FAQ

What is the maximum operating frequency of the R5F10BMECKFB#15?

The R5F10BMECKFB#15 operates at a maximum CPU clock frequency of 32 MHz. This speed is achievable using the on-chip high-speed oscillator (HOCO) or an external crystal up to 20 MHz with PLL multiplication. The device maintains full peripheral functionality-including CAN and LIN communication-at this frequency, with timing margins verified per Renesas RL78/F13 Hardware User's Manual Rev.2.20.

Does the R5F10BMECKFB#15 support CAN FD?

No, the R5F10BMECKFB#15 implements a classical CAN 2.0B controller only, supporting bit rates up to 1 Mbps and standard/extended identifier formats. It does not support CAN FD features such as flexible data-rate switching, increased payload length, or CRC enhancements. For CAN FD capability, Renesas recommends the RH850 or RA family devices-not the RL78/F13 series.

What is the purpose of the REGC pin on the R5F10BMECKFB#15?

The REGC pin on the R5F10BMECKFB#15 connects to an external 1 μF ceramic capacitor that stabilizes the output of the on-chip voltage regulator. This regulator supplies the internal core logic (1.8 V) and eliminates the need for an external LDO. Proper REGC capacitor placement-within 3 mm of the pin-is required to ensure stable operation across temperature and load conditions as specified in Renesas Application Note R01AN3529.

Can the R5F10BMECKFB#15 operate from a single 3.3 V supply?

Yes, the R5F10BMECKFB#15 supports single-supply operation from 3.3 V applied to VDD/EVDD0/EVDD1 pins. Its integrated regulator automatically configures internal voltage domains, and all I/Os remain 5 V tolerant. This simplifies power design in mixed-voltage systems and enables direct interface with 3.3 V sensors and communication transceivers without level shifters.

How many LIN channels does the R5F10BMECKFB#15 support?

The R5F10BMECKFB#15 supports exactly one LIN channel, implemented as a hardware LIN 2.2/2.3 controller with dedicated LIN_TX and LIN_RX pins. It handles all protocol layers-including break detection, sync field, identifier, checksum, and response timing-without CPU intervention, enabling reliable slave or master operation in automotive and industrial networks.
