CS+.

What package type and pin count does the R5F113PLCKFB#35 use?

The R5F113PLCKFB#35 uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This package maps to the RL78/F15 100-pin product group and provides 82 general-purpose I/O pins, including dedicated analog input channels, timer I/O, and communication interface signals as defined in the RL78/F15 User's Manual Hardware Rev.1.10.

Is the R5F113PLCKFB#35 qualified for industrial temperature operation?

Yes, the R5F113PLCKFB#35 is rated for industrial temperature operation from −40 °C to +85 °C. This qualification is specified in the official Renesas RL78/F15 datasheet and applies to all electrical characteristics, including flash endurance (100,000 write/erase cycles), ADC accuracy (±2 LSB INL), and timing parameters - with no derating required across the full range.

What are the key low-power features of the R5F113PLCKFB#35?

The R5F113PLCKFB#35 offers multiple low-power modes: HALT (0.7 µA), STOP (0.52 µA with RTC active), and SNOOZE (12 µA with ADC auto-triggering). It supports fast wake-up (<;3.5 µs from STOP), peripheral-triggered entry/exit, and independent clock gating per module - enabling energy-efficient operation in battery-powered and energy-harvesting applications without sacrificing real-time responsiveness.
