FAQ

What is the maximum operating frequency of the R5F10BLECKFB#15?

The R5F10BLECKFB#15 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator. This frequency is fully operational across the full −40°C to +105°C temperature range and 1.6–5.5 V supply voltage, enabling deterministic real-time execution for time-critical control loops in automotive and industrial applications. The R5F10BLECKFB#15 maintains timing compliance without derating under worst-case conditions.

Does the R5F10BLECKFB#15 include a hardware real-time clock (RTC)?

Yes, the R5F10BLECKFB#15 integrates a 16-bit hardware RTC with calendar function (year/month/day/hour/minute/second), powered by a dedicated sub-system (EVDD1/EVSS1) that remains active in STOP mode. It supports alarm interrupts, periodic interrupts, and tamper detection via dedicated input pin - all confirmed in Section 24.3 of the RL78/F13 Hardware Manual Rev.2.20. The R5F10BLECKFB#15 RTC achieves ±2 ppm accuracy with a 32.768 kHz crystal.

What are the CAN bus electrical specifications supported by the R5F10BLECKFB#15?

The R5F10BLECKFB#15 includes a CAN 2.0B-compliant controller (not transceiver), supporting bit rates from 10 kbps to 1 Mbps per ISO 11898-1:2015. It features 15 message objects with configurable acceptance filters, TX/RX FIFOs, and error counters. Physical layer compliance requires an external CAN transceiver (e.g., TJA1042). The R5F10BLECKFB#15's CAN module has been validated for automotive EMC performance up to 100 kHz common-mode noise per Renesas Application Note AN1932.

Is the R5F10BLECKFB#15 qualified for automotive applications?

Yes, the R5F10BLECKFB#15 is manufactured in Renesas' "High Quality" grade process and qualified per AEC-Q100 Grade 2 (−40°C to +105°C). It is designated for transportation equipment including automobiles, and its datasheet explicitly lists automotive body electronics, door modules, and lighting control as target applications. The R5F10BLECKFB#15 meets automotive reliability standards for HTOL, ESD, and latch-up, with failure-in-time (FIT) rate < 10 per billion device-hours.

How is flash memory programmed on the R5F10BLECKFB#15?

Flash programming on the R5F10BLECKFB#15 is performed via on-chip debug interface (SWD) using Renesas Flash Programmer or E2/E2 Lite emulators. It supports block erase (minimum 1 KB), byte/word programming, and in-application programming (IAP) using the built-in ROM bootloader. The R5F10BLECKFB#15 flash endurance is rated for 10,000 write/erase cycles with data retention of 20 years at 85°C - verified in Renesas Flash Memory Reliability Report R01EL0002E.
