FAQ

What is the maximum operating frequency of the R5F10BMGCLFB#35?

The R5F10BMGCLFB#35 supports a maximum CPU operating frequency of 32 MHz using the internal high-speed oscillator or external crystal. This frequency is achievable across the full industrial temperature range (−40°C to +105°C) when powered at 4.5–5.5 V, and enables real-time execution of CAN/LIN protocol stacks alongside application logic without timing bottlenecks.

Does the R5F10BMGCLFB#35 include a hardware real-time clock (RTC)?

Yes, the R5F10BMGCLFB#35 includes a fully integrated hardware RTC with calendar function (year/month/day/hour/minute/second), alarm interrupt, and periodic interrupt capability. It operates from the 32.768 kHz sub-clock input and retains timekeeping in STOP mode with typical current consumption of 1.2 µA - eliminating need for external RTC ICs in automotive modules.

Is the R5F10BMGCLFB#35 qualified for automotive applications?

Yes, the R5F10BMGCLFB#35 is AEC-Q100 qualified to Grade 2 (−40°C to +105°C ambient), with built-in BOR, POR, and watchdog timers. It meets automotive requirements for voltage tolerance (4.5–5.5 V), ESD immunity (±2 kV HBM), and EMC robustness - making it suitable for under-hood and cabin body control applications per Renesas' "High Quality" product classification.

How many CAN message objects does the R5F10BMGCLFB#35 support?

The R5F10BMGCLFB#35 supports 32 independent CAN message objects with configurable acceptance filtering, transmit/receive buffers, and priority-based arbitration. Each object can be individually configured for standard (11-bit) or extended (29-bit) identifiers, enabling flexible implementation of automotive CAN networks including diagnostics (UDS) and control messaging.

What development tools are supported for the R5F10BMGCLFB#35?

The R5F10BMGCLFB#35 is supported by Renesas' e² studio IDE, CS+ (formerly CubeSuite+), and the E2 Emulator Lite for debugging and flash programming. Hardware evaluation is enabled via the YRDKRL78F13 starter kit, which provides CAN/LIN transceivers, debug headers, and example projects for protocol stack validation and peripheral bring-up.
