FAQ

What is the maximum operating frequency of the R5F113PKCLFB#15?

The R5F113PKCLFB#15 supports a maximum system clock frequency of 32 MHz. This can be achieved using the internal high-speed oscillator (HOCO) or an external crystal/resonator up to 20 MHz with PLL multiplication. The CPU executes instructions at this rate with a 3-stage pipeline, delivering up to 22.4 MIPS at 32 MHz while maintaining low power consumption.

Does the R5F113PKCLFB#15 include hardware support for functional safety standards?

Yes, the R5F113PKCLFB#15 includes built-in hardware features for IEC 60730 Class B compliance, including ROM self-test, RAM march test, clock frequency monitor, and independent watchdog timer. These are documented in Renesas Application Note R01AN3829EU and supported by the Renesas Functional Safety Package (FSP) software library.

What package type and pin count does the R5F113PKCLFB#15 use?

The R5F113PKCLFB#15 is supplied in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This package matches the RL78/F15 64-pin product group and is compatible with standard SMT assembly processes and IPC-7351B land patterns.

Can the R5F113PKCLFB#15 operate from a single 3.3 V supply?

Yes, the R5F113PKCLFB#15 operates across a 1.6 V to 5.5 V supply range, fully supporting 3.3 V nominal operation. At 3.3 V, it achieves full 32 MHz performance with typical active current of 4.2 mA/MHz and retains all peripherals-including the 12-bit ADC, which maintains ±;1 LSB INL and DNL specifications across the entire voltage range.

Is there on-chip debug capability for the R5F113PKCLFB#15?

Yes, the R5F113PKCLFB#15 integrates a full-featured on-chip debug interface compliant with Renesas E2/E2 Lite emulators. It supports real-time trace, hardware breakpoints, memory/register access during halt or run mode, and non-intrusive debugging-without requiring external debug probes or dedicated debug pins beyond the standard SWD interface (pins P00/P01).
