FAQ
What is the maximum operating temperature specification for the R5F10BBDLNA#G5?
The R5F10BBDLNA#G5 is rated for operation from −40°C to +105°C and is qualified to AEC-Q100 Grade 2 standards. This allows deployment in under-hood environments such as near fuse boxes or junction blocks where ambient temperatures exceed 85°C. The device maintains full functionality-including CAN/LIN communication, ADC accuracy, and flash programming-throughout this range.
Does the R5F10BBDLNA#G5 support hardware LIN bus arbitration?
Yes, the R5F10BBDLNA#G5 includes a dedicated LIN controller compliant with ISO 17987-4 that supports automatic header detection, checksum generation, and slave node response timing control. It handles LIN 2.2A frame formatting and synchronization without CPU intervention, enabling deterministic latency for body control applications.
Can the R5F10BBDLNA#G5 operate without an external crystal?
Yes, the R5F10BBDLNA#G5 can operate using its internal high-speed oscillator (IHOSC) running at 32 MHz, which is factory-trimmed to ±1% accuracy. This eliminates the need for an external crystal in cost-sensitive applications where LIN timing tolerance (±1.5%) and CAN bit timing margin are acceptable.
What debug interface does the R5F10BBDLNA#G5 provide?
The R5F10BBDLNA#G5 supports single-wire debug (SWD) via the RESET pin, enabling full JTAG-equivalent functionality-including breakpoints, memory access, and real-time variable monitoring-without requiring additional debug pins. This simplifies PCB layout and preserves I/O for application signals.
Is the R5F10BBDLNA#G5 pin-compatible with other RL78/F13 32-pin variants?
Yes, all RL78/F13 32-pin LSSOP devices-including R5F10BBDLNA#G5, R5F10BBGLNA#G5, and R5F10BBELNA#G5-share identical pin assignments, electrical characteristics, and package dimensions. This enables memory-size-based scalability without PCB redesign or firmware changes.
