FAQ
What USB modes does the R5F2134CKNFP#V0 support?
The R5F2134CKNFP#V0 supports USB 2.0 Full-Speed device, host, and OTG modes. Hardware-level OTG features include USB_ID pin for role detection, USB_EXICEN for external power IC control, and USB_VBUSEN for VBUS regulation-enabling automatic host/peripheral negotiation without software polling. This differs from the R5F21348KNFP, which only supports device mode.
Does the R5F2134CKNFP#V0 include hardware LIN support?
Yes, the R5F2134CKNFP#V0 integrates a dedicated hardware LIN module using UART0 and Timer RA to implement ISO 9141-2/SAE J2602 physical layer signaling. It generates automatic sync-break fields, supports configurable baud rates, and handles checksum calculation-offloading 100% of LIN frame processing from the CPU and reducing latency to <15 µs per byte.
What is the data flash endurance and BGO capability of the R5F2134CKNFP#V0?
The R5F2134CKNFP#V0 provides 10 KB of data flash organized in four 1 KB blocks, rated for 10,000 erase/write cycles. Its Background Operation (BGO) function allows full CPU execution-including interrupt servicing-during flash erase or program operations, enabling safe over-the-air firmware updates without system interruption or watchdog resets.
How many interrupt vectors does the R5F2134CKNFP#V0 support?
The R5F2134CKNFP#V0 supports 69 interrupt vectors with 7 priority levels. Sources include 9 external interrupts (INT0–INT4, KI0–KI3), 30 DTC activation triggers, and peripheral-specific events (USB, LIN, ADC EOC, timer overflows). Vector addresses are fixed in ROM at 0FFDCh–0FFFFh, ensuring deterministic latency under worst-case conditions.
What package and pin compatibility does the R5F2134CKNFP#V0 offer?
The R5F2134CKNFP#V0 uses a 48-pin LQFP package (PLQP0048KB-A / 48P6Q-A) with 0.5 mm pitch. It shares identical pinout and electrical characteristics with other R8C/34K Group MCUs like R5F21348KNFP and R5F2134CKDFP-enabling drop-in replacement within the same group when memory or temperature requirements change, provided USB OTG signals are unused in the design.
